The document outlines the interconnected nature of the climate crisis, biodiversity loss, and social injustice, arguing that current economic systems based on fossil fuels and mass consumption are unsustainable. It provides specific data on water scarcity, air pollution, and ecosystem collapse while advocating for a transition to clean energy, regenerative agriculture, and circular economies to protect the planet and its most vulnerable populations.

The document argues that the current ecological crisis—characterized by climate change, biodiversity loss, and pollution—is rooted in overconsumption and fossil-fuel-based economic systems. It calls for a transition toward circular economies, regenerative agriculture, and a 'just transition' that prioritizes the rights of the poor, indigenous peoples, and future generations.

The report examines the fragmented state of Green Public Procurement (GPP) within the EU and proposes recommendations to leverage public purchasing power for decarbonization. Focusing on the construction and road transport sectors—which each account for approximately 12% of government procurement GHG emissions globally—the study analyzes case studies from eight EU Member States to identify best practices for meeting the EU's goal of a 55% reduction in GHG emissions by 2030.

The authors examine how legitimacy is used as a tool for political contestation in the governance of transboundary climate risks (TCRs). By analyzing 41 interviews within the Brazilian-German coffee supply-chain, the paper identifies five distinct governance pathways, each based on a different operationalization of legitimacy. The authors argue that legitimacy is not a static quality but an object of contestation that actors use to promote their preferred governance approaches and delegitimize others, a dynamic they suggest is applicable to broader challenges in global environmental governance.

The report outlines the second phase of a project by the Climate Solutions Accelerator of the Genesee-Finger Lakes Region and the Stockholm Environment Institute to identify emission reduction pathways. It builds upon a baseline emissions assessment of the region's counties to evaluate long-term mitigation potential, aiming to produce a final Climate Action Strategy with specific targets and measures.

The document examines the gap between EU Green Public Procurement (GPP) targets and actual implementation in eight Member States. It identifies systemic barriers—including fragmented governance, lack of standardized data, and limited procurement officer capacity—while highlighting successful local and national initiatives in Sweden, France, Germany, and others. The brief argues that the EU must harmonize reporting, institute mandatory requirements for high-emitting sectors, and provide better technical support to leverage public spending for climate goals.

The analysis finds that interactions between key SDG targets are generally synergetic at a global level under a 1.5°C warming limit, with climate finance and policy mainstreaming acting as primary accelerators for other goals.

The Stockholm Environment Institute has developed WASH Flows, a Microsoft Excel-based tool that links household-level WASH data with watershed-scale modelling, such as WEAP. By bridging the gap between WASH services and Integrated Water Resource Management (IWRM), the tool allows users to estimate service levels, identify vulnerable communities, and model the impact of interventions on water balance and quality. A case study in the Tupiza watershed in Bolivia demonstrated the tool's ability to establish a service baseline—revealing significant gaps in safely managed water (25%) and sanitation (4%)—and to evaluate the effectiveness of proposed drinking water and decentralized sanitation systems in increasing drought resilience.

The Mekong Thought Leadership and Think Tanks Network is a three-year initiative supported by the Australian Government's Department of Foreign Affairs and Trade (DFAT). It aims to improve water and energy security and climate resilience in the Mekong Subregion by strengthening the capacity of knowledge-based policy influence organisations (KBPIOs). The program focuses on inclusive knowledge co-production and the engagement of vulnerable and marginalised groups. It is managed by a consortium of eight organisations led by the Stockholm Environment Institute - Asia Centre. The program funds flagship studies (up to AUD 250,000) and rapid response projects (up to AUD 50,000) addressing specific issues such as transboundary water disaster risks, urban heat resilience, and gender-sensitizing infrastructure in the Mekong Delta.

The report examines the intersection of digitalization and sustainability at Urban Deli, a Swedish food retailer. Despite a strong organizational sustainability vision, the study finds that digital tools are currently used primarily for operational efficiency and cost reduction rather than for sustainability decision-making. Key barriers include a lack of standardized environmental data, supplier reluctance to share detailed information, and internal challenges regarding the capability to interpret and act on sustainability data. The findings suggest that increased information alone is insufficient without organizational prioritization and a supportive regulatory framework.

The report finds that Green Public Procurement (GPP) in the EU is characterized by a fragmented approach with few binding requirements and significant gaps between national climate targets and actual procurement practices. While some regions like Catalonia and cities like Berlin show high ambition, most Member States rely on voluntary guidelines. The construction and road transport sectors are highlighted as high-impact areas where GPP could drive decarbonization, yet implementation is hindered by a lack of standardized data, insufficient capacity and time for procurement officers, and a lack of mandatory EU-level criteria. The report recommends harmonizing GPP definitions, introducing mandatory carbon criteria, and expanding the scope of EU Directives to include embedded emissions.

The LUCI tool provides a five-step analytical framework to identify unintended consequences of development interventions by mapping the overlap between identity groups and impact groups. It emphasizes 'horizontal inequalities'—group-based disparities related to gender, ethnicity, or class—and how these can be exacerbated by poorly planned projects, leading to 'maladaptation' or increased conflict potential. The guide demonstrates the tool's application through a case study of solar hybrid mini-grid projects in Turkana County, Kenya, illustrating how access to electricity can create differential benefits and losses across various social and economic groups.

The research analyzes how climate-induced crop yield changes between 2070 and 2099 may disrupt global food trade networks for wheat, rice, and maize. Using a network model, the study finds that maize trade is the least stable of the three crops and suggests that global food security will depend on production changes in major producers and the ability of trade communities to balance losses in vulnerable countries.

The paper analyzes the impact of Costa Rica's decarbonization plan on short-lived climate pollutants (SLCPs), specifically black carbon and methane. It estimates significant emission reductions by 2050 across the transport, agricultural, solid waste, and industrial sectors, while identifying financial and governance barriers. To address these, the authors propose cross-sectoral synergies including environmental tax reform, updated urban regulatory plans, strengthened institutional capabilities, and favorable low-carbon financing.

The study finds that policy attention to Short-Lived Climate Pollutants (SLCPs) and air pollutants in NDCs increased significantly between pre- and post-2020 submissions, with a doubling of explicit references to these pollutants as priorities and a 45% increase in specific mitigation measures.

The document examines the health risks associated with charcoal grilling in Vientiane, Lao PDR, finding that workers—particularly women—face high levels of PM2.5 exposure. It highlights a lack of social protections in the informal food economy and recommends multi-sectoral collaboration to improve ventilation, promote clean fuels, and formalize labor contracts.

The report evaluates three emissions scenarios for the Genesee-Finger Lakes Region: an existing policy scenario, a low ambition scenario, and a high ambition scenario. It finds that while the high ambition scenario can meet the 2030 intermediate target of the CLCPA, none of the current scenarios are sufficient to meet the 85% reduction goal by 2050. Key challenges include high emissions from enteric fermentation in dairy cows and methane leakage from large landfills. The analysis emphasizes the need for a carbon-free grid, electrification of transport and heating, and enhanced agricultural manure management.

The report introduces a technology-neutral sustainability assessment method based on five pillars: social, environmental, economic, health and hygiene, and technical/institutional sustainability. Applying this to Montero, Bolivia, the study compares four systems: conventional gravity-fed sewers (System 1), condominial sewers (System 2), septic tanks with soak pits (System 3), and urine-diverting dry toilets (UDDTs) (System 4). Findings indicate that while conventional systems have high social acceptability, they are the least affordable and most vulnerable to water scarcity and flooding. System 4 (UDDTs) performs best in health, water use, and climate resilience. Optimization—such as adding inlet screens, using personal protection equipment (PPE), and implementing scheduled emptying—generally improves health and environmental outcomes but increases technical complexity and reduces economic sustainability. The report argues for a city-wide inclusive sanitation approach using a mix of these systems to balance trade-offs between cost, health, and environmental protection.

The road freight sector is undergoing a transformation driven by automation, digitalization, and electrification. While these trends promise significant reductions in greenhouse gas emissions and operational costs, they shift environmental hotspots from vehicle operation to the manufacturing phase, particularly regarding battery mineral extraction. Social challenges include potential job insecurity for drivers and the risk of exploitation within digital 'gig economy' platforms.

The report establishes a baseline emissions inventory for the Genesee-Finger Lakes Region, identifying transportation, agriculture, and residential heating as primary emission sources. It details a methodology aligned with New York State and IPCC guidelines, providing county-level breakdowns and a baseline projection that suggests a slight increase in total emissions by 2050.
