| Abstract: | Addressing the urgent challenge of climate change is a paramount global concern, with European economies showcasing commitment through the ambitious European Green Deal, COP, and sustainable development goals. However, the region's reliance on fossil fuels raises questions about the initiatives affecting the environmental neutrality goals in Europe. To find an answer to this, the present study investigates the impact of energy intensity and environmental tax revenues on environmental management efforts in terms of air, water, and waste pollution abatement in Europe by utilizing data spanning 1994 to 2020 for major European economies that held over 95 % of European economic output. The sample is grouped into two panels based on economic growth level. The study employs advanced econometric techniques to perform the preliminary checks, and GMM-PVR is used as the main study model. Aggregate panel findings reveal significant associations between energy intensity, environmental tax revenues, and environmental management. Notably, higher energy intensity is positively linked to increased environmental management activities, reflecting a commitment to address abatement goals and indicating funds are allocated toward pollution mitigation, aligning with Europe's emphasis on sustainability. Foreign direct investment has a negative relationship with environmental management. However, in Panel A, environmental tax revenues, economic growth, and trade openness reveal a negative impact on environmental management, suggesting that intense economic activities surpass the environmental tax revenue efforts to abate pollution, unlike Panel B, which is effective in pollution reduction. The study's policy implications stress enhancing the energy efficiency of economic giants while simultaneously strengthening mechanisms for utilizing environmental tax revenues and reinforcing environmental regulations to align foreign direct investment with sustainable practices. International collaboration is essential to ensure trade relations align with environmental goals, contributing to global efforts to combat climate change. |

| Abstract: | This study aimed to examine the reasons behind the wait-and-see and resistant attitudes of local elected officials regarding energy transition projects. Although there is consensus on the importance of renewable energy in combating climate change, its implementation at the local level often encounters opposition from several actors, including elected officials. This study identified the internal, external, and personal factors that influence this opposition by conducting semi-structured interviews with the French officials and stakeholders involved in the energy transition and by analysing the local and regional press. Our findings indicate that political strategies, regulatory complexities, and personal beliefs play significant roles in shaping officials' decisions regarding energy transition projects. Furthermore, by proposing a typology of elected officials according to their modes of opposition, we offer insights to promote effective and sustainable local energy transitions. |

| Abstract: | As climate change intensifies so does its salience and potential politicization in the news media. In line with asset-specific views of climate politics, we propose a framework to explain variation in climate reporting based on the interplay of local ecological risks from climate change and anticipated economic vulnerabilities linked to the energy transition away from fossil fuels. We argue that media responses to climate shocks depend on the relative presence of climate-vulnerable populations versus fossil-fuel stakeholders, and propose that different local configurations of asset-holders affect climate coverage and attribution in the media in different ways. In areas without a dominance of organized fossil fuel interests, ecological shocks generate more extensive media climate coverage and clearer links to fossil fuel emissions. By contrast, in local communities where carbon-intensive industries are very strongly embedded, climate coverage is dampened and attribution less frequent. We test these expectations using original media content data in cross-national and sub-national Global South contexts as well as elite interviews conducted in Brazil and Indonesia. Our findings show that fossil fuel presence crucially moderates both the volume and framing of climate reporting. The results highlight how carbon interests can constrain climate discourse at precisely the moments when public engagement with climate issues is most likely. |

| Abstract: | ASEAN is entering a decisive phase in its energy transition. Regional energy demand is projected to rise substantially in the coming decades, while continued reliance on imported fossil fuels exposes economies to price volatility and supply disruptions. At the same time, climate risks are intensifying, underscoring the urgent need to accelerate decarbonisation without compromising economic growth. Bioenergy – derived from agricultural and forestry residues, organic waste, and energy crops – sits uniquely at the intersection of these dual imperatives. As the region’s most abundant renewable energy resource, bioenergy can support energy security, create rural livelihoods, enhance residue management, and deliver substantial emissions reductions when sustainably developed. Yet expectations must be balanced with realistic assessments of land and water availability, logistics, technology readiness, and sustainability governance. Overestimating the resource base or underestimating supply chain constraints risks undermining credibility, investment, and long-term policy goals. To ensure bioenergy contributes meaningfully to ASEAN’s energy transition, policymakers should prioritise waste and residue feedstocks, strengthen sustainability certification, invest in logistics infrastructure, foster technological innovation advance regional cooperation, and intraregional trade. Bioenergy will not replace fossil fuels outright, but as part of a diversified energy mix, it can help reduce reliance on fossil fuels, curtail waste burning, and support a just and inclusive transition – if governed with discipline and pragmatism.

| Abstract: | This paper studies how global warming affects deforestation and agricultural land use. Using high-resolution satellite data on global temperature, deforestation, and land cover from 2001 to 2019, we find that extreme heat shocks to agricultural productivity cause large and persistent forest loss on the world’s agricultural frontier. This effect is strongest in the tropics, in areas growing the most temperature-sensitive crops, and in regions with the most inelastic demand for agricultural products, and it does not seem to be offset by international spillovers. Moreover, we show that deforestation in response to extreme heat can be explained almost entirely by cropland expansion. We corroborate these findings using agricultural census data from Brazil, where we find evidence for a mechanism whereby heat reduces yields and raises local agricultural prices, driving cropland expansion but little land use or input adjustment along other margins. Our estimates imply that extreme heat has driven substantial forest loss and that projected warming through 2100 could lead to an additional 28 million hectares of deforestation. Our findings challenge the view that reallocation will soften the environmental consequences of climate change, suggesting instead that farmers double down and expand cropland locally when productivity falls. |

| Abstract: | Countries with a low share of global emissions may perceive their cooperation in decarbonization as less critical yet economically burdensome. While non-cooperating countries may benefit from reduced global emissions at lower direct costs, they can also face significant environmental consequences. This paper investigates an asymmetric scenario in which most countries engage in decarbonization efforts while a single country adopts a free-riding strategy, focusing on Mexico as a case study. Our study provides insights into investment needs compared to environmental implications for a country with a free-riding strategy. The investment needs under free-riding tend to be higher than a baseline scenario with globally low mitigation, and the environmental impacts significantly higher than initially considered. At the same time, the additional investment required in a globally coordinated decarbonization scenario may be smaller than expected: our results for Mexico show a Below 2C scenario requiring 20% more investment than the baseline, but only 11% more than the asymmetric scenario. These findings highlight the complex trade-offs faced by non-cooperating countries and emphasize the need to account for both economic and environmental dimensions along with global interactions when developing climate policy strategies. |

| Abstract: | The Congo Basin, comprising the world's second-largest tropical rainforest, presents both critical environmental challenges and unique opportunities for sustainable development. This chapter evaluates key pathways for environmentally sustainable development in the region, with an emphasis on extractive industries, renewable energy, agroforestry, biodiversity conservation, ecotourism, and climate and carbon finance. Using regional indicators such as the Fragile States Index (FSI), Human Development Index (HDI), and Environmental Performance Index (EPI), the authors highlight the structural barriers—including weak governance, institutional fragility, and extreme poverty—that constrain the region's development trajectory. Despite these challenges, the Basin's ecological wealth offers potential for transformative interventions. Strategies such as Reduced-Impact Logging for Climate (RIL-C), sustainable mining practices, decentralized renewable energy systems, and integrated agroforestry models are analyzed for their capacity to reduce emissions, protect biodiversity, and enhance local livelihoods. The chapter further explores the potential of REDD+ and emerging carbon market frameworks to finance conservation and climate mitigation efforts. Emphasizing the role of participatory governance, indigenous knowledge systems, and scientific innovation, the chapter underscores the necessity of context-specific, cross-sectoral approaches to operationalize sustainability in one of the planet's most ecologically and geopolitically complex regions. |

| Abstract: | Urban mobility-related emissions are a growing concern in rapidly expanding cities, driving the need for robust methods to assess and mitigate their environmental impact. Here, we focus on developing a multi-agent model to estimate emissions in Riyadh city as the primary case study. Specifically, this study employs the dynamic traffic simulator, METROPOLIS2, to examine mobility-related emissions and their environmental impact. The framework integrates a cleaned road network, an origin–destination matrix for 162 zones with node– zone assignment, and a simplified metro layer. The model is calibrated to reproduce observed congestion patterns and verified through day-to-day dynamics—convergence in departure/arrival times, route reallocation under congestion, and distance–emissions comovement under a homogeneous fleet. We report generalized cost and emissions indicators at the trip and network levels. The contribution is methodological: a transparent, reproducible baseline for Riyadh that enables credible scenario evaluation. |

| Abstract: | This paper examines the patterns and mechanisms of global clean technology diffusion over the last two decades. We document four stylized facts: uneven sectoral progress favoring power and light transport; China’s dominance in innovation and manufacturing; the role of modularity in driving cost declines; and limited adoption in developing economies. Through case studies of solar, electric vehicles, and hydrogen, we analyze how policy and infrastructure enable scale. Finally, we assess emerging challenges for the next phase of diffusion, including critical mineral constraints, artificial intelligence, and geopolitical fragmentation. |

| Abstract: | We examine whether exposure to climate change-related natural disasters is associated with adolescents' aspirations to work in green occupation. Understanding adolescents' aspirations for such occupations is crucial for ensuring a workforce with green skills to contribute to the mitigation of climate change. Combining individual-level data on occupational aspirations, job task data for measuring the greenness of occupations, and administrative data on disaster events, we find that adolescents who were exposed to a natural disaster aspire to occupations with a higher percentage of green job tasks. The result of this exposure is stronger for individuals who are more environmentally aware or more likely to believe that environmental issues will improve. |

| Abstract: | The advancement of renewable energy an essential stage toward achieving a low-carbon energy transition, with finance sector playing a significant role in this process. This study analyzes the impact of financial development on renewable energy technology innovation across 30 Chinese provinces from 2007 to 2019, focusing on key financial dimensions such as banks, bonds, stocks, and foreign direct investment. The research indicates that financial development significantly enhances innovation in renewable energy technology. Further heterogeneity analysis indicates that the inherent advantage of renewable energy resources impedes the pace of substitution for renewable energy technology innovation, while more market-oriented regions can more easily occupy the high value-added renewable energy technology innovation. The development pace of renewable energy technology innovation varies across regions, influenced by distinct renewable energy strategies. Foreign direct investment has produced contrary effects. The moderation test indicates that both investment-based and cost-based environmental regulations enhance the positive effect of financial capital on renewable energy technology innovation. The results establish a theoretical foundation for advancing renewable energy technology innovation and offer practical insights for facilitating the low-carbon transition in developing economies. |

| Abstract: | Boosting climate mitigation funding from advanced economies (AEs) to emerging markets and developing economies is critical to achieving the temperature goal of the Paris Agreement. Understanding the narratives that drive public opinion and influence decision-making on funding mitigation abroad can help inform the design and communication of carbon market and climate finance policies that unlock more effective international climate cooperation. At an international dialogue convened in September 2025, experts from 14 AEs explored prominent public narratives on funding mitigation abroad and opportunities to shift those narratives for better outcomes. Core narrative themes related to the generation of benefits for both funders and hosts, the management of climate target risks, the integrity of funded mitigation, and national interests. To encourage public support, participants suggested reframing funding mitigation abroad in terms of partnering with others to tackle a global, collective issue; creating new market opportunities benefiting funders; investing in global and regional stability; reinforcing broader national objectives and processes; enhancing global mitigation effort; and finding the political middle ground. Participants recommended appealing to universal principles, values, and emotions. To build public trust in funding mitigation abroad, participants emphasised the importance of ensuring high-integrity carbon market and climate finance approaches, encouraging country-specific narratives from credible voices, and enabling more public participation and transparency in government decision-making processes. These insights highlight the need for deeper and more systematic research across diverse AEs to understand and transform public narratives on funding mitigation abroad. |

| Abstract: | Climate change and food systems are now key priorities on global and national agendas, with resilience emphasized at the 2021 UN Food Systems Summit and COP28 in 2023. Food systems include all stages from input production to consumption and waste, contributing about one-third of global greenhouse gas emissions. Industrialized countries are major emitters due to their production and consumption patterns, while developing countries, though less responsible, face greater climate impacts. This chapter analyzes both emission sources within food systems and climate change's effects, especially on post-production stages. It highlights increasing food security risks, particularly in low-income countries. |

| Abstract: | Coastal areas are mobile natural environments that are subject to changes in natural phenomena (lithosphere, hydrosphere, atmosphere) and anthropogenic actions, modifying ancient balances and increasing societal vulnerabilities. Shaped by waves, softened or hardened by climate, they are threatened by the forces of nature and human beings. Their sustainable management has become a major concern, especially in African countries weakened by the acceleration of climatic and societal changes. This study focuses on the territorialization and residentialization of the seaside resort of Cap-Skirring, located in the extreme south-west of Senegal. It looks at the anarchic occupation of its coastal areas by tourism, which has become a threat to the coastline even though it contributes to economic development. The aim is to analyze the political, socio-economic and environmental stakes of tourism development on the coast. The methodology used is based on documentary research, participatory observations and the collection of both quantitative and qualitative data. The results show that the development of seaside tourism has led to an increase in the local population, which poses a threat to ecosystems. They also show that the lack of integrated coastal zone management and the absence of a tourism development plan have led to land pressure in the area, potentially causing an ecological crisis. |
| Abstract: | Les espaces littoraux représentent des milieux naturels mobiles qui sont soumis aux évolutions des phénomènes naturelles (lithosphère, hydrosphère, atmosphère) et des actions anthropiques, modifiant les équilibres anciens et augmentant les vulnérabilités sociétales. Modelés par le déferlement des vagues, adoucis ou endurcis par le climat, ils sont menacés par les forces de la nature et des êtres humains. Leur gestion durable est devenue une préoccupation majeure surtout dans les pays africains fragilisés par l'accélération des changements climatiques et sociétaux. Cette étude s'intéresse particulièrement à la problématique de la territorialisation et de la résidentialisation de la station balnéaire de Cap-Skirring, située à l'extrême Sud-ouest du Sénégal. Elle se penche sur l'occupation anarchique de ses espaces littoraux par le biais du tourisme, devenu une menace pour le littoral même s'il contribue au développement économique. L'objectif est d'analyser les enjeux politiques, socioéconomiques et environnementaux du développement touristique sur le littoral. La méthodologie utilisée est basée sur les recherches documentaires, les observations participatives et la collecte de données aussi bien quantitatives que qualitatives. Les résultats obtenus montrent que le développement du tourisme balnéaire a favorisé l'augmentation de la population locale, ce qui représente une menace pour les écosystèmes. Ils montrent aussi que le manque de gestion intégrée des zones côtières et l'absence de plan d'aménagement touristique ont engendré des pressions foncières dans la zone, pouvant causer une crise écologique. |

| Abstract: | The wet-bulb globe temperature (WBGT) is a widely used index for assessing heat stress. However, many studies on heat stress under climate change rely on simplified WBGT calculations, which may introduce biases. In this study, high-resolution climate data and the physically-based WBGT model are employed to provide a more reliable assessment of future heat stress impacts across Vietnam and its seven sub-climatic regions. Projected changes are analyzed for three future periods — the near future (2021–2040), mid-future (2041–2060), and far future (2081–2100) — relative to the baseline period (1995–2014) under three Shared Socioeconomic Pathways (SSPs): SSP1-2.6, SSP2-4.5, and SSP5-8.5. Additionally, changes are assessed across different global warming levels (GWL), ranging from 1.5°C to 4°C above the pre-industrial level. Long-term trends throughout the studied period are also examined. The findings reveal significant increases in heat stress across Vietnam in the future. A major concern is the substantial increases in the number of days exceeding impact-relevant heat stress thresholds, most notably in the Red River Delta and Mekong River Delta, two most densely populated and agriculturally critical sub-regions of Vietnam. Heat stress emergence and intensity are closely linked to the radiative forcing of SSP scenarios and the GWLs, with higher forcing scenarios and warmer GWL producing more severe conditions and a greater frequency of exceedance days. The most severe impacts are projected under SSP5-8.5 as well as GWLs of 3°C and 4°C, indicating the urgent need to limit future warming to mitigate the risk of heat stress. Biases in simplified WBGT calculations are also discussed, suggesting significant overestimations of exceedance days in most of Vietnam. Such biases could lead to misleading assessments, unnecessary alarms, and potentially flawed adaptation strategies, highlighting the critical need for accurate WBGT modeling in climate impact research |

| Abstract: | Rapid urban growth in Riyadh is expected to intensify congestion, energy demand, and transport-related emissions, raising the stakes for policy choices that deliver quantifiable results. We develop and apply a calibrated multi-agent model of Riyadh (METROPOLIS2) to compare three levers—targeted electric-vehicle incentives, improved metro accessibility, and telework adoption—and to quantify their effects on traffic, emissions, and traveler welfare. Beyond CO₂, we estimate local pollutants (NOₓ and PM₂.₅) using speed-dependent emission factors, and find that distance-targeted incenves yield larger simulated reductions than uniform EV uptake. At 20% EV share in 2030, targeted incentives reduce CO₂ by 32.3% (vs 20.1% under uniform incentives). For the local pollutants, the corresponding reduction is 26% for NOₓ and 26% for PM₂.₅ (vs 15% for each under uniform incentives). Enhancing first–lastmile metro access cuts annual CO₂ emissions by just over 1 million tonnes and travel times by about 20 percent, while reducing NOₓ by 16.5% (≈4, 451 kg) and PM₂.₅ by 16.6 percent (≈451 kg) per weekday across the network. Telework at 20 percent adoption lowers car use by 5.8 percent and per-trip emissions by 4.6 percent, though non-work trip rebound can erode gains. While these estimates are simulation-based and should be treated as indicative, the results suggest a portfolio logic: concentrate electrification among the city’s highest-mileage drivers, treat metro accessibility as an emissions and air-quality instrument, and pair telework with demand management to preserve environmental gains. |

| Abstract: | In California and many other states, new development projects must undergo an environmental impact analysis as part of the approval process. In California, this happens through the California Environmental Quality Act (CEQA). While CEQA is designed to ensure thoughtful consideration of environmental effects, it can also invite litigation that can delay or derail projects, even for projects that may benefit the environment, such as transit-oriented development (TOD). TOD aims to reduce vehicle miles traveled (VMT) and its associated impacts, such as greenhouse gas emissions (GHGs), by locating housing, jobs, and amenities near high-frequency public transit. But when environmental review requirements delay or discourage TOD, the result can be to push development to less accessible areas, leading to more driving, more emissions, and fewer housing options— undermining the very goals CEQA was meant to protect. |

| Abstract: | The Green Climate Fund (GCF) is the principal multilateral mechanism for channelling climate finance to developing countries. This paper examines the processes through which GCF projects are developed, opening the ‘black box’ of project development to better understand the uneven production of different kinds of climate finance. Empirically, the analysis addresses a puzzle in South Africa: while the Development Bank of Southern Africa (DBSA) had secured approval for three projects by 2019, it was not until 2025 that the South African National Biodiversity Institute (SANBI) secured approval for its first project. To account for this divergence, the paper brings assembling thinking into dialogue with the concept of legitimacy. A key contribution is to introduce and operationalise the ‘legitimacy machine’ to theorise how assemblages become productive. This abstract machine transforms disparate components into sufficiently legitimate entities to advance policy objectives. Legitimacy thus acts as a mechanism for establishing and strengthening connections, unlocking relational power, and enabling the flow of authority, resources, and material effects. The paper demonstrates how the production of climate finance in South Africa reflects contrasting processes of legitimacy-making in the pursuit of heterogeneous desires. DBSA rapidly mobilised private finance by legitimating the South African economy as an investible opportunity, while shielding projects from critique through decentralised delivery. SANBI, by contrast, deliberately pursued a slower, more inclusive approach – shaped by acute scarcity of adaptation finance and the political challenge of narrowing multiple project ideas without alienating ‘deserving’ publics. Its commitment to safeguarding its own institutional legitimacy outweighed the imperative of rapid approval. These findings nuance debates on the transformational potential of the GCF and its role in the top-down financialization of recipient countries. They also underscore the need for pragmatic and differentiated approaches to supporting projects, recognising that distinct forms of multilateral finance require both rapid and patient pathways. |

| Abstract: | Climate change is shifting Western US basins from snow-fed toward rain-fed systems, weakening the precision of water supply forecasts. We investigate the value of water markets in reducing economic damages from supply uncertainty. We produce hydrologic supply forecasts from data across 889 SNOTEL stations and show that forecast uncertainty is higher in rain-fed basins. We embed these empirical uncertainty measures into a water-trade model and find that when some production decisions are irreversible (e.g., planting in agriculture), and made before water availability is realized, trade helps offset losses from sub-optimal investments. We find that gains are 7\% larger in rain-fed basins on average, with offsetting effects increasing in both forecast bias and variance. As rising temperatures are expected to reduce the fraction of precipitation falling as snow, we project that water trade will become a more valuable mechanism for rationing water. |

| Abstract: | The role of institutional investors (IIs) involved in environmental issues is little studied in the literature. This article analyzes the impact of these IIs on the performance and carbon policy of a sample of 131 international banks from 39 countries. The Bayesian models tested show that institutional investors' weight in capital and their level of environmental commitment encourage banks to reduce their emissions and deploy a proactive carbon policy. The influence of this class of II is more pronounced for retail banks, the least indebted banks and those from countries with a less restrictive regulatory context. |

Les modèles Bayésiens testés montrent que le poids dans le capital et le niveau d'engagement environnemental des II incitent les banques à diminuer leurs émissions et à déployer une politique carbone proactive.

| Abstract: | study investigates drought conditions in Vietnam and its seven sub-climatic regions using the Standardized Precipitation- Evapotranspiration Index (SPEI). SPEI was derived from daily, high-resolution (10-km) precipitation and temperature products from the CMIP6-VN dataset, which statistically downscaled CMIP6 global models. Performance evaluation of 22 CMIP6-VN models confirmed their accuracy in representing precipitation and temperature characteristics for the reference period (1985–2014). Regarding the future period (2015–2099) under three Shared Socioeconomic Pathways (SSPs) (SSP1-2.6, SSP2-4.5, and SSP5-8.5), significant warming is projected across Vietnam, while precipitation projections remain uncertain, with most areas anticipated to experience slightly increased rainfall. SPEI results indicate that precipitation significantly influences drought conditions more than temperature, accounting for approximately 70% of the SPEI trend under SSP5- 8.5, which consequently introduces substantial uncertainty in drought projections. Drought conditions under different global warming levels (GWLs) were investigated, showing that while drought may not occur more frequently at high GWLs, more extreme drought events are projected. Five models exhibiting the most pronounced increasing drought trends were further analyzed, revealing a deterioration of all drought characteristics, particularly in the Northwest, Northeast, and Central Highlands. Copula statistical analysis reveals that drought events with higher return periods tend to be more prolonged and severe in the future. |

| Abstract: | In this study, we examine the influence of air pollution, measured by particulate matter concentration (PM_10 and PM_2.5), on sabotage in rank order tournaments. To achieve this, we use player-level data from German Soccer Bundesliga players between 2009 and 2024, which we link with hourly pollution values on the exact match location and kick-off time. This research design addresses key identification problems in estimating the effect of air pollution on non-health outcomes. Our results suggest that an increase in particulate matter concentration has a statistically significant effect on destructive efforts (i.e. competitive sabotage), measured in fouls committed by a player. If particulate matter pollution measured in PM_10 (PM_2.5) increases by 10 μg/m^3, the number of fouls committed increases by 0.6% (0.9%). We also find strong evidence that this effect is driven primarily by players from weaker teams (underdogs). |

| Abstract: | Madagascar, a globally recognised biodiversity hotspot, faces escalating biodiversity loss and zoonotic disease risks. Weak response systems and fragmented governance further exacerbate these threats. This study identifies key conservation and health actors and analyses their connections to understand decision-making and information flow. The findings emphasise the need to integrate One Health into conservation strategies to address interconnected public health and biodiversity challenges. Following the Laumann-Marsden-Prensky framework, a social network analysis (SNA) survey was conducted between March 14 and June 24, 2022. The study involved 30 senior leaders (≥5 years experience) in biodiversity conservation and health in Madagascar. Key network metrics, indegree, outdegree, and eigenvector centrality, identified influential actors, while network density and centralisation assessed structural cohesion. Participants listed collaborators in conservation and health projects and funding sources. The strength of One Health integration and interaction was quantified. Among 287 identified actors, 54.4 % are international entities. SNA shows that foreign organisations dominate collaboration and funding networks in conservation and public health governance, while local government bodies have limited involvement. Only a few stakeholders have effectively integrated the One Health approach into their conservation and health governance practices. These findings highlight a reliance on international actors, primarily due to funding access, with limited local participation. While international support provides crucial resources, greater national and local leadership is essential for the sustainable implementation of One Health. This study provides insights to enhance local involvement in conservation governance. |
| Abstract: | Madagascar, reconnu mondialement comme un point chaud de biodiversité, fait face à une perte croissante de biodiversité ainsi qu'à des risques accrus de maladies zoonotiques. Des systèmes de réponse faibles et une gouvernance fragmentée aggravent encore ces menaces. Cette étude identifie les principaux acteurs de la conservation et de la santé et analyse leurs connexions afin de comprendre les processus de prise de décision et les flux d'information. Les résultats soulignent la nécessité d'intégrer l'approche One Health dans les stratégies de conservation afin de répondre aux défis interconnectés de la santé publique et de la biodiversité. En suivant le cadre de Laumann-Marsden-Prensky, une enquête d'analyse de réseau social (SNA) a été menée entre le 14 mars et le 24 juin 2022. L'étude a impliqué 30 dirigeants expérimentés (≥ 5 ans d'expérience) dans les domaines de la conservation de la biodiversité et de la santé à Madagascar. Des indicateurs clés du réseau — indegree, outdegree et centralité d'eigenvecteur — ont permis d'identifier les acteurs influents, tandis que la densité et la centralisation du réseau ont servi à évaluer la cohésion structurelle. Les participants ont listé leurs collaborateurs dans les projets de conservation et de santé ainsi que leurs sources de financement. Le niveau d'intégration et d'interaction de l'approche One Health a également été quantifié. Parmi les 287 acteurs identifiés, 54, 4 % sont des entités internationales. L'analyse de réseau social montre que les organisations étrangères dominent les réseaux de collaboration et de financement dans la gouvernance de la conservation et de la santé publique, tandis que les institutions gouvernementales locales sont peu impliquées. Seul un petit nombre d'acteurs a effectivement intégré l'approche One Health dans leurs pratiques de gouvernance de la conservation et de la santé. Ces résultats mettent en évidence une forte dépendance envers les acteurs internationaux, principalement en raison de leur accès aux financements, ainsi qu'une participation locale limitée. Bien que le soutien international fournisse des ressources essentielles, un leadership national et local plus important est indispensable pour assurer la mise en œuvre durable de l'approche One Health. Cette étude offre ainsi des pistes pour renforcer l'implication locale dans la gouvernance de la conservation. |

| Abstract: | Direct Air Carbon Capture and Storage (DACCS) can mitigate hard-to-abate emissions, e.g. from transport or industry. However, there is a wide variety of cost estimates for DACCS, driven, to a significant extent, by differences in electricity cost. At the same time, there is a notable gap in research that integrates direct air capturing systems into long-term energy system models. We separate direct air capturing, carbon transport, and carbon storage and integrate them into a European capacity expansion model for a fully decarbonised electricity system in 2050. We explore how two dimensions affect the total system costs of DACCS. The first dimension is the availability of CO2 storage locations: In one analysis, storage locations are restricted to offshore storage locations in the North Sea only, i.e. depleted natural gas fields. The alternative analysis comprises suitable storage locations distributed across Europe, including onshore. We find that limiting CO2 storage to North Sea sites increases overall capture costs by approximately 10 %. The second dimension is whether DACCS is analysed as stand-alone or integrated into the electricity system. We differentiate between three alternatives: fully isolated, fully integrated, and retrospectively added to an existing system. We find that neglecting system integration - i.e. treating direct air capture system as a stand-alone technology - increases capture costs by up to 30 %. |

| Abstract: | We analyse to what extent land-related institutional settings affect the likelihood of communal violence in Sub-Saharan Africa and whether this relationship is conditioned by climate variability. Using a country–year panel covering the period 1990–2024, we focus on the occurrence of communal violence and examine the role of legal transparency and predictable enforcement of laws. The empirical analysis relies on a panel probit model for binary outcomes, controlling for socio-economic characteristics, land-use patterns, demographic pressure, and conflict persistence. The results show that higher levels of legal transparency and more predictable enforcement are consistently associated with a significantly lower likelihood of communal violence. This relationship proves robust across alternative specifications and sample restrictions. To address potential endogeneity in institutional quality, we implement a set of complementary strategies to account for unobserved heterogeneity, while exploiting early post-independence institutional conditions to mitigate concerns related to reverse causality. These checks support the robustness of the baseline association. Climate variability does not emerge as an independent driver of communal violence. Instead, drought acts as a threat multiplier by conditionally weakening the conflict-mitigating effect of legal institutions. Interaction effects indicate that while improvements in institutional quality substantially reduce the probability of communal violence under normal climatic conditions, this stabilizing effect progressively diminishes as drought severity increases and becomes negligible under severe drought. Therefore, as drought severity increases, the mitigating role of institutions progressively weakens. Overall, the findings highlight the central role of legal transparency and predictable enforcement in managing land-related tensions, while showing that their effectiveness is contingent on environmental stress. |

| Abstract: | This article measures farmers' innovativeness and the effectiveness of a priming nudge on their (stated) intention to adopt an innovation, namely the French "Low-carbon label" (LCL). The LCL is an innovative certification framework that provides farmers with a potential new "green business model, " enabling them to generate income through the sale of certified carbon credits earned by reducing their own greenhouse gas (GHG) emissions. Using 6, 005 responses to an online survey with French farmers, we validate an original scale designed to measure farmers' capacity to innovate and find that innovativeness is positively correlated with stated intention to adopt the LCL. We then evaluate with a randomized experiment included in the questionnaire the net impact of a priming nudge, defined as exposure to a lexical field designed to unconsciously activate psychological factors, and implemented here with references to innovation in order to target the most innovative farmers. We show that the nudge has no detectable impact on the surveyed sample: it neither increases adoption intentions among the most innovative farmers nor discourages the less innovative ones. This absence of effect leads us to discuss the effectiveness of nudges when trying to influence farmers' high-stakes decisions.www.agropolis-fondation.fr/?lang=en.

| Abstract: | This paper studies how increasing temperatures have affected the economies of 195 countries between 1960 and 2022, focusing on income losses caused by gradual shifts to new climate conditions. We contribute to the expanding literature on climate-macroeconomic linkages by developing a dynamic heterogeneous panel model that distinguishes between the long-term and short-term effects, accounts for adaptation through rolling climate norms, and addresses key econometric challenges including non-stationarity, cross-country heterogeneity, and unobserved global factors. Our findings reveal that a sustained 0.01°C annual increase in temperatures above historical climate norms reduces global GDP per capita growth by 0.05 percentage points per year, with income losses accumulating as long as temperatures keep increasing. This effect is 70% larger than what would be estimated under a homogeneous panel specification. Contrary to much of the existing literature, no country appears immune to the impacts of rising temperatures: middle- and high-income nations, as well as those in temperate or cold, and hot climate zones, all exhibit persistent (though not permanent) growth slowdowns, with income losses linked to how quickly they adapt. |

| Abstract: | This doctoral project explores the transition from sustainable entrepreneurship to post-growth entrepreneurship. The project builds on the premise that mainstream sustainable entrepreneurship is grounded in a weak conception of sustainability-one that proves inadequate in solving growing ecological and social crises. Degrowth, by contrast, offers a strong approach to sustainability, yet its principles remain only marginally incorporated into entrepreneurial practice. The dissertation seeks to clarify the distinctions between these two perspectives, to develop a theoretical framework for translating degrowth principles into the entrepreneurial ecosystem, and to analyze the risks associated with such a transition. Adopting a constructivist epistemological stance, the study draws on a comprehensive literature review, a systemic analytical framework, and an intervention-research project carried out with LIDEV, a sustainable-entrepreneurship support organization based in Geneva. The project thus provides value both to scholars and practitioners by generating new knowledge that can enable entrepreneurs to explore pathways toward more robust forms of sustainability. |
| Abstract: | Ce projet de thèse explore la transition de l'entrepreneuriat durable vers l'entrepreneuriat post-croissance. Il part du principe que l'entrepreneuriat durable tel qu'il est couramment compris repose sur une conception fragile de la durabilité, qui s'avère insuffisante pour résoudre les crises écologiques et sociales croissantes. La décroissance, en revanche, propose une approche solide de la durabilité, mais ses principes ne sont encore que très peu intégrés dans la pratique entrepreneuriale. La thèse vise à clarifier les distinctions entre ces deux perspectives, à développer un cadre théorique permettant de transposer les principes de la décroissance dans l'écosystème entrepreneurial, et à analyser les risques associés à une telle transition. Adoptant une position épistémologique constructiviste, cette étude s'appuie sur une revue exhaustive de la littérature, un cadre analytique systémique et un projet de recherche-intervention mené en collaboration avec LIDEV, une organisation de soutien à l'entrepreneuriat durable basée à Genève. Le projet apporte ainsi une valeur ajoutée tant aux chercheurs qu'aux praticiens en générant de nouvelles connaissances susceptibles de permettre aux entrepreneurs d'explorer des voies vers des formes plus solides de durabilité. |

| Abstract: | We quantify the effect of severe weather shocks on the US economy in an environment in which the economy can switch between periods of financial stability and financial instability, like the Great Recession. We estimate a New Keynesian dynamic stochastic general equilibrium model with banks and severe weather events. We show that severe weather shocks: 1) have a negative impact on real and financial US variables, sizable only in periods of financial instability, but muted effects on nominal variables; 2) are never a relevant source of business cycles fluctuations; 3) transmit mainly via a deterioration in the quality of capital.

| Abstract: | Non-market environmental valuation studies have incorporated and empirically examined a structured set of cognitive determinants underlying individual preferences, yet the role of affective responses remains theoretically underdeveloped. Literature suggests that incidental emotions, or mood states unrelated to the ecosystem being valued, have no significant effect on stated preferences, a null result further corroborated by ambient weather as an additional incidental trigger. Drawing on the integral/incidental distinction from the decision-making literature, we argue that this null result constitutes a boundary condition and not a general decision on the role of affect in valuation. We propose an Affective Framework, organizing eco-emotions by motivational orientation (approach versus avoidance) and semantic origin (integral versus incidental). Approach-oriented positive eco-emotions, including awe, hope, connectedness to nature, and perceived restorativeness, are predicted to amplify stated preferences. Approach-oriented negative eco-emotions, such as eco-worry, moral guilt, solastalgia, and anticipated regret, activate environmental concern and elevate willingness to pay. Avoidance-oriented eco-emotions, notably clinical eco-anxiety, despair, and eco-paralysis, suppress stated preferences by reducing perceived self-efficacy. Three mechanisms ground these predicted effects: the risk-as-feelings hypothesis, the affect heuristic, and feelings as information theory. The proposed framework offers a theoretically coherent explanation for a previously unexplained method effect in stated preference research and informs future empirical investigation. |

| Abstract: | Water is a key sector with major repercussions on health, the natural environment, and the economy. Public ownership and control of water infrastructures are the norm in most countries. Yet some private water companies emerged as early as the nineteenth century. In the last few decades, many governments, especially in developing countries, have sought the involvement of the private sector. This work contributes to the extant literature by developing a multi-disciplinary framework to look at private participation in the sector in terms of the overall trends of governments and companies' tendencies to form strategic alliances on water projects. In this study, the World Bank database on Private Participation in Infrastructure (PPI) is used and Social Network Analysis and GLM are implemented as analytical tools. This study finds that alliances between governments and companies on PPI projects are positively impacted by positional and relational embeddedness. Furthermore, governments and companies with a shared language and those that are geographically proximate are more likely to engage in PPI projects. A key policy finding is that on average, countries engaged in more PPI projects have a higher Sustainable Development Goal (SDG) 6 (Clean Water & Sanitation for All) category score. |

| Abstract: | Water security and its implications for sanitation and hygiene remain a critical global challenge and are the focus of the United Nations' Sustainable Development Goal 6 (SDG 6). Acknowledging the diversity and rapid growth of research on SDG 6—and more broadly on water and sanitation—this study conducts a science mapping analysis of the literature in this domain. The purpose of this type of analysis, in the context of a substantial and rapidly expanding body of research, is to assess the range of issues addressed within this multidisciplinary domain and to identify areas that remain underexplored or have received comparatively limited scholarly attention. Drawing on a corpus of 3, 068 articles published between 1993 and 2024 and indexed in Scopus, we applied the SPAR-4-SLR protocol to perform a thematic evolution analysis over the entire period, alongside a bibliographic coupling analysis focused on the 2020–2024 period to capture recent research trends. Both analyses were triangulated with author keyword co-occurrence analyses. In this respect, our analysis shows that several issues still lack dedicated investigation. Our findings highlight a persistent research gap in the financial dimensions of SDG 6, with limited attention to funding mechanisms for equitable and sustainable access and a fragmentation of research efforts on these issues. These results suggest that future research should prioritize innovative financing models, inclusive governance frameworks, and data-driven strategies to improve infrastructure investment and policy effectiveness, as well as stronger collaboration within the scientific community on these specific issues. |

| Abstract: | Despite extensive research linking financial inclusion to sustainable development goals (SDGs), a holistic review of this body of knowledge is still lacking. We used bibliometric methods to identify progress and gaps in this research stream to fill this gap. We propose a holistic conceptual framework of financial inclusion, decomposed into five conceptual blocks: digital and non-digital finance, financial services, and individual-level and systemic factors. The results show that current financial inclusion literature contributes mainly to 6 of the 17 SDGs, with the rest being relatively under-researched. |

| Abstract: | Cet article analyse la recomposition des systèmes de mobilité à l’ère des contraintes climatiques en articulant choix modal, équipement automobile et organisation territoriale. Il montre que le report modal est largement conditionné par les trajectoires de possession de véhicule, caractérisées par une forte inertie, et ne peut être compris indépendamment des structures urbaines. La transition vers le véhicule électrique transforme la motorisation sans réduire mécaniquement la dépendance automobile, tandis que les SERM constituent un levier central dans les zones denses. Dans les zones peu denses, les véhicules autonomes offrent des opportunités, mais comportent des risques d’effet rebond. L’article plaide pour une approche systémique intégrant instruments économiques, démographie, changement de préférences, innovations et aménagement du territoire afin d’atteindre des objectifs climatiques, d’efficacité et de bien-être social. |

| Abstract: | The global energy transition is reshaping commodity demand, yet its implications for commodity risk transmission remain unclear. We analyze connectedness among Energy Transition Metals (ETMs) – a subset of metals that are key inputs in clean energy technologies – energy commodities, and industrial metals using a Quantile Factor VAR framework. We document strong state dependence: spillovers are substantially larger in the tails of the return distribution than at the median. While crude oil remains influential, its dominance weakens post-Covid as ETMs, particularly base ETMs, gain centrality. A complementary event-study shows ETM-related policy announcements amplify spillovers in extreme regimes, indicating structural reconfiguration and systemic implications. |

| Abstract: | Forest management plans are central to regulations governing logging concessions in the Congo Basin, yet their long-term effectiveness remains uncertain. Here, we combine annual satellite-derived forest change data with administrative concession records and exploit variation in the timing of plan validation across five countries to assess how validation influences forest-cover dynamics from 2000 to 2020 using counterfactual impact-evaluation methods. We find that concessions with validated plans experience a gradual, sustained decline in forest loss, averaging 100 ± 44 hectares per year, equivalent to a 47% reduction relative to concessions operating without validated plans. Effects persist for up to 19 years and occur in concessions with and without independent third-party certification. These results indicate that accelerating the validation and implementation of forest management plans can substantially reduce forest disturbance in the Congo Basin. |

| Abstract: | Persistent economic and social inequalities constrain the inclusive development of nations. The internationally agreed Sustainable Development Goal 10 (SDG10) and its targets, aim to address these constraints through the promotion of equalising policies. This paper tests the validity of the Inequality Marker and Distributional Impact Assessment (DIA) tools that have been developed to assess the contribution of development projects to inequality reduction using as case studies four AFD and European Commission funded projects in Benin, Djibouti-Ethiopia, Uganda, and Vietnam. The DIA analyses have been carried out in two cases: in Benin (ex-post) and Uganda (ex-ante). Overall, the study shows how the Inequality Marker and DIA methodology can provide relevant information on the potential contribution of development projects to inequality reduction. The study identifies critical issues for the implementation of the DIA analysis that reflect both organisational constraints in donor agencies internal procedures, and external contextual factors. The study also provides a set of policy recommendations to mitigate these threats. |

| Abstract: | Most impact assessments of agricultural training evaluate one-time interventions over short time horizons. However, farmers may initially show enthusiasm for a new technology but subsequently dis-adopt it after a trial period, while others may adopt practices gradually over time. This study investigates the causal impact of repeated agricultural training on the adoption of organic farming practices among Indonesian smallholder farmers. Using a randomized controlled trial and four waves of panel data spanning five years, we analyze adoption dynamics over time. Farmers in the treatment group received training twice, once in 2018 and again in 2022. Our findings show that repeated training significantly increased the adoption of organic farming practices, but no evidence that training motivated farmers to fully transition to organic farming. Adoption patterns reveal substantial dis-adoption, re-adoption, and late adoption following repeated training. The results contribute to understanding longer-term adoption dynamics after extension programs and provide insights into the challenges faced by smallholder farmers transitioning to sustainable agricultural practices. |

| Abstract: | Collective action problems emerge when individual incentives and group interests are misaligned, as in the case of climate change. Individuals involved in these problems are generally considered to have two options: contribute toward public solutions such as global warming mitigation or free ride. However, many collective action problems today involve a third option of investing in a "private solution" such as local adaptation. The availability of this third option can lead to a private solution trap whereby private solutions are adopted, collectively optimal public solutions are not provided, and existing inequalities are exacerbated. We investigated the private solution trap with a collective action game featuring private and public solutions, wealth inequality determined by luck or merit, and participants from 34 countries. We found that the joint existence of private solutions and wealth inequality had a consistent effect across countries: Participants given a higher endowment adopted private solutions almost twice as often as those given a lower endowment, regardless of whether it was determined by luck or merit, and contributed proportionally less toward public solutions. Wealth inequality increased in every country and those given lower endowments were often left unprotected as public solutions were not provided. Across countries, cultural values of hierarchy and harmony were associated with preferences for private and public solutions, respectively. We also identified two universal pathways toward public solution provision: early contributions and conditional cooperation. Our findings highlight the ubiquity of the private solution trap, its cultural underpinnings, and its potential consequences for global collective action problems. |

| Abstract: | This paper develops a copula-based time-series framework for modelling sovereign credit rating activity and its dependence dynamics, with extensions incorporating climate risk. We introduce a mixed-difference transformation that maps discrete annual counts of sovereign rating actions into a continuous domain, enabling flexible copula modelling. Building on a MAG(1) copula process, we extend the framework to a MAGMAR(1, 1) specification combining moving-aggregate and autoregressive dependence, and establish consistency and asymptotic normality of the associated maximum likelihood estimators. The empirical analysis uses a multi-agency panel of sovereign ratings and country-level carbon intensity, aggregated to an annual measure of global rating activity. Results reveal strong nonlinear dependence and pronounced clustering of high-activity years, with the Gumbel MAGMAR(1, 1) specification delivering the strongest empirical performance among the models considered, while standard Markov copulas and Poisson count models perform substantially worse. Climate covariates improve marginal models but do not materially enhance dependence dynamics, suggesting limited incremental explanatory power of the chosen aggregate climate proxy. The results highlight the value of parsimonious copula-based models for sovereign migration risk and stress testing. |

| Abstract: | In 2025, the UK Government published a review of HM Treasury’s ‘Green Book’, the policy appraisal handbook used by UK public organisations in appraising, evaluating and making decisions about spending proposals to ensure value-for-money (HM Treasury, 2025a). That review highlighted several issues that required further investigation and to be addressed in the new version of the Green Book. One of these was the use of the discount rate, which needed to be reconsidered "...to make sure that the government is taking a fair view of the long-term benefits that arise from transformational investments" (ibid.). The Treasury appointed Professors Mark Freeman and Ben Groom to carry out a further review and present recommendations to the Government on the use of discount rates (HM Treasury, 2025b). Part of this review involved surveying the academic community on their views on different aspects of discount rates. CETEx submitted a response on 26 February 2026, which is presented below. |
