| Abstract: | Governments provide more than USD 800 billion annually in environmentally harmful subsidies at the global level despite international commitments. This paper introduces a novel and replicable framework for identifying biodiversity-harmful subsidies within national budgets. Our multidimensional approach is based on the five drivers of biodiversity loss: land use change, resource exploitation, climate change, pollution, and invasive species. Our framework evaluates subsidies across seven economic sectorstransport, housing, industry, agriculture, livestock, power generation, and digital deployment-based on their expected biodiversity impact (harmful, positive, mixed, neutral, or unclassifiable). We apply this framework to the French national budget and find that, in 2022, €27.14 billion were allocated to subsidize harmful activities. Pollution is the most financially supported driver of biodiversity loss. Our analysis also reveals significant trade-offs, with 25% of climate-positive subsidies exacerbating land use pressures. The study calls for a sector-specific approach to subsidy reform. By codeveloping this framework with biodiversity experts and public authorities, we provide a decision-support tool to align public investments with pathways towards sustainability. |

| Abstract: | The global food system is a significant contributor to greenhouse gas emissions that drive climate change. Animal agriculture accounts for a large share of food-system emissions, both directly and through the production of animal feed. Global population growth and rising incomes imply a further increase in demand for animal-source foods if current trends persist. Limiting global warming to the targets set by the international community will not be possible without the rapid reduction of a substantial share of animal-source foods. We show that the rapid adoption of alternatives to animal-source foods, such as plant-only diets or plant-based, cultured, or fermentation-derived analogs to animal products, can be consistent with climate goals while satisfying global demand for calories and protein. Importantly, timing is crucial: the longer the delay in adopting alternatives, the larger the share of the diet that must shift away from animal-source food by 2050 for the food system to remain within its carbon budget. |

| Abstract: | With the global emergency triggered by the oil crisis and the climate conferences initiated in the 1970s, many countries around the world found themselves compelled to seek alternatives to oil. This led, particularly in the transport sector—one of the largest consumers of oil and emitters of pollutants—to developments aimed at enabling plant-based biofuels, fleet electrification, and the use of alternative fuels, such as hydrogen. Hydrogen, which can be produced through various methods, from oil transformation to molecular water splitting, emerges as a key prospect for achieving the full decarbonization of the global economy. However, the challenges of making it widespread encounter barriers that remain difficult to overcome. Using the methodology of social network analysis, this study aims to map the main trajectory of patents involved in consolidating the processes for hydrogen production through electrolysis, specifically for applications in the transport sector—a sustainable method with potential for widespread adoption due to its high energy efficiency. The results reveal the prevalence of patents that combine electrolytic transformation with internal combustion systems reliant on fossil fuels, an outcome unexpected from a sustainability standpoint. These findings underscore the need to identify a secondary trajectory with clearer advancements toward sustainability. This research aligns with Sustainable Development Goals (SDGs) 7, 13, and 11. |

| Abstract: | This paper examines the environmental and macroeconomic impacts of changes in global value chain (GVC) participation, cross-border externality of carbon emissions, environmental considerations in monetary policy, and international coordination in environmental policy across seven NGFS scenarios. An E-DSGE model analysis shows that i) increased GVC participation, with higher reliance on imported intermediate goods, slows economic growth more significantly in high-pollution regimes, ii) the emphasis on environmental issues in monetary policy has insignificant impact on carbon emissions while increasing macroeconomic volatility to more polluted regimes. These findings suggest that while less stringent environmental policies may offer short-term benefits, these are outweighed by higher long-term transition costs. Therefore, a proactive environmental policy, aimed at achieving a 'Net Zero 2050' scenario, could foster more stable economic conditions. Furthermore, the environmental concerns in monetary policy should be moderated to mitigate potential side effects of indirect interventions on carbon emissions. |

| Abstract: | This study emphasizes the importance of green marketing in promoting sustainable economic growth, particularly through the development of green sectors like the EGGS industry. Green marketing highlights the environmental and economic benefits of such sectors, attracting investment and driving sectoral growth. By fostering consumer awareness and aligning with sustainability goals, green marketing enhances the contribution of the EGGS sector to overall economic performance. Using data from 27 primarily EU countries from 2013 to 2021 (excluding 2020 due to COVID-19?s economic impact), this analysis employs time-series regression and correlation methods to examine the relationship between EGGS contributions and GDP growth. The results show positive correlations in the majority of countries, , underscoring the role of the EGGS sector in driving sustainable growth. As economies transition toward greener practices, green marketing will be crucial in supporting sectors like EGGS, which not only contribute to GDP growth but also promote environmental sustainability. |

| Abstract: | Climate change is perhaps the most pressing challenge faced by humanity. It causes not only environmental degradation but also impacts whole ecosystems, societies, and global political stability. This paper explores the obstacles to implementing climate-change policies, emphasizing the complex interplay of economic, social, and political factors. It highlights the need to integrate economic, environmental, social, and political dimensions. It stresses that policies must be socially equitable, as demonstrated by the “Gilet Jaune” protests in France. Effective climate action requires balancing financial and non-financial factors and addressing unintended consequences such as job losses, regional economic disparities, and potential social unrest. Ultimately, a multifaceted, interdisciplinary, and inclusive approach is vital for achieving sustainable and socially responsible solutions to combat climate change |

| Abstract: | We explore the future of global climate cooperation in light of US withdrawal from global climate agreements and the reversal of US federal climate policy. At present, the free-rider problem hampers global collective action; the world needs better mechanisms to incentivize bolder climate policy. Toward this end, we suggest a heavy industry climate coalition. Countries would “join†the coalition by committing to apply a carbon fee (or an equivalent emissions trading system) to emissions-heavy industries, and they would couple that fee with a carbon border adjustment mechanism. We suggest a tiered pricing approach that would be sensitive to countries’ economic development levels to broaden coalition participation. The coalition would pair the carbon-pricing mechanism with other inducements for members, including market access, climate finance commitments, and technology transfer agreements. We estimate that a heavy industry climate coalition has the potential to reduce worldwide emissions substantially, acting as a stepping stone for further international climate cooperation. |

| Abstract: | We investigate the perceived meaning of green jobs. Theoretically, we extend the standard meaningful work framework, by introducing a social esteem component, which depends on both the green content of occupations and the socio-political awareness of environmental issues. To identify green jobs, we employ a task-based indicator based on ESCO data, which is then merged with individual-level data from the 2015 and 2021 waves of the European Working Conditions Survey. Moreover, we proxy the degree of environmental consciousness at the country level through the Environmental Policy Stringency index from the OECD. In line with our theoretical framework, we find that workers’ perceptions of meaningful work increase with the green content of their occupation and are amplified in countries exhibiting higher levels of environmental consciousness. These results highlight the role of social esteem, derived from the contribution to what is considered a socially valuable objective (i.e. the fight against climate change), in shaping the experience of meaningful work. To allow a more ‘causal’ interpretation of the results, we employ an instrumental variable approach which corroborates the main findings. |

| Abstract: | The world continues to grapple with acute hunger, malnutrition, poverty, income inequality, and other crises. In 2023, approximately 864 million people experienced severe food insecurity (FAO et al. 2024). On the one hand, poor policy adoption disrupts market and supply chain vulnerabilities, exacerbates food insecurity, and causes economic instability and crises (Hélène and Cohen 2020). On the other hand, disasters and extreme weather conditions significantly damage available infrastructure, transportation networks, and storage facilities, disrupting the distribution of agricultural commodities and as well as regular food patterns (Hasegawa et al. 2021). The COP28 UAE Declaration on Sustainable Agriculture, Resilient Food Systems, and Climate Action recognizes that agriculture and food systems must urgently adapt and transform to meet the challenges of climate change. It commits to integrating agriculture and food systems into climate action while simultaneously mainstreaming climate action across policy agendas and actions related to agriculture and food systems (UNFCCC 2023). |

| Abstract: | This article critically evaluates the role of biofuels in supporting global efforts to meet the climate mitigation goals outlined under the parties agreement. Considering that fossil fuels dramatically contributes to greenhouse gas emissions which exacerbates climate change, biofuels are a renewable and sustainable alternative. Although biofuels in itself, are not entirely precluded from environmental concerns, they remain essential in achieving emission reduction and promoting energy security. This article expatiates on the environmental benefits of biofuels and juxtaposes the technological challenges of scaling up biofuel production. It further explores the varying classification, production processes and raw materials utilized in the generation of biofuels and contends that third generation biofuels derived from microalgae is the most eco-friendly option. This Article also discusses the voluntary nature of Nationally Determined Contributions (NDCs) and how biofuels in integrated in climate strategies. It arrives at the conclusion that biofuels are significant in meeting emissions target and aligning with the global temperature goals of the Paris Agreement. |

| Abstract: | Trade’s impact on emissions is not straightforward. Existing literature on trade and emissions primarily focuses on countries' net export emissions, often neglecting the emissions saved by importing products instead of producing them domestically. The environmental impact from trade is influenced by the balance between emissions generated from exporting goods and emissions avoided by not producing them domestically. This paper investigates the environmental impacts of trade, focusing on the spatial differences in production emissions. Our estimates indicate that direct emissions embodied in exports are significant and rising, accounting for 31 percent of annual greenhouse gas (GHG) emissions and 25 percent of annual particulate matter (PM2.5) emissions in 2021. However, considering the direct emissions saved through imports, trade results in a reduction of global GHG emissions annually by up to 2.2 percent from 2004 to 2021, as it allows countries with high emission intensity to import rather than produce domestically. This reduction is not observed in PM2.5 emissions, where trade leads to an increase of up to 1 percent. These findings highlight the discrepancy in emission intensities between exporting and importing countries, which influences the impact of trade on global emissions. |

| Abstract: | The Environmental Performance Index (EPI) is a widely recognized tool developed by Yale University and Columbia University, in partnership with the World Economic Forum, to assess countries' environmental performance using 58 performance indicators across 11 issue categories. The EPI provides a comprehensive benchmark for evaluating environmental health, ecosystem vitality and climate change. Greece, as a member of the European Union (EU), operates within a complex regulatory framework aimed at promoting sustainable development. Greece's performance in the EPI reflects both its environmental policy efforts and its exposure to regional challenges such as air pollution, biodiversity loss, and climate-related risks. In recent years, Greece has demonstrated progress in areas such as renewable energy development and climate change mitigation, although issues like waste management and air quality continue to require focused policy intervention. Analyzing Greece’s EPI score offers valuable insights into its environmental priorities and the effectiveness of national strategies aimed at promoting sustainability and resilience. |

| Abstract: | The pressing need for more effective solar technology is highlighted by the global transition away from fossil fuels and toward renewable energy sources. Despite the enormous potential of photovoltaic (PV) panels, efficiency losses in high-temperature conditions limit their performance. The purpose of this study is to theoretically evaluate the energy, financial, and environmental advantages of different water-cooling techniques intended to improve the sustainability and operating efficiency of PV panels. In contrast to traditional research, this work quantifies increases in energy output, cost savings, and CO2 emission reductions across various cooling configurations by a thorough parametric analysis inside a single theoretical framework. To simulate how various water-cooling methods affect PV panel performance, a mathematical parametric model was created. Energy production, cost savings, and carbon footprint reduction were among the key performance metrics computed and compared for PV applications in relation to the consumption ratio R, which is defined as the ratio of the actual building load to the maximum PV power output, or the amount of energy consumed by the house from the PV panels. With an annual energy gain of 1354.10R kWh per panel, cost savings of 582.26R USD, and CO2 emission reductions of 785.37R kg, jet water impingement cooling (JWPV) outperformed the other technologies under evaluation. However, with energy gains of 1061.53R kWh, savings of 456.46R USD, and CO2 reductions of 615.68R kg, evaporative cooling (EPV) produced the least amount of improvement. These results highlight how important efficient cooling is to improving PV panel performance and developing sustainable solar energy solutions. |

| Abstract: | The transition to renewable energy sources is critical for addressing climate change and achieving sustainable development, especially in environmentally sensitive regions such as mountain areas. Mountains are extremely heterogeneous: they show unique features in terms of climate, topography and biodiversity, which makes them and their local populations more vulnerable to the negative effects of climate change and energy poverty. This review explores the specific challenges and opportunities associated with the implementation of renewable energies in mountain areas, with a particular focus on the Alps. It addresses the issue of energy poverty – a situation in which a household is not able to afford or is lacking access to essential energy services – and it provides a focus on the effects of climate change on mountain areas. This review also discusses the advantages and disadvantages in the potential use of various kinds of renewable energy sources in mountainous regions, including solar, wind, hydropower, and biomass; especially in the context of the Alps' unique environmental and socio-economic conditions. Despite the promising availability of these resources, some of them have not been extensively applied yet in this area, such as wind and solar power. Biomass and hydropower, on the other hand, have been largely exploited. Finally, an overview of the available energy storage systems is given, along with some practical examples of simulation or implementation of plants, highlighting the crucial role of storage and integration technologies in enhancing the reliability and efficiency of renewable energy systems in mountainous terrains. |

| Abstract: | Technological development consumes energy, depletes natural resources and generates significant carbon emissions and environmental damage (IPCC, 2023). For this reason, and in view of an effective ecological transition, it is essential that industry leaders commit themselves and steer their companies towards a development that is consistent with the challenges of sobriety. Based on qualitative research, this article aims to shed light on the contradictions between environmental objectives and sector managers' "cowboy" vision, particularly regarding their view of competition. Interviews reveal a Darwinian approach to competition, with the underlying idea that there is no monopoly. A logic of conquest, of "always more, " drives this vision. This article discusses the role of democratic institutions and legal frameworks in changing tech leaders' attitudes from a Wild West vision of unlimited resources to one of responsibility to society, especially in facing environmental challenges (Boulding 1966). |

| Abstract: | This report explores supportive measures for enhanced textile waste management in the EU-27, with a long-term perspective. It assesses the feasibility of three policy measures by describing their modalities and evaluating their implementation challenges, impacts and costs: (i) fiscal incentives (subsidies, grants, tax reductions), (ii) measures for enhanced separate collection, and (iii) mandatory information policies. In addition to a qualitative assessment, scenario analysis is applied to quantitatively assess the potential of the measures to improve the environmental impacts of textile waste management and to estimate e.g. additional investment needs for scaling up separate collection, sorting and fibre-to-fibre recycling. The overall results indicate that the investigated measures could support the transition towards a more sustainable textile waste management ecosystem, e.g., with greenhouse gas savings of up to 5.4 Mt CO2-eq yr-1 for the EU-27. Still, without addressing in parallel also the prevention of textile waste generation via production and consumption patterns, a climate-neutral and circular textiles sector will be hard to achieve. |

| Abstract: | According to a recent report by KPMG International (KPMG, 2022), the success in achieving global and national carbon neutrality targets depends largely on the decisions and actions of cities regarding climate risk management. Municipal administrations' efforts to manage carbon neutrality can have a significant ripple effect on both the population and the private sector. Unfortunately, few cities have implemented systematic processes to measure carbon emissions, primarily due to a lack of resources. A CIRANO report (Campbell et al., 2025) proposes the development of a carbon emissions dashboard that reflects the activities directly related to the management of a city. This tool could prove highly valuable for any municipal organization seeking to identify the most appropriate measures to reduce its emissions. → Read the article in PERSPECTIVES → Read the complete research report Selon un récent rapport de KPMG International (KPMG, 2022), le succès dans l’atteinte des cibles mondiales et nationales de carboneutralité repose en grande partie sur les décisions et actions des villes en matière de gestion des risques climatiques. La gestion de la carboneutralité par les administrations municipales peut avoir un effet d’entraînement important sur la population et le secteur privé en général. Malheureusement, peu de villes ont mis en place des processus systématiques de mesure des émissions de carbone, faute de ressources. Un rapport CIRANO (Campbell et coll. 2025) propose un tableau de bord des émissions de carbone qui découlent des activités propres à la gestion d’une ville. Cet outil pourrait s’avérer être d’une grande valeur pour tout organisme municipal qui désire déterminer les mesures les plus appropriées à prendre pour réduire ses émissions. → Lire l'article dans la revue PERSPECTIVES → Lire le rapport de projet complet |

| Abstract: | This paper examines weather fluctuations’ effects on subnational economic growth in Thailand (1982-2022). The identification strategy employs fixed-effects panel regressions on plausibly exogenous yearto- year weather variations within provinces, isolating local temperature’s causal effects on economic outcomes. Results reveal a statistically significant inverted-U relationship between temperature and per capita GPP growth. These adverse effects operate as persistent growth impacts, which appear more prominent in lower-income provinces, though formal statistical differences in response functions across income levels were not observed. Agriculture is highly vulnerable, while industrial and service sectors show no significant direct temperature impacts in this analysis. Integrating these estimates with RCP4.5 and RCP8.5 climate projections, future damages are widespread and severe. Without bias-correction, climate change is projected to reduce per capita output for 63-86% of Thai population, with median GDP per capita impacts from -4% to +56% (RCP4.5) and -52% to -15% (RCP8.5). However, accounting for climate model biases, even without lagged dynamics, median losses increase to 57-63% (RCP4.5) and 80-86% (RCP8.5). With lagged temperature effects, projections show substantially higher losses, leading to near-total output loss by 2090 with negligible positive likelihood. These findings highlight critical masked within-country disparities, as initial benefits in colder regions are reduced. This projection sensitivity underscores significant caveats in quantifying future economic burdens. Policy implications stress the imperative for decentralized, tailored responses leveraging granular data for highly vulnerable provinces. The persistent growth effects necessitate urgent proactive adaptation strategies, including investments in climate-resilient infrastructure, particularly for vulnerable agricultural regions. |

| Abstract: | This article examines the implementation of the EU’s circular economy policy in the electric vehicle (EV) battery supply chain, using Northvolt, a Swedish battery manufacturer, as a case study. It explores the EU’s Sustainable Batteries Regulation and its provisions for Extended Producer Responsibility (EPR) as a critical governance tool that support sustainable battery production. The article analysis Northvolt compliance with the EPR system, particularly, it’s closed-loop production model, which involves the recycling of critical raw materials from used batteries and the incorporation of these recycled materials into new battery production. The article further analyzes the participation of various actors in the EPR framework and how they contribute to the EU circular economy goals. It contends that the Northvolt case illustrates how policy compliance can drive innovation and reduce environmental impacts in the EV battery sector. |

| Abstract: | The green transition represents one of the most significant transformational forces in the labor market in the coming years. This paper analyzes the incidence of green jobs in four Latin American countries using information from job vacancy data. The results reveal a low incidence of demand for jobs with green potential or for new and emerging occupations related to the green transition. Such occupations are characterized by requiring high levels of education and offer a significant wage premium. These results highlight the main challenge of the green transition, which lies in the need to implement training processes, while revealing opportunities for the creation of high-quality jobs in the region. |

| Abstract: | Reducing the negative environmental impact of production activities without (substantial) loss of production is a crucial challenge for the agricultural sector. Investigating farms' environmental and technical efficiency (TE) levels and drivers can contribute to addressing this issue. In this regard, based on recent theoretical developments on the appropriate handling of undesirable outputs in the modeling of production technologies, this paper introduces a multi-equation stochastic frontier framework for technical and environmental efficiency (EE) analysis. This framework is applied to a sample of French suckler sheep farms. The results indicate that, on average, farms in the sample can increase their desirable output by 20% without using more inputs while reducing their greenhouse gas emissions by 24%. Findings also show that relatively high (low) levels of TE are associated with relatively low (high) levels of EE and that the likelihood for a farm to be both technically and environmentally efficient is relatively low. Only 32% of the farms in the sample have a high level of TE and EE. Drivers such as decoupled direct payments are positively associated with EE and negatively associated with TE, while no significant effect is found for green direct payments. |
| Abstract: | La réduction des impacts environnementaux négatifs des activités de production sans perte (substantielle) de production est un défi crucial pour le secteur agricole. L'étude des niveaux et des facteurs d'efficience environnementale et technique des exploitations agricoles peut contribuer à résoudre ce problème. À cet égard, sur la base de développements théoriques récents concernant le traitement approprié des outputs indésirables dans la modélisation des technologies de production, cet article introduit une approche de frontière stochastique multi-équations pour l'analyse de l'efficience technique et environnementale. Ce cadre est appliqué à un échantillon d'exploitations françaises d'élevage d'ovins allaitants. Les résultats indiquent qu'en moyenne, les exploitations de l'échantillon peuvent augmenter leur production de viande de 20 % sans utiliser davantage d'intrants, tout en réduisant leurs émissions de gaz à effet de serre de 24 %. Les résultats montrent également que des niveaux relativement élevés (faibles) d'efficience technique sont associés à des niveaux relativement faibles (élevés) d'efficience environnementale et que la probabilité qu'une exploitation soit à la fois efficiente sur le plan technique et environnemental est relativement faible. Seulement 32% des exploitations de l'échantillon ont un niveau élevé d'efficience technique et environnementale. Des facteurs tels que les paiements directs découplés sont positivement associés à l'efficience environnementale et négativement associés à l'efficience technique, tandis qu'aucun effet significatif n'est constaté pour les paiements directs verts. |

| Abstract: | This study estimates the impact of a carbon tax on welfare, considering modal shifts to less carbon-intensive transport, as well as its effects on environmental and fiscal externalities. We calibrate a modal competition model using logit demand functions for a specific long-distance connection in France and simulate the introduction of a Pigouvian tax. Our key findings are: First, a €190/tCO2 carbon tax is nearly welfare-neutral but significantly detrimental to consumer surplus; Second, rail price regulation has the side effect of reducing greenhouse gas emissions by subsidizing the cleanest transport mode; Third, the widespread adoption of electric vehicles enhances overall welfare without significantly harming consumer surplus. |

| Abstract: | As the share of renewable power generation increases, the task of power system operators to match supply and demand necessitates mobilising new flexibility sources. Among these are electrolysers, which the EU's Hydrogen Strategy for a Climate Neutral Europe envisions as power system flexibility providers. Such flexibility provision in coupled electricity-hydrogen systems has been modelled, with benefits ranging from easing RES integration [1], [2] to reaching energy transition targets at lower costs [3]. This literature however usually considers that electrolysis acts in a perfectly flexible way to minimise total system costs, usually encompassing operational costs or operational and investment costs of all multi-energy system technologies. Such flexible behaviours are idealistic, whereas electrolysers' primary goal is maximisation of their profit. Price signals are considered suitable incentives to make this happen concurrently to maximising social welfare, but this might not hold when several, conflicting incentives apply, e.g., in presence of regulation or subsidies. Hydrogen regulation has been the focus of a recent literature strand, focusing on electrolysis regulation following European and American "three pillar" typologies, enforcing the criteria of additionality, temporal correlation and geographical correlation [4]. In particular, the temporal correlation criterion for EU renewable hydrogen states that in each time period, the electrolyser plant cannot consume more electricity than its portfolio of renewable power capacities generates. These studies illustrate how such regulations affect energy system costs and emissions using a central planner modelling approach, which does not account for distorted incentives of subsidised and regulated electrolysis. Conversely, recent work illustrates how subsidies impact hydrogen dispatch decisions, and consequently energy system costs and emissions [5], without considering operation constraints from EU regulation. A case study implementing both facets illustrates the potentially strong impacts of high electrolysis subsidisation even under strict temporal correlation, but produced hydrogen quantities are endogenous and not related to an identified hydrogen demand [6]. We fill these gaps by modelling the impacts of EU renewable hydrogen support and regulation on electrolyser flexibility incentives in the planned EU 2040 energy system, and the consequence this has for power system supply-demand matching. |

| Abstract: | This article comprehensively examines the legal, institutional and procedural dimensions of Environmental Impact Assessment (EIA) framework in Nigeria. It elucidates on the progression of EIA practices from early petroleum-related regulations to the formal enactment of the Environmental Impact Assessment Act in 1992 and the subsequent 2021 Procedures and Charges Regulation. The article maps out key procedural stages of EIA, this includes the screening, scoping, documentation, decision-making, and monitoring stages. On that premise, it analyzes their effectiveness and further discusses the enforcement and oversight roles of institutions such as NESREA and FMENV in the EIA procedure and facilitating sustainable development. It further demonstrate Nigeria’s considerable alignment with global environmental standards but reveals profound concerns with the overlapping of agency functions, inadequate public participation, outdated legislation, and corporate non-compliance. The article contends that while Nigeria’s EIA framework has significant potential, effective implementation, regulatory reform, and public engagement are pertinent for realizing its environmental sustainability goals. |

| Abstract: | This paper investigates the fiscal consequences of EU-funded waste management projects on local taxation in Italian municipalities. Using a difference-in-differences approach on panel data from 2007 to 2023, we find that municipalities receiving EU cohesion funds experienced a significant increase in per-capita waste taxes, driven by rising service costs. A decomposition of these costs reveals that while separate waste collection expanded — in line with sustainability goals — the associated logistical and operational expenses increased sharply. Conversely, although the vol- ume of unsorted waste declined, disposal costs rose, likely due to lower quality and more complex treatment requirements. To assess whether cost increases reflected inefficiency or technological progress, we estimate total factor productivity changes via a non-parametric Malmquist index. The results indicate substantial productivity gains in sorted waste management, mostly from technological advancement, but also suggest transitional inefficiencies. Our findings highlight the need for more integrated investment strategies to balance environmental goals with fiscal sustainability. |

| Abstract: | Climate change can cause major challenges for Small and Medium-sized Enterprises (SMEs). Responding and adapting to such challenges is crucial, as SMEs are vital for driving economic growth and employment in most countries. Investing in R&D is a key way in which SMEs can build the capacities required for responding and adapting to climate change-related challenges. However, the extent to which such challenges affect SMEs' R&D activities remains a critical gap in existing knowledge. Using detailed firm-level data on 1, 730 SMEs in Ireland, our study is the first to explore this issue. We achieve this, using information on SMEs' climate changerelated challenges, from a new module of the 2018-2020 wave of the Irish part of the Community Innovation Survey (CIS), the Innovation in Irish Enterprises Survey (IIE). By combining a matching approach with probit regression analysis, we find that climate changerelated challenges can increase the probability of SMEs investing in R&D. Such challenges can also increase the probability of SMEs engaging in continuous, as opposed to occasional R&D. Based on our findings, the above impacts are mainly driven by climate change, resulting in higher costs/input prices. Our study highlights the importance of R&D for SMEs to adapt and respond to climate change and provides critical insights for SMEs and policymakers alike. |

| Abstract: | Urban areas accumulate heat, developing distinct urban climates that differ from the regional climate, leading to elevated mean air temperatures within cities. In tropical climates, such as Bangkok, this urban heat can contribute to high levels of heat stress. This study analyzes the spatial and temporal variation of air temperature in the Bangkok Metropolitan Administration (BMA) using dynamic climate modeling (WRF, v4.2). The analysis focuses on three distinct cli-matic periods: the cool and dry season (November–February), the hot and dry season (March–May), and the wet monsoon season (June–October). Results indicate that during sunrise in the cool and dry season, urban temperatures can be up to 6.4°C higher than those in surrounding rural areas. The highest temperature differences (>4°C) occur at night during this season, with over 50% of BMA’s urban area and population experiencing sustained exposure to these ele-vated temperatures. In contrast, the smallest temperature differences occur in the hot and dry season, despite it being the hottest overall, due to low soil moisture limiting rural cooling.

| Abstract: | Energy price shocks pose complex challenges for climate policy, combining efficiency concerns with distributional tensions. We develop a micro-founded method to estimate the behavioral and environmental effects of energy price changes, combining household expenditure microdata, a structural demand system (EASI), and supply-use tables with production-based GHG inventories. The approach enables consistent attribution of emissions to household demand and captures heterogeneous responses across income groups. Applying the method to a national case study, we simulate price shocks in electricity, heating, and transport fuels. Results reveal asymmetrical and regressive impacts, especially for essential goods with low price elasticity. Emission effects are highly dependent on substitution patterns, with some shocks triggering rebound effects. A lump-sum transfer mitigates welfare losses for electricity and heating, but not for fuels. Comparing predicted and observed aggregate responses during recent crises highlights the limits of elasticity-based instruments in practice. Our findings underscore the need for flexible, context-sensitive compensation mechanisms in carbon pricing design and illustrate a transferable method applicable across national settings. |

| Abstract: | Air pollution is a leading health risk, especially in emerging markets and developing economies. Yet, it remains unclear whether citizens will demand mitigation, perceive it as a threat, or view poor air quality as a necessary part of development. Competing theories predict either strong or weak support, and cross-national evidence is scarce, particularly for measures of policy support. We surveyed 11, 562 adults in four severely polluted cities — Accra, Delhi, Jakarta, and Johannesburg. Air quality was a highly prioritised issue, and overall levels of concern are very high. Majorities back six different mitigation proposals, including cost-salient measures such as stricter industrial limits, increasing household electrification, and expanding public transport. Concern, trust, and low behavioural control were the strongest predictors of support. People see air pollution, feel its effects, and want governments to act, even when action entails economic costs, challenging views of limited environmental demand in highly exposed, economically developing settings. |

| Abstract: | The current work examines the role of behavioural and psychology science in the design and implementation of climate policies. By synthesizing evidence from diverse disciplines, we develop an analytic framework to assess how behavioural and psychological insights can close the intention-action gap and enhance policy effectiveness. Drawing from recent studies on psychological adaptation, social norms, and policy instrument design, we argue that integrated, context-sensitive behavioural strategies can facilitate large-scale sustainable transformation. The paper emphasizes the limitations of current behavioural approaches and proposes robust, interdisciplinary policy architectures aimed at fostering equity, engagement, and long-term impact. |

| Abstract: | Climate change (CC) is a major threat to agriculture, the sector that supports the territorial economy in the Pays Haut Languedoc et Vignoble (PHLV) region (south France). In this region, farms have been facing the negative effects of CC for several decades. The implementation of agriculture adaptation policies requires a coherent and integrated tool that mobilizes approaches for territorial development, vulnerability assessments, and feasibility. The purpose of this research is to provide a multi-criteria assessment of farm vulnerability to CC in the PHLV region. An index of farm vulnerability was developed based on the classic model of vulnerability, which is the product of exposure and sensitivity divided by adaptive capacity. This assessment was conducted at the farm level, by combining biophysical variables (such as soil type and irrigation) and socioeconomic variables (such as agricultural experience and crop insurance), selected based on a literature review and interviews with local stakeholders and local experts. To solve the weighting problem, we differentiated between a "calculated vulnerability", without any specific weighting of the vulnerability variables, and a "declared vulnerability" that integrates the scores assigned to the importance of each variable for each farmer surveyed, based on their awareness. Afterward, a discriminant analysis was used to identify the factors that determine the vulnerability classes. Our results show that (i) the majority of the surveyed farms have a relatively high vulnerability index, but wine farms and cereal farms are the most vulnerable; (ii) for all farms the "declared vulnerability" is lower than the "calculated vulnerability", showing that farmers underestimate their vulnerability; (iii) there is an interesting link between the low level of vulnerability and the adaptation efforts already made over the past ten years by certain farms that have changed or introduced crops and improved their agricultural practices. |

| Abstract: | Understanding when and why nudges work is crucial for designing interventions that consistently and reliably change behaviour. This paper explores the relationship between decision-making speed and the effectiveness of two nudges – carbon footprint labelling and menu repositioning – aimed at encouraging climate-friendly food choices. Using an incentivized online randomized controlled trial with a quasi-representative sample of British consumers (N = 3, 052) ordering meals through an experimental food-delivery platform, we introduced a time-pressure mechanism to capture both fast and slow decision-making processes. Our findings suggest that menu repositioning is an effective tool for promoting climate-friendly choices when decisions are made quickly, though the effect fades when subjects have time to revise their choices. Carbon labels, in contrast, showed minimal impact overall but reduced emissions among highly educated and climate-conscious individuals when they made fast decisions. The results imply that choice architects should apply both interventions in contexts where consumers make fast decisions, such as digital platforms, canteens, or fast-food restaurants to help mitigate climate externalities. More broadly, our findings suggest that the available decision time in different contexts might at least partly explain differences in effect sizes found in previous studies of these nudges. |

| Abstract: | The last decade’s economic, social, and environmental changes have affected the production, consumption, prices, and trade of forest products in the United States. This report provides an overview of how future potential societal and biophysical changes in the U.S. South, the country, and the world may influence the region’s forest sector. Changes are modeled with six scenarios that offer alternative trajectories for socioeconomic change (rates of growth in income and population), climate warming, technology, and trade openness. Among these are two scenarios exploring (1) the accelerated adoption of mass timber products in construction, and (2) a large, hypothetical increase in trade restrictions. All scenarios are summarized in terms of changes in production, consumption, prices, and trade in forest products. Results of this study can facilitate more fully informed choices by landowners, policymakers, and industry decisionmakers as they prepare for an uncertain future. |

| Abstract: | A growing number of investors are adopting net-zero targets. Based on semi-structured interviews with 20 asset managers – primarily investing in public equities and fixed-income – this paper investigates the factors influencing target-setting. Novel to the literature, we show that investor coalitions have played a central role in the institutionalisation of net zero, including through the dissemination of ‘best practice’ guidance. However, significant variations are found in the degree to which asset managers have aligned with, or even exceeded, this guidance. To understand this heterogeneity, we propose a new typology, which distinguishes investors as hedgers, fast followers, and leaders. A combination of internal factors (such as resources and organisational values) and external pressures (including client preferences and regulatory contexts) are shown to explain these variations. Our analysis reveals that net-zero target-setting is largely a continuation of asset managers’ past responsible investment practices, shaped by their existing capabilities, beliefs, and client bases. |

| Abstract: | This paper provides evidence on the impacts of armed conflict and climate change on individual labor intensity. Based on pooled labor force survey, climate, and conflict event data from 21 African countries, we document that climate change and armed conflict can create a polycrisis: the negative impacts of extreme climate events on labor intensity in and outside of agriculture are more severe in conflict environments. This interaction effect, driven by heat waves and floods, is concentrated among young people, and it is the result of violent conflict presence before a climate event occurs, not of conflict events that occur at the same time as the climate event. In addition, our results suggest that conflict contributes to gender-specific shifts in labor allocation in response to climate events exacerbating women’s work burden. Our findings emphasize the importance of concerted, evidence-based policies to tackle climate-conflict polycrises, taking into account the specific vulnerabilities shaped by individuals’ gender and age. |

| Abstract: | The low-carbon transition is generally portrayed as involving costs to the economy through lower productivity and generating benefits through avoided impacts of climate change. This mainstream economic narrative hinges on two critical assumptions that stem from an allocation perspective: that low-carbon technologies are more expensive than high-carbon ones, and that low-carbon investment displaces resources from their optimal allocation. However, evidence increasingly suggests that neither assumption may be true. Drawing on evolutionary and complexity economics and making different, empirically-supported, assumptions about innovation dynamics, structural change, and the endogenous creation of finance, this paper examines the impacts on UK labour productivity of a low-carbon transition in the power, transport and heat sectors using a coupled macro-econometric and technology model (E3ME-FTT). Using realistic assumptions, the model results show moderate but positive productivity increases in the transition that stem from technological learning-by-doing and productivity growth in specific sectors, which induces investments that ultimately lead to expanded economic capacity across the economy. |

| Abstract: | This paper aims to reveal some discrepancies in scientific discourse related to the circular economy subtopics and to recognize some of the current and relevant shortcomings in an antagonism approach that requires more attention from scientists, policymakers, and civil organizations to reach a cohesion level between downstream and upstream measures of circular economy initiatives. These subtopics refer to the lack of basic waste management services and sanitation around the world; circular ambitions on "papers" and massive pollution in open environments; recycling and resource recovery between formal; informal, and criminal organizations; progress towards a circular economy transition and deficient waste-related statistics; Plastics Treaty between high and less ambitious countries; circular business models and greenwashing risks; smart cities and neglected rural communities. These subtopics are interlinked for circular economy discourse from local to global levels while this literature review paper reveals some pathways to overcome such societal discrepancies that act as an impediment towards a functional global circular economy. |

| Abstract: | I combine multiple rounds of geo-coded household survey data with a globally gridded climate dataset to quantify the impact of heat exposure on child disease incidence in sub-Saharan Africa. I construct hour-degree bins of temperature exposure and find that 10 additional hours of exposure to temperatures between 30–35°C in the 14 days preceding the interview increase the probability of fever, diarrhea, and acute respiratory infection by 1.5, 3.0, and 3.5 percentage points, respectively. The effects of heat are more pronounced in urban areas: exposure in the 30–35°C range raises the incidence of fever and acute respiratory infection by an additional 1.0 and 1.8 percentage points, respectively, compared to rural settings. Finally, I further find that the effects are stronger among children of less-educated mothers. These findings show the health risks posed by heat exposure in sub-Saharan Africa, and highlight the unequal burden faced by vulnerable groups. |

| Abstract: | Climate change education (CCE) is undergoing a critical transformation as global educators and policymakers recognize its role in equipping individuals and communities to respond to the climate crisis. This paper synthesizes recent scholarly developments in CCE, highlighting a shift toward participatory, interdisciplinary, and action-oriented pedagogies that foster critical thinking, adaptive capacity, and environmental agency. Drawing on research from the past five years, the paper explores the implementation of innovative teaching methods, integration across disciplines and professional training, and the growth of online and hybrid platforms. It further identifies persistent challenges such as curricular fragmentation, teacher preparedness, and equity in learner engagement, and examines evolving policy frameworks that support region-specific, justice-informed, and advocacy-focused educational strategies. Advancing CCE requires a systemic reorientation of educational policies and practices to focus on resilience, equity, and transformative action in both formal and informal learning settings. |

Data recommended for collection include those related to vehicles, infrastructure, projections, funding, the spatial location of charging power demand as a function of time, and exemptions from regulations that require fleets to purchase zero-emissions trucks and buses. These data recommendations were developed in part from conversations with staff at California agencies, such as the California Energy Commission and Air Resources Board, and with individuals working on the Alliance for Renewable Clean Hydrogen Energy Systems (ARCHES) hydrogen hub. The recommendations are evolving and could continue to evolve once data collection has begun. |

| Abstract: | France's Common Agricultural Policy Strategic Plan introduces a coupled aid program to support small-scale market gardening farms. This study, using data from a discrete choice experiment and national-level simulations, compares the projected outcomes of this new program-which has strict eligibility requirements-with those of an alternative scheme inspired by the CAP's Small Farmers Scheme (SFS), where farms self-select to receive lump-sum payments. Results indicate that the SFS+ (including environmental and employment conditions) may effectively promote agro-ecological transition in the market gardening sector and could serve as a valuable recommendation for revisions to France's strategic plan and those of other Member States.. |

| Abstract: | This article takes the bird view of the European Union Deforestation Regulation (EUDR) to rigorously evaluate the intersection of international trade law and climate governance. Although the EUDR aim to reduce global deforestation by imposing due diligence obligation on EU importers and thus determining EU market access for certain commodities, the article critiques its conformity to international trade rules, global justice and normative balance. It analyzes how environmental trade measures can bolster structural inequalities and undermine the principle of Common But Differentiated Responsibilities (CBDR). Synthesizing insights from the World Trade Organization (WTO) and normative critiques by scholars such as Luterbacher, Gupta, and Cornell, the article argues that the EUDR’s unilateral design compounded by its extra territorial effect fosters disproportionate compliance burdens on Global South exporters without procedural reciprocity or transitional support. It asserts that equitable and effective climate governance demands regulatory instruments that aligns ecological urgency with historical accountability, sensitivity to varying capacities, and inclusive participation. |

| Abstract: | Public procurement requirements and voluntary standards are increasingly used to foster environmental product innovations. However, quantitative evidence on their individual and joint effects is absent, and their conceptualization remains at an early stage. This paper makes two contributions. First, it introduces the distinction between rigid threshold and flexible benchmark uses of voluntary standards in public tenders, theorizing their opposing effects on environmental product innovations. Second, using data from 5, 127 firms in the 2021 German Innovation Survey and applying linear probability models, it provides the first quantitative analysis of their individual and joint effects across varying degrees of environmental significance. Results show that public procurement requirements and voluntary standards individually increase the probability of firms introducing environmental product innovations with high environmental significance. However, their interaction reveals a negative effect - discomplementarity - likely driven by rigid standard use, which offsets the effectiveness of procurement requirements. For environmental product innovations with low environmental significance, only voluntary standards exhibit a positive effect. These findings suggest that voluntary standards might limit the capacity of public procurement to foster more radical or disruptive environmental product innovations, while supporting more incremental innovations when used independently. |

| Abstract: | Mini-grids with a low carbon footprint are a promising solution for providing electricity in rural areas, while being compatible with the objectives of the Paris Agreement. Public policies are needed to encourage their development and their design should consider the different point of view from each stakeholder involved in mini-grid projects (State, developer, users). We propose a multi-criteria approach to evaluate a set of policies to limit the carbon footprint of mini-grids. Our method is based on the simulation of fictitious mini-grids and on the calculation of four indicators: the mitigation cost, the policy cost, the average levelized cost of energy (LCOE) at the national level, and the disparity of individual mini-grid LCOE within the country. We applied the methodology to Senegal, Madagascar, Kenya and Nigeria chosen for the diversity in solar resource and fuel price. Our results advocate for the combination of fuel tax and subsidy on solar panels and batteries to further reduce the carbon footprint of mini-grids. Using fuel tax revenues to equalize the LCOE of mini-grids within a country allows a cost-efficient reduction of the carbon footprint while reducing the cost disparities between mini-grid projects. |

| Abstract: | Long-duration energy storage (LDES) is a key component for fully renewable, sector-coupled energy systems based on wind and solar. While capacity expansion planning has begun to take into account interannual weather variability, it often ignores weather uncertainty and limited foresight in capacity and operational decisions. We build a stochastic capacity expansion model for fully decarbonized energy systems with LDES in Europe accounting for weather uncertainty - isolating the effect of limited foresight by comparing it to a perfect foresight benchmark. Under limited foresight, LDES acts as a hedge against extreme system states operating defensively and exhibiting a stockpiling effect absent under perfect foresight. Solar PV gains in system value for its higher predictability with up to 29\% higher capacities versus the benchmark while onshore wind capacities are lower. We shed light on the underlying mechanisms by deriving implicit LDES bidding curves. We show that LDES bids reflect the costs and the weather-dependent probability of extreme system states conditional on the current system state. This has important implications for the price formation on renewable electricity markets, as a wide and continuous range of probabilistic LDES bids alleviates concerns of extreme price disparity at high renewable shares. |

| Abstract: | Land consolidation is a standard policy tool to reduce land fragmentation through the spatial redistribution of property rights; however, the risk of adverse effects on the landscape raises concerns about its environmental sustainability. This study investigates the landscape impacts of consolidation on the hedgerow network of Lower Normandy, France. Implementing a staggered difference-in-differences strategy on a longitudinal survey (1972-2010), we show that consolidation led to a significant reduction in hedgerow density of -14.3m/ha (standard error: 2.33), accounting for 13.7% of the overall decline observed in consolidated areas. Our results also suggest a diminishing impact over time of consolidation and time since consolidation, an increasing impact with higher initial hedgerow density, no spillover effect, and a negative impact on network connectivity. Our findings confirm that land consolidation has significantly contributed to the decline of hedgerows, but they challenge prevailing beliefs about its share of responsibility among other factors of landscape changes. |
| Abstract: | Le remembrement est un outil politique standard pour réduire la fragmentation des terres par la redistribution spatiale des droits de propriété ; cependant, le risque d'effets négatifs sur le paysage soulève des inquiétudes quant à sa durabilité environnementale. Cette étude examine les impacts paysagers du remembrement sur le réseau de haies de Basse-Normandie, en France. En appliquant une stratégie de différences en différences échelonnées sur une enquête longitudinale (1972-2010), nous montrons que le remembrement a conduit à une réduction significative de la densité des haies de -14, 3 m/ha (erreur standard : 2, 33), ce qui représente 13, 7 % de la baisse globale observée dans les zones remembrées. Nos résultats suggèrent également un impact décroissant avec le temps de consolidation et le temps écoulé depuis la consolidation, un impact croissant avec une densité initiale de haies plus élevée, aucun effet d'entraînement, et un impact négatif sur la connectivité du réseau. Nos résultats confirment que le remembrement a contribué de manière significative au déclin des haies, mais ils remettent en question les croyances dominantes sur sa part de responsabilité parmi d'autres facteurs de changement du paysage. |

| Abstract: | Copper and lithium are essential to the global energy transition, each playing distinct roles in enabling low-carbon technologies. However, their supply chains are highly vulnerable to geopolitical risks, posing a threat to the stability and resilience of future clean energy systems. This study proposes strategic stockpiling as a cost-effective instrument to mitigate supply disruptions due to geopolitical risks in copper and lithium supply chains. First, we develop and apply novel, stage-specific, measures of geopolitical risk for copper and lithium for each of the four key phases of their supply chain: proven reserves, extraction, refining and end-use consumption. Second, we construct forward-looking stockpiling scenarios for both minerals, grounded in projected demand under the International Energy Agency’s Announced Pledges (APS) and Net Zero Scenario (NZS) pathways. Our estimates indicate substantial supply shortfalls by 2040 when strategic stockpiling is incorporated. Specifically, we project the shortfall in lithium supply to increase by a factor of 7.8 under APS and 9.8 under NZS, while copper shortages are projected to grow by 4.6 and 6.1 times, respectively. We consider Artificial Intelligence (AI)-driven productivity gains and recycling as alternative ways to alleviate shortages in both copper and lithium markets. We show that while enhanced recycling can significantly contribute to closing the supply gap for copper, its impact remains limited in the case of lithium due to technological, geological, and geographical constraints. We conclude that AI-driven productivity gains are essential to close the supply gap for both critical minerals. |

| Abstract: | This paper investigates the determinants of environmental liability insurance (ELI) market penetration in Italy. The uptake of (ELI) in Italy shows significant regional disparities, with the North and Centre having a higher level of coverage compared to the South. Only 0.45% of Italian companies had comprehensive (ELI) in 2021, and 0.64% in 2022, the year for which the most recent data are available. We show that the low uptake of ELI and the large North-South divide, lies in the uneven regulatory landscape and enforcement intensity across regions. To bridge this gap and enhance ELI adoption, comprehensive policy interventions are necessary, including uniform national enforcement of environmental regulations, expansion of mandatory insurance requirements, financial and market-based incentives for firms, educational programs to address awareness and behavioral biases, and initiatives to reduce information asymmetries. Our results for Italy, may be applicable to other countries with similar national environmental laws, market maturity of the insurance sector, and the behavioral profile of firms. |

| Abstract: | This article tackles the complex task of establishing a correlation between the volatility in gold prices and levels of unemployment, while considering the emerging influences of green economics and the green transition. We employ regression analysis, cluster analysis, time series, and Granger causality to investigate the relationship between gold prices?a traditional safe-haven asset and alternative income source?and unemployment rates, particularly during periods of economic uncertainty. As economies shift toward sustainable development, green investments are altering traditional economic dynamics, potentially affecting the role of gold as a security asset.This empirical study tracks these interactions from 2019 to 2024, using data from the EU27. This period encompasses significant economic and geopolitical challenges?including the COVID-19 crisis, military actions in Ukraine, and inflationary pressures?as well as a stronger emphasis on green transition policies. Central banks have responded by increasing interest rates, enhancing the appeal of investment assets such as bonds and gold. Meanwhile, labor markets have experienced disruptions, with evolving employment patterns due to the green transition and heightened unemployment across European countries. |

| Abstract: | The objective of the paper is to study theoretical and practical aspects of modern trends in the organic products market in Georgia and determining the prospects of its further development, develop recommendations that will support further of it development. The paper examines the organic products market, its growth trends, and the role of organic agribusiness in driving economic growth and social stability in Georgia. It highlights that the expansion of organic farming is influenced not only by global market challenges but also by the increasing interest of Georgian consumers in organic products. This growing demand is evidenced by recent market trends and the results of a consumer survey conducted by the authors.The study presents findings on Georgian consumers' attitudes toward organic products. Based on the research, the authors analyze key factors shaping the future growth of the organic market in Georgia. These include the main drivers of interest in organic food, reasons for purchasing organic products, and barriers to buying them. Additionally, the paper explores how consumers obtain information about organic products, their views on organic food consumption, their attitudes toward genetically modified foods, and their preferences between local and imported organic products. It also identifies factors that could enhance interest in purchasing domestically produced organic goods.In conclusion, the authors provide a series of scientific, practical, and organizational recommendations to promote both the production and consumption of organic products in Georgia. These recommendations aim to increase consumer adoption of organic foods, thereby fostering the sustainable development of the country?s organic farming sector, strengthening Georgian agriculture, and improving national food security?an urgent and critical issue for the country. |

| Abstract: | Irrigation and timely access to sufficient volumes of water are vital to increase crops productivity, rural incomes, and food security (FAO 2023; World Bank 2021). In Tajikistan, irrigation sector faces several challenges and constraints such as: aged, poorly maintained infrastructure and poor management system that led low-quality irrigation services; limited investment in drainage infrastructure, inadequate maintenance, poor water management, and harmful irrigation practices that led salinization and waterlogging in some irrigated areas. In addition, the ongoing process of climate change and rising temperatures will increase crop water demands, while water supply reliability will decline, leading to more-severe, more-frequent water stress. The minimum required operation and maintenance on irrigation infrastructure estimated to be about US$35 million per year. Around 85 percent of cultivated land is irrigated and provides more than 90 percent of the total value of crop production. Since independence, the condition and performance of irrigation infrastructure has declined because of severe underfinancing. More than 40 percent of irrigated areas depend on pumping (the highest dependency in Central Asia), and many high-lift, high-volume pumping stations are in poor condition. Pumping is inefficient (~0.28 kWh/m3, which accounts for 20 percent of total national electricity use). The economic productivity of irrigation is among the lowest 5 percent of countries in the world (~0.21 USD/m) because of high water loss, predominance of low-value crops, and low yields. Irrigation is heavily subsidized but still underfunded. Between 2016 and 2019, the share of public agriculture expenditure on irrigation infrastructure was high (44.6 percent or 880.3 million Tajik Somoni). Irrigation is financed through direct transfers for electricity, government subsidies for pumping station staff costs, revenue from irrigation service fees, WUA membership fees (for on-farm operations and maintenance), and donor investments. More than 60 percent of irrigation capital expenditures (including flood protection) is donor financed (Khakimov et al. 2024; World Bank. SWIM Project 2022). |

| Abstract: | Using a rich high-frequency and a cross-country panel of daily sovereign CDS spreads, we employ local projections to estimate the dynamic response of sovereign risk to the occurrence of natural disasters. We find that climatological and, to a lesser extent, hydrological events have a small and short-lived effect on the sovereign CDS spreads. We also explore whether anticipatory effects arise before a disaster unfolds, and confirm that the expectations of imminent disasters do not substantially affect CDS pricing. On the other hand, we show that the sovereign risk is dominated by regional and global financial spillovers, thus reflecting the systemic nature of the sovereign credit markets. Our results also suggest that governments may benefit from developing disaster-specific risk reduction and fiscal resilience strategies, as well as early-warning models that integrate disaster forecasting into risk monitoring frameworks. Sovereigns’ coordination and risk-pooling mechanisms may also be essential in times of regional calamities. Moreover, portfolio hedging strategies should include short-term protective positions in the vulnerable sovereigns during known disaster seasons. Disaster-integrated ESG strategies could also enhance the portfolio resilience. |

| Abstract: | There is strong evidence that exposure to atmospheric pollution is detrimental to health. However, most current and historical research has focussed on the shortrun consequences of exposure to pollution on health, and historical researchers have not been able to assess the effects of pollution on a wide range of health indicators. This paper uses fog events at a daily level as a proxy for acute extreme pollution events in historical London (1892-1919). It tests whether exposure to fog at birth and at the time of sickness influenced a wide range of indicators of child health in the short and long term, including birth outcomes (birth weight, length, stillbirth, premature birth and neonatal death), mortality risk (mortality before age 15), growth outcomes (heights and weights in infancy, childhood and adolescence), and morbidity outcomes (incidence, prevalence and sickness duration from respiratory diseases and measles). Being born on a fog day did not have strong effects on birth or growth outcomes or on morbidity outcomes for upper respiratory diseases. However, being born on a fog day increased mortality risk from respiratory diseases and increased incidence, prevalence and sickness duration from measles, influenza and other lower respiratory diseases. I also find short-run effects of fog on sickness duration from influenza and measles. Overall, the mixed results suggest that atmospheric pollution caused significant ill health in historical London but only for limited dimensions of health. |

| Abstract: | Highlights: • Seoul virus and pathogenic leptospires were detected in brown rat populations from Bamako city. • Seoul virus is prevalent in most neighborhoods of Bamako. • The distribution of leptospires varies significantly across the city. • Seoul virus strains of Bamako could result from a reassortment between two lineages. Abstract: Seoul orthohantavirus (SEOV) and pathogenic leptospires, two zoonotic agents causing similar symptoms in humans, were investigated in rat populations across several neighborhoods in Bamako, Mali. SEOV seroprevalence in brown rats (Rattus norvegicus) reached 14.8 %, while no infection was detected in black rats (Rattus rattus). Pathogenic leptospires were found in 8.7 % of brown rats, with significant inter-neighborhood variations, while only one black rat tested positive. Viral genetic analyses suggested that SEOV strains circulating in Bamako may result from a reassortment between two SEOV lineages. These findings highlight the widespread distribution of SEOV and the localized presence of pathogenic leptospires in Bamako, emphasizing the role of brown rats as reservoirs. These results can guide municipal authorities in implementing rodent control and prevention strategies to mitigate associated public health risks in Bamako. |

| Abstract: | We study Germany's photovoltaic (PV) subsidy program, estimating a dynamic model of new technology adoption which accounts for heterogeneity in residential ownership structures. We find that homeowner and landlord investors heavily discount future benefits, highlighting the suboptimality of the feed-in tariff structure and the inefficient use of government funds. The high administrative costs associated with tenant electricity contracts strongly discourage landlords from investing in new energy technologies. Our analysis suggests that policy design should prioritize upfront investment subsidies over feed-in tariffs to promote renewable energy adoption. Reducing administrative costs associated with tenant electricity programs is key to unlock investments by landlords and expand tenants' access to solar energy, thereby enhancing cost-effectiveness. |

| Abstract: | This study introduces MOVES-Matrix 4.0, an innovative high-performance implementation of MOVES 4.0.1 that generates exactly same energy and emission rate results as the Environmental Protection Agency’s latest version of MOVES 4.0.1, but allows users to deploy the MOVES model in complex and dynamic analyses. The team utilized the same conceptual design used in MOVES-Matrix 2014 and MOVES-Matrix 3.0, and updated the configurations on PACE supercomputing clusters to account for the programming changes with respect to MOVES databases (e.g., migration to MariaDB) and MOVES’ algorithm updates since MOVES2014b (e.g., extended VSP/STP parameters). The MOVES-Matrix 4.0 system develops sub-matrices of energy and emission rates by executing 181, 818 MOVES runs to generate more than 5.8 trillion energy and emission rates in thepopulated matrix for a single modeling region (represented by a unique combination of fuel specification regime and inspection and maintenance program). Performance tests demonstrate that MOVES-Matrix 4.0 produces the exact same results as MOVES4 (insignificant internal rounding errors that are less than 0.0005%). In modeling applications, generating emission rates from MOVES-Matrix is 200 times faster than running a MOVES instance. MOVES-Matrix 4.0 is ready to be used for large-scale, dynamic transportation network analyses and emissions modeling, given its open-source nature, and its compatibility with various scripting languages.

| Abstract: | Can firm-level markup adjustments affect the aggregate cost of large, localized shocks? Using firm-level data from Italy, we show that natural disasters lead to a persistent decline in markups among affected manufacturing firms, especially for high-productivity ones. We implement an oligopolistic competition model with idiosyncratic shocks directly on firm-level data and invert it to recover productivity for firms impacted by the 2012 Northern Italy earthquake. We then quantify how markup adjustments shape aggregate manufacturing productivity and welfare. Our baseline results suggest that markup changes amplified the aggregate productivity and welfare losses of the earthquake by approximately 20%. |

| Abstract: | In the context of the European path towards carbon neutrality and energy resilience, this report investigates energy poverty in EU households and energy need challenges in the EUâs building stock, focusing on the vulnerabilities and opportunities for rural areas. Based on measures of consensual comfort levels, economic strain and dwelling energy efficiency from the Household Budget Survey and the EU Statistics on Income and Living Conditions, our results indicate that rural households could face higher levels of energy poverty. A high-resolution analysis of the building stock shows that rural areas feature higher residential building volumes per inhabitant and less compact shapes, which challenges their energy efficiency and increases heating needs. On the other hand, rural areas lead in energy efficiency improvements, and are particularly suited for the implementation of self-consumption renewable systems such as rooftop photovoltaics thanks to large roof areas per inhabitant and a high share of rural ownership (78% of owned dwellings). With rooftop PV, rural areas could potentially produce 2 200 kWh/inhabitant annually, 38% more than the average household electricity consumption in the EU. |

| Abstract: | Community enterprises are often deeply embedded in local contexts, making it difficult for them to scale beyond their original setting. Recent literature suggests this challenge may also arise from intra-logic variation—differences in how “community” is defined and enacted across places. This paper builds on that insight by examining the local emergence of three types of environmental community enterprises—renewable energy cooperatives, food forests, and repair cafés—in the Netherlands. It analyzes how social, environmental, knowledge, and institutional dimensions of the community logic shape their spatial distribution. Using quantitative modeling, the study finds that each enterprise type is driven by different local conditions: social capital for RE co-ops, ecological awareness for food forests, and educational infrastructure for repair cafés. The study contributes to institutional logics theory and social enterprise literature by showing that “scaling across” varies meaningfully by type and place. |

| Abstract: | We offer evidence that federal emergency assistance (FEMA) in the days following natural disasters mitigate evictions in comparison to similar emergency scenarios where FEMA aid is not provided. We find a 16% increase in overall evictions after hurricane natural disaster events that can be decomposed to a 36% increase for those that do not receive FEMA rental assitance and only a 11% for hurricane events that do receive FEMA aid. Furthermore, we also show that FEMA aid acts as a liquidity buffer to other forms of emergency credit, specifically we find that both transactions volumes remain stable and result in a decrease in defaults by 19% in payday loans during hurricane events in locations that do receive FEMA aid. This effect largely reverses in areas that do not receive FEMA aid, where transaction volumes drop by 12\% and default rates remain similar relative to the baseline. Overall, this suggests that the availability of emergency liquidity during natural disaster events is indeed a binding constraint with real household financial consequences, in particular through our documented channel of evictions and in usage of high-cost credit. |

| Abstract: | The residential sector is one of the main consumers of energy in Nepal, with cooking being a major end-use. Unprocessed solid biomass fuels are the primary cooking fuels, with approximately 60% of households relying on them for their cooking needs. However, liquefied petroleum gas (LPG), which is entirely imported, is being widely adopted in urban areas. Electricity, which is primarily based on hydropower, a clean domestic energy source, has been used for cooking in less than one percent of households. This paper examines the cost economics of alternative technologies and fuels or their combinations for household cooking across different topographical regions in Nepal from both private and social perspectives. It finds electricity, on average, cheaper than fossil fuels but costlier than biomass fuels from a private perspective. If the costs of local air pollutants, particularly PM2.5, are considered, electricity would be the cheapest option for cooking, except for biogas, which also has minimal external costs. The study also attempts to explore the wider economic benefits of substituting imported LPG with domestic hydropower for household cooking. |

| Abstract: | Given the crucial role of Venture Capital (VC) in financing the green transition, and its uneven geographical distribution, we examine how the proximity of VC investors to green start-ups influences the success of their deals. Considering the intrinsically higher risk profile of start-ups in the greensector, we maintain that their spatial proximity to VC investors will have a larger effect here than in other sectors. Furthermore, considering recent advancements in the digitalization of VC, we also argue that a digital kind of proximity between investors and green investees in accessing digital technologies (platforms) could matter for that, by also reducing the binding effect of spatial proximity on the success of VC green deals. Using data from Dealroom, and combining them with the SpeedTest open dataset by Ookla, we test for these arguments with respect to a large sample of about 12, 000 green start-ups, originally identified by combining multiple methods (text scraping, topic modelling, and machine learning), located in 27 EU (+3) countries from 2000 to 2020. Econometric estimates at the level of realised vs. potential VC green deals confirm that spatial proximity is more relevant for green than for non-green start-ups. The new quasi- dyadic indicator of digital proximity that we propose does also significantly and positively correlates with the actual occurrence of green deals, and negatively moderate the effect of spatial proximity, supporting our argument of a substitution relationship between the two. Policy implications are drawn accordingly. |

| Abstract: | This paper evaluates the impact of higher temperatures on learning outcomes in Peru. The results suggest that 1 degree above 20°C is equivalent to 7 and 6 percent of a standard deviation of what a student learns in a year for math and reading tests, respectively. These results hold true when the main specification is changed, splitting the sample, collapsing the data at school level, and using other climate specifications. The paper aims to improve understanding of how to deal with the impacts of climate change on learning outcomes in developing countries. The evidence suggests that conditional cash transfer programs can mitigate the negative effects of higher temperatures on students’ learning outcomes in math and reading. |

| Abstract: | This study examines the relationship between AI-driven digital transformation and firm performance in Chinese industrial enterprises, with particular attention to the mediating role of green digital innovation and the moderating effects of human-AI collaboration. Using panel data from 6, 300 firm-year observations collected from CNRDS and CSMAR databases between 2015 and 2022, we employ multiple regression analysis and structural equation modeling to test our hypotheses. Our findings reveal that AI-driven digital transformation significantly enhances firm performance, with green digital innovation mediating this relationship. Furthermore, human-AI collaboration positively moderates both the direct relationship between digital transformation and firm performance and the mediating pathway through green digital innovation. The results provide valuable insights for management practice and policy formulation in the context of China's evolving industrial landscape and digital economy initiatives. This research contributes to the literature by integrating perspectives from technology management, environmental sustainability, and organizational theory to understand the complex interplay between technological adoption and business outcomes. |

| Abstract: | Les industries agroalimentaires représentent en France un poids économique important avec 19 000 entreprises et 470 000 emplois. Ce secteur joue un rôle majeur dans la valorisation de la production agricole nationale. Pour autant, il fait face à différents défis et nouveaux enjeux : une balance commerciale de plus en plus déficitaire pour une grande partie des produits, un pouvoir de négociation parfois déséquilibré, notamment pour les PME, face à la grande distribution qui est beaucoup plus concentrée, une taille réduite d'une majorité de ses entreprises qui limite leur capacité d'investissement et les rend plus sensibles aux chocs économiques (ex : prix de l'énergie), une montée en puissance des préoccupations sanitaires et environnementales. Ces constats ont été mis en évidence dans différents rapports et études au cours de la dernière décennie (ex : rapport du Sénat en 2022 1 et prospective du CGAER de 2025 2). Dans un tel contexte, l'objectif de cette journée est de présenter l'état d'avancement des recherches en sciences sociales menées au sein du département EcoSocio d'INRAE, en trois sessions (compétitivité, enjeux de durabilité et relations verticales dans les filières) et de discuter de sujets émergents lors d'une table ronde. |

| Abstract: | This study estimates an aggregate green knowledge production function (GKPF) for 19 OECD countries from 1981 to 2012, using panel-data econometric methods to address spatial spillovers and unobserved heterogeneity. Both Cobb-Douglas and translog functional forms are evaluated with multiple estimators, including standard fixed and random effects models, pooled and mean group common correlated effects (CCE) estimators, and random-trend models to account for shared upward trends among variables. The regression analysis examines the relationship between green patenting and key determinants such as R&D expenditure, human capital, and environmental policy indicators. The results consistently show a robust positive effect of domestic R&D, whereas the impacts of other factors exhibit greater variability. Methodologically, the findings highlight the sensitivity of coefficient estimates to unobserved heterogeneity and the choice of functional form. |

| Abstract: | Rebound effects from energy efficiency improvements have been widely studied over the past decades across different resources and regions using different approaches and data. This diversity has hindered comparability among studies. To date, no single study has globally estimated these effects within a common framework. This paper addresses this gap by providing estimates of direct and indirect rebound effects in 43 countries and five aggregated "rest of the world" regions using an Environmentally Extended Multiregional Input–Output (EEMRIO) model, which covers all the world. This comprehensive, data-consistent approach effectively captures spillover effects through interregional economic flows that have been overlooked in previous studies. Moreover, it improves result comparability and offers insights for previously unexamined regions. Our findings indicate that in most countries, increased energy use due to households' re-consumption surpasses expected energy savings from efficiency improvements. When the efficiencies of coal, fuel, gas, electricity and all types of energy combined improve, the proportion of countries experiencing backfire (where the rebound effect exceeds 100%) is 81.25%, 56.25%, 68.75%, 56.25% and 56.25% respectively. These results highlight the critical need to control high rebound effects to achieve reductions in global energy consumption. |

| Abstract: | Der Einsatz von Stahlschrott als Rohstoff der Stahlherstellung vermeidet Treibhausgasemissionen (THG) in erheblichem Umfang. Ambitionierte Klimaziele lassen somit einen steigenden Bedarf an Stahlschrott erwarten. Diese Studie quantifiziert plausible Bandbreiten für den Stahlschrottbedarf der deutschen Stahlindustrie bis 2045 als Zieljahr der angestrebten Klimaneutralität. Der Bedarf wird maßgeblich durch die Rohstahlproduktion, die Zusammensetzung der Verfahrensrouten sowie deren Schrotteinsatzquoten bestimmt. Um den erheblichen Unsicherheiten bei der Entwicklung dieser Faktoren Rechnung zu tragen, werden Szenarien entwickelt. Die Annahmen hinter diesen Szenarien basieren auf der Auswertung von Transformationsstudien und Trends sowie ergänzenden Annahmen. Der mögliche Stahlschrottbedarf wird für die Stichjahre 2030 und 2045 abgeleitet. Die Szenarien suggerieren, dass die Bandbreite des Stahlschrottbedarfs im Jahr 2030 zwischen 17, 0 Mio. t und 22, 7 Mio. t liegt. 2045 liegt sie zwischen 14, 9 Mio. t und 27, 6 Mio. t. Zum Vergleich: von 2015 bis 2023 wurden in Deutschland durchschnittlich 17, 2 Mio. t Stahlschrott pro Jahr eingesetzt. Der Bedarf an hochwertigem, wenig verunreinigten Schrott für die Primärproduktion von Stahl liegt 2030 zwischen 4, 3 Mio. t und 7, 7 Mio. t und 2045 zwischen 2, 7 Mio. t und 10, 1 Mio. t. Von 2015 bis 2023 wurden durchschnittlich 4, 8 Mio. t Schrott in der Hochofenroute eingesetzt. Diese Ergebnisse deuten auf einen steigenden Stahlschrottbedarf in Deutschland hin. Knappheit ist primär bei hochwertigem Schrott zu erwarten, sowohl durch einen steigenden Bedarf als auch durch eine fallende Verfügbarkeit. Technischer Fortschritt bei der Sammlung, Sortierung und Aufbereitung von Stahlschrott sowie Importe von hochwertigem Schrott könnten diese (mögliche) Knappheit reduzieren. Die tatsächliche Stahlschrottnachfrage und - knappheit wird ein Marktergebnis sein. |
| Abstract: | The use of scrap as a raw material in steel production reduces CO2 emissions substantially. Ambitious climate goals are expected to lead to an increase in demand for steel scrap, whose availability is limited. Our study (Hartung et al. 2025) quantifies the potential steel scrap demand by the German steel industry until 2045. Nine scenarios take account of the considerable uncertainties that the steel industry faces. The results show that a general shortage of steel scrap is not to be expected in Germany, but high-quality scrap specifically might be in short supply. More investment in processing and imports can reduce the shortage. |

| Abstract: | Demand for energy continues to grow, particularly in emerging economies. Like these economies, Morocco has invested significantly in renewable energies to meet the growing demand from its industry, which has been booming in recent years. The aim of this article is to examine whether an increase in renewable energy production has a positive impact on the Moroccan economy, which, like most of the world's economies, has suffered from rising oil prices and inflation following the recession, mainly due to the consequences caused by the coronavirus epidemic. The Moroccan economy, through a policy of migration or transition to renewable energies, is trying to lessen the negative effect of the recession by investing massively in renewable energies. Using data on the Moroccan economy, we test the contribution of renewable energies on the economy based on machine learning and neural networks through LSTM (LONG SHORT TERM MODELISATION) modeling. The empirical results show that an ever-increasing use of renewable energies can support the resumption of economic growth by generating a greater acceleration in GDP when compared with other variables. |

A l'instar de ces économies, le Maroc a investi de manière significative dans le domaine des énergies renouvelables pour satisfaire la demande croissante de son industrie qui est en plein essor ces dernières années. L'objectif de cet article est d'examiner si une augmentation de la production d'énergies renouvelables a un impact positif sur l'économie marocaine qui a souffert d'ailleurs comme la plupart des économies mondiales de la hausse des prix du pétrole et de l'inflation après la récession, cela est dû principalement aux conséquences causées par l'épidémie du coronavirus. L'économie marocaine, à travers une politique de migration ou de transition vers les énergies renouvelables essaie de diminuer l'effet négatif de la récession en s'investissant massivement dans les énergies renouvelables. En utilisant des données sur l'économie marocaine, nous testons la contribution des énergies renouvelables sur l'économie en se basant sur l'apprentissage automatique et le réseau des neurones par le biais de la modélisation LSTM (LONG SHORT TERM MODELISATION). Les résultats empiriques montrent qu'une utilisation toujours plus importante des énergies renouvelables peut soutenir la reprise de la croissance économique en générant une accélération plus importante du PIB en la comparant avec d'autres variables. |

| Abstract: | Preferences play a key role in decision-making and are generally assumed as time-invariant in economic modeling despite the mixed empirical evidence. We examine the stability of individual and social preferences in rural settings using the COVID-19 pandemic as a major global shock. We employ a unique longitudinal dataset comprising 1, 262 smallholder households, based on interviews with household heads conducted across four survey waves between 2019 and 2022. We find a temporal, two-year shift in risk tolerance, while interpersonal trust and generosity perceptions show a sustained deterioration over three years. We explore possible variations by household characteristics and the degree of exposure to the virus, self-confinement, and extreme weather events. |

| Abstract: | This study aimed to investigate how water scarcity and periods of drought can affect firearm homicide rates in the Brazilian semi-arid region between 2002 and 2020. To this end, the methodology of inference in counterfactual distributions proposed by Chernozhukov, Fernández-Val and Melly (2013) was employed. The main findings indicate that periods of severe drought have a significant impact on homicide rates in the semi-arid region. These effects are more pronounced when associated with factors such as the presence of rural municipalities and the migration process. In other words, there is strong evidence that drought in the hinterlands/countryside contributes to the increase in crime rates in both urban and rural municipalities. Additionally, the decomposition of the results revealed that periods of extreme drought, coupled with other unfavorable factors, act as triggers for the increase in homicide rates in the Brazilian semi-arid region, significantly exacerbating conditions of vulnerability during these adverse climatic shocks. |

Le projet AgriDinamo, piloté par l'INP-AgroToulouse, visait à caractériser ces nouveaux actifs, en s'intéressant à leur profil socio-démographique et à leur trajectoire professionnelle, mais également au projet d'installation et à l'organisation productive qu'ils portent 1 . Cette note en présente certains résultats. Elle montre que ces nouveaux actifs participent, au même titre que les autres, au renouvellement des structures agricoles. En documentant la grande diversité des projets d'entreprise et la complexité des processus d'installation, elle remet en cause l'existence d'une dualité entre exploitants issus et non issus du milieu agricole. |

| Abstract: | The transition to hydrogen powered transportation requires regionally tailored yet scalable infrastructure planning. This study presents the first Texas specific, multi-period mixed integer optimization model for hydrogen transportation from 2025 to 2050, addressing challenges in infrastructure phasing, asset coordination, and multimodal logistics. The framework introduces three innovations: (1) phased deployment with delayed investment constraints, (2) dynamic modeling of fleet aging and replacement, and (3) a clustering-based hub structure enabling adaptive two-stage hydrogen delivery. Simulations show pipeline deployment supports up to 94.8% of hydrogen flow by 2050 under high demand, reducing transport costs by 23% compared to vehicle-based systems. However, one-year construction delays reduce pipeline coverage by over 60%, shifting reliance to costlier road transport. While the study focuses on Texas, its modular design and adaptable inputs apply to other regions. It provides a tool for policy makers and stakeholders to manage hydrogen transitions under logistical and economic constraints. |

| Abstract: | Promoting recycling behavior among consumers represents a major challenge in the context of the transition to a circular economy. This study examines the impact of three levers: digital marketing, behavioral triggers and real-time feedback systems, on citizens' commitment to recycling. A quantitative approach was adopted through a structured questionnaire administered online to a sample of 320 adult participants. Data were analyzed using descriptive, correlational and regression statistics. The results show that digital marketing, in particular content disseminated via social networks, exerts a significant influence on recycling behavior. Behavioral triggers such as gamification or reminders have a moderate effect, while real-time feedback systems appear to be the least effective. The study highlights the value of combining different levers to reinforce consumers' lasting involvement in recycling practices. |

| Abstract: | Fungus-resistant grape (FRG) varieties obtained through interspecific hybridisation, are currently seen as a credible solution for reducing the use of pesticides in viticulture. One possibility is to include wines made from FRG in blends prepared from traditional varieties. Such addition is likely to negatively affect consumer's liking notably in red blends as red wines made from FRG may exhibit higher acidity, lower tannin content and stability given their high protein levels. This study aimed to apply the Consumer Rejection Threshold (CRT) method to determine to which extent red FRG wines can be incorporated into blends. Two red FRG wines, made from Vidoc and Artaban, were selected for the study and blended with a Merlot wine. After a first experiment consisting of identifying detection thresholds for FRG wines in a blend for untrained and expert panellists, a second experiment based on paired preference tests following the CRT method was conducted with consumers only. The detection thresholds were estimated for untrained subjects at 24.9 % v/v for Artaban, and 14.1 % v/v for Vidoc, highlighting a lower sensitivity than experts for which Artaban and Vidoc were detected at 6.9 % and 7.7 % v/v, respectively. During the second experiment, blends containing between 25 % and 60 % v/v of Artaban were less preferred than the single-variety Merlot wine but neutrally perceived over 60 % v/v. Surprisingly, Vidoc blends were neutrally perceived in comparison with Merlot for all the levels of incorporation evaluated, suggesting the existence of distinct clusters of consumers. Four groups of preferences were identified through Principal Component Analysis (PCA) and Hierarchical Agglomerative Clustering (HAC). Among these groups, only one representing 21 % of panellists, composed of a larger proportion of daily wine drinkers who identified themselves as novices in wine, showed a marked preference for Merlot over Vidoc blends. Overall, our results show the absence of a major sensory obstacle for the incorporation of the two studied FRG wines in Merlot blend which indicates a good consumer acceptability of these wines and encourages the wine industry to use FRG red wines for blending or in single cuvée. |

| Abstract: | Diese Studie untersucht, wie soziale Medienplattformen Tourismusmarketingstrategien, Verbraucherwahrnehmungen und Reiseverhalten beeinflussen, wobei auch die Auswirkungen auf die Nachhaltigkeit betrachtet werden. Ziel ist es, den aktuellen Stand der Forschung zu sozialen Medien im Tourismusmarketing zu evaluieren, dominante Trends zu identifizieren, empirische Belege für die Wirkung zu beurteilen und bestehende Forschungslücken kritisch hervorzuheben. Die Analyse konzentriert sich auf drei zentrale Ergebnisse im Marketing: Destinationsimage, Reiseabsicht und Nutzerengagement. Zudem beinhaltet sie einen Abschnitt über Nachhaltigkeitsaspekte, die ökologische, soziokulturelle und wirtschaftliche Dimensionen betreffen. Die Studie basiert auf einer systematischen kritischen Auswertung von 147 begutachteten wissenschaftlichen Artikeln, die zwischen 2015 und 2025 veröffentlicht wurden, sowie einer Metaanalyse von 38 quantitativen Studien, die statistische Effektgrößen berichten. Die Metaanalyse verwendet ein Random-Effects-Modell, um den Einfluss verschiedener Plattformen und Studienkontexte zu vergleichen. Moderatorvariablen sind geografische Region, Plattformtyp und methodisches Studiendesign. Die Ergebnisse zeigen, dass Marketing über soziale Medien einen statistisch signifikanten positiven Effekt auf das Destinationsimage (Cohens d = 0, 61), die Reiseabsicht (d = 0, 54) und das Nutzerengagement (d = 0, 43) hat. Die Analyse offenbart zudem geografische Verzerrungen, begrenzte Forschung zu aufstrebenden Plattformen sowie einen Mangel an Längsschnitt- und ethischen Untersuchungen. Die Ergebnisse legen nahe, dass Tourismusforscher und Marketingexperten stärker kontextsensible, interdisziplinäre und ethische Ansätze verfolgen sollten. Kritische Nachhaltigkeitsbedenken wie Übertourismus, kulturelle Kommodifizierung, digitale Ungleichheiten und algorithmische Verzerrungen treten hervor. Weitere Studien könnten sich auf spezifische plattformbezogene Verhaltensweisen, langfristige Auswirkungen und integrierte Online-Strategien konzentrieren, die der globalen Diversität im Tourismus gerecht werden. Schließlich plädiert dieser Artikel für kontextsensible, interdisziplinäre und ethisch fundierte Ansätze, um nachhaltige digitale Tourismusmarketingstrategien zu gewährleisten. |
| Abstract: | This study examines how social media platforms influence tourism marketing strategies, consumer perceptions, and travel behaviors, addressing their sustainability implications. It aims to evaluate the current state of research on social media in tourism marketing, identify dominant trends, assess empirical evidence of impact, and critically highlight research gaps. The analysis focuses on three core marketing outcomes: destination image, travel intention, and user engagement-and includes a section examining sustainability considerations across environmental, sociocultural, and economic dimensions. The study uses a systematic critical review of 147 peer-reviewed academic articles published between 2015 and 2025, combined with a meta-analysis of 38 quantitative studies that report statistical effect sizes. The meta-analysis uses a random-effects model to compare the influence of different platforms and study contexts. Moderator variables include geographic region, platform type, and methodological design. Findings show that social media marketing has a statistically significant positive effect on destination image (Cohen's d = 0.61), travel intention (d = 0.54), and user engagement (d = 0.43). The analysis also reveals geographic bias, limited research on emerging platforms, and a lack of longitudinal and ethical inquiry. Findings suggest that tourism researchers and marketers may have to adopt more contextsensitive, interdisciplinary, and ethical approaches. Critical sustainability concerns emerge, including "overtourism", cultural commodification, digital inequities, and algorithmic biases. Further studies may focus on specific platform-related behaviors, long-term impacts, and integrated online strategies appropriate for global tourism diversity. Lastly, this paper advocates for context-sensitive, interdisciplinary, and ethically grounded approaches to ensure sustainable digital tourism marketing strategies. |

El análisis también revela sesgos geográficos, investigación limitada sobre plataformas emergentes y una carencia de estudios longitudinales y éticos. Los resultados sugieren que los investigadores y profesionales del turismo deben adoptar enfoques más sensibles al contexto, interdisciplinarios y éticos. Surgen preocupaciones críticas sobre la sostenibilidad, incluyendo el "sobreturismo", la mercantilización cultural, las inequidades digitales y los sesgos algorítmicos. Futuras investigaciones podrían enfocarse en comportamientos específicos relacionados con plataformas, impactos a largo plazo y estrategias en línea integradas apropiadas para la diversidad turística global. Finalmente, este artículo aboga por enfoques sensibles al contexto, interdisciplinarios y fundamentados éticamente para asegurar estrategias sostenibles de marketing turístico digital. |
| Abstract: | Cette étude examine comment les plateformes de médias sociaux influencent les stratégies de marketing touristique, les perceptions des consommateurs et les comportements de voyage, tout en abordant leurs implications en matière de durabilité. Elle vise à évaluer l'état actuel de la recherche sur l'utilisation des médias sociaux dans le marketing touristique, à identifier les tendances dominantes, à analyser les preuves empiriques d'impact, et à mettre en évidence de manière critique les lacunes de la recherche. L'analyse se concentre sur trois résultats principaux du marketing : l'image de la destination, l'intention de voyage et l'engagement des utilisateurs, et inclut une section dédiée à l'examen des considérations de durabilité sur les dimensions environnementales, socioculturelles et économiques. L'étude est basée sur une revue critique systématique de 147 articles académiques évalués par des pairs, publiés entre 2015 et 2025, combinée à une méta-analyse de 38 études quantitatives rapportant des tailles d'effet statistiques. Cette méta-analyse utilise un modèle à effets aléatoires pour comparer l'influence des différentes plateformes et contextes d'étude. Les variables modératrices comprennent la région géographique, le type de plateforme et le design méthodologique. Les résultats montrent que le marketing sur les médias sociaux a un effet positif statistiquement significatif sur l'image de la destination (d de Cohen = 0, 61), l'intention de voyage (d = 0, 54) et l'engagement des utilisateurs (d = 0, 43). L'analyse révèle également un biais géographique, une recherche limitée sur les plateformes émergentes, ainsi qu'un manque d'études longitudinales et éthiques. Les conclusions suggèrent que les chercheurs et professionnels du tourisme devront adopter des approches plus sensibles au contexte, interdisciplinaires et éthiques. Des préoccupations critiques en matière de durabilité émergent, notamment le « surtourisme », la marchandisation culturelle, les inégalités numériques et les biais algorithmiques. Les études futures pourraient se concentrer sur des comportements spécifiques liés aux plateformes, les impacts à long terme et des stratégies en ligne intégrées adaptées à la diversité mondiale du tourisme. Enfin, cet article préconise des approches sensibles au contexte, interdisciplinaires et fondées sur l'éthique afin d'assurer des stratégies durables de marketing touristique numérique. |
| Abstract: | Questo studio esamina come le piattaforme di social media influenzino le strategie di marketing turistico, le percezioni dei consumatori e i comportamenti di viaggio, affrontando anche le implicazioni relative alla sostenibilità. L'obiettivo è valutare lo stato attuale della ricerca sui social media nel marketing turistico, identificare le tendenze dominanti, analizzare le evidenze empiriche degli impatti e sottolineare criticamente le lacune della ricerca. L'analisi si concentra su tre principali risultati di marketing: l'immagine della destinazione, l'intenzione di viaggio e il coinvolgimento degli utenti, e include una sezione dedicata alle considerazioni sulla sostenibilità in ambito ambientale, socioculturale ed economico. Lo studio utilizza una revisione sistematica critica di 147 articoli accademici sottoposti a revisione tra pari, pubblicati tra il 2015 e il 2025, combinata con una meta-analisi di 38 studi quantitativi che riportano dimensioni statistiche dell'effetto. La meta-analisi impiega un modello a effetti casuali per confrontare l'influenza di diverse piattaforme e contesti di studio. Le variabili moderatrici comprendono la regione geografica, il tipo di piattaforma e il design metodologico. I risultati mostrano che il marketing tramite social media ha un effetto positivo statisticamente significativo sull'immagine della destinazione (d di Cohen = 0, 61), sull'intenzione di viaggio (d = 0, 54) e sul coinvolgimento degli utenti (d = 0, 43). L'analisi rivela inoltre un bias geografico, una ricerca limitata sulle piattaforme emergenti e una carenza di studi longitudinali ed etici. I risultati suggeriscono che i ricercatori e gli operatori del turismo debbano adottare approcci più sensibili al contesto, interdisciplinari ed etici. Emergono preoccupazioni critiche relative alla sostenibilità, tra cui il "sovraturismo", la mercificazione culturale, le disuguaglianze digitali e i pregiudizi algoritmici. Ulteriori studi potrebbero concentrarsi su comportamenti specifici legati alle piattaforme, impatti a lungo termine e strategie integrate online adatte alla diversità turistica globale. Infine, questo documento sostiene approcci sensibili al contesto, interdisciplinari e basati sull'etica per garantire strategie di marketing turistico digitale sostenibili. |

| Abstract: | In response to the escalating need for sustainable manufacturing, this study introduces a Simulation-Based Approach (SBA) to model a stopping policy for energy-intensive stochastic production systems, developed and tested in a real-world industrial context. The case company - an energy-intensive lead-acid battery manufacturer - faces significant process uncertainty in its heat-treatment operations, making static planning inefficient. To evaluate a potential sensor-based solution, the SBA leverages simulated sensor data (using a Markovian model) to iteratively refine Bayesian energy estimates and dynamically adjust batch-specific processing times. A full-factorial numerical simulation, mirroring the company's 2024 heat-treatment process, evaluates the SBA's energy reduction potential, configuration robustness, and sensitivity to process uncertainty and sensor distortion. Results are benchmarked against three planning scenarios: (1) Optimized Planned Processing Times (OPT); (2) the company's Current Baseline Practice; and (3) an Ideal Scenario with perfectly known energy requirements. SBA significantly outperforms OPT across all tested environments and in some cases even performs statistically equivalent to an Ideal Scenario. Compared to the Current Baseline Practice, energy input is reduced by 14-25%, depending on uncertainty and sensor accuracy. A Pareto analysis further highlights SBA's ability to balance energy and inspection-labour costs, offering actionable insights for industrial decision-makers. |

| Abstract: | Using longitudinal, nationally representative data from Australia, this study uncovers a previously undocumented pattern: in over half of cases where one household member reports weather-related home damage, their co-resident does not. This high rate of intra-household inconsistency is striking, particularly given that respondents are asked the same question within a similar timeframe, and that prior research has generally treated self-reported damage as exogenous to individual behaviour. Household fixed-effects models indicate that a range of factors, including individual health, life satisfaction, local socio-economic conditions, and cyclone exposure, are systematically associated with both the likelihood of reporting damage and intra-household inconsistencies. Individuals in better health, with higher life satisfaction, or residing in more advantaged areas are less likely to report damage—whether consistently or inconsistently—relative to their household member. Furthermore, replacing self-reported damage with a more objective measure substantially attenuates the observed associations between damage and individual health and life satisfaction. Taken together, these findings challenge the common assumption of exogeneity in self-reported weather-related home damage and underscore the risk of biased inference if endogeneity is not adequately addressed. |

| Abstract: | Monitoring income distribution in the bioeconomy and food system is necessary to understand their contributions to socioeconomic development and inform related policies. This report proposes a set of replicable methodologies for the inclusion of income distribution indicators within the frameworks of the Bioeconomy Monitoring System (BMS) and the EU Food System Monitoring Framework (FSMF). The report develops four indicators to measure income distribution in the bioeconomy and food system sectors, focusing on the functional income distribution. The indicators include the average salary by sector, share of labour income over value added, employee' earnings ratio, and share of value added by sector in the food chain. The report applies these indicators to the EU bioeconomy and food system sectors, revealing significant divergences in income distribution across sectors and Member States. |

| Abstract: | El agravamiento de las problemáticas ambientales, sociales y económicas asociadas al uso de combustibles fósiles intensifica la urgencia de una transición hacia fuentes de energía renovables, impulsando la adopción de tecnologías como paneles solares, turbinas eólicas y vehículos eléctricos. Aunque frecuentemente promovidas como soluciones sostenibles, estas tecnologías presentan características intrínsecas - como menor densidad energética, vida útil reducida y limitaciones en los procesos de reciclaje - que incrementan la dependencia de minerales, muchos de ellos clasificados como “críticos”. Este artículo busca contribuir al debate mediante el análisis de los impactos del aumento significativo en la demanda de estos recursos. Con base en la definición de minerales críticos de la Agencia Internacional de Energías Renovables - que incluye cobalto, níquel, cobre, litio y metales de tierras raras -, se realizó una amplia recopilación, sistematización y análisis de datos a escala global, identificando los principales países productores y los contextos socioambientales asociados a su extracción. Los resultados evidencian la reproducción de un patrón histórico: la mayor parte de estos minerales se extrae en países del Sur Global, especialmente en África, Asia y América Latina, donde las normativas ambientales, sociales y económicas tienden a ser más flexibles, favoreciendo a grandes corporaciones transnacionales. Se constató, además, que la extracción de estos minerales suele estar asociada a impactos socioambientales graves, como contaminación intensa, exposición de trabajadores a metales tóxicos y financiamiento de milicias vinculadas a regímenes autoritarios. Estas cuestiones, aún poco discutidas en el discurso dominante sobre la temática, requieren una mayor atención por parte de la comunidad científica y de la sociedad en general, a fin de promover una transición energética verdaderamente justa a escala global. |

| Abstract: | Fish farming in Côte d'Ivoire has been promoted as a diversification strategy for cocoa producers, yet the sector exhibits significant heterogeneity in farming practices, which remains poorly documented. This study aimed to classify fish farming systems and identify key determinants of their performance. Surveys were conducted with 45 farmers across three cocoa-producing regions - Bédiala, Méagui, and Sinfra - and data were analyzed using Factor Analysis of Mixed Data (FAMD) and clustering analysis, leading to the identification of three distinct farm types. Type 1 farms, found in Bédiala, have the largest production areas (median: 2.9 ha) and predominantly practice polyculture of Nile tilapia (Oreochromis niloticus), bony tongue (Heterotis niloticus), and catfish (Clarias spp.), often integrated with rice farming. Type 2 farms, found in Sinfra, employ the most intensive practices, characterized by the use of monosex tilapia fingerlings and reproductive control via banded jewelfish (Hemichromis fasciatus), resulting in the highest yields (median: 1, 033 kg ha⁻¹ yr⁻¹). Type 3 farms, found in Méagui and Sinfra, are the least productive (median: 450 kg ha⁻¹ yr⁻¹), constrained by longer production cycles and limited technological adoption. These findings reveal significant regional disparities in fish farming practices and productivity, underscoring the need for tailored policy interventions. Strategies should focus on promoting improved production techniques in low-yielding systems while supporting sustainable intensification in more advanced farms to enhance the sector's contribution to rural livelihoods and food security. |

| Abstract: | A persistent puzzle in developing economies is why rural households remain in low-productivity agricultural sectors despite the substantial income gaps with non-agricultural opportunities. While existing studies attribute this gap to market frictions, institutional barriers, and differences in human capital, this paper shifts the focus to household-level welfare trade-offs, specifically, the non-pecuniary welfare losses borne by family members left behind when working-age individuals migrate. We develop a theoretical framework to show how such hidden costs affect labor reallocation and how they can be quantified empirically. Leveraging China's Grain for Green (GFG) Program--a nationwide conservation policy that induced farmland retirement in exchange for subsidies, we show that the policy led to significant increases in migration and non-agricultural labor, especially among women and younger individuals. Using revealed preference logic, we estimate that hidden migration costs amount to 10.5--12.6% of total household income for policy-induced migrants. Drawing on rich survey data, we trace these costs to two key sources: disruptions to children's education and reduced caregiving capacity for elderly household members. These findings highlight the need for policies that ease the burden of migrating with dependents, such as removing restrictions on education and healthcare access in destination areas. |

| Abstract: | Selon la Commission européenne, les pays européens sont responsables de plus du tiers de la déforestation liée au commerce international de produits agricoles. De même, les défenseurs des droits humains considèrent les entreprises multinationales dont le siège est en Europe, responsables de violations des droits humains qui sont commis par leurs fournisseurs tout le long de leurs chaines d'approvisionnement. L'Union européenne porte donc, une responsabilité importante justifiant un engagement exemplaire et réglementaire. Grâce à une enquête de terrain menée dans le secteur de la banane, du café et du cacao, nous montrons comment les standards de deuxième génération (Max Havelaar et Rainforest Alliance) travaillent étroitement avec les entreprises agroalimentaires afin de les préparer – ou pas – aux exigences des nouvelles réglementations. |

| Abstract: | Current paper, introduces Deucalion, a dynamic dataset currently consisted of 5, 042 photos from Instagram, which was scraped for researching on the medicane Ianos during September 2020, and two Kaggle sources with flood related content. Other sources, including internet search engines and Flickr complete the data provider list of current version. 1, 664 photos of them were imported in LabelStudio and objects were identified and digitized. The objects extracted are currently classified in 15 different classes, including flood, sea, pools, rocks and mud, vegetation. The entire dataset was used for fine-tuning a vgg19, providing thus SOTA metrics, while various classes of the 1, 664 subset were used to train a YOLO model. The plethora of different classes and sources, the real world captures, along with the dynamic nature of Deucalion is expected to emerge it as a significant research dataset. The dataset currently can be available upon request. |

| Abstract: | Paraguay's economic activity remains robust, bolstered by ongoing reforms and sound macroeconomic fundamentals. Inflation is within the central bank’s tolerance range, and both public debt and the external position are sustainable. While the outlook is favorable, it remains subject to elevated global risks and vulnerable to adverse weather shocks. The authorities have reaffirmed their strong commitment to the fiscal consolidation plan—an essential anchor of macroeconomic stability. Paraguay’s sovereign debt trades with one of the lowest risk spreads in the region. |
