| Abstract: | This article aims to assess the impact of the Geographical Indications (GIs) protection policy on the sustainable development of agriculture in mainland France. More specifically, it analyses the impact over the last decade of the increase in the territorial magnitude of agri-food GIs on agricultural economic performance, agricultural employment and agricultural pressures on the environment (biodiversity and water quality). The magnitude of GIs is assessed using two distinct indicators: the proportion of farmers involved in GIs and the diversity of GI products within each territory. We use data at a fine territorial scale (cantonal level – NUTS4) and a meso-economic approach. We estimate a difference in differences econometric model to continuous variables, and we control for the effect of the presence of operators involved in organic farming in the territory, and of payments under the second pillar of the Common Agricultural Policy, which may impact sustainable development indicators. The results show that, all other factors being equal, cantons where there has been an increase in the presence of GIs over the last decade have seen greater improvements in their economic, social and environmental performance than cantons where there has been no increase. They also indicate the distinct and complementary effects of GI diversity and intensity in the territory, in terms of contribution to sustainable development. |

| Abstract: | Nepal remains among the countries most vulnerable to climate-related disasters. Although several national policy documents have emphasized the urgency of mitigation and adaptation, climate action remains fragmented and significantly underfunded. Nepal’s unique geography—spanning the Himalayas, mid-hills, and Tarai plains—together with recent decentralization reforms offers a favorable context for implementing localized, context-specific solutions to climate threats. However, the lack of consistent policy frameworks, weak institutional mechanisms, limited investment, and fragmented governance across all levels of government continue to impede progress. In this policy note, we use carbon trading in the forestry sector as a case study to illustrate broader policy challenges and opportunities in Nepal and other Global South countries. Trading is a market-based mechanism that incentivizes the offset of greenhouse gas (GHG) emissions through credits for CO2 sequestration.. Nepal has adopted this approach in line with international agreements such as the Kyoto Protocol and the Paris Agreement. As one of the major strategies, the country has sought to capitalize on its forest resources to generate carbon credits and attract international climate finance. |

| Abstract: | We combine 2008-2023 county-level yield data with 30-meter crop classification imagery to test whether crop diversity mitigates yield losses from weather shocks. Diversity is measured with the exponential Shannon index, capturing county-level species richness and evenness as the effective number of crops. Two-way fixed-effects regressions replicate standard nonlinear damages from extreme heat and precipitation, but show that each additional effective crop attenuates heat impacts for corn and soybean and moderates winter wheat losses in unusually wet years. Resilience benefits are concentrated in rainfed counties, where irrigation offers limited protection, indicating that diversification can complement water-based adaptation to climate change. |

| Abstract: | How does firms' skill demand change as the business landscape evolves? We present evidence from the green transition by analyzing how hurricanes impact demand for green skills. These disasters signal the risks of not acting on environmental issues. Using data from U.S. online job postings (2010--2019) and hurricane paths, we create a new measure of green job postings. Firms in areas affected by hurricanes are 6.4% more likely to post jobs that require green skills after the event, particularly those serving local markets. |

| Abstract: | Vietnam, a lower-middle-income economy, faces severe climate risks from heat waves, sea-level rise, and tropical cyclones, which are expected to intensify under ongoing global warming. Using a dynamic general equilibrium model, we analyze economic transition dynamics from 2015 to 2100, incorporating heat-induced labor productivity losses, agricultural land loss, and cyclone-related property damage. We compare a Paris-compatible scenario limiting warming to below 2 êC with a high-emission scenario reaching 4-5 êC. While output and investment impacts remain highly uncertain and statistically indistinguishable across scenarios until 2100, consumption losses are significantly larger under high emissions, mainly driven by heat-related productivity declines, with cyclones contributing most to uncertainty. These findings underscore the importance of considering multiple impact channels beyond output damages in climate-development research. |

| Abstract: | Aviation, crucial for global connectivity, significantly contributes to climate change, accounting for 2.5 percent of human-induced CO2 emissions and 3.5 percent of overall human-made changes to the energy balance in the Earth’s atmosphere. The sector’s CO2 emissions have doubled since the mid-1980s, with projections indicating a potential tripling of demand by 2050, underscoring the urgency of greener solutions to balance economic benefits with environmental impacts. However, challenges abound, such as the high costs and sustainability concerns of sustainable aviation fuel, the limited capabilities of alternative technologies, such as hydrogen and electric aircraft, and the need for extensive infrastructure and international collaboration. The report offers an overview of different alternatives for greener aviation and the associated challenges, discusses policy approaches, and highlights areas for future research to effectively reduce the sector’s environmental footprint. |

| Abstract: | New York State is currently planning for and implementing the New York Climate Leadership and Community Protection Act (CLCPA), which was passed in 2019 to promote renewable energy and battery storage, transportation electrification, building decarbonization, and climate resiliency and adaptation. The CLCPA directs the state to reduce statewide greenhouse gas (GHG) emissions by 40 percent by 2030 and 85 percent by 2050 (relative to 1990 levels)—and to achieve net-zero GHG emissions economy-wide. In meeting these targets, the state must prevent disproportionate burdens on disadvantaged communities (DACs) and prioritize GHG and copollutant reductions in DACs as defined by the Climate Justice Working Group. Additionally, Section 0117 of Article 75 of the Environmental Conservation Law, an environmental justice (EJ) provision of the CLCPA, requires that DACs receive at least 35 to 40 percent of climate investments and benefits.The CLCPA established the Climate Action Council to develop a framework for how the state could meet the CLCPA goals and commitments. In January 2023, the Council released its final Scoping Plan, which outlined strategies to achieve the GHG and net-zero emissions targets and increase renewable energy usage. A cap-trade-and-invest program was among the strategies identified as a tool that could help the state hit its emissions targets and generate revenue for climate action and investments. The New York State cap-trade-and-invest program is intended to encourage decarbonization by capping carbon emissions, requiring emitters to purchase allowances to emit, and subsidizing (the “invest” side) the adoption of low-carbon technologies such as heat pumps.Since early 2023, the governor and state have announced and focused on a cap-trade-and-invest program (“NYCI”) as a priority measure to reduce GHG emissions economy-wide. The state has named it the New York Cap-and-Invest or NYCI, however, regulatory agencies have expressed that there will be a form of trading so we refer to it as cap-trade-and invest to be clear about the program. Draft cap-trade-and-invest regulations are expected to be released by the Department of Environmental Conservation (DEC) and New York State Energy Research and Development Authority (NYSERDA) in mid-2024, with a public hearing and comment period to follow. As currently described by state agencies, cap-trade-and-invest will establish an auction for emissions allowances and allow entities to freely trade allowances in a secondary market, as in the economy-wide carbon cap-and-trade systems of California, Washington State, and the European Union (NYSERDA and DEC 2023). However, New York State’s cap-trade-and-invest must additionally meet the CLCPA’s explicit requirement to not disproportionately burden DACs and to prioritize emissions reductions in them. The preproposal released by NYSERDA and DEC in December 2023 offered some ideas about how the program might ensure benefits for DACs and highlighted its willingness to consider implementing facility-specific caps outside the cap-trade-and-invest program. The preproposal indicates that the caps would be administered separately under DEC and that the state is seeking additional guidance on how these caps might be implemented (NYSERDA and DEC 2023).Our research analyzes the emissions effects of different cap-trade-and-invest policy designs at the statewide and community level Communities are defined by census tracts in this analysis. in New York. The first policy design is a traditional cap-and-trade program with full trading allowed between sectors and with no facility-specific restrictions (the full trading case, or FTC). Because of modeling constraints, we were unable to model a case with carbon allowances that can’t be traded in a secondary market, Our modeling reflects a system with a free market for allowances because obligated entities will only pay up to their marginal cost of carbon abatement for a carbon allowance. In a system without a secondary market, entities may behave differently, or some allowances may end up stranded with obligated entities that cannot use them or sell them. We cannot capture these behaviors in our models. so the second case restricts trading through facility- and sector-specific caps designed to prioritize emissions reductions in DACs and limit their pollution burden (the restricted trading case, or RTC). Both the FTC and RTC obligate the power sector and are designed with caps that assume achievement of the 40 by ‘30 target mentioned above. We do not model all sectors, so we establish an emissions budget for the modeled sectors estimated to reflect economywide reductions under the 40 by ‘30 target (40 percent below 1990 levels by 2030). See Appendix E for more detail. The preproposal analysis released by the state signaled that the electricity sector may not be obligated to purchase allowances in New York state cap-trade-and-invest program but would be covered by the Regional Greenhouse Gas Initiative. We discuss how that policy may impact the interpretation of our results in the conclusion. Our analysis assesses the two policy designs and compares them with a business-as-usual (BAU) policy case where no economy-wide carbon pricing or trading policy is implemented.In this report, we provide GHG and copollutant emissions (fine particulate matter, PM2.5; nitrogen oxides, NOX; and sulfur dioxide, SO2) results, along with a variety of economic metrics. Air quality results, along with an additional policy case, will be forthcoming in a separate issue brief. In that analysis, we leverage a model that considers how direct emissions covered in this report combine, migrate, and settle into PM2.5 concentrations at the census tract level. The initial emissions analysis presented in this first report provides key insights on direct pollutants, particularly in the power sector, where our model provides detailed data at the latitude-longitude level about the proximity of copollutant emissions to DACs.Our analysis has revealed several insights:A cap-trade-and-invest program reduces carbon emissions in all modeled sectors beyond the baseline policies included in the BAU. Implementing either modeled cap-trade-and-invest system (FTC or RTC) yields an approximately 22 percent reduction in emissions from the BAU statewide in 2030.At facilities within one mile of a DAC, facility-specific caps (RTC) increase the average facility direct PM2.5 emissions reductions (from 2016) by nine percentage points, from 80 to 89 percent, compared with a scenario with a cap-trade-and-invest program that doesn’t include facility-specific caps. SO2 and NOX emissions behave similarly.The facility-specific caps included in the RTC reduce New York direct PM2.5 emissions within a mile from DACs on net by over 44, 000 pounds in 2030 (with significant reductions in SO2 and NOX emissions). The caps have virtually no impact on retail electricity prices.Sector-specific caps (RTC) that force greater emissions reductions in specific sectors reduce GHG emissions by 4 percent more in the residential sector (or 0.76 MMT CO2e) relative to a cap-trade-and-invest program with full trading across sectors (FTC).Sector-specific caps (RTC) that require fewer GHG emissions reductions in the transportation and power sectors lead to lower gasoline and residential electricity prices relative to a cap-trade-and-invest program with no sector-specific caps (FTC). Prices are lower by 10 cents per gallon and 30 cents per MWh respectively. The increase in average household heating costs is outweighed by the reduction in average household transportation costs.Our research demonstrates that cap-trade-and-invest policy design choices can affect the distribution and cost of GHG emissions reductions. Including facility-specific caps can ensure a minimum level of reductions for each facility without driving costs significantly higher, compared with not having facility-specific caps. Additionally, sector-specific caps with no trading between sectors can help ensure a minimum level of reductions in each sector while mitigating some important household costs. Our cost findings reflect the assumption that New York State will make generous investments in electrification subsidies for households. The details of a cap-trade-and-invest program, such as those we model, will determine whether New York State simultaneously achieves its GHG emissions goals, prevents disproportionate burdens in DACs from conventional pollution emissions and concentrations, and produces revenue that can sustain and drive climate action and investments by the state. For EJ stakeholders, this research is essential because they will not support a cap-trade-and-invest system that may further harm the health and quality of life for low-income communities and communities of color, which could violate Section 7(3) of the CLCPA. |

| Abstract: | The wildfire crisis in the western United States arises from the confluence of climate change, land-use patterns, and dense forest conditions. Federal land managers have responded by focusing management on reducing the density of forest vegetation and encouraging fire resilience through fuel treatments, including mechanical fuel treatments that remove woody biomass, often coupled with piling and burning. Treatments are costly and needs far outstrip available budgets, even after accounting for appropriations from the Bipartisan Infrastructure Law and Inflation Reduction Act. To improve the effectiveness of fuel treatment budgets, biomass removals might be sold as inputs to building materials or energy products, with revenues offsetting costs and extending area treated. Indeed, absent additional large appropriations, selling the biomass may be the only viable means to bring fuel treatments to an effective scale.However, managers have struggled to find willing buyers for this material. I examine the constraints affecting utilization of fuel treatment biomass (FTB) in the West based on a survey of relevant literature and arrive at several findings:At current prices, potential for biomass utilization at scale is limited to a few areas where existing production infrastructure intersects with areas of high wildfire risk. These market zones are where utilization strategies have the best chance to succeed.Crediting carbon offset values to utilization could greatly expand the economic feasibility of FTB utilization and the area of treatments, especially near active markets. Utilizing rather than burning FTB avoids carbon emissions and could be credited through voluntary and/or compliance markets.Crediting avoided health costs from smoke might also greatly expand the economic feasibility of FTB utilization and the area of treatments. Utilizing rather than burning FTB avoids health costs caused by smoke, especially additional PM2.5 emissions. Recent studies show that health benefits could be substantial— potentially much larger than carbon revenues in some places—but valuation and exchange protocols are not yet available.Transaction costs reduce the marketability of FTB on federal lands, though managers can moderate these costs through selection of contract instruments and terms.As currently designed, fuel treatments focus first on fire resilience and remove only small-diameter materials with low revenue potential. Forest managers can enhance the potential for utilization by offering a mix of this low-quality biomass and larger-diameter sawtimber.The report concludes with a set of actions that could expand the utilization of FTB in the West:To improve marketability of FTB, federal land management agencies can (1) analyze local demand to understand the reach and material requirements of existing and potential wood product manufacturers; (2) design treatment programs to balance utilization potential with ecological restoration and resilience objectives; and (3) use contract instruments that extend production periods but moderate transaction costs.To establish carbon credits for FTB utilization, agencies can (1) develop general carbon crediting protocols, likely patterned on the Climate Action Reserve’s draft biochar protocol; and (2) develop a protocol to certify federal FTB as a waste product.To support development of wood-based bioenergy demands, regulators can: (1) revise environmental regulations to allow FTB from federal lands to qualify as renewable feedstocks; and (2) develop low carbon fuel standard (LCFS) protocols specifically for the utilization of FTB.To advance understanding of the health implications of smoke from fuel treatments, agencies and NGO’s can convene experts from the health care and natural resource sectors to develop ways to estimate and value benefits and explore crediting mechanisms. |

| Abstract: | Many analysts have concluded that large amounts of atmospheric carbon dioxide (CO2) must be captured and permanently stored in the coming decades to meet international goals for arresting climate change, even with aggressive measures to limit greenhouse gas (GHG) emissions. The amount of carbon dioxide removal (CDR) needed to achieve net-zero GHG emissions poses a technological challenge, requiring significant advances in CDR capability and deployment. CDR at the needed scale will be expensive, particularly in the near term. It also can pose social and environmental challenges through spillover effects on communities, changes in land use, and major increases in electricity consumption. This report discusses the challenges for the United States in scaling up CDR, recommends immediate policy actions to improve and scale up CDR, and discusses longer-run policy frameworks through which CDR can play its necessary role for achieving net-zero GHG emissions in the United States by midcentury. In particular, we recommend—with important caveats—that CDR incentives be integrated with incentive-based mechanisms for GHG mitigation in the longer term.The “removal gap” is the amount of CDR needed to achieve policy targets for limiting temperature increase, given trajectories for GHG emissions and policies for their mitigation. As the size of the removal gap becomes clearer, so does the gap in removal policies. As observed in Smith et al. (2023), no countries have yet set removal goals. Current US policies encourage some CDR via subsidies for increased forest carbon storage, carbon capture and storage (CCS) with bioenergy, and direct air capture. A variety of recent policy measures, including financial incentives in the 2022 Inflation Reduction Act, are providing increased CDR stimulus. However, the size of the removal gap and the policy focus on near-term initial investments versus longer-term technological development and scaling up indicate a need to fortify current policies and consider longer-term policies to induce the required amounts of CDR capacity.Notably, the nature and design of policies to motivate and finance the necessary levels of CDR have received little attention, an oversight that is increasingly recognized (Honegger 2023; Meyer-Ohlendorf and Spasova 2022; Schenuit et al. 2021). An exception focused on BECCS deployment is Zetterberg et al. (2021). Recent studies on the need for CDR make these observations:“There is an urgent need for comprehensive policy support to spur growth in CDR” (Smith et al. 2023, 39).“CDR at anywhere approaching the scales projected here would require strong policy incentives … and public investment …” (Fuhrman et al. 2023, 9).Substantially scaling up global CDR by midcentury will be a technological challenge. It will also be a challenge for climate policy. Core policy questions include the following:How can policies create the incentives needed for private provision of CDR at a large scale over the long term?If private sector investment in CDR remains limited by high cost or other constraints, what might the government do to scale up CDR?What policies would improve CDR technologies and lower their cost over time?How do CDR and GHG emissions reduction policies interact, and what are the implications for CDR policy design?This report also addresses complementary policies to deal with a range of other issues that arise in scaling up different CDR approaches:What measures can address the environmental and social consequences of CDR and thus ameliorate the negative community reactions that otherwise may result?Beyond technological and economic barriers, what other barriers to CDR deployment need to be addressed? Two examples: health and safety measures, and the siting and regulation of industrial capture facilities, GHG storage facilities, and CO2 pipelines.Our focus is US policy, though important aspects of our analysis are also relevant for other countries. In addition, US policy will trigger international questions, such as whether CDR projects abroad can be used by US emitters to offset their emissions. The United States should play a leading role in CDR deployment and policy development because it is the second-largest global GHG emitter, with a correspondingly large need to counteract residual emissions. In addition, the United States is in a strong competitive position to produce CDR, given its wealth, robust institutions, capacity for technological innovation, and large land mass suitable for nature-based removal and storage infrastructure. The United States also has an existing, though limited, suite of removal incentives on which to build.The report is organized as follows. Section 2 explains the urgent necessity for carbon dioxide removal as a complement to emissions reductions. Section 3 looks at the various technologies that can deliver CDR, their development status, and their costs. Section 4 lays out the criteria by which we analyze current and recommended CDR policies. Section 5 reviews today’s US CDR policies and highlights policy gaps, weaknesses, and other barriers to CDR deployment.Section 6 makes recommendations for new policies and modifications of existing policies to accelerate CDR technology development and larger-scale CDR investments. It also makes recommendations for addressing CDR’s environmental and other community effects, and it suggests complementary policies related to, for example, permitting CO2 pipelines and storage facilities. The recommendations in Section 6 can be thought of as a policy “on-ramp” that can facilitate the transition to a policy architecture consistent with net-zero ambitions. However, the policy steps discussed in Section 6 will not drive sufficient CDR investment to meet net-zero goal.Section 7 explores the more ambitious midcentury CDR policy architecture needed to continue the transition to net zero and compares the options in terms of cost-effectiveness, equitability, and feasibility. Section 8 concludes with some final observations. |

| Abstract: | Climate change is the defining environmental problem of our time. Recent assessment reports from the Intergovernmental Panel on Climate Change and the US government have highlighted the urgency of reducing greenhouse gas (GHG) emissions to net zero (and beyond) in the next few decades to avoid the most catastrophic effects of climate change.Eliminating GHG emissions throughout the global economy will entail comprehensive actions to reshape society’s approach to producing and using energy. Shifting to complete reliance on low- and zero-emissions sources of energy will require substantial investments in technology and infrastructure. Such investments could simultaneously drive economic growth and deliver environmental benefits in disproportionately impacted communities. We use the term disproportionately impacted communities throughout this report to refer to both overburdened and underserved communities, as defined by Maryland’s Climate Solutions Now Act (CSNA). Accomplishing a rapid energy transition—and doing so in a way that seizes the economic opportunity of that transition—will require a supportive policy framework.The state of Maryland has already taken significant policy steps to guide its own transition. Reductions in emissions from the power sector are guided by Maryland’s membership in the Regional Greenhouse Gas Initiative (RGGI) and further supported by the state’s renewable portfolio standard (RPS). Efforts to address transportation emissions include the forthcoming Advanced Clean Cars II rule, under which the share of zero-emissions vehicles will reach 100 percent of new-vehicle sales by 2035, and the Advanced Clean Truck rule (effective in 2027). Building energy performance standards will require a 20 percent reduction in direct GHG emissions from existing large buildings by 2030, relative to 2025.Maryland’s efforts to reduce emissions also benefit from existing sector-specific federal mitigation policies: for the power sector, tax credits for solar, wind, and other low-carbon generation; for the transportation sector, electric vehicle and sustainable fuel credits, electric vehicle infrastructure investments, and GHG emissions standards for light-, medium-, and heavy-duty vehicles; for the residential sector, energy efficiency home tax credits and other consumer tax credits; and for the industrial sector, incentives for clean hydrogen and carbon capture and storage.As required by the Climate Solutions Now Act (CSNA), the Maryland Department of the Environment (MDE) released its Climate Pollution Reduction Plan in December 2023, outlining policy actions to reach the state’s ambitious climate goals: reducing GHG emissions by 60 percent from 2006 levels by 2031, achieving 100 percent clean energy by 2035, and reaching net-zero emissions by 2045. Highlights of the plan include the following:completing the transition away from coal-fired power plants;scaling up renewable infrastructure, including solar, wind, and battery power;providing more incentives for consumers to choose electric when they replace vehicles and expanding charging infrastructure;advancing energy-efficient retrofitting of 9, 000 existing buildings and helping consumers electrify their homes by switching to heat pumps, electric water heaters, and electric appliances; andelectrifying school buses, transit buses, and government fleet vehicles.As part of the plan, MDE has committed to explore an economy-wide cap-and-invest program “to complement targeted investments and sectoral standards, while providing a sustainable revenue source for state-funded community investments.” The program would aim to drive investments in energy infrastructure that enable reductions in climate pollution, to place a declining cap on such pollution, and to auction emissions allowances to raise proceeds to support program-related goals. The program could prioritize investments in disproportionately impacted communities. Further, it could provide resources to make the transition affordable for businesses and households.This report outlines options for the design of such an economy-wide cap-and-invest program. We draw on both policy science literature and experience in existing emissions markets. Market-based mechanisms that place a price on emissions are an effective tool to incentivize cost-effective emissions reductions because they give private parties the flexibility to reduce emissions where it is least expensive to do so. An emissions cap boosts confidence that the climate plan goals, and the overall emissions reduction target, will be achieved. Adding the investment framework can provide incentives to leverage federal and private funds to achieve the goals and place equity for small businesses and low- and moderate-income households at the front of the energy transformation. However, in designing this emissions cap-and-invest program, policymakers face many decisions that will influence its fairness, effectiveness, and enforceability. |

| Abstract: | In Climate Insights 2024: American Understanding of Climate Change, we showed that huge majorities of Americans believe that the earth has been warming, that the warming has been caused by human activity, that warming poses a significant threat to the nation and the world—especially to future generations—and that governments, businesses, and individuals should be taking steps to address it.In this report, we turn to specific federal government opportunities to reduce future greenhouse gas emissions, often referred to as climate change mitigation. Policies to accomplish this goal fall into several categories, including:Consumer incentives that reward people for taking steps that reduce their use of fossil fuels and, by extension, reduce their carbon footprintCarbon pricing policies that require emitters to pay for their carbon emissions, such as a carbon tax (which would require carbon emitters to pay a tax for each ton of carbon they emit), or a cap-and-trade program (which would require businesses to have a permit for each ton of carbon they emit)Regulations that require manufacturers to increase energy efficiency of their productsTax incentives that encourage manufacturers to increase the energy efficiency of their productsThis 2024 survey asked Americans about their opinions on a wide array of such policies, which allows us not only to assess current opinions, but to track changes in those opinions over the past two decades through comparisons with responses to comparable questions asked in earlier national surveys. |

| Abstract: | Our country and New York State (NYS) in particular are striving to meet the interrelated challenges of decarbonization and environmental justice. Historically unjust systems and policies have led to a disproportional air pollution burden on low-income communities and communities of color. As a result, the federal and NYS governments have resolved to meet their climate goals while improving air quality conditions in disadvantaged communities.Bringing together leading environmental justice advocates, economic researchers, public health scientists, and air quality modelers, Resources for the Future (RFF) and the New York City Environmental Justice Alliance (NYC-EJA) along with researchers at Yale, UC Davis, and Northeastern University have partnered to investigate local air quality impacts on disadvantaged communities from implementation of the NY Climate Leadership and Community Protection Act (CLCPA). Specifically, we compare two sets of policies, both in line with the statutory requirements of the law but differing in their ambition and the degree to which they focus on aiding disadvantaged communities, with a business-as-usual (control) case in 2030. One policy case (inspired by recommendations of the Climate Action Council, CAC) models what the New York State government may implement, which includes policies discussed in other jurisdictions and proposed by New York policymakers. The other case (representing what many stakeholders recommend) was crafted by a team led by NYC-EJA and included many environmental and climate justice advocates in New York, who prioritized community protection and directing benefits to marginalized communities. We modeled the impact of policies on the electric power, on-road transportation, ports, and residential building sectors; the effects these policies have on emissions of direct fine particulate matter (PM2.5) and its precursors nitrogen oxides, sulfur dioxide, and volatile organic compounds (NOx, SO2, and VOCs); and the resulting PM2.5 concentrations experienced by disadvantaged communities and nondisadvantaged communities alike. For a full list of policies modeled, see Table 1 in our full report. |

| Abstract: | We explore the interplay between two key individual drivers of green consumption: intrinsic moral concerns for the environment and reputational concerns for social image. Our microeconomic behavioral model characterizes choices among lifestyles differing in environmental impacts (brown/green) and conspicuousness (positional/discreet), depending on how strongly one values each of these motives. We show that image concerns can substitute for environmental concerns in driving green consumption across a limited but central range of preferences, in particular through the purchase of green positional goods. Such conspicuous conservation can green individual consumption (reconciling Eco and Ego), especially among image-sensitive consumers, but it yields environmental benefits only under specific economic conditions. Indeed, the environmental impact of a lifestyle depends critically on its relative impact intensity, i.e., the pollution per dollar spent on this lifestyle, more than on the pollution per unit of the representative good of the lifestyle, driving volume effects and behavioral rebound effects, which both reduce the environmental benefits of green lifestyles. Knowing the collective distribution of preferences may help design targeted policies, as those preferences strongly determine policy effectiveness. Our findings are especially relevant for policies that aim to foster greener consumption choices in different economic contexts (e.g., green nudging, environmental taxes with higher rates on positional goods...). |

| Abstract: | In this paper, using the Bayesian VAR framework suggested by Chan et al. (2025), we produce conditional temperature forecasts up until 2050, by exploiting both equality and inequality constraints on climate drivers like carbon dioxide or methane emissions. Engaging in a counterfactual scenario analysis by imposing a Shared Socioeconomic Pathways (SSPs) scenario of "business as-usual", with no mitigation and high emissions, we observe that conditional and unconditional forecasts would follow a similar path. Instead, if a high mitigation with low emissions scenario were to be followed, the conditional temperature paths would remain below the unconditional trajectory after 2040, i.e. temperatures increases can potentially slow down in a meaningful way, but the lags for changes in emissions to have an effect are quite substantial. The latter should be taken into account greatly when designing response policies to climate change. |

| Abstract: | Whereas hydrogen is currently a marginal energy carrier, the aim of the EU is to trigger low-carbon hydrogen production that covers around 10 percent of EU’s energy needs by 2050. If this comes true, it will be an energy revolution. We study competition between green and blue hydrogen by proposing a Salop model that encompasses the value chains for hydrogen and CCS. For blue hydrogen, we distinguish between central production—natural gas is transformed to hydrogen close to the extraction site and hydrogen is then transported over a long distance via terminals to the hydrogen consumers—and local production—natural gas is transformed to hydrogen at terminals located near the hydrogen consumers. We find that mark-ups are highest under central blue hydrogen production, which implies that total production of hydrogen, supply of blue hydrogen, and share of plants investing in carbon capture facilities are lower under central production than under local production of blue hydrogen. We provide numerical simulations of the alternative market outcomes and also the corresponding social outcomes, and calculate the magnitude of policy instruments that should be used in order to obtain the social outcomes under central and local blue hydrogen production. |

| Abstract: | The European Green Deal (EGD) has the intention to transform the EU into a sustainable, resource efficient and competitive economy, ensuring zero net emissions of greenhouse gases (GHG) by 2050. This article illustrates the complex regulatory architecture of the EGD, which is often overlooked. While each of the initiatives is reasonable, their combined impact - often reinforcing each other - could impede Europe's global competitiveness, especially in a fragile economic environment. There are some fields where a thoughtful discussion about implementation deadlines and reporting requirements could help to resolve trade-offs between environmental objectives and competitiveness. |

| Abstract: | The unfolding climate crisis is triggering the emergence of new regulatory tools to support banks in the management of risks related to policy, technological and customer behaviour change in the transition to a sustainable low-carbon economy. These, especially transition plans, seek to improve the ability of banks and supervisors to identify, mitigate and manage the short-, medium- and long-term risks associated with climate and environmental risks at the individual institution level and the financial system as a whole. This report draws on the parallels between recovery and transition planning to identify lessons relevant for policymakers and regulators working on bank transition plans, focusing on internal bank governance, supervisory processes and cross-border coordination in the European Union. |

| Abstract: | This study examines the sustainability and healthiness of Ghana's current dietary patterns and explores pathways for promoting sustainable healthy diets through agrifood policy interventions. Using secondary data from the Food and Agriculture Organization's Statistics, Ghana Statistical Service, and other sources, the study assesses food security dimensions, estimates greenhouse gas emissions from current diets, analyzes the relationship between income and meat consumption, and generates Pareto-optimal dietary solutions. The analysis reveals significant dietary imbalances: Ghanaians overconsume staple foods (279 percent of recommended levels) and severely under-consume fruits (57 percent); vegetables (43 percent); and legumes, pulses, and nuts (20 percent). Despite adequate national caloric availability (135 percent adequacy), 63 percent of the population cannot afford healthy diets, with 21.1 million people facing affordability constraints. Ghana's current dietary patterns generate 46 million metric tons per year of greenhouse gas emissions and fail to meet international sustainability targets, with a positive correlation (0.3 percent increase per 1, 000 GHS income) between economic development and meat consumption. Pareto optimization demonstrates that although government dietary guidelines can achieve up to 32 percent emissions reduction at higher costs, EAT-Lancet recommendations offer superior outcomes with 47 percent lower costs and 70 percent lower emissions. The policy landscape analysis spanning 2014–23 reveals progress from food security–focused to holistic approaches incorporating nutrition and sustainability. Key recommendations include revising national dietary guidelines to align with sustainability targets, enhancing production support for diverse crops, improving food system infrastructure, and developing sustainable protein transition policies to decouple economic growth from increased environmental impacts. |

| Abstract: | Spatially customized land management strategies are crucial for mitigating land degradation and fostering effective landscape restoration. A deep understanding of local biophysical conditions ensures that interventions are both contextually relevant and impactful, promoting long-term environmental sustainability and delivering socio-economic benefits to local communities. With this consideration, this report, drawing on data collected through field surveys, GIS, and remote sensing techniques, uses Halaba, Ethiopia, as a case study to highlight the region’s varied biophysical conditions and their implications for the design and planning of sustainable land management (SLM) practices. This document is intended for agricultural and natural resource management professionals involved in the design, planning, implementation, and monitoring of SLM practices. |

| Abstract: | To study the economic and welfare consequences of alternative time paths towards net zero CO2e emissions, we develop a multi-sector dynamic computable general equilibrium model of an open economy with heterogeneity in abatement costs across sectors and firms and with adjustment costs in the adoption of abatement technologies and other types of investment. We measure the welfare costs of following the simple rules for emissions reduction observed in practice rather than the optimal national policy rule prescribed by economic theory. In an undistorted economy subject to a carbon budget, the theoretically optimal climate policy is a "Hotelling rule" where the carbon tax rate increases year by year at the real rate of interest. However, when some consumers are credit-constrained, it is optimal to deviate from the Hotelling rule and use carbon taxation to redistribute income towards poor hand-to-mouth consumers. Nevertheless, in aggregate terms very little welfare is lost by following a Hotelling rule or a linear emissions reduction path rather than the optimal time path for carbon taxes when climate policy is subject to a carbon budget. The optimal carbon tax path towards a simple end-point target for net zero emissions implies a much higher welfare cost per ton of accumulated GHG emissions than a policy constrained by a carbon budget. |

| Abstract: | Building on the analyses in chapters 3 and 4, this section focuses on quantifying other external vulnerabilities that the Colombian economy is facing, i.e., its exposure to other global economic dynamics. In a context where fiscal pressures have been aggravated by uncertainties related to the pandemic, inflation, and supply chain disruptions, this chapter addresses through various empirical scenarios how a credit rating downgrade (change in country risk perception) and the Evergrande bankruptcy could further impact Colombia's ability to finance its energy transition by raising borrowing costs and dampening investment and consumption. The simulation results indicate that a 120 basis point increase in the EMBI could lead to a decrease in GDP growth (lowering it from an expected 3% to 2%). Additionally, investment could fall by 0.5 percentage points and inflation could slightly increase from 3.0% to 3.05%. The country's international reserves are also expected to decrease by 1.5% long-term, reflecting the deterioration in Colombia's external accounts as a result of the need to finance the increase in the fiscal deficit. The simulation results therefore emphasise the necessity of sustainable financing mechanisms to support the energy transition. Policy options, including carbon taxes and green bonds, are discussed as viable strategies to mobilise resources for green infrastructure, enhancing fiscal stability and attracting foreign investment. Ultimately, the chapter shows that securing fiscal stability is vital for instilling confidence in international markets, mitigating risks, and fostering economic resilience. |
| Abstract: | Partiendo de los análisis de los capítulos 3 y 4, en los que –entre otros– se examinaron los impactos macroeconómicos de la disminución de las exportaciones colombianas de hidrocarburos en el contexto de una transición global hacia una economía baja en carbono, esta sección se centra en cuantificar otras vulnerabilidades externas a las que se enfrenta la economía del país, es decir, su exposición a otras dinámicas económicas globales. En un contexto en el que las presiones fiscales se han visto agravadas por las incertidumbres relacionadas con la pandemia, la inflación y las interrupciones de la cadena de suministro, el capítulo aborda a través de varios escenarios empíricos cómo una rebaja de la calificación crediticia (cambio en la percepción del riesgo país) y la quiebra de Evergrande podrían afectar aún más a la capacidad de Colombia para financiar su transición energética al aumentar los costes de endeudamiento y frenar la inversión y el consumo. Los resultados de la simulación muestran que un aumento de 120 puntos básicos en el EMBI podría provocar una disminución del crecimiento del PIB (reduciéndolo del 3% al 2%). Además, la inversión podría disminuir en 0, 5 puntos porcentuales y la inflación podría incrementarse ligeramente del 3, 0% al 3, 05%. También se prevé que las reservas internacionales del país disminuyan un 1, 5% a largo plazo, lo cual refleja el deterioro de la cuentas exteriores de Colombia como resultado de la necesida de financiar el aumento del déficit fiscal. El capítulo explora, por lo tanto, los resultados de las simulaciones que enfatizan la necesidad de mecanismos de financiación sostenibles para apoyar la transición energética. Se discuten opciones políticas, incluidos los impuestos sobre el carbono y los bonos verdes, como estrategias viables para movilizar recursos para infraestructuras verdes, mejorando la estabilidad fiscal y atrayendo inversiones extranjeras. En última instancia, el capítulo muestra que garantizar la estabilidad fiscal es vital para infundir confianza en los mercados internacionales, mitigar los riesgos y fomentar la resiliencia económica. |

Dans un contexte où les pressions budgétaires ont été aggravées par les incertitudes liées à la pandémie, à l'inflation et aux perturbations de la chaîne d'approvisionnement, le chapitre examine, à l'aide de divers scénarios empiriques, comment un abaissement de la note de crédit (changement dans la perception du risque pays) et la faillite d'Evergrande pourraient avoir un impact supplémentaire sur la capacité de la Colombie à financer sa transition énergétique, en augmentant les coûts d'emprunt et en freinant l'investissement et la consommation. Les résultats de la simulation montrent qu'une augmentation de 120 points de base de l'indice EMBI pourrait entraîner une diminution de la croissance du PIB (passant des 3 % attendus à 2 %). En outre, l'investissement pourrait diminuer de 0, 5 point de pourcentage et l'inflation pourrait augmenter légèrement de 3, 0 % à 3, 05 %. Les réserves internationales du pays devraient également diminuer de 1, 5 % à long terme, reflétant la détérioration des comptes extérieurs de la Colombie en raison de la nécessité de financer le déficit budgétaire croissant. Les résultats des simulations soulignent ainsi, la nécessité de mécanismes de financement durables pour soutenir la transition énergétique. Des options de politiques publiques, notamment les taxes sur le carbone et les obligations vertes, sont présentées comme des stratégies viables pour mobiliser des ressources pour les infrastructures vertes, renforcer la stabilité fiscale et attirer les investissements étrangers. Le chapitre insiste particulièrement sur l'importance de garantir la stabilité fiscale pour inspirer la confiance sur les marchés internationaux, atténuer les risques et favoriser la résilience économique. |

| Abstract: | We build a signaling game model of a firm’s decision to acquire a costly green label which enables it to emit a green bond. A greenium may compensate it for the incurred cost. That cost is higher for non-green firms. With an investor that prefers a clean environment and dislikes being fooled into believing in a fabricated green label, there are equilibria featuring green bonds by either both firm types, only the green firm or neither. Allowing side payments undermines stability of all equilibria where a green label is acquired. A neutral rather than a green investor considerably decreases the number of conceivable equilibria, as does uncertainty about the investor type. The equilibria of the baseline model are preserved if we allow two investors, a green and a neutral one, to decide on their respective purchase of the bond sequentially. Lastly, if investors hold all market power, no green labels will be observed at all. |

| Abstract: | The social cost of greenhouse gases (SC-GHG) is an estimate of the economic cost to society of an incremental metric ton of emissions of a given greenhouse gas. Recent advances in SC-GHG estimates represent a major step forward towards a comprehensive accounting of the impacts of greenhouse gases, yet they still omit important impacts of climate change such as its effects on ocean ecosystems and fisheries. As a step towards incorporating ocean system impacts into SC-GHG estimates, researchers at Resources for the Future (RFF) and their colleagues convened a group of 40 scientists and policymakers for a series of three strategic workshops. The first workshop served to level-set participants on state-of-the-art SC-GHG modeling, using the RFF-Berkeley Greenhouse Gas Impact Value Estimator (GIVE) model as an example. The second and third workshops focused on two topics identified as priority areas: coral reefs and fisheries. Key topics of discussion included: i) available statistical techniques well suited to the complexities of ocean ecosystems and economies, ii) the importance of the compounding effects of multiple stressors such as temperature increases, extreme events, and ocean acidification on coral reefs and how to capture them in projections of future climate scenarios, and iii) approaches to modeling recreational and commercial fisheries while accounting for economic dynamics such as substitution effects and hedonic adaptation, as well as resource-driven geopolitics. This report documents the dialogue from the workshops, serving as reference material for continuing collaboration to incorporate ocean impacts into more comprehensive SC-GHG estimates. |

| Abstract: | This paper investigates the sensitivity of Genuine Savings (GS), a widely used economic indicator of sustainable development, to methodological choices in practical wealth accounting. Using a sample of 33 countries and two major international datasets (World Bank and AMECO), theoretically equivalent but methodologically distinct savings-based (GS) and investment-based (GI) approaches are compared. The results show that substantial discrepancies can arise between GS and GI estimates, both across and within the datasets. Disparities generally exceed the magnitude of the key environmental adjustments in standard GS calculations and can result in conflicting sustainability signals. We highlight internal savings-investment consistency issues, particularly within the World Bank dataset, and demonstrate that, despite theoretical equivalence, the GS and GI estimates can diverge considerably in practice. Our findings suggest that policymakers using wealth-based indicators should shift focus from a binary interpretation (positive = sustainable, negative = unsustainable) to identifying persistently low savings levels. More broadly, it is important to conduct internal consistency checks for robust empirical assessments of sustainable development. |

| Abstract: | Proton exchange membrane electrolysis (PEMEL) is a key technology for producing green hydrogen, but its scalability is limited by the use of scarce materials, particularly iridium. Iridium oxide, the preferred anode catalyst in PEMEL, offers exceptional stability but is produced only as a by-product of platinum mining, with annual output around 7.5 tons. This study estimates future iridium demand for PEMEL under various deployment scenarios and technological advances. Results show that meeting net zero targets will require both significant improvements in catalyst efficiency and access to roughly 30\% of global iridium production annually. Supply shortages could arise as early as 2030, earlier than previously anticipated. The analysis also reveals that long-term iridium needs beyond 2040 are significantly underestimated. These findings underscore the urgent need for innovation in material efficiency and recycling, and the importance of integrating resource constraints into energy policy and technology planning to ensure a sustainable hydrogen transition. |

| Abstract: | This paper analyzes the impact of disclosures of sustainable investment targets under the EU Sustainable Finance Disclosure Regulation (SFDR) on mutual fund flows. Using a staggered difference-in-differences setup and focusing on retail-oriented index funds, we find that sustainable investment targets have a temporarily positive impact on fund flows in comparison to funds without sustainable investment targets. Furthermore, we find a negative linear relationship between sustainable investment targets and fund flows. While lower targets attract higher fund inflows, higher targets result in significantly lower or even no inflows. Our results suggest that up to a target level of 20% in sustainable investments, index funds can attract more inflows. This suggests a trade-off between sustainability commitments and performance considerations. |

| Abstract: | How does the climatic experience of previous generations affect today's attention to environmental questions? Using self-reported beliefs and environmental themes in folklore, we show empirically that the realized intensity of deviations from typical climate conditions in ancestral generations influences how much descendants care about the environment. The effect exhibits a U-shape where more stable and more unstable ancestral climates lead to higher attention today, with a dip for intermediate realizations. We propose a theoretical framework where the value of costly attention to environmental conditions depends on the perceived stability of the environment, prior beliefs about which are shaped through cultural transmission by the experience of ethnic ancestors. The U-shape is rationalized by a double purpose of learning about the environment: optimal utilization of typical conditions and protection against extreme events. |

| Abstract: | This study examines how the literature addresses the sustainability performance of agricultural cooperatives through four key dimensions: economic and financial, environmental, social and governance. As key entities within the social economy, agricultural cooperatives play a crucial role in advancing sustainable development goals due to their community‐oriented structure, democratic governance based on the user–owner principle and strong territorial ties. We systematically review 274 articles published between 1991 and 2024 that address at least one dimension of the sustainability performance of agricultural cooperatives. Our thematic analysis reveals a significant increase in published studies since 2018, covering a wide range of countries and agricultural products. While the literature predominantly focuses on the economic and financial dimension—either alone or in combination with other dimensions—the environmental, governance and social dimensions are significantly underrepresented, especially in Europe and North America, and in specific sectors such as wine production. In addition, many studies lack a solid theoretical foundation. Overall, the sustainability performance of agricultural cooperatives remains a complex and evolving issue, and this study highlights avenues for future research to improve knowledge and practice. |

| Abstract: | This paper examines the economic and environmental impacts of the European Carbon Border Adjustment Mechanism (CBAM). We develop a multi-country, multi-sector general equilibrium model with input-output linkages and characterise the general equilibrium response of trade flows, welfare and emissions. As far as we know, this is the first quantitative trade model that jointly endogenises the Emission Trading Scheme (ETS) allowances and CBAM prices. We find that the CBAM increases by 0.005\% the EU Gross National Expenditure (GNE), while trade shifts towards domestic cleaner production. Notably, emissions embodied in EU imports fall by 3\%, which is the result of a direct effect (-4.8\%) and a supply chain's upstream substitution effect (+1.8\%). The latter is a dampening effect that we can detect only by explicitly incorporating the production network. In contrast, extra-EU countries experience a slight decline in GNE (0.009\%) and emissions (0.11\%). |

| Abstract: | The introduction of the European Union carbon border adjustment mechanism (CBAM) creates an important incentive for other countries to adopt carbon pricing. The authors examine this policy spillover effect, finding that countries throughout the world have increased their use of carbon pricing regimes as well as their interest in both carbon pricing and decarbonization, especially in the period since the EU focused on this policy tool. If more countries, including the United States, consider border adjustment regimes, this can strengthen such policy spillover effects. However, care should be taken to address the needs of lower-income economies and to avoid disguised protectionism. |

| Abstract: | With the Inflation Reduction Act in the United States and the carbon border adjustment mechanism established by the European Union, ambitious yet contentious climate policies have been passed on both sides of the Atlantic in recent years. Each of these policies has spurred the other to consider not only the impact of these policies themselves, but whether the policies can serve as inspiration for further policy innovation. As new administrations are set to enter office on both sides of the Atlantic, and as the geopolitical landscape is getting more complicated, we examine the implications of the recent landmark policies in the United States and European Union for the evolution of climate policy over the next decade. We also reexamine the received wisdom on effective design for effective climate policy mix that targets net-zero emissions goals. |

| Abstract: | Diverting waste away from and zero waste to landfills are key sustainability policy aims of local and national governments around the world, particularly in countries with large waste footprints from rapid consumption growth and urbanisation. Segregation at the source of waste generation can offer a low-cost solution to urban waste footprints, yet segregation rates are low in many places, especially in the cities of developing economies. This paper studies a staggered randomised intervention offering training and education to citizens about waste segregation. Citizens in the city of Patna in India were given training on waste segregation at source, recycling and its environmental benefits in a large experimental intervention undertaken in collaboration with the city administration. Segregation-at-source increased substantially among households that received the intervention, and additional boosts to segregation arose from spatial spillovers, as the programme delivered at least a double-digit benefit-cost ratio. Citizen training, when effectively designed and implemented, does deliver a low-cost solution for the cities of developing countries to both reduce their waste footprint and enhance local environmental sustainability. |

| Abstract: | Climate change exhibits substantial variability across both space and time, requiring mitigation and adaptation strategies that effectively address challenges at global and local scales. Accurately capturing this variability is essential for assessing climate impacts, attributing underlying causes, and formulating effective policies. This study introduces simple yet robust quantitative methods to detect local warming, distinguish among different types of warming, and compare warming trends across contiguous U.S. states using the concept of warming dominance. In contrast to traditional approaches that focus solely on average temperatures, our analysis rigorously and systematically examines the entire distribution of daily temperatures for the contiguous United States from 1950 to 2021. The results reveal that, while 44% of states show no statistically significant warming based on average temperature trends, a much larger proportion—84%—exhibit warming when assessing various quantiles of the distribution. These findings underscore the substantial heterogeneity in warming patterns: some states, such as those located in the so-called “Warming Hole, ” display no evidence of warming at any quantile; others experience more pronounced warming in either the lower or upper tails of the temperature distribution; and a few states show consistent warming across all quantiles. The study concludes by identifying which states exhibit warming dominance over others and which appear comparatively less affected. These insights are particularly important in the United States, where climate policy is formulated and implemented at both federal and state levels. |

| Abstract: | Carbon border adjustments (CBAs) are fees imposed on the imports of commodities and products based on the quantity of greenhouse gases (GHGs) emitted during their production. The purpose of a CBA is to allow the producers of such commodities in countries with highly ambitious climate goals to remain competitive in their domestic markets against imports from less regulated jurisdictions. CBAs are not part of the current climate and international trade policy mix, but that will change in October when the European Union’s Carbon Border Adjustment Mechanism (CBAM) goes into effect. Moreover, multiple bills in the US Senate propose CBAs. The purpose of this report is to identify some of the important CBA design elements and discuss options available to policymakers, particularly in the European Union and the United States. |

| Abstract: | This article discusses the idea of a judicial accountability gap in the obligations of EU central banks in relation to climate change policy. With the interest in incorporating climate change considerations into monetary policy on the rise, legal scholarship has focussed largely on the toolbox at the disposal and the political accountability of central bankers with respect to the sustainability transition. The judicial route has so far remained largely unexplored, the general global trend of climate litigation notwithstanding. In light of this omission, we develop a framework to address the judicial accountability gap in three steps. First, we explain the implications of the special status of climate change mitigation objectives in the EU constitutional order on members of the European System of Central Banks (ESCB). Then, we explain how these treaty obligations apply not only to the Eurosystem, which has been well explored in the literature, but also to non-euro area Member States. This point is particularly underexplored, despite its significant implications for the success of the EU’s sustainable finance agenda, which is contingent on a supportive macrofinancial regime. Finally, we discuss different judicial accountability routes to ensuring that central banks adequately incorporate the secondary mandate objectives in their policies. We examine whether establishing a “minimum standard” for meeting treaty obligations on incorporating climate change considerations into central bank policies could lead to the conceptualisation of a standard of judicial review across the EU, thereby enhancing the democratic legitimacy of central banks within the EU’s economic constitution. |

| Abstract: | Although the environmental impact of trade has been a long-standing concern, there is still only scant evidence on the channels through which international market access affects pollution. In this paper, we exploit the unique episode of China’s world market integration in the early 2000s to provide direct empirical evidence on three such mechanisms. We combine granular satellite data on air pollution with detailed information on manufacturing firms and coal power plants, and leverage exogenous foreign demand shocks for identification. Three main findings emerge: exporting firms reduce local pollution (scope-1); pollution levels around coal power plants rise due to regional export shocks (scope-2); and upstream suppliers reduce pollution in the face of export demand shocks to downstream firms (scope-3). Our findings point to China’s reliance on coal power plants to fuel its export-driven growth as one of the main drivers of the rise in pollution. |

| Abstract: | This report analyzes the differences between risk profiles posed by fossil assets, such as natural gas power generation and gas-powered vehicles, and those of “green” alternatives, such as wind power and electric vehicles. Fossil assets tend to be exposed primarily to uncertainty in operational expenditures (OPEX) such as fuel prices, whereas green assets tend to be exposed primarily to uncertainty in capital expenditures (CAPEX). This report builds a quantitative dynamic economic model of investment under uncertainty that accounts for these different kinds of risk. The results show the relative value of such CAPEX-exposed green assets over OPEX-exposed fossil assets for reducing exposure to future cost uncertainty. The model’s key conclusions are that (1) correlated OPEX risk across assets implies that an all-green portfolio has lower uncertainty than an all-fossil one even when the assets themselves have similar total cost uncertainty, (2) adding a green asset option to an otherwise all-fossil investment strategy typically reduces cost uncertainty by more than adding a fossil option to an all-green strategy does, and (3) actually owning such a green asset almost uniformly reduces cost uncertainty by shielding society (investors and consumers) from OPEX risk. The primary mechanisms driving these results are threefold: first, an investment in CAPEX-exposed assets immediately resolves substantial cost uncertainty, second, spikes in fuel prices increase OPEX for all existing fossil assets whereas spikes in green CAPEX costs only affect new investments, and third, the availability of multiple options for future asset replacement decisions avoids locking in exposure to CAPEX risk. |

| Abstract: | Purpose: The article aims to visualise in a single graph fish and meat processing company groups in Spain with respect to long-term solvency, energy, waste and water intensity and gender employment gap. Design/methodology/approach: The selected financial, environmental and social indicators are ratios, which require specific statistical analysis methods to prevent severe skewness and outliers. We use the compositional data methodology and the principal-component analysis biplot. Findings: Fish-processing companies have more homogeneous financial, environmental and social performance than their meat-processing counterparts. Specific company groups in both sectors can be identified as poor performers in some of the indicators. Firms with higher solvency tend to be less efficient in energy and water use. Two clusters of company groups with similar performances are identified. Research limitations/implications: As of now, few firms publish reports according to the EU Corporate Sustainability Reporting Directive. In future research larger samples will be available. Social Implications: Firm groups can visually see their areas of improvement in their financial, environmental and social performance compared to their competitors in the sector. Originality/value: This is the first time in which visualization tools have combined financial, environmental and social indicators. All individual firms can be visually ordered along all indicators simultaneously. |

| Abstract: | In the mid-1990s, the concept of smart growth emerged in the United States as a critical response to the phenomenon of suburban sprawl. To promote sustainable urban development, it is necessary to further investigate the principles and applications of smart growth. In this paper, we propose a Smart Growth Index (SGI) as a standard for measuring the degree of responsible urban development. Based on this index, we construct a comprehensive 3E evaluation model (covering economic prosperity, social equity, and environmental sustainability) to systematically assess the level of smart growth. For empirical analysis, we selected two medium-sized cities from different continents: Wuhu County, China, and Colima, Mexico. Using an improved entropy method, we evaluated the degree of smart growth in recent years and analyzed the contributions of various policies to sustainable urban development. Guided by the ten principles of smart growth, we further linked theoretical insights to practical challenges and formulated a development plan for both cities. To forecast long-term trends, we employed trend extrapolation based on historical data, enabling the prediction of SGI values for 2020, 2030, and 2050. The results indicate that Wuhu demonstrates greater potential for smart growth compared with Colima. We also simulated a scenario in which the population of both cities increased by 50 percent and re-evaluated the SGI. The analysis suggests that while rapid population growth tends to slow the pace of smart growth, it does not necessarily exert a negative impact on the overall trajectory of sustainable development. Finally, we conducted a study on the application of Transit-Oriented Development (TOD) theory in Wuhu County and proposed several policy recommendations aimed at enhancing the city's sustainable urban development. |

| Abstract: | We began our work on border adjustments nearly a decade ago, because we did not expect that the approach taken in the American Clean Energy and Security Act to provide protection for domestic producers against imports from countries without greenhouse gas (GHG) control policies would be acceptable to the World Trade Organization (WTO). In 2018, together with Georgetown University Law School professors Jennifer A. Hillman and Mathew C. Porterfield, we developed a WTO-compatible Framework Flannery, Brian P., Jennifer A. Hillman, Jan W. Mares, and Matthew C. Porterfield, 2020. Framework Proposal for a US Upstream GHG Tax with WTO-Compliant Border Adjustments: 2020 Update. Washington, DC: Resources for the Future. for border adjustments in the context of a US domestic carbon tax. As a central concept of the Framework, we proposed a Greenhouse Gas Index (GGI) to account for the carbon dioxide equivalent emissions (CO2e) required to manufacture covered GHG-intensive products. For a given manufacturing facility or operation, e.g., to produce steel or petrochemicals, GGI accounts for GHG emissions occurring both from production operations, as well as the emissions required to produce GHG-intensive products purchased from suppliers of electricity, fuels used to generate thermal energy and raw materials. For many years, US facilities that emit more than 25, 000 tonnes CO2e annually have determined and reported their GHG emissions to EPA. Key innovations in the Framework include the treatment of emissions from products acquired through the manufacturer’s supply chain (in a fashion similar to value-added taxes) and the design of straightforward procedures to allocate emissions from a facility to the GHG-intensive products it manufactures. Our approach, GGI, is consistent with standards developed by the International Organization for Standardization (ISO). In a consistent, comprehensive fashion, GGI applies to GHG-intensive products in all sectors of the economy, including those that produce aluminum, iron, and steel. The appendix to this report contains a list with links to our blogs and reports on border adjustments and the GHG intensity of products.Over the past several years, we have interacted with experts from academia, national governments, international organizations, and importantly, with over a dozen sectoral trade associations. Based on these interactions, discussions, and our own relevant experience, we believe that our approach is feasible for industry and relevant to various applications that involve GHG-intensive products, including, for example, border adjustments, procurement policies, and corporate reporting. In particular, GGI could apply to products of US and foreign manufacturers in the aluminum, iron, and steel sectors.This report updates, expands upon, and should be considered as a replacement for the testimony and submissions we provided the US International Trade Commission related to its hearing on December 7, 2023. It additionally serves as a modification and expansion of the modules for Iron, Steel, and Ferroalloys and for Alumina and Primary and Secondary Unwrought Aluminum in our 2022 report: The Greenhouse Gas Index for Products in 39 Industrial Sectors.We are currently developing and will publish the estimated range of GGIs for many products in the modules for 39 industrial sectors in our 2022 report because of the US ITC hearing and anticipating further government interest in this subject.The tables below provide estimated, illustrative low and high GGI values for representative basic products in the aluminum and steel sectors. Results are illustrative because manufacturers in the United States and around the globe utilize an enormous variety of processes, sources of energy, and raw materials in facilities with differing efficiencies to create similar products. |

| Abstract: | This study examines the impact of Conference of the Parties (COP) summits on innovation using an event study framework. Innovation is measured by patent grants, distinguishing between the total number of patents and the number of patents in environmental technologies, based on the World Intellectual Property Organization classification. We find that hosting a COP summit leads to a significant and lasting increase in the total number of patent grants, with an average rise of about 35 percent per year from the seventh to the thirteenth year after the summit, but has only a limited effect on the number of patent grants in environmental technologies. We further examine potential heterogeneity in the effects of COP summits by analyzing the impact of hosting a summit on patents in environmental technology compared to other technologies separately for each host country. The results suggest that while hosting a COP summit generally promotes environmental patenting, the effect is negative in some countries. We discuss possible reasons, including diminishing returns in green innovation and the influence of large industrial emitters. The findings are robust across alternative estimators, the inclusion of control variables, and different measures of patenting activity. |

| Abstract: | Carbon pricing is increasingly seen as a crucial tool in the global effort to combat climate change. In this evolving policy landscape, Taiwan is actively advancing the development of its national carbon fee, which was launched in 2024, with an initial focus on the electricity and manufacturing industries. Within this framework, it is exploring the adoption of measures aimed at safeguarding its industries from potential adverse consequences. Opposition to carbon pricing instruments is likely to arise from both the industrial sectors and population groups that will be impacted the most. This report focuses on resistance from the industrial sector and examines the relevant measures that have been adopted by major carbon pricing jurisdictions, including in the European Union, Singapore and UK, to provide insights for addressing potential industry resistance and the development of tailored recommendations for Taiwan. |

| Abstract: | How does uninsurable idiosyncratic risk shape the optimal design of carbon taxation? To answer this question, I augment a heterogeneous-agent incomplete-markets model with a climate externality on total factor productivity and dirty energy demand of households and firms. A government sets a carbon tax on energy and redistributes its revenue via lump-sum transfers. When labor tax instruments are held fixed, I find that the optimal carbon tax rises with the level of uninsurable idiosyncratic risk. In contrast, when labor taxes can adjust, the carbon tax remains relatively stable across different economic environments. Overall, welfare gains are primarily driven by improved insurance provision. |

| Abstract: | Achieving the ambitious decarbonization goals established by the Biden administration, 100 percent clean electricity by 2035 and a net-zero emissions economy by 2050, requires substantially increasing the share of clean and renewable energy resources in the electricity generation mix. To reach these decarbonization targets cost-effectively, renewable power will need to grow to multiples of current levels. The transmission system is not equipped to handle the anticipated substantial increase in power flows; its lack of capacity and availability leads to grid congestion, which causes higher energy prices and curtails renewables. Moreover, with the anticipated electrification of the economy leading to large increases in future demand, the burden on the power grid is ever increasing. A report from the REPEAT project estimates that to take full advantage of the subsidies offered in the Inflation Reduction Act (IRA), transmission capacity must grow by about 2.3 percent per year, more than double the rate of the past 10 years (Jenkins et al. 2022).Nevertheless, getting new projects built can take over a decade due to the complexities involved in their planning, siting, and permitting. State and federal policymakers have acknowledged this challenge and taken steps to support the buildout of new transmission. The Infrastructure Investment and Jobs Act (IIJA) and IRA carved out support for transmission expansion, allocating $12.5 billion and $5 billion, respectively. Furthermore, the Biden administration recently announced plans to streamline the federal permitting process for transmission lines through the Department of Energy (DOE) to facilitate buildout. Nonetheless, experts are still skeptical that we can build enough new transmission in time to support the shifting generation mix and increasing electrification to meet climate targets.However, building new lines is not the only way to bolster resilience, reliability, and affordability. Several different types of investments can deliver similar outcomes. Grid-enhancing technologies can increase the capacity of existing lines, distributed energy resources can spread out generation resources so they are closer to load centers, and microgrids can use on-site power generation to support pockets of load and insulate campuses or communities from issues on the broader grid. These solutions can deliver benefits, but each is best suited to a specific set of circumstances and faces its own technical and regulatory barriers to implementation.This report surveys the literature on different types of grid solutions. We discuss how the technologies work, in what circumstances they may act as substitutes for transmission expansion, evidence of their impact, and challenges (both technical and regulatory) in implementing them. New lines will undoubtedly be an important piece of the energy transition, but exploring these additional types of investments can help us understand where and when lower-cost and more rapidly deployed alternatives can provide solutions to some of our transmission woes. |

| Abstract: | Populist parties increasingly deploy narratives of social injustice to portray climate policy as elitist and unfair. This paper investigates how such narratives affect public attitudes toward populism and democratic institutions. We conduct a survey experiment with approximately 1, 600 respondents in Germany, exposing participants to three common narratives about the distributional costs of climate policy. Our findings show that the narrative emphasizing disproportionate burdens on low-income households significantly increases climate-populist attitudes and reduces satisfaction with democracy. These effects are particularly pronounced among low-income, East German, and conservative voters. By contrast, the narrative that companies can circumvent the cost of climate action fosters climate populism among left-leaning individuals. The results suggest that the framing of how the costs of climate policy are distributed strongly shapes its political acceptance and vulnerability to populist mobilization. |

| Abstract: | This paper examines the relationship between land ownership concentration and the likelihood of hosting large green energy facilities, specifically mega-photovoltaic (PV) plants, defined as those exceeding 50 hectares. Focusing on Spain, we find that municipalities with a higher proportion of agricultural land concentrated in large farms are significantly more likely to accommodate mega PV plants. This effect remains robust after accounting for key factors influencing PV deployment, including terrain ruggedness, solar potential, and proximity to transmission lines and urban centers. To further neutralize unobserved factors that jointly influence land concentration and PV plant location, we leverage cadastral (parcel) data to conduct an intra-municipal analysis at the 0.5×0.5 km grid-cell level. Our findings reveal that grid cells with larger cadastral parcels have a substantially higher probability of being part of a mega PV facility. A simple theoretical model explains this pattern by highlighting the coordination challenges faced by small landowners. Unlike large ones, fragmented landholders struggle to meet developers’ land requirements, which are necessary to cover fixed project costs. Consistent with this mechanism, we also show that areas with irrigated agriculture are less likely to host mega PV plants and exhibit more unequal distributions of plant locations by land size. Finally, we provide external validity by confirming a similar positive association between mega PV plants and land concentration across U.S. counties. These findings underscore the implications of land inequality for the spatial distribution of renewable energy projects, shedding light on the limited local benefits of such investments and the growing opposition from rural communities. |

| Abstract: | This working paper quantifies the role of current land quality and geographic conditions as well as projected future climate change for agricultural productivity differences across and within Latin American and Caribbean (LAC) countries. It combines geospatial data on potential yields by crop and grid-cell, with a spatial accounting framework. If LAC countries produced their crops in the locations, they produce them with potential yields rather than actual, the 18 percent aggregate yield deficit relative to the richest countries would be reversed to an 18 percent surplus. While there are considerable cross-country and within-country heterogeneity, overall LAC countries have favorable natural land productivity. With improved input application and cultivation practices most LAC countries can double agricultural productivity, with substantial structural change implications. Climate change will reduce average yields in most LAC countries, but because of its heterogeneous effects across regions, there is more scope for yield gains from the spatial reallocation of production than under current conditions. |

| Abstract: | In order to investigate strategic interactions between a "global north" and a "global south" we introduce a two-country extension of the model in Golosov et al. (2014). We consider different transfers between the two regions, including transfers that can improve the abatement technology. Our model can accommodate several kinds of heterogeneity, including in preferences, time discount rates, and damages resulting from the stock of accumulated GHG. We solve for both planner’s solutions and non-cooperative equilibria. We then calibrate our model in order to study quantitative differences between these solutions and to quantitatively explore the role of heterogeneity and Knightian uncertainty. We characterize emissions, damages, consumption, transfers, and welfare by computing the Nash equilibria of the associated dynamic game. We then compare these to efficiency benchmarks. Further, we investigate how (deep) uncertainty affects climate outcomes. We develop a general model for the study of optimal control and differential games that are linear-in-state, which we term the Integral Transformation Method (ITM), which encompasses several existing models as special cases. |

| Abstract: | The primary aspiration of this paper is to learn about the effects of agricultural energyconsumption, agriculture value added, agricultural land and fertiliser consumption on environmentalpollution in Visegrad countries. The research employs panel data from long-run models FMOLSand DOLS, covering the period from 1995 to 2020. The study suggests that there is a positive andstatistically significant correlation between CO2 emissions from agriculture in Central and EasternEuropean countries, and factors such as higher energy consumption, increased value from agriculturalproduction, greater fertiliser consumption, and larger arable land areas. The FMOLS and DOLSmodels’ long-term coefficients suggest that energy consumption in agriculture and crop area are themain factors contributing to the increase in CO2 emissions from agriculture in the studied countries.The study recommends a sustainable energy transformation of agriculture by limiting the use of fossilfuels in agricultural production and reducing share of arable land. |

| Abstract: | We estimate the impact of environmental law enforcement on violence in the Brazilian Amazon. The introduction of the Real-Time Deforestation Detection System (DETER), which enabled the government to monitor deforestation in real time and issue fines for illegal clearing, significantly reduced homicides in the region. To identify causal effects, we exploit exogenous variation in satellite monitoring generated by cloud cover as an instrument for enforcement intensity. Our estimates imply that the expansion of state presence through DETER prevented approximately 1, 477 homicides per year, a 15% reduction in homicides. These results show that curbing deforestation produces important social co-benefits, strengthening state presence and reducing violence in regions marked by institutional fragility and resource conflict. |

| Abstract: | We study the problem of designing and hedging unit-linked life policies whose benefits depend on an investment fund that incorporates environmental criteria in its selection process. Offering these products poses two key challenges: constructing a green investment fund and developing a hedging strategy for policies written on that fund. We address these two problems separately. First, we design a portfolio selection rule driven by firms' carbon intensity that endogenously selects assets and avoids ad hoc pre-screens based on ESG scores. The effectiveness of our new portfolio selection method is tested using real market data. Second, we adopt the perspective of an insurance company issuing unit-linked policies written on this fund. Such contracts are exposed to market, carbon, and mortality risk, which the insurer seeks to hedge. Due to market incompleteness, we address the hedging problem via a quadratic approach aimed at minimizing the tracking error. We also make a numerical analysis to assess the performance of the hedging strategy. For our simulation study, we use an efficient weak second-order scheme that allows for variance reduction. |

| Abstract: | The central instruments of a cap-and-trade program are its abatement schedule and a system of guardrails designed to prevent permit prices from becoming excessively high or low. I argue that these instruments are currently poorly aligned in the EU’s cap-and-trade flagship climate policy, the EU ETS. I argue that the abatement schedule risks being overly ambitious and that the ETS’ existing guardrails, the Market Stability Reserve (MSR), do not offer sufficient protection against extreme prices. This misalignment may result in substantial economic costs and could ultimately undermine public support for the ETS. This paper recommends consideration of more effective guardrails, such as the well-established the price collar as implemented in California’s cap-and-trade program. |

| Abstract: | Die verstärkte Nutzung von Holz als nachhaltigen Baustoff bietet ein erhebliches Potenzial zur Reduktion der CO₂-Emissionen im Bauwesen. Gleichzeitig stellt die natürliche Variabilität von Holzprodukten, insbesondere deren flüchtige organische Verbindungen (VOCs), eine Herausforderung für die Raumluftqualität dar. Monoterpene wie »-Pinen und 3-Caren dominieren die Emissionen von Kiefernholz und stehen im Fokus aktueller Forschung zur Bewertung und Reduktion von VOC-Emissionen und -Expositionen. Die standardisierte Vorgehensweise zur Analyse von Emissionen, die auf der Prüfkammermethode gemäß DIN EN 16516:2017 basiert, ist zeitaufwändig. In vorliegenden Projektbericht wird dargestellt, dass die Nahinfrarot-Spektroskopie (NIR) in Verbindung mit multivariaten Analysemethoden eine effiziente und präzise Alternative bieten kann. Die Ergebnisse zeigen, dass mit der NIR-Technologie zuverlässige Vorhersagemodelle für Terpenemissionen aus Kiefernholz erstellt werden konnten. Für »-Pinen und 3-Caren wurden dabei kreuzvalidierte Korrelationskoeffizienten von R²CV = 0, 77 erzielt, was auf eine gute Modellgüte hinweist. Die mittlere Abweichung der Kreuzvalidierung (RMSECV) betrug 1.257 μg/m³ für »-Pinen und 1.232 μg/m³ für 3-Caren. Diese Modelle ermöglichen eine schnelle Bewertung der Produktemissionen, wobei die Modellgenauigkeit insbesondere bei mittleren und höheren Konzentrationen überzeugt. Einschränkungen bestehen jedoch in niedrigen Konzentrationsbereichen, was die Anwendung der Methode in solchen Fällen begrenzt. Die Anwendbarkeit auf Holz-Materialien wie Strands (lange, schlanke Späne), die zur Herstellung von OSB verwendet werden, zeigte sich aufgrund von Transmissionseffekten und der hohen spektralen Variabilität als problematisch. Um die Technologie für Holzwerkstoffe nutzbar zu machen, sind weiterentwickelte Kalibrationsansätze erforderlich. Insgesamt stellt die NIR-Technologie eine vielversprechende Ergänzung zu bestehenden Analysemethoden dar und eröffnet neue Perspektiven für die nachhaltige Verarbeitung von Holzprodukten... |
| Abstract: | The increased use of wood as a sustainable building material offers significant potential for reducing CO₂ emissions in the construction sector. At the same time, the natural variability of wood products, particularly their volatile organic compounds (VOCs), poses challenges for indoor air quality. Monoterpenes such as »-pinene and 3-carene dominate the emissions of pine wood and are the focus of current research aimed at assessing and reducing VOC emissions and exposure. The standardized approach to emission analysis, based on the chamber method according to DIN EN 16516:2017, is time-consuming. This project report demonstrates that near-infrared spectroscopy (NIR), combined with multivariate analytical methods, can provide an efficient and precise alternative. The results show that reliable predictive models for terpene emissions from pine wood could be developed using NIR technology. For »-pinene and 3-carene, cross-validated correlation coefficients of R²CV = 0.77 were achieved, indicating good model quality. The mean deviation in cross-validation (RMSECV) was 1, 257 μg/m³ for »-pinene and 1, 232 μg/m³ for 3-carene. These models enable a rapid evaluation of product emissions, with model accuracy performing particularly well at medium and higher concentrations. However, limitations exist in the lower concentration range, which restricts the applicability of the method in such cases. The applicability to wood materials such as strands (long, thin chips) used for the production of OSB, proved problematic due to transmission effects and high spectral variability. To make the technology usable for woodbased materials, advanced calibration approaches are required.Overall, NIR technology represents a promising complement to existing analytical methods and opens up new perspectives for the sustainable processing of wood products... |

| Abstract: | Over the past decade, wildfires have become more frequent and damaging in the western United States, leading to unprecedented financial losses and significant challenges for the insurance market in affected areas, especially in California. Several major insurers have stopped writing policies for new clients in California, at least temporarily. Homeowners in high-risk areas face soaring insurance premiums and increasing insurer-initiated nonrenewals.In this report, we look at the long experience of insuring flood losses in the United States to find solutions to address the insurability of wildfires. The federal government created the government-backed National Flood Insurance Program (NFIP) in 1968, and since then, the NFIP has provided almost all flood loss coverage. Over time, this single-peril program has faced numerous challenges, including difficulty maintaining widespread participation, financial instability, inadequate pricing with respect to risk, and problems related to flood risk mapping and communication. Floods and wildfires each present insurers with correlated risks that have grown over time as a result of climate change and increasing development in hazardous areas. Because of these similarities, an analysis of the NFIP’s experience with insuring flood risk can offer insights for policy directions to address the rising challenges of insuring wildfires.Lessons from the NFIPLesson 1: Most People Do Not Voluntarily Buy Disaster InsuranceEvidence from flood insurance suggests that stand-alone disaster insurance policies have low uptake rates unless mandated. The federal government mandates that owners of homes within Special Flood Hazard Areas (SFHAs), defined based on 100-year floodplains, have flood insurance if they have federally backed mortgages. However, overall take-up of flood insurance is low. This provides a cautionary tale for wildfire insurance. Currently, wildfire insurance is bundled in standard homeowner’s insurance policies required by mortgage lenders. If wildfire coverage were to become a stand-alone product or the requirement were to change, there is a risk that take-up will be low, leaving more households exposed to the full financial ramifications of wildfire damages.Lesson 2: When Insurance Premiums Do Not Reflect Risks, There Will Be Insurer Solvency Problems and Greater Exposure to RiskInsurance pricing needs to accurately reflect risks, both to support insurer solvency and to send price signals to homeowners about where to live and how much to invest in hazard mitigation. Over time, underpricing of risk by the NFIP has led the program to incur substantial debt to the US Treasury and caused increased development in high-hazard flood areas. Underpricing of wildfire risks in high-hazard areas—resulting from a combination of regulation, climate change, and uncertainty among insurers about the true level of risks—is likely also contributing to current insurability problems. Catastrophe models, which have recently been integrated into the NFIP through Risk Rating 2.0, offer a potential path forward.Lesson 3: Risk-Based Pricing Will Present Some Affordability ChallengesRisk-based pricing, while necessary for insurer solvency, can result in premiums that are unaffordable for low- and moderate-income households—especially in places facing rapid increases in risk. Means-tested subsidies and public financial backstops are options to address affordability while maintaining insurer solvency. However, there is an inherent tension between addressing affordability concerns and maintaining risk-based price signals. Innovative insurance products like community-based insurance or parametric microinsurance offer potential alternatives, but these approaches have not yet been successfully implemented in the United States.Lesson 4: Risk Communication Is Essential but Hard to Do WellAccurate risk communication is critical for informed decisionmaking. Maps of SFHAs, used in the NFIP to delineate where zoning, building code, and insurance requirements apply, often lead to the misconception that outside these zones, risk is minimal. Communicating wildfire risks, which is often done through broad risk categories, may face similar challenges. Recently, FEMA and others have begun to improve access to more graduated, high-resolution flood risk data, and there is some evidence that this information has affected home buyers’ search behavior. Evidence from both the flood and fire contexts also suggests that mandatory hazard disclosure can affect buyers’ valuations of risky properties, though such rules can face political pushback because of concerns over property values.Lesson 5: Investments in Risk Mitigation Are Critical but Costly and DifficultRisk reduction measures lower the cost of insuring disasters and thus provide an important strategy for simultaneously addressing both affordability and solvency concerns. While NFIP premium reductions have incentivized some community-led investments in flood risk reduction, flood adaptation investments are often expensive, and most adaptation investments are heavily dependent on federal funding. More low-cost hazard mitigation options are available for wildfire than for floods, but incentivizing these activities through insurance premium reductions requires coordination across insurers and with fire service professionals and communities. These activities must also be coordinated among homeowners and forest landowners, including the federal government.Policy DirectionsImproving Insurance AvailabilityTo promote insurance availability, premiums should be adequate for covering claims, including those due to catastrophic events. Adopting catastrophe models for wildfire risk assessment, with oversight similar to Florida’s approach for regulating use of hurricane catastrophe models, can support risk-based pricing and help maintain insurer solvency. These models can help ensure fair pricing and accurate signaling of risk by minimizing cross-subsidization of policyholders in high-risk areas by those in low-risk areas.Addressing AffordabilityThree options for maintaining affordability are means-tested programs for premium discounts or subsidies, a public financial backstop, and new insurance products tailored to low- and moderate-income community needs, such as community-based insurance and parametric microinsurance. However, along with their effects on affordability, policymakers need to consider effects of such policies on cross-subsidization and incentives for risk mitigation.Motivating Risk ReductionSeveral strategies are available to federal, state, and local policymakers to reduce the three components of risk: exposure, vulnerability, and hazard. Risk communication policies and disclosure laws can help inform household decisionmaking. Local land use policies can help reduce community-level exposure to risk. Building codes can be effective in reducing structural vulnerabilities. Finally, vegetation management—at both the individual and community scales—can help reduce hazard. Policy can play a key role in motivating risk reduction activities and deepening coordination among various stakeholders, including insurers. |

| Abstract: | Rice is a staple crop in India, traditionally cultivated using the Transplanted Puddled Rice (TPR) method. This traditional method, while effective and very popular amongst farmers, is highly labour, water, and energy-intensive, that leads to significant groundwater depletion and higher energy usage in pumping groundwater. In response to these challenges, the Direct Seeded Rice (DSR) method has been introduced as a more sustainable alternative. DSR involves sowing seeds directly into the field, eliminating the need for growing and transplanting seedlings. This method, tested in various field trials, promises to have several benefits, including water savings, reduced labour and production costs, higher economic returns, and lower methane emissions. However, the success in farmer fields when adopted at scale outside trials remains to be analysed critically. In that context, this study was commissioned through a MoU with National Project Management Unit (NPMU), Atal Bhujal Yojana (ABY). ABY, also known as Atal Jal, is a central sector scheme aimed at sustainable groundwater management with community participation. Launched in December 2019, ABY focuses on improving groundwater management in water-stressed areas across seven states, including Haryana. The adoption of DSR in Haryana has been gradual but promising. The area under rice cultivation in the state has increased significantly over the years, with initial efforts to introduce DSR beginning around 2009. The state government has played a crucial role in promoting DSR by offering financial incentives to farmers. In 2022, an incentive of INR 4000 per acre1 was introduced to encourage farmers to adopt DSR. Given its uptake in Haryana, the objective of this study is to assess the socio-economic and environmental benefits of DSR, identify the challenges, and offer recommendations for scaling up this technology in Haryana and other regions. The study employed a multi-faceted approach including qualitative surveys with stakeholders, focus group discussions, field visits, and a large-scale quantitative survey (sample size is 809) of DSR and TPR farmers across selected districts in Haryana to assess the impact of DSR. These farmer-level sources were complemented by water flow meter data analysis and remote sensing analysis. |

| Abstract: | This study examines the causal impact of PM2.5 air pollution exposure on premature mortality in Southern European cities from 2010 to 2018. To address endogeneity, we leverage local variations in rainfall as a source of random variation in PM2.5 exposure. Using the Two-Sample Two-Stage Least Squares (TS2SLS) estimator to reconcile monitoring station-level and city-level data, our findings reveal a statistically significant increase in premature mortality caused by PM2.5. According to our preferred specification, a 1% increase in PM2.5 causes a 1.13% rise in the under-65 mortality rate and a 1.41% rise in the infant mortality rate. The results are robust to alternative specifications. The most affected populations are those residing in urban areas (relative to suburban areas) and individuals living in cities located in richer regions (as opposed to poorer ones). |

| Abstract: | The European Union (EU) is strongly committed to steering its economy away from high-carbon and pollution-intensive production and toward climate-neutral technologies and business models by 2050. If this transition is not accompanied by adjustment assistance, however, making deep reductions in greenhouse gas (GHG) emissions could disproportionately burden certain segments of society that are dependent on producing or using carbon-intensive energy resources as a primary employer or mainstay of the economy (Vona 2021). Many regional economies in Europe rely on fossil fuel extraction (oil, coal, or gas) or energy- and carbon-intensive production (e.g., steel production and electricity generation). As European Commission president Ursula von der Leyen has frequently stated, the large-scale deployment of low-carbon energy can succeed only if conducted in a fair and inclusive way for all European citizens (European Commission 2019k), what many refer to as just transition.The aim of this report is to distill important lessons learned from the EU experience in promoting just transition to help US policymakers identify key components of a comprehensive and effective energy transition policy package. The report examines EU-level programs implemented over the period 2014–20 and summarizes the policy changes proposed in the European Green Deal for 2020–25.The just transition concept originated in the US labor movement during the 1970s to describe the need for a support system for workers unemployed because of environmental protection policies (Henry et al. 2020). In the EU, the quality of work and life of its citizens has been a policy goal since its founding. One of the guiding principles of European policymaking is a commitment to reduce social, economic, and territorial development disparities among EU regions to promote integration and the economic growth of all member states. This is referred to as cohesion policy, which is enshrined in the Treaty on the Functioning of the European Union (Art. 174) and plays a crucial role in setting political priorities at the EU level (European Commission 2022g). Cohesion policy is the term used in the EU context to refer to regional policy. In the EU, socioeconomic development is promoted as an expression of solidarity between the EU member states and their regions. Programs and funding targeting socioeconomic development aim to remove economic, social, and territorial disparities across the EU, supporting the restructuring of declining industrial areas and diversification of declining rural areas. The rationale for cohesion policy is to mitigate the negative side effects from the creation of a single market and ensure that all EU citizens can reap the benefits (Samecki 2009). These policies and programs have been used as building blocks to shape EU just transition policy over time, including in the European Green Deal. For discussion of the evolving interpretation of just transition, see ILO (2015); Stevis and Felli (2015); Verdolini (2023).It is important to note that most of the EU programs we discuss are ultimately implemented and used by the member states, which have a fair degree of autonomy in selecting the projects to be funded within the broader design principles set up at the EU level. Other reports in this series have reviewed some of the ways these EU-level programs have been implemented in specific countries. Reports on just transition measures related to reductions in the coal sector in Germany, Poland, and the UK can be found on the RFF website at https://www.rff.org/publications/all-publications/?offset=12&topic=10098. The report on “Just Transition in Poland” examines the topic in the broader context of economic restructuring and increased regional integration of the country.Within the EU, the concept of just transition indicates the need to support and help territories and regions most affected by the transition to a climate-neutral economy, prioritizing those that have less capacity to deal with the costs of transition (European Commission 2019b). The EU currently distinguishes between regions dependent on extraction of coal and fossil fuels and those dependent on carbon-intensive industries (Alves Dias et al. 2021).This report does not present an exhaustive list of all programs and investments at the EU level that have been used to support workers and communities; rather, it identifies the key relevant EU policies and programs, describes their main features, and gives several examples of specific funded projects and activities. Many of these policies and programs have been motivated by other energy and economic issues, such as improving energy efficiency for energy security and enhanced productivity, but they include tools that are also applicable to just transition in the context of decarbonization.Sections 2 and 3 of this report focus on the policies and programs during the full EU long-term budget cycle from 2014 to 2020. Section 4 then discusses more recent EU policy priorities and programs, some of which are still being shaped under the European Green Deal. The report thus provides a broad picture of how the debate around just transition is reshaping and adjusting EU policies and programs. Section 5 concludes by summarizing the relevant lessons learned from the EU experience.The review of EU just transition policies provides several relevant insights for policymakers seeking to address equity and fairness issues in the United States’ energy transition. See Look et al. (2021) for a review of key issues for the US energy transition. We briefly summarize the key points here, with discussion of them in Section 5.The multiannual and investment-focused EU budget provides long-term, stable funding, which supports addressing many of the challenges associated with just transition.The EU Just Transition Mechanism aims to mobilize substantial public and private investment between 2021 and 2027 to support just transition efforts in Europe.The Just Transition Mechanism includes a Just Transition Platform to serve as a single access point for related EU-wide resources and a centralized source for technical assistance. The Biden administration has established a similar resource.The EU just transition policy framework requires EU member states to develop Territorial Just Transition Plans before accessing funds. The Biden administration has established a mechanism for rapid response teams to support local transition planning.One of the three pillars of EU just transition policy in the Green Deal is access to the Public Sector Loan Facility to support the implementation of just transition projects. The United States does not have a financing program explicitly dedicated to supporting transition in energy communities, although the creation of the Greenhouse Gas Reduction Fund in the Inflation Reduction Act may lead to a green bank that could support just transition efforts.EU R&D policy supports not only technology development but also innovation in the creation of stronger social institutions as a tool for responding to just transition challenges. The US federal government could do more to support research and pilot implementation of innovative approaches for addressing just transition. |

| Abstract: | In Climate Insights 2024: Americans Understanding of Climate Change, we showed that huge majorities of Americans believe that the earth has been warming; that this warming is due to human activity; and that governments, businesses, and individuals should take steps to address it. In Climate Insights 2024: American Climate Policy Opinions, we described how large majorities of Americans favor various policies for mitigating future global warming. Yet, these mitigation policies cannot be achieved without many Democrats, Independents, and Republicans agreeing.In this report, we assess the degree to which Democrats, Independents, and Republicans agree on various aspects of climate change and climate change policy in 2024. We then use data from prior surveys in our series to track changes in the partisan gap over the past two decades.In recent years, American partisans have been contemptuous of their opponents. According to a national survey conducted by Gallup in 2023, many more Democrats than Republicans held an unfavorable view of the Republican Party (93 percent vs. 13 percent). Likewise, many more Republicans than Democrats viewed the Democratic Party unfavorably (95 percent vs. 7 percent) (Saad 2023). |

| Abstract: | The United States is undergoing an energy transition. The share of electricity sourced from fossil fuels has steadily declined over the past decade, a consequence of both growing concern over climate change and the availability of low-cost renewable energy. Coal has faced a particularly steep decline—once the source of over half of the country’s electricity, it now supplies less than one-fifth (EIA 2022).This shift away from traditional energy sources puts at risk those workers and communities for whom fossil fuel production or industrial use is a key driver of prosperity. Thus, effective stewardship of the energy transition demands that policymakers prioritize fairness and opportunity for these groups. This concept of fairness for economically dislocated workers and communities is widely known as “just transition.”Facilitating a just transition is no easy task, as the challenges facing communities in transition are diverse and deeply rooted. But as the shift away from fossil fuels accelerates, the need for effective methods of intervention—including thoughtful public policy—to address these challenges becomes acute.The experiences of individual communities that have dealt with the loss of fossil fuel–related economic activity can serve as a valuable guide for how to pursue a just transition. This report examines the experience of one such community, Tonawanda, New York, and its process of dealing with the closure in 2016 of the C. R. Huntley Generating Station, a coal-fired electricity plant. For the purposes of this case study, Tonawanda refers to the town of 72, 000 in western New York (US Census Bureau 2021a), not to be confused with the city of Tonawanda, a smaller municipality directly to the north of it, nor with North Tonawanda, a city farther north in Niagara County. Tonawanda includes the village of Kenmore, a semiautonomous suburb of 15, 000 people (US Census Bureau 2019) that has its own mayor and board of trustees but is still subject to Tonawanda’s taxing jurisdiction. Kenmore and Tonawanda share a public school district called the Kenmore-Tonawanda Union Free School District, which includes nine schools that collectively serve almost 7, 000 students (KTUFSD 2020). To understand the impact of the closure and how the community responded, we analyzed tax documents, pollutant reports, municipal budgets, and news coverage. We also conducted a series of telephone interviews in 2020 with the following individuals: Joseph Emminger, Tonawanda’s town supervisor; Richard Lipsitz, president of the Western New York Area Labor Federation, AFL-CIO; Dave Wasiura, assistant director of the local chapter of United Steel Workers; Cindy Winland, director of strategic priorities at Delta Institute; and staff in the Office of Senator Chuck Schumer.The Tonawanda experience provides illustrative examples of how a single facility’s closure can create challenges for local government budgeting and disrupt a variety of industrial operations in the local economy—some of which may be unexpected. Tonawanda also offers insights into how a diversity of stakeholders—including labor unions, environmental advocates, and local government—can work together effectively to facilitate transition, along with how federal and state government programs can provide important financial support. Given the diversified economy of the broader Buffalo metro area, however, the Tonawanda experience may have limited applicability to communities embedded in larger regions undergoing energy transition, such as Central Appalachia, where coal mining has precipitously declined in recent years. In these areas, communities may face larger economic and fiscal challenges, have more complex stakeholder dynamics, and enjoy less support from state government. That said, insights from the Tonawanda case can be helpful for communities undergoing transition of any kind, taken in context. These insights include the following:Start planning early. A proactive approach to transition is essential for securing funding, coordinating stakeholders, and planning redevelopment. Communities and organizations facing a transition should begin planning as soon as it becomes clear that a facility will shut down, and energy companies should endeavor to provide early warning.Formalize the transition. Without dedicated personnel and funding, transition planning can lack focus and lose momentum. To the extent possible, communities should seek to formalize the transition process, such as by establishing a committee or task force charged with creating an open forum for community deliberation, developing policy solutions, and potentially conducting advocacy and implementation.Engage a diversity of stakeholders. Within the sort of civic forum just described, it is important to engage diverse stakeholders early to ensure representation of the variety of community interests that will ultimately have a say in transition and development decisions.Identify a common objective. Clearly defining a common objective at the outset can provide the platform needed for effective cooperation among stakeholder groups.Expect and plan for indirect consequences. Proactive engagement with a diverse array of stakeholders can also help planners anticipate potential indirect consequences of a facility’s closure. For example, the Huntley closure jeopardized the availability of water for industrial uses in Erie County, which historically depended on pumping facilities at the Huntley plant. Energy transition programs should have sufficient flexibility to address local variations.Procure transition funding from state and federal agencies. The retirement of a coal facility can eliminate local government tax revenue, making it difficult to locally fund transition efforts. Dedicated state and federal transition funding can help local governments mitigate the immediate fiscal impact of the shutdown and provide them with a window in which to plan for an economic transition. |

| Abstract: | Literature has shown that air pollution can have short- and long-term adverse effects on physiological and cognitive performance. In this study, we estimate the effect of increased pollution levels on the likelihood of accidents in construction sites, a significant factor related to productivity losses in the labor market. Using data from all construction sites and pollution monitoring stations in Israel, we find a strong and significant causal effect of nitrogen dioxide (NO2), one of the primary air pollutants, on construction site accidents. We find that a 10-ppb increase in NO2 levels increases the likelihood of an accident by as much as 25 percent. Importantly, our findings suggest that these effects are non-linear. While moderate pollution levels, according to EPA standards, compared to clean air levels, increase the likelihood of accidents by 138 percent, unhealthy levels increase it by 377 percent. We present a mechanism where the effect of pollution is exacerbated in conditions with high cogitive strain or reduced awareness. Finally, we perform a cost-benefit analysis, supported by a nonparametric estimation calculating the implied number of accidents due to NO2 exposure, and examining a potential welfare-improving policy to subsidize the closure of construction sites on highly polluted days. |

| Abstract: | What role does bond versus bank debt play in the climate transition? We document that fossil fuel firms with greater stranded-asset risk rely less on bond finance and more on bank credit. While bond investors price stranding risk, banks in the syndicated loan market do not. This differential pricing leads to within-firm substitution from bonds to loans, consistent with a relative contraction in bond market credit supply. We also find that large banks are more likely to lend to risk-exposed firms, raising questions about how climate risk is distributed and whether credit flows align with transition objectives. |

| Abstract: | California is looking to extend its greenhouse gas cap-and-trade program forward in time and to make adjustments to the trajectory of the annual emissions cap. This report looks at the possible reforms suggested by the California Air Resources Board (CARB) using RFF’s Haiku Emissions Market Model. We analyze the allowance price, emissions, revenue, and banking impacts of cap reduction options proposed by CARB given uncertainty about technology, the effectiveness of regulatory programs, investment strategies, economic activity, and banking behavior. We consider the three methods of implementing the “48 percent target cap” adjustment proposed in the Standard Regulatory Impact Assessment (SRIA) that intend to reduce cumulative allowance supply by 265 million tons by 2030:Option A, nominal cap reduction;Option B, partial nominal cap reduction and partial allowance price containment reserve (APCR) reduction; andOption C, APCR reduction.The nominal cap describes the introduction of new emissions allowances in a given year. The emissions outcome will differ from the cap because of the availability of banked allowances and offsets.Additionally, we examine the full set of options included in CARB’s October 5, 2023, workshop (the 40, 48, and 55 percent “budget” and “target” cap reductions) that would achieve cumulative reductions in allowance supply ranging from 115 - 390 million tons by 2030. We also consider the impact of additional potential program design features, including an emissions containment reserve (ECR); facility-specific caps, as suggested by the California Cap-and-Trade Environmental Justice Advisory Committee (EJAC); and modifications to free allocation.Key Findings focusing on the Options A, B, and C for the 48 percent target scenario as identified in the SRIA:Future emissions and allowance price pathways vary across scenarios. In sensitivity analysis investigating uncertain technology and energy demand, we find greater variation in allowance demand, emissions, and prices.Removing allowances from the nominal emissions cap will lead to a higher allowance price. However, removing APCR allowances increases price variability.Although Options A, B, and C appear to have the same cumulative allowance supply, the tighter nominal cap (A) yields lower emissions than B and C, especially if, as CARB’s SRIA assumes and this report reaffirms, APCRs are never triggered.Tightening the cap in any of the ways CARB proposes will increase allowance value above baseline even as allowances decrease, but the choice of where to remove allowances (from auctioned supply or freely allocated allowances, or from the APCR) will have distributional impacts by changing the share of allowance value accruing to the Greenhouse Gas Reduction Fund (GGRF) relative to that accruing to recipients of free allocation.Assuming the program continues beyond 2030, tightening cumulative allowance supply leads to roughly 40 percent reduction in the size of the bank by 2030, after which the bank continues to be drawn down slowly through 2045. Increased cap stringency will raise the value of banked allowances.Adding an ECR would support allowance prices and revenue in low-demand scenarios and reduce uncertainty about prices, revenues, and emissions.Adding facility-specific caps would have very little impact on the market (less than a 2.8 percent increase in allowance prices) but could reduce uncertainty around health outcomes for disadvantaged communities.Looking beyond the 48 percent target scenario options, we consider 40, 48, and 55 percent budget and target cap reductions. We find the qualitative impact of tighter caps on prices, missions, revenue, and banking remains consistent. However, the range of outcomes varies widely, with prices at the floor in the less stringent cases and rising to the price ceiling in the more stringent cases. An ECR, or facility-specific caps, can be added to any of these cap adjustments with the same effects as for the 48 percent target A, B, and C options. |

| Abstract: | This paper studies the adoption of clean technology in an oligopolistic setting, focusing on carbon capture and storage (CCS) in the cement sector. Firms can choose between two technologies: a carbon-intensive ("dirty") technology and a low-carbon ("clean") one. Initially, all firms operate with the dirty technology, whose variable cost increases over time with the social cost of carbon, following Hotelling’s rule. Clean technology has a constant marginal cost but requires a sunk investment cost. Firms engage in short-term Cournot competition, and the adoption decision is modeled as a dynamic game in continuous time. We show that imperfect competition leads to inefficiently delayed adoption due to preemption incentives, with firms eventually coordinating on a late joint adoption equilibrium. We propose two corrective public policies: a fixed-cost subsidy and a time-dependent subsidy on profit flows. Calibrating our model to the cement industry, assuming five competitors, we find that without policy intervention, CCS adoption would occur in 2042 rather than the socially optimal date of 2030. Obtaining optimal timing requires either a 70% fixed-cost subsidy or a time-dependent subsidy equivalent to 20% of that amount, although it requires more information for implementation. |

| Abstract: | Sustainable finance regulations and initiatives across Europe have predominantly targeted large corporations, while small and medium-sized enterprises (SMEs) are increasingly drawn into the framework, often facing challenges such as resource constraints and complex documentation requirements. To capture the dynamics of this field, a European survey conducted in 2025 with responses mainly from German and Austrian companies examined SME engagement with sustainable finance. The findings show a rising share of SMEs investing in sustainability in comparison to the preceding study in 2023, with internal funding as the dominant source. Where external financing is used, it is primarily activated on publicly supported bank loans, whereas capital markets remain largely irrelevant for SMEs. While a connection between sustainability data collection and sustainable investment exists, many SMEs invest without systematically collecting data. These results highlight the continued centrality of traditional banking relationships as the main external financing channel for SMEs, which could serve to enable and facilitate capital flows toward sustainability rather than prescribe or direct them. |

| Abstract: | Arctic and Antarctic climate evolution is crucial for understanding global climate dynamics. This study grounds in the framework of Gadea and Gonzalo (2020, 2025) to analyze different distributional characteristics (beyond the average) of polar temperature measurement as time series objects, enabling the definition and robust testing of polar warming, its acceleration, and amplification. Our findings provide a quantitative description of the warming processes affecting the polar regions. The research examines measurements of temperature in the Arctic (1900-2019) and the Antarctic (1960-2022). Key findings include: (i) Clear Arctic warming since 1900 across all quantiles, with more pronounced warming in lower quantiles since 1950. No significant warming was observed in Antarctica in all of the temperature quantiles; (ii) Arctic warming acceleration since 1960, particularly in lower and middle quantiles, with no apparent peak reached yet; (iii) Consistent Arctic amplification is slightly below 2 and stable across analyzed periods. Lower quantiles (corresponding with winter in the higher latitudes) show larger amplification than the mean. Since 1960, amplification has extended to upper quantiles, except the 90th and 95th percentiles; (iv) Analysis of the internal Arctic amplification shows that this is primarily a lower-quantile phenomenon, Arctic amplification is stronger in higher latitude winters and this affects the speed at which the ice in the Arctic is disappearing. The study’s amplification estimates are lower than some observational studies but align more closely with climate model projections. The paper concludes by comparing these results to the equivalent global temperature trends. |

| Abstract: | In a two recent publications, Carbon Border Adjustments: Design Elements, Options, and Policy Decisions and Foreign Pollution Fee Act: Design Elements, Options, and Policy Decisions, we provided an overview and comparison of current border adjustment mechanisms (BAMs). In the first publication we focused on the European Union’s Carbon Border Adjustment Mechanism (EU CBAM); the Fair, Affordable, Innovative, and Resilient Transition and Competition Act (FAIR Act), sponsored by Senator Chris Coons (D-DE); and the Clean Competition Act (CCA), by Senator Sheldon Whitehouse (D-RI). In the second publication we reviewed a new piece of proposed US Senate legislation, the Foreign Pollution Fee Act (FPFA), introduced by Senator Bill Cassidy (R-LA), Senator Lindsey Graham (R-SC), and Senator Roger Wicker (R-MS). In this report we provide more detail on the EU CBAM and compare it to the FPFA and the CCA, which was reintroduced on December 6, 2023. A great deal of the FPFA description used in this report is reproduced from our publication Foreign Pollution Fee Act: Design Elements, Options, and Policy Decisions. This report uses the design elements introduced in the previous publications to describe the policies reflected in each BAM. We have made every effort to be concise with respect to our descriptions of the design elements, but that has required us to abstract from a great deal of detail in each BAM. We hope this report will provide a roadmap that informs understanding of these mechanisms, but it should not be interpreted as a complete and comprehensive description and review. |

| Abstract: | The Community Disaster Resilience Zones Act of 2022 directed the Federal Emergency Management Agency (FEMA) to designate communities that are vulnerable to natural disasters as Community Disaster Resilience Zones (CDRZs), which would then be prioritized for federal climate resilience funding. FEMA announced the first round of CDRZs in September 2023 – 483 census tracts that are high risk based on FEMA’s National Risk Index mapping tool and disadvantaged based on the White House Climate and Economic Justice Screening Tool. FEMA also followed the CDRZ Act’s mandate that the top one percent of census tracts based on risk in each state be designated as CDRZs, ensuring geographical representation of CDRZ communities.In this study, we summarize the risk and demographic characteristics of the tracts designated as CDRZs and explore two alternative approaches to designation: one that removes the requirement that tracts be disadvantaged based on the CEJST, using only the National Risk Index score, and one that removes the requirement that the top one percent in each state be designated as CDRZs. We also evaluate a potential “round 2” of CDRZs, expanding the list of designated tracts.We find that incorporating disadvantaged status, based on the CEJST, pulls more socially vulnerable, lower income, communities onto the list of CDRZs than would have been the case using the National Risk Index alone. At the same time, the average risk and resilience characteristics of the communities would be approximately the same. If the top one percent in each state requirement was dropped and designations based only on risk rankings and disadvantaged status, we find that only 22 states would have had CDRZs. This is because of the geographic concentration of risks in the United States, especially around the hurricane-prone Gulf Coast. Finally, our “round 2” list includes more relatively disadvantaged communities, with higher poverty rates, lower household incomes, and higher social vulnerability and slightly lower risk scores. This finding suggests that the requirement that communities be disadvantaged may begin to carry more weight in the designation process as new tracts are added to the CDRZ list.Using North Carolina as a case study, we compare CDRZs to communities that would have been selected by local experts and using local risk mapping tools. We find very little overlap in the census tracts chosen as CDRZs and these locally selected alternatives. We conclude from this exercise that some refinement of the approach, bringing in local knowledge along with the two national mapping tools, could be useful in the future. Interviews we conducted with state agencies and nonprofit organizations working on local resilience issues suggest some concerns about the CDRZ process. Most of these revolve around capacity and resource challenges in communities in gathering knowledge about CDRZs and accessing federal funding for resilience. |

| Abstract: | This study looks at how the the climate policy uncertainty (CPU) shocks affect Portugal’s energy sector, specifically examining their effects on turnover, output prices, and labor market dynamics. The structural vector autoregression (SVAR) analysis shows that CPU shocks lead to a significant increase in domestic turnover. Output prices rise both at home and abroad, but foreign prices are more sensitive. The labor market shows a more nuanced reaction, hours worked marginally increase and wages remain unchanged. Furthermore, the study finds that CPU has been a key driver of historical variations in the energy sector, particularly during global policy events like COP26 and domestic policy changes like carbon or car tax changes. These findings establish CPU as significant driver in energy prices and underscore the importance of judicious climate policymaking. |

| Abstract: | Clean hydrogen (H2) fuel can play a role in decarbonizing the heavy-duty transportation sector. Transportation is the biggest source of anthropogenic CO2 emissions within the United States, and medium- and heavy-duty vehicles make up 23 percent of transportation emissions. The heavy-duty transportation sector is defined as commercial vehicles with gross vehicle weight ratings more than 26, 001 pounds and generally includes drayage trucks, short and regional day cabs, and long-haul Class 8 trucks. This sector is particularly difficult to decarbonize, as these trucks often require long ranges and carry heavy payloads. This report provides an overview of H2 truck technology, its current status in the United States, comparisons to diesel and battery electric trucks, challenges to deployment, and policy issues. |

| Abstract: | This paper introduces a novel Bayesian reverse unrestricted mixed-frequency model applied to a panel of nine European electricity markets. Our model analyzes the impact of daily fossil fuel prices and hourly renewable energy generation on hourly electricity prices, employing a hierarchical structure to capture cross-country interdependencies and idiosyncratic factors. The inclusion of random effects demonstrates that electricity market integration both mitigates and amplifies shocks. Our results highlight that while renewable energy sources consistently reduce electricity prices across all countries, gas prices remain a dominant driver of cross-country electricity price disparities and instability. This finding underscores the critical importance of energy diversification, above all on renewable energy sources, and coordinated fossil fuel supply strategies for bolstering European energy security. |

| Abstract: | Transition by the United States to a decarbonized economy by the middle of the century must include transportation, which today accounts for a little less than 30 percent of US greenhouse gas (GHG) emissions and over one-third of total CO2 emissions (EPA 2023; EIA 2023). Among the options for decarbonizing ground transportation, current policy emphasizes increased electric vehicle use along with decarbonizing the power grid and further advances in electric vehicle (EV) technology, especially for EV batteries.Current EV battery designs use significant quantities of so-called critical minerals, specifically lithium, cobalt, manganese, nickel, and graphite. Radically increasing global production and purchases of EVs with these battery designs will lead to order-of-magnitude increases in demand for these minerals (IEA 2022). However, as discussed in Section 2, critical minerals tend to be found mainly in a handful of countries outside the United States. Moreover, the capacity for processing extracted minerals into forms suitable for use in manufacturing EV batteries is highly concentrated in one country, China.Thus, there are substantial concerns about perceived risks to future affordability and reliability of the supplies of these minerals because of the geographic concentration of the supply chains and the economic and political power that dominant mineral suppliers could wield. Another concern is about mineral price volatility, including large price shocks of uncertain duration, which would complicate planning and management for both battery and vehicle manufacturers. Moreover, critical mineral supplies can be increased and diversified only after lengthy periods for exploration and development of new mineral reserves, as well as construction of new processing facilities. In short, the response of critical mineral supplies to higher prices generally is highly inelastic, at least until enough time has elapsed for mineral extraction and processing capacity to expand. As noted in Section 3.4, in the United States that interval often is many years.This paper explores these challenges in greater detail and highlights implications for US policy toward critical minerals. Section 2 reviews key geographic characteristics of critical minerals and uncertainties regarding expanding their supplies within the United States. Section 3 examines critical mineral policies in the United States and their limitations. The final section identifies some priorities for developing critical mineral policy and filling knowledge gaps. |

| Abstract: | Gender equality is associated with economic growth and resilience, yet various factors, including climate change, may stall progress toward equal rights for men and women. This paper analyzes historical temperature and precipitation fluctuations within countries to assess their effect on legal gender equality, using data from the World Bank’s Women, Business and the Law dataset, which measures women’s rights across 190 economies and five decades. The findings reveal that temperature anomalies correlate with slower progress in legal gender equality, particularly in low-income countries. Irregular temperature fluctuations significantly delay the development of legal frameworks for parental leave, marriage, and mobility. Countries, particularly those with limited resources, seem less inclined to provide tangible benefits to women. This study emphasizes the complex relationship between extreme temperatures and women’s rights, highlighting the importance of addressing gender disparities to build more resilient societies, especially in the face of shifts in temperatures and weather patterns. |

| Abstract: | Sustainability and non-financial risk management are becoming increasingly im-portant for German companies due to climate change and new regulations. However, it is un-clear how well companies of varying sizes are prepared to handle the increasing pressure to adapt. While large companies are obliged to publish a sustainability report due to regulatory requirements such as the CSRD, there is no direct obligation for SMEs. Nevertheless, due to external pressure from stakeholders and information requirements of large companies, SMEs increasingly have to address the issue of sustainability. This raises the question as to how far large companies and SMEs have progressed in implementing sustainability, how the costs and benefits of this adaptation process can be compared and what differences can be identified be-tween the two company sizes. Our study is based on a June 2023 survey of 120 companies and provides an overview of the current state of sustainability management in German companies. Further, our results show that large companies have a broader understanding of sustainability than SMEs. In addition, most large companies already implement and report on sustainability measures. Overall, we observe that there is a link between understanding sustainability, imple-menting sustainability measures and sustainability reporting. |
| Abstract: | Nachhaltigkeit und das Management nichtfinanzieller Risiken gewinnen für deutsche Unternehmen aufgrund des Klimawandels und neuer Vorschriften zunehmend an Bedeutung. Es ist jedoch unklar, wie gut Unternehmen unterschiedlicher Größe auf den zuneh-menden Anpassungsdruck vorbereitet sind. Während große Unternehmen aufgrund regulatori-scher Anforderungen wie der CSRD zur Veröffentlichung eines Nachhaltigkeitsberichts ver-pflichtet sind, gibt es für KMU keine direkte Verpflichtung. Dennoch müssen sich KMU auf-grund des externen Drucks von Stakeholdern und der Informationspflichten großer Unterneh-men zunehmend mit dem Thema Nachhaltigkeit auseinandersetzen. Dies wirft die Frage auf, wie weit große Unternehmen und KMU bei der Umsetzung von Nachhaltigkeit fortgeschritten sind, wie die Kosten und Nutzen dieses Anpassungsprozesses verglichen werden können und welche Unterschiede zwischen den beiden Unternehmensgrößen festgestellt werden können. Unsere Studie basiert auf einer Umfrage unter 120 Unternehmen vom Juni 2023 und gibt einen Überblick über den aktuellen Stand des Nachhaltigkeitsmanagements in deutschen Unterneh-men. Darüber hinaus zeigen unsere Ergebnisse, dass große Unternehmen ein umfassenderes Verständnis von Nachhaltigkeit haben als KMU. Außerdem setzen die meisten großen Unter-nehmen bereits Nachhaltigkeitsmaßnahmen um und berichten darüber. Insgesamt beobachten wir einen Zusammenhang zwischen dem Verständnis von Nachhaltigkeit, der Umsetzung von Nachhaltigkeitsmaßnahmen und der Nachhaltigkeitsberichterstattung. |

| Abstract: | Place-based policies designed to support fossil fuel–dependent communities are emerging in the United States and abroad. However, there has been little analysis to understand which, if any, existing place-based economic development policies can serve as models in the energy transition. In this analysis, we review the empirical evidence on the effectiveness of three major federally funded place-based economic development programs, then assess their relevance to the energy transition. We find that existing policies, depending on their design details, can be effective in directing investment and improving local economic outcomes in targeted locations. However, these programs can contribute to neighborhood gentrification, and economic benefits may flow primarily to residents living outside the targeted community. Adapting any of these policies to an energy transition context would require changes in eligibility criteria, geographic targeting, selection mechanisms, and more. We offer several conceptual models for how such policies could be structured but caution that much additional research and community engagement will be needed to determine which mix of interventions is likely to be most effective in ensuring an equitable transition toward a clean energy future. |

| Abstract: | We provide a theoretical micro foundation for how much pollution (negative externalities) a firm will internalize based on the ownership distribution of its shareholders. Small shareholders, compared to large ones, want the firm to spend more on avoiding pollution since they suffer less profit loss for the same environmental benefit. In particular, if a shareholder holds a share of 1/N, where N is the population in society, that shareholder's preferences align with a social planner's. Three theoretical predictions arise. First, small shareholders will systematically vote for a greener corporate profile. Second, firms with a smaller weighted median shareholder will pollute less. Third, countries with concentrated corporate wealth holdings and/or more individualized firm ownership pollute more. This implies that standard models of externalities in environmental economics and macroeconomics containing representative agents are either internally inconsistent or not fully specified. |

| Abstract: | Taking the European Union’s Carbon Border Adjustment Mechanism (CBAM) as given, our paper evaluates the impact of this terms-of-trade shock on the Middle East and Central Asia (ME&CA). Using a novel methodology and fresh data applied to the latest CBAM legislation, we both quantify and decompose the financial burden countries face as their exports to the EU become subject to a greenhouse gas-based fee starting in January 2026. Our analysis reveals that while the average effects of CBAM in ME&CA are modest, the region will shoulder one of the highest burdens worldwide, totaling US$1.7 billion annually (equivalent to 0.03 percent of GDP and a 14 percent surcharge on CBAM exports to the EU). The Middle East, North Africa, Afghanistan, and Pakistan (MENAP) subregion will bear a greater share of this burden than the Caucasus and Central Asia (CCA) due to stronger trade ties with the EU and higher emission intensity. Substantial country- and sector-level differences in CBAM exposure emphasize the need for tailored policy responses to mitigate the broader macroeconomic effects. |

| Abstract: | We present comprehensive experimental evidence that expanding the number of charitable options enhances both donation outcomes and donor experience, suggesting choice deprivation rather than choice overload. In a pre-registered online experiment with over 2, 248 participants donating real money to UK charities (average donation of £1.59 out of £2.50), we find that increasing the number of available charities raises total donations robustly by approximately £0.04. Furthermore, allowing participants to donate to multiple charities, rather than restricting them to one, boosts donations by £0.23 on average, without increasing regret or diminishing satisfaction. Other mediators, difficulty, deliberation, and familiarity, do not explain the impact of treatments on giving behaviour. Our design rules out alternative explanations, including self-interest, ease of donation, or perceived importance of giving, and highlights that more choices encourage thoughtful engagement with the donation decision. The results are highly relevant to the design of consumer-facing interventions in pro-environmental domains, importantly for energy and climate policy. In areas such as carbon offsetting and climate-focused giving, individuals are required to make voluntary contributions or adopt sustainable products. Our evidence suggests that providing diverse and flexible choices can increase contributions in these domains. |

| Abstract: | This paper studies a functional regression model with nonstationary dependent and explanatory functional observations, in which the nonstationary stochastic trends of the dependent variable are explained by those of the explanatory variable, and the functional observations may be error-contaminated. We develop novel autocovariance-based estimation and inference methods for this model. The methodology is broadly applicable to economic and statistical functional time series with nonstationary dynamics. To illustrate our methodology and its usefulness, we apply it to the evaluation of the global economic impact of climate change, an issue of intrinsic importance. |

| Abstract: | Existing wholesale electricity market designs are poorly suited to address challenges associated with the evolving resource mix. For example, recent scarcity events in the United States show that reliability challenges in renewable- and gas-dominated electric power systems arise not from the lack of generation capacity to serve peak customer demand, but from the lack of available capacity to provide the requisite energy at times of need. We review 11 proposed electricity market designs for the clean energy transition and compare them based on 10 criteria. Enhancing reliability in electric power systems with a significant amount of variable renewable energy requires incentivizing resource flexibility, both in investment and in operation. Electricity market structures should allow resources needed for reliability to earn adequate revenues to recover their variable and fixed costs. Good market designs also enable low-cost financing to support investments in capital-intensive resources that are instrumental in meeting decarbonization objectives. An additional property of well-designed markets is promoting short-run efficiency by reducing incentives to exercise market power and supporting efficient renewable curtailment outcomes. Besides achieving reliability, long-run efficiency, and short-run efficiency, some proposals in our review seek to achieve energy affordability objectives and integration with clean energy goals. Our evaluation highlights several open questions and directions for future research: the determination of mandatory purchase obligations of load-serving entities and associated enforcement mechanisms; the interplay between long-term hedging requirements and incentives for demand participation in real time; and the compatibility between long-term contract design and efficient operations in short-term energy markets. |

| Abstract: | As shortages of resources like water and electricity due to extreme weather events become more frequent, high prices alone may fail to curb demand, making shortages more common. We examine a power limit policy for residential electricity households that rations electricity consumption rather than setting it to zero, as in a traditional rolling blackout. We find that power limits can provide equivalent savings to large blackouts, even when generous. Additionally, due to selection, power limits reduce the number of households affected by a shortage event. We conclude by discussing the welfare consequences of power limits and their heterogeneous impact across households. |

| Abstract: | German fisheries are regulated under the EU Common Fisheries Policy (CFP). As a Federal Republic, Germany has five coastal federal states that collaborate to implement the CFP. These states are responsible for the implementation of structural policy measures - particularly those related to the European Maritime, Fisheries and Aquaculture Fund (EMFAF) - as well as for regulating coastal waters up to 12 nautical miles (nm). Every federal state has its fishery authority, responsible for inland fisheries, aquaculture, recreational fisheries, and marine fisheries in coastal waters. Management beyond coastal waters in the exclusive economic zones (EEZ) takes place at the national level through the Federal Office for Agriculture and Food (BLE). The utilization of the EEZ is governed by marine spatial plans, where fisheries have either no or minimal priority areas.One of the main management tools is the allocation of fishing quotas. Most of the fishing quotas in Germany are attached to fishing vessels. A permanent transfer of quota is only possible by purchasing or selling vessels. Nonetheless, short-term and non-permanent quota swaps between fishers within a season are possible. Furthermore, there are community quotas not allocated to individual vessels but open for all fishing companies licensed for those fisheries. Those quotas are mostly for managing by-catch species in fisheries on more important stocks where the vessels have individual quotas. Fishing rights of SSF can also be regulated through technical measures, such as the limitation of space for trap nets, a maximum length of gillnets, number of traps and hooks per fisher and area and through closed seasons or closed fishing grounds... |

| Abstract: | The record-breaking heat in recent years, along with other extreme weather conditions worldwide has not only warned us about the devastating effects of global warming but also revived our interest in studying sustainability risks on a broader scale. In this paper, we propose a generalised model of sustainability risks characterising the economic-environmental-social nexus (EVS) based on a classic Lotka-Volterra framework. Compared to the World3 model proposed by Meadows et al. (1972) in their landmark study "The Limits to Growth", our model has numerous advantages such as i) better analytical tractability, ii) more representative characterisation of economic development arising from innovation, and iii) can be adopted in many potential applications of modelling sustainability risks from its sub-dynamics. |

| Abstract: | Over the past decade, climate-related litigation targeted at both public and private actors has mushroomed. This includes some high-profile cases brought directly against banks. Such litigation trends pose material financial risks to banks. In addition, credit institutions need to manage risks related to the rapidly evolving landscape of climate litigation against corporate clients. How banks identify, manage and mitigate these novel legal risks is of strong relevance from the perspective of prudential policy and the effectiveness of transition policies more broadly. To respond to this challenge, this report investigates how credit institutions engage with climate- and environment-related legal risks. It explains how insights from bank current practice, such as gaps in their legal risk management approaches, should be addressed with targeted prudential policy interventions. |

| Abstract: | We investigate the salience of extinction risk as a source of impatience. Our framework distinguishes between human extinction risk and individual mortality risk while allowing for various degrees of intergenerational altruism. Additionally, we consider the evolutionarily motivated "selfish gene" perspective. We find that the risk of human extinction is an indispensable component of the discount rate, whereas individual mortality risk can be hedged against - partially or fully, depending on the setup - through human reproduction. Overall, we show that in the face of extinction risk, people become more impatient rather than more farsighted. Thus, the greater the threat of extinction, the less incentive there is to invest in avoiding it. Our framework can help explain why humanity consistently underinvests in mitigation of catastrophic risks, ranging from climate change mitigation, via pandemic prevention, to addressing the emerging risks of transformative artificial intelligence. |

To understand how our energy system is changing, each year a variety of organizations produce long-term projections that imagine a wide range of futures based on divergent visions about policies, technologies, prices, and geopolitics.Because these projections vary widely and depend heavily on their varied assumptions and methodologies, they are difficult to compare on an apples-to-apples basis. In this report, we apply a detailed harmonization process to compare 16 scenarios across eight energy outlooks published in 2023, as well as two historical data sources. Taken together, these scenarios offer a broad scope of potential changes to the energy system as envisioned by some of its most knowledgeable organizations. Table 1 lists the historical datasets, outlooks, and scenarios examined here, and additional detail is provided in Section 4. |

| Abstract: | This paper examines the untapped fiscal potential of natural resources in the Central African Republic, focusing on the forestry and mining sectors. The paper analyzes current production levels, tax systems, and revenue generation in both sectors, and identifies significant opportunities for increased domestic resource mobilization, currently estimated to be between CFAF 150 billion and CFAF 180 billion. The forestry sector, contributing 2.6 percent of gross domestic product and 47.4 percent of exports, generated CFAF 3.7 billion in annual revenues from the main forestry taxes over 2020–21. However, it operates well below capacity, with industrial logging concentrated on just four species, representing 70-75 percent of production. Through modeling three scenarios of improved resource utilization and processing, the study demonstrates potential forestry revenue increases of 75.7 to 145.9 percent, reaching CFAF 6.5 billion to CFAF 9.1 billion, not accounting for potential second round impacts on general taxation. The mining sector, primarily artisanal gold and diamond extraction, contributes 0.6 percent of gross domestic product and 46.5 percent of exports, generating CFAF 2.0 billion in revenues (in 2022). The analysis of the 2024 mining code reforms suggests that revenues could potentially reach CFAF 6.4 billion, primarily through new production-sharing requirements. The paper proposes targeted policy recommendations, including strengthened monitoring and law enforcement, increased investment, simplified taxation for forestry, and improved control mechanisms for mining operations, while noting that the current mining tax system's regressive nature may discourage formalization and investment over the long term. |

| Abstract: | This thesis exploits the 2014–15 Flint Water Crisis as a quasi-natural experiment to examine how a severe public health and governance failure affects electoral participation. Leveraging precinct-level turnout data for gubernatorial and presidential elections in Genesee County (1998–2020), I employ an event-study difference-in differences design with fixed effects and controls for population and partisan composition. I find that, relative to neighboring precincts, voter turnout in Flint City declined by between 20 to 30% in the elections immediately following the crisis, a pattern that persists but loses statistical significance under “honest” bounds (Rambachan & Roth 2023) and synthetic DiD (Arkhangelsky et al. 2021) robustness checks. A parallel analysis of Republican vote share fails the pre-trend test, suggesting greater volatility in party support. These results highlight how a cute institutional failure can erode democratic engagement, even in voluntary voting systems. The findings contribute to the literature on political behavior by providing causal evidence that exogenous shocks to public trust and welfare can suppress turnout, with implications for debates on accountability and institutional resilience. |

| Abstract: | I study the informational value of community resilience in credit markets during natural disasters. Exploiting a severe flood in Germany in 2013, I combine loan-level data on car loans with a composite measure of community resilience based on structural local characteristics linked to disaster recovery capacity. After the flood, only low-income borrowers faced credit tightening, but in high-resilience areas they experienced smaller rate hikes and maintained access to credit. Resilience also predicts repayment after disasters, yet banks ignore it in normal times. This state-contingent reliance shows that community resilience enters credit pricing only in crises, when its information content beyond standard borrower characteristics is valuable enough to justify adoption. |

| Abstract: | This paper contributes to the limited literature on the temperature sensitivity of residential energy demand on a global scale. Using a Bayesian Partial Pooling model, we estimate country-specific intercepts and slopes, focusing on non-linear temperature response functions. The results, based on data for up to 126 countries spanning from 1978 to 2023, indicate a higher demand for residential electricity and natural gas at temperatures below -5 degrees Celsius and a higher demand for electricity at temperatures above 30 degrees Celsius. For temperatures above 23.5 degrees Celsius, the relationship between power demand and temperature steepens. Demand in developed countries is more sensitive to high temperatures than in less developed countries, possibly due to an inability to meet cooling demands in the latter. |

| Abstract: | This study systematically reviews the literature that quantifies the economic benefits of weather observations and forecasts in four weather-dependent economic sectors: agriculture, energy, transport, and disaster-risk management. The review covers 175 peer-reviewed journal articles and 15 policy reports. Findings show that the literature is concentrated in high-income countries and most studies use theoretical models, followed by observational and then experimental research designs. Forecast horizons studied, meteorological variables and services, and monetization techniques vary markedly by sector. Estimated benefits even within specific subsectors span several orders of magnitude and broad uncertainty ranges. An econometric meta-analysis suggests that theoretical studies and studies in richer countries tend to report significantly larger values. Barriers that hinder value realization are identified on both the provider and user sides, with inadequate relevance, weak dissemination, and limited ability to act recurring across sectors. Policy reports rely heavily on back-of-the-envelope or recursive benefit-transfer estimates, rather than on the methods and results of the peer-reviewed literature, revealing a science-to-policy gap. These findings suggest substantial socioeconomic potential of hydrometeorological services around the world, but also knowledge gaps that require more valuation studies focusing on low- and middle-income countries, addres sing provider- and user-side barriers and employing rigorous empirical valuation methods to complement and validate theoretical models. |

| Abstract: | President Biden issued Executive Order (EO) 14008, Tackling the Climate Crisis at Home and Abroad, during his first week in office in January 2021. The EO includes a directive that 40 percent of the benefits of certain federal climate and energy investments flow to communities that are disadvantaged, marginalized, and overburdened by pollution. Nearly three years after its launch, the Justice40 initiative now covers 518 programs across 16 federal agencies.In this study, we take stock of Justice40 implementation. The report is divided into two parts. In the first part, we describe the basics of how Justice40 works and the timeline of program design and implementation since the EO, followed by a discussion of specific challenges the initiative faces and opportunities it provides. In the second part of the report, we assess the pace of Justice40 progress across 445 programs based on program-level analysis, including reviews of federal funding opportunities and conversations with agency staff.Justice40 TimelineThe White House released interim guidance for Justice40 in July 2021. That guidance delegated many decisions to agencies, including which programs are covered by Justice40 and how to measure and define benefits. Agencies were directed to submit benefits methodologies to the Office of Management and Budget (OMB) by December 2021. In February 2022, the White House released a beta version of a new screening tool for identifying disadvantaged communities for the purposes of Justice40. The Climate and Economic Justice Screening Tool (CEJST) was finalized in November 2022 after a public comment period. In January 2023, the White House issued an addendum to the interim guidance, which stated that agencies must fully transition to using the CEJST by October 1, 2023, for the purposes of implementing Justice40. A list of 463 Justice40-covered programs was released in April 2023. A new list of 518 programs was released at the end of November 2023; this list removed a handful of programs that had been on the April list and added programs from the Inflation Reduction Act.Justice40 Implementation ChallengesThe first challenge in Justice40 implementation is related to how federal funding programs work. The federal government sends money to state and local governments and directly to individuals, households, farmers, and other entities. Some funding goes to states in the form of block grants or formula categorical grants, in which money goes to states based on particular rules and formulas and states are given latitude in how and where to spend the money. In these programs, it may be difficult for federal agency staff to ensure that 40 percent of funds (and benefits) ultimately go to disadvantaged communities. With project categorical grants, state and local governments apply for federal funding, usually in a competitive process, to pay for specific projects and activities. In these cases, federal agencies have more control over where the money goes, but the ability to direct it to underserved communities depends on how many of those communities apply for funding. Many underserved communities lack the capacity and resources to undertake what can be an arduous application process. As a result, federal agencies may have a limited pool of applicants that makes it difficult to reach the 40 percent goal. A similar problem can arise in programs that provide financial assistance directly to individuals and households.The second Justice40 challenge is associated with the definition of disadvantaged communities. Agencies are required to use the CEJST to identify which communities are disadvantaged for the purposes of Justice40. Although CEJST has some strengths, it also has some limitations. The first is that it does not include race among its criteria, even though many studies have shown race to be a determining factor—possibly the most important factor—in who bears the burden of environmental injustices. A second is the reliance on national census tract level data to populate the tool. Census tracts are a geography that can be problematic in some areas, especially rural areas, because of the wide heterogeneity in socioeconomic characteristics of the population within the tract. Moreover, some well-recognized environmental problems are not captured in the tool because national data are not available.Defining the benefits of federal investments is the third challenge in Justice40 implementation. The language in the EO explicitly states that the “benefits of certain federal investments”, not the dollar amounts of the investments themselves, should flow to disadvantaged communities. For many federal programs, this aspect of Justice40 is proving the most difficult. In most cases, thus far, the best that is being done is measurement of the investments; in a few programs, other outcomes—contaminated site cleanups, for example—are being measured. The Department of Energy (DOE) has developed a list of eight benefits criteria that must be individually addressed in funding applications.Justice40 OpportunitiesDespite the implementation challenges, Justice40 is also providing some opportunities. We identified five.The first is the improvement in data measurement and collection that the initiative seems to be bringing about. To figure out whether the 40 percent goal is being met, agencies need to be able to track exactly where spending occurs and benefits are delivered. Ultimately, this should allow better program evaluation, even beyond Justice40.The second opportunity is the development of new technical assistance programs in federal agencies. As we stated above, unless agencies receive a pool of funding applicants that includes disadvantaged communities, they may not be able to meet the Justice40 goal, and the technical hurdles in many grant applications are often overwhelming for disadvantaged and underresourced communities. The new programs should help.The third opportunity Justice40 presents is the ability of the federal government to lead by example on justice and equity. Many decisions on environmental policy and infrastructure investments fall to state and local governments, but the federal government has enormous policy influence. It generally brings larger amounts of money to problems than individual states, sets national standards and regulations, provides information and technical assistance, and defines priorities in ways that states often follow. Thus, Justice40 could have a ripple effect at lower levels of government.A fourth opportunity is provided by the setting of a specific numerical target. Compared to procedural requirements, agency strategic plans, equity scorecards, and the like, Justice40 sets a goal based on program outcomes. One may question whether 40 percent is the “right” number, but it provides a quantitative focal point.Finally, the Justice40 initiative is improving community engagement in federal programs. Engagement with disadvantaged communities is a requirement laid out in EO 14008 and in the initial Justice40 guidance released by the White House in July 2021. While stakeholder engagement has long been a part of many federal government programs, the specific focus on engagement with disadvantaged communities is new.A Status UpdateWe began our review of implementation progress with the programs listed on the April 2023 Justice40 covered programs list. We reviewed 445 of the 463 programs on that list. The Department of Energy has the most covered programs at 165. The agencies with the second- through fourth-most programs are, respectively, the Environmental Protection Agency with 73, and the Departments of Agriculture and the Interior with 65 each.We devised a 1-5 scale for measuring the status of implementation. A rating of 1 indicates that we were unable to find any information about Justice40 for the program, including in funding announcements and on program webpages. Programs received a 2 if we found acknowledgement that the program was covered by Justice40 but no additional information. A rating of 3 was assigned to programs that provided preliminary Justice40 implementation guidance but no clear information on funding prioritization methods. A rating of 4 indicates that we found thorough program-specific Justice40 guidance, including clear definitions of prioritization metrics, but no statement (yet) that 40 percent or more of investments (or benefits) currently go to, or definitely will go to, disadvantaged communities. Category 5 indicates full implementation and achievement of the 40 percent goal. We divided 5 into two subcategories: 5A are programs that state that 40 percent or more of investments/benefits are currently going to Justice40 disadvantaged communities or will go to disadvantaged communities through set-asides and specific requirements; 5B are tribal and low-income programs that “automatically” achieve the Justice40 goal. All tribal communities are defined as disadvantaged for purposes of Justice40, and we made a decision to assign programs that are limited to low-income populations also to the 5B category. We could not track down reliable information for 42 programs on the April 2023 covered program list and thus left them uncategorized (U).The following table summarizes our findings. |

| Abstract: | With implementation of the Infrastructure Investment and Jobs Act (IIJA) and the Inflation Reduction Act (IRA), the US Department of Energy (DOE) will play a central role in driving the technological innovations needed to reach the Biden administration’s net-zero greenhouse gas emissions goal. However, it needs additional capacity in several areas, including how best to pick winners for the demonstration projects it will be funding. We held a workshop on this topic and developed a follow-on white paper (Bergman et al. 2023). Another area, the topic of this paper, is establishing the capacity to operationalize and institutionalize impact evaluations, which includes developing approaches for tracking data to support evidence-building and help evaluate DOE’s research, development, and demonstration (RD&D) programs. Strengthening evaluation capacity is important for two reasons: it permits DOE and other interested parties to evaluate the success of programs in advancing and, ultimately, commercializing technologies; and it provides input to the agency for adaptive learning to improve its guidance to applicants (in the Funding Opportunity Announcements [FOAs]), decision protocols, and data collection.These two key pieces of legislation are not the only motivation for developing better program evaluations within DOE. The Evidence Act of 2018 US Congress, The Foundations for Evidence-Based Policymaking Act of 2018, HR 4174, Pul L 115-435, 115th Congress, signed into law in January 2019. aims to modernize federal government data collection and management processes to better inform policy decisions. It requires agencies to assess their evaluation practices and create a plan to develop evidence-building activities. The Office of Management and Budget (OMB) is charged with improving these activities and evaluation by providing guidance and resources to agencies and engaging with evaluation officers; at DOE, each individual office is responsible for both functions (DOE 2022), with program managers in charge of conducting evaluations while following program evaluation standards (OMB 2020).This paper builds on a workshop held by Resources for the Future (RFF), informed by government publications and the academic literature, on evaluation and provides recommendations for building evaluation systems for DOE programs. Evaluation systems cover all the operational, organizational, and institutional elements that are needed, including human resources, organizational capacities, and evaluation practices. The report covers three topics: the state of program evaluation at DOE and in other relevant agencies, institutionalization of program evaluation within DOE, and characteristics of robust evaluation methods and their associated metrics and data needs. It closes with a series of recommendations. |

| Abstract: | Within the Inflation Reduction Act (IRA), corporate tax credits are the largest source of clean energy funding, so understanding how these credits function is important to market participants and policymakers. In this report, I focus on the IRA’s authorization for both utility-scale solar and wind projects to choose between the investment tax credit (ITC) and production tax credit (PTC). After reviewing the history of the ITC and PTC, including the changes made by the IRA, I consider how the three primary owners of utility-scale solar and wind projects—project sponsors, tax equity investors, and regulated utilities—will decide between incentives. I find that the PTC, in most cases, will be strongly preferred by regulated utilities and project sponsors, but the latter’s preference must be weighed against the interests of tax equity investors, which may favor the ITC. Next, I assess how the ITC and PTC may distort project decisions, with the ITC leading to higher-cost electricity and the PTC leading to lower-value electricity. Because the PTC is likely to be the incentive chosen by most utility-scale solar and onshore wind projects, I discuss technology and policy options to raise the value of electricity from PTC projects. |

| Abstract: | Specific concentrations of volatile organic compounds (VOCs) are perceived differently by the human sense of smell, causing either pleasant or unpleasant sensations and potentially leading to sensory irritations. The objective of this project was to evaluate the effects of VOC profiles and concentrations of various woods on overall sensory perception and characteristic patterns in the electroencephalogram (EEG). This purely chemical representation of wood was accompanied by congruent and incongruent visual cues. The study investigated the effects of typical wood VOCs on neurophysiological processes and other chemosensory effects. The first work package examined the multisensory integration of olfactory stimuli in the context of wood, while the second work package included detailed studies on the effects of VOCs from wood at different concentrations to capture both positive and negative impacts on health and well-being. As part of another work package, the extent to which the odour evaluation of wood products is influenced by different visual contexts and prior information was investigated... |

| Abstract: | This paper presents an empirical application of the Gause-Witt model of population ecology and ecosystems to the income distribution competitive dynamics of social classes in economic systems. The Gause-Witt mathematical system of coupled nonlinear first-order ordinary differential equations employed to model population of species sharing the same ecological niche and competing for the same resources was applied to the income data of Brazil. Previous studies using Brazilian income data from 1981 to 2009 showed that the complementary cumulative distribution functions built from yearly datasets have two distinct segments: the lower income region comprising of about 99% of the population can be represented by the Gompertz curve, whereas the richest 1% is described by the Pareto power-law. The results of applying the Gause-Witt system to Brazilian income data in order to describe the distributive competition dynamics of these two population shares indicate that the 99% and 1% income classes are mostly in the dynamic state of stable coexistence. |
