France has integrated climate considerations into its annual budgetary process through a 'Green Budget' published in 2021, which rates all State expenditures on their environmental impact. This system uses a five-category scale and six environmental goals to ensure government agencies consider net-zero progress in their spending. A notable application was the 2021 COVID-19 recovery plan, which mandated that 30% of its funds be allocated to favorably rated green investments.

Denmark's power sector shifted from 3% renewable generation in 1990 to over 80% by 2020, driven by a 24-fold increase in wind capacity and a 76% reduction in carbon dioxide emissions. This transformation resulted from sustained R&D investment, feed-in tariffs, streamlined institutional planning via the Danish Energy Agency, strong international grid interconnection, and community ownership models. The government has set ambitious 2030 targets, including 100% renewable electricity generation, supported by a social safety net and dialogues with unions to ensure a fair transition for fossil fuel workers.

Costa Rica's 2019 National Decarbonization Plan established a midcentury net-zero target covering all greenhouse gases and sectors, except international shipping and aviation. The plan utilized a backcasting approach divided into three phases: foundations (2018–22), inflection (2023–30), and massive deployment (2031–50). This robust framework attracted nearly $1 billion in funding from the International Monetary Fund and Inter-American Development Bank, which incentivized the administration of President Rodrigo Chaves to maintain climate objectives despite a campaign focused on changing course from the previous government. Current priorities include the operationalization of 1,000 electric buses and agricultural emissions reduction, with a strategic shift toward attracting large-scale finance for specific sectors.

The document describes how South Africa's Presidential Climate Commission (PCC), situated within the Presidency, facilitates a just transition through a multi-stakeholder approach involving government, business, labor, civil society, and traditional leadership. It highlights the development of the Just Transition Framework, adopted by the Cabinet in August 2022, which was created through extensive evidence gathering, public workshops, community consultations, and expert essays to ensure the process was inclusive and tailored to those most impacted by the shift from fossil fuel-based economies.

The project tested communication strategies to encourage diet change among a specific demographic in Moston, Manchester. Findings indicate that health benefits, cost savings, and community-led messaging are more effective than climate-focused arguments. The study emphasizes avoiding 'marketing' terms like 'plant-based' and instead focusing on simple swaps and authentic, peer-to-peer sharing within the community.

The report examines the gendered impacts of climate change and environmental degradation in South Africa, focusing on air pollution, water access, agroecology, and energy poverty. Through case studies, it highlights how women-led initiatives—such as legal challenges against air pollution in the Highveld, agroecology gardens in Burundi, solar energy projects in Johannesburg, and waste management in Durban—address systemic inequalities and build community resilience. It argues that a Just Transition must integrate an intersectional gender perspective to be effective.

The report examines how the City of Nelson, Halifax Regional Municipality, and EPCOR integrate natural infrastructure into their water management. It highlights the use of local bylaws in Nelson, a multi-level policy hierarchy in Halifax, and a hybrid grey-natural approach by EPCOR in Edmonton to enhance climate resilience and flood mitigation.

The report examines how governments can monitor green public procurement (GPP) to track progress toward climate goals. It categorizes monitoring into institutionalization, outputs, and outcomes, while detailing specific tools for measuring CO2 impacts. Through case studies of South Korea, Japan, Slovenia, Denmark, Malaysia, and the Netherlands, it identifies key success factors such as strong legal mandates and e-procurement integration. It also highlights significant barriers, including data insufficiency, decentralized procurement structures, and a lack of specialized technical skills. The document concludes with recommendations for governments to define clear targets, mandate monitoring through policy, and strengthen data management systems.

The document outlines strategies for reducing methane emissions from US municipal solid waste (MSW) landfills, emphasizing the transition from traditional manual surface emissions monitoring (SEM) to advanced technologies like satellites, aircraft, drones, and fixed sensors. It provides a six-step framework for monitoring-informed mitigation: selecting a system, deploying it, pinpointing sources, identifying root causes, deploying mitigation measures, and verifying reductions. The guide highlights that while organic waste diversion is critical for future emissions, improving waste-in-place controls offers immediate climate benefits.

The Sierra Leone Healthcare Electrification Project, managed by Sustainable Energy for All (SEforALL) and funded by the UK, is replacing diesel generator reliance with solar PV and battery storage in health facilities. Following a Market Assessment and Roadmap, the project initially equipped six hospitals in Freetown, Kambia, Masanga, Kabala, and Bonthe with over 0.6 MWp of solar capacity, reducing diesel usage by 58% to 99%. The project has since expanded to include an additional hospital and 25 community health centres, while providing technical training to young women in the renewable energy sector.

The Stockholm Environment Institute's 'Clean and Green' (L&V) framework moves beyond eliminating open defecation to integrate health risk management with the safe reuse of productive waste. The framework consists of a 'Clean path' to reduce pathogen exposure and a 'Green path' to recover nutrients (N, P, K) and organic matter from human and animal waste. Following pilot tests in Burkina Faso, the document argues for the framework's application in Bolivia, where rural poverty is high and agricultural productivity could be enhanced by recycling nutrients from human excreta, which is estimated to provide the equivalent of 40 kg of chemical fertilizer per household annually.

Aptech implemented two water projects in Somaliland. In Hargeisa, a hybrid PV and generator system at three Laasdhure boreholes provides an additional 4 million liters of drinking water daily. In Dilla, a system of shallow wells with 0.37kw pumps and hybrid power provides 50m3 of water daily for community and livestock use.

The paper examines how a network of 11 community radio stations from the Colombian Amazon participated in the Belém Summit (August 8-9, 2023) to provide a grassroots perspective on the protection of the Amazon biome. It argues that community media offer a more truthful and critical treatment of information than mass media because reporters live the territorial realities, such as lack of basic services and state neglect. The author highlights that these community-led reports reached over 5 million people across Latin America and the Caribbean. The document further critiques the resulting 'Belém Declaration,' arguing that it lacks a strong position against fossil fuel extraction and fails to fully integrate the ancestral vision of indigenous peoples or the critical discourse of popular sectors.

The report provides an evidence-based narrative of the April 2022 floods in Durban, which saw 304-311 mm of rain in 24 hours, resulting in 450 deaths and 40,000 displaced people. It evaluates the city's resilience strategies, such as the Community Based Early Flood Warning System (CBFEWS) and the Transformative Riverine Management Programme (TRMP), while detailing the devastating cumulative impacts on vulnerable populations. Through five case studies—including the Quarry Road West informal settlement and the Dassenhoek peri-urban area—the document highlights profound material loss, psychological trauma, and the erosion of development gains, arguing that such events serve as proxies for the broader impacts of climate change.

The report analyzes deforestation policies in five producing countries—Costa Rica, Gabon, Indonesia, Peru, and Rwanda—to identify successful strategies for forest conservation. It highlights seven key success factors for governments in the Global South, including the use of tailored measure combinations, targeting high-risk areas, and leveraging both public and private funding. Additionally, it examines how voluntary sustainability standards (VSSs) can complement legal regulations to help private sector actors reach net-zero emissions, though it notes that limited alignment and low corporate uptake currently hinder their impact.

A case study on the installation of Sustain Solar SUSTAIN BOXES™ in two Malawian health clinics by International Power Control Systems (IPCS), providing off-grid renewable power for critical medical equipment and testing a sustainable business model.

The report analyzes the US Department of Energy's Energy Infrastructure Reinvestment (EIR) program, which provides low-cost loans to repurpose energy infrastructure. It demonstrates that using EIR to refinance remaining coal plant balances and fund new clean energy assets can significantly reduce costs for ratepayers. Case studies of Alliant in Iowa and Ameren in Missouri show potential net present value (NPV) savings of $124 million and $413 million, respectively, compared to traditional utility financing. The report emphasizes the urgency for utilities to apply before the September 2026 approval deadline.

Ember's submission to the NSW Parliament inquiry into Net Zero highlights that the coal mining sector is the biggest potential risk to the state's emission goals. The document argues that existing federal mechanisms, such as the Safeguard Mechanism and the Coal Mine Waste Gas method, are insufficient to drive material onsite reductions. Using Tahmoor Colliery as a case study, Ember demonstrates that Ventilation Air Methane (VAM) mitigation via Regenerative Thermal Oxidiser (RTO) technology is technically and commercially feasible but underutilised due to a lack of state-led regulatory pressure and the availability of carbon offsets. The submission calls for a pause on new coal mine expansions and a dedicated report from the Net Zero Commission by June 2025 to assess sectoral risks and develop a coal-specific emissions target.

WRI Indonesia's Cities4Forests initiative helped Jakarta implement two new regulations in 2021 regarding tree management and park provision. This collaboration led to the creation of 54 new urban parks since 2022 and the planting of over 65,000 urban trees, specifically targeting underserved areas to mitigate air pollution, extreme heat, and flooding.

The São Paulo Complete Streets Network, a partnership between WRI and the Bloomberg Initiative for Global Road Safety, supported Brazilian cities in redesigning infrastructure to protect pedestrians, cyclists, and public transit users. Between 2020 and 2023, ten cities in São Paulo implemented measures such as expanded sidewalks, cycle lanes, and reduced speed limits. These efforts contributed to a shift where the crash mortality rate in these cities fell below the state average of São Paulo in 2022, compared to 2021 when it was higher.
