The study evaluates the impacts of sugarcane and jatropha biofuels in sub-Saharan Africa, finding that while sugarcane offers carbon-sequestration benefits and positive socioeconomic impacts for workers, jatropha failed to benefit local communities due to market collapse and low yields. Additionally, the adoption of household ethanol stoves in Maputo was hindered by high costs.

The guide uses a series of realistic, simulated scenarios to explore the complexities of involving citizens in sustainable energy projects, such as wind farm siting and energy efficiency upgrades. It focuses on three primary dimensions of success: social legitimacy, institutional sustainability, and political effectiveness. Through 39 different sections, the document analyzes the trade-offs between different engagement models—participatory, deliberative, and hybrid—and provides strategies for managing conflicts, handling technical constraints, and navigating the influence of higher-level government bodies and political election cycles.

The report analyzes the HYBRIT process, which replaces coal with hydrogen for the direct reduction of iron ore combined with an electric arc furnace to create fossil-free steel. While technically feasible and potentially cost-competitive depending on electricity and carbon prices, the transition faces systemic barriers including high investment risks, the need for large-scale electrolysis infrastructure, and the risk of carbon leakage in a globally competitive market.

A systematic review of 244 studies on prescribed burning in temperate and boreal forests found significant positive effects on vascular plant richness and herbaceous plant richness in broadleaf forests, though outcomes remain difficult to predict and may harm conservation-dependent taxa.

The document highlights the high climate risk in Southeast Asia and specifically Northern Thailand, where agricultural productivity is threatened by temperature shifts and precipitation changes. It argues that vulnerability is disproportionately higher for specific groups, including women and girls, and seeks to fill a research gap regarding how age, gender, poverty, and ethnicity intersect to shape the climate challenges faced by young women and girls in this region.

SEI scientists Peter Erickson and Michael Lazarus argue that limiting fossil fuel supply, specifically high-cost and high-emissions oil in California, is essential for solving the climate crisis. They contend that reducing production helps avoid stranded assets and that California's projected decrease in oil demand by 2030 allows for a production phase-down without increasing oil imports.

The paper examines transparency as a site of political conflict, arguing that while transparency is often seen as a tool for improving environmental outcomes, it can be used to avoid strict regulation. Using a new theoretical framework, the authors analyze climate finance under the Paris Agreement, finding that strong transparency norms have not translated into effective accountability mechanisms or donor compliance, meaning transparency alone is insufficient for an equitable climate policy regime.

The study estimates that tropospheric ozone significantly reduces global yields for soybean, wheat, rice, and maize, with the highest losses occurring in regions already stressed by pests, heat, and nutrient deficiencies. It advocates for integrating ozone tolerance into crop breeding programmes and altering management approaches to close the 'ozone yield gap'.

The report examines water security in Burkina Faso's Nouaho sub-basin, finding that climate-exacerbated hazards like water scarcity and flooding disproportionately affect women and girls due to gendered divisions of labour and social norms. While women primarily manage domestic water collection and often lead off-farm income activities, they are largely excluded from community-level decision-making and water association leadership. The document argues that WASH adaptation must move beyond technical infrastructure to address gender discrimination and empower marginalized groups to ensure long-term water security.

The briefing proposes using border carbon adjustments (BCAs) to levy carbon charges on imports, thereby creating a level emissions playing field between domestic and external manufacturers and incentivizing trade partners to adopt low-carbon products.

The document asserts that reducing fossil fuel supply is essential to keeping global warming well below 2°C, despite the Paris Agreement's silence on the matter. It suggests that countries can use existing Paris Agreement architecture and mechanisms to articulate and report actions aimed at curtailing fossil fuel supply, which would enhance the ambition and effectiveness of climate mitigation efforts.

The authors developed a global index of exposure to transnational climate impacts to address the limitation of classic vulnerability indices, which typically focus on national or local estimates and ignore cross-border effects. The findings show that while internal climate risks correlate strongly with geography and economic development, exposure to transnational impacts follows a more complex distribution that cannot be explained by these factors alone. The paper argues that robust adaptation planning requires risk assessments to incorporate both transboundary and far-reaching teleconnected interdependencies.

The document introduces a study that applies the Planetary Boundaries framework—which sets quantitative limits on human perturbation of Earth system processes to avoid irreversible environmental change—to the EU-28. It specifically focuses on disaggregating and benchmarking boundaries for climate change, biosphere integrity, land systems change, freshwater use, biogeochemical flows, and novel entities.

The report examines the climate footprint of Swedish public sector consumption, highlighting that municipal activities account for approximately 70% of public consumption-based emissions. Through case studies of Eskilstuna and Umeå, the document analyzes quantitative, qualitative, and transformative measures to reduce emissions from food and transport. Key findings indicate that while administrative and informative tools are common, more powerful transformative changes—such as establishing vegetarian norms and urban densification—are necessary to meet long-term climate goals. The report recommends that Sweden establish consumption-based emission targets for 2030 and 2045 to complement territorial goals.

The paper demonstrates the application of Sida's Multidimensional Poverty Analysis (MDPA) framework within the Water Evaluation And Planning (WEAP) tool to identify inequalities in water access and land distribution in Colombia's Campoalegre Watershed. Findings reveal significant data gaps for rural areas, infrastructure capacity shortages in urban centres, and a strong correlation between small landholdings (microfundios) and an inability to meet basic food needs.

The document assesses Colombia's vulnerability as the world's fourth largest thermal coal exporter facing declining global demand. It highlights significant risks to regional GDP and employment in the Cesar and La Guajira departments, where coal is a dominant economic driver. The brief notes a lack of domestic planning for post-coal scenarios and evaluates alternatives such as agriculture and tourism, while recommending coordinated long-term planning involving national institutions like the DNP and UPME to ensure a just transition.

The document examines the risks Colombia faces as a major coal exporter amid falling global demand and the rise of renewables. It highlights the extreme vulnerability of the Cesar and La Guajira departments, where coal is a dominant driver of regional GDP and employment. The brief argues that Colombia currently lacks a formal national or regional plan for a post-coal transition, leaving it susceptible to economic instability, unemployment, and social unrest. It recommends long-term planning led by the DNP and UPME, diversification into agriculture and tourism, and the implementation of a 'just transition' framework to protect workers and the environment.

The Tropospheric Ozone Assessment Report (TOAR-Vegetation) analyzed ozone metrics across over 3,300 vegetated sites globally, focusing on M12, AOT40, and W126. Findings indicate that the highest ozone values (2010–14) are concentrated in the mid-latitudes of the northern hemisphere, while the lowest are found in parts of Australia, New Zealand, South America, Europe, Canada, and the USA. Between 1995 and 2014, ozone trends showed a significant decrease in North America, no change in Europe, and a significant increase in East Asia. The report recommends expanding ozone monitoring, investigating peri-urban and mountain agriculture, and establishing region-specific damage thresholds.

The study examines a 60 kW solar mini-grid in Mpanta, Zambia, finding that a lack of local socioeconomic integration and poor expectation management have hindered the transition from traditional fuels to modern energy services.

The BONUS RETURN project launched the Nutrients and Carbon Reuse Challenge in December 2017 to identify eco-technologies capable of transforming nutrients and carbon into benefits. Out of 13 applications, three winners—Biophree, TerraNovaUltra, and Ravita—were selected based on criteria including relevance, sustainability, and market potential. These technologies focus on recovering phosphorus and carbon from wastewater and agricultural sectors to support the Baltic Sea Region's environmental goals.
