The document reports that as of March 31, 2025, the Inter-American Institute for Global Change Research had received 78% of the approved contributions for the 2024-2025 fiscal year. While overall expenses were 10% lower than budgeted, the Executive Directorate warns that delays in voluntary contributions significantly limit its operational capacity. The report also outlines projected voluntary contributions for the next three fiscal years, with the USA providing the largest share.

The IAI is requesting an operating budget of US$ 1.68 million for the 2025-2026 fiscal year, which remains unchanged from the previous year. Preliminary requests for subsequent years show a gradual increase, reaching US$ 1.8522 million by 2027-2028. The budget is funded by contributions from member countries, with the USA providing the largest share. The IAI reports administrative adjustments to optimize spending and a reduction in IT costs following its move to Panama.

This research paper outlines the priorities of South Africa's 2025 G20 presidency regarding climate finance, emphasizing the mobilization of resources for just energy transitions and the elevation of African concerns within the G20 framework, building upon the foundations laid during Brazil's 2024 presidency.

The report finds that human-caused climate change significantly increased extreme heat and health risks globally from December 2024 to February 2025. At least 1.8 billion people experienced temperatures at least twice as likely due to climate change every day of the period, with exposure peaking at 3 billion people on February 28, 2025. Africa was particularly affected, with 293 million people experiencing 30 or more 'risky heat days' added by climate change. The analysis also highlights that 110 out of 220 analyzed countries and 287 out of 940 cities saw the average person experience strong climate influence for at least one-third of the season.

The programme aims to protect approximately 1.52 million direct beneficiaries and 4.15 million indirect beneficiaries in the Amazon Basin from climate-induced water insecurity. It focuses on three components: strengthening hydro-meteorological knowledge and early warning systems, catalyzing investments in climate-resilient water, sanitation, and waste (WSW) infrastructure, and enhancing regional governance and transboundary cooperation. The initiative employs a mix of Ecosystem-based Adaptation (EbA), nature-based solutions (NbS), and advanced monitoring technologies to mitigate the impacts of extreme droughts and floods.

The International Institute for Sustainable Development calls for the inclusion of natural resource taxation in the FfD4 outcome document, noting that the current zero draft overlooks this critical revenue source. The author highlights that resource rents are vital for many lower- and middle-income countries but are often undermined by tax avoidance and weak governance. The statement proposes specific amendments to the FfD4 draft to ensure fair fiscal terms and better benefit-sharing, particularly regarding critical energy transition minerals.

The document outlines a comprehensive approach to reducing methane emissions from solid waste, which accounts for approximately 20% of global anthropogenic methane emissions. It proposes a policy matrix categorized into legislative/regulatory, market-based, voluntary, and information/education approaches, mapped across the integrated solid waste management (ISWM) chain. The guide emphasizes that limiting global warming to 1.5 degrees Celsius requires the global implementation of solutions across all three categories of the ISWM chain: waste prevention/minimization, source separation/treatment of organics, and improved landfill engineering. It provides detailed case studies from Colombia, Germany, India, Italy, Peru, the Republic of Korea, and the United States to illustrate how different policy combinations are applied based on national contexts.

The waste sector accounts for approximately 20% of global anthropogenic methane emissions, equivalent to 5.4 Gt CO2e annually. This guide proposes a policy matrix organized by the solid waste management (SWM) chain to help policymakers implement a combination of legislative, market-based, voluntary, and educational tools. Key strategies include waste prevention, organic waste diversion (composting and anaerobic digestion), and improved landfill engineering (gas capture and biocovers). The document emphasizes that meeting the 1.5 degrees Celsius warming limit requires a comprehensive approach across the entire SWM chain rather than isolated solutions. It provides case studies from Colombia, Germany, India, Italy, Perú, the Republic of Korea, and the United States to illustrate how different nations layer these policy tools to reduce emissions.

The document analyzes climate obstruction in Argentina and Brazil, identifying a shift toward explicit climate denial under President Javier Milei in Argentina and a complex mix of agribusiness-led obstruction and state-driven fossil fuel expansion in Brazil. It highlights how developmentalist ideologies and economic lobbying in both nations hinder the transition to low-carbon economies, despite Brazil's recent efforts to reduce Amazonian deforestation.

The document outlines how a proposed Fossil Fuel Non-Proliferation Treaty would fill a regulatory void by focusing on the supply side of fossil fuels, which is not explicitly addressed in the Paris Agreement or UNFCCC. It proposes a 'coalition of the willing' approach to set high ambition standards, using majority decision-making to avoid the consensus-based deadlocks of the UNFCCC. The treaty aims to end new fossil fuel expansion, phase out existing projects in line with a 1.5°C limit, and provide financial and technical support for a just transition for dependent communities and workers.

The document proposes a new binding legal instrument, the Fossil Fuel Non-Proliferation Treaty, to accelerate the phase-out of coal, oil, and gas. It argues that while the Paris Agreement and UNFCCC provide a general framework for climate action, they lack specific mechanisms to regulate the supply side of fossil fuels. The proposed treaty would focus on three pillars: ending new fossil fuel projects, phasing out existing infrastructure aligned with a 1.5 °C limit, and ensuring a just transition for dependent communities. Unlike the consensus-based decision-making of the UNFCCC, the treaty would employ a 'Coalition of the Willing' approach and majority voting to prevent a small number of states from blocking ambitious action.

The 2030 Global Forest Vision provides a framework for governments to accelerate progress toward 2030 forest goals through actions in national planning, trade, finance, land rights, and governance. It emphasizes the need for integrated climate and biodiversity plans, the scaling of finance via mechanisms like the Tropical Forest Finance Facility (TFFF) and REDD+, and the recognition of Indigenous and local community land rights. The report also calls for financial regulators to address forest-related risks, the repurposing of harmful agricultural subsidies, and the restructuring of sovereign debt to value natural capital.

The report identifies systemic failures in the global financial architecture that drive deforestation and proposes five priority actions: reforming multilateral public finance, overhauling sovereign debt, scaling high-impact funding mechanisms like the Tropical Forest Forever Facility, repurposing harmful agricultural subsidies, and embedding nature-related risks into financial regulatory frameworks.

The document examines the failures of traditional investment treaties and the ISDS system, which it argues prioritize investor protection over public interest and sustainable development. It highlights the high financial costs of ISDS awards, the phenomenon of 'regulatory chill' where states avoid necessary environmental or social reforms to avoid litigation, and the lack of investor obligations. The report advocates for a shift toward treaties focused on investment facilitation and cooperation, the termination of outdated agreements, and a coordinated global effort to modernize investment governance.

The document examines the role of foreign direct investment (FDI) and the legal frameworks governing it, specifically criticizing the ISDS system for prioritizing investor protections over public interest and sustainable development. It details the financial and regulatory burdens placed on states by ISDS awards and advocates for a proactive, holistic reform of investment governance.

The document examines the role of legal frameworks in governing foreign direct investment (FDI) and critiques traditional investment treaties and the ISDS system. It argues that these frameworks often prioritize investor protections over public interests, creating a 'regulatory chill' and imposing high financial burdens on states, particularly in the context of the energy transition. The guide proposes a shift toward treaties focused on cooperation and sustainable development, while detailing various national, bilateral, and multilateral reform strategies.

The document is a global communiqué from March 2025 detailing a consensus among 28 countries to prioritize justice and inclusivity in the energy transition. It emphasizes the insufficiency of current investment levels in developing countries and calls for the use of concessional financing, technology transfer, and country-specific transition plans to eradicate energy poverty and build climate resilience. The signatories commit to fostering domestic manufacturing, diversifying supply chains, and strengthening regional cooperation projects such as Mission 300 and the RELAC Initiative to align national investment with Paris Agreement goals.

The report assesses the circular economy (CE) strategies of Bogotá and Buenos Aires, identifying a common over-reliance on waste management and a lack of holistic, long-term visions. It emphasizes the critical role of the informal waste sector, which supports millions of livelihoods in the region, and advocates for their formal integration into urban governance. Key recommendations include adopting the 10-R framework to move beyond recycling toward refusing and rethinking consumption, improving waste infrastructure, and implementing extended producer responsibility (EPR) schemes.

The document highlights a critical gap between the estimated loss and damage (L&D) finance needs of developing countries (USD 400 billion to 1.6 trillion per year by 2030) and current pledges to the Fund for responding to Loss and Damage (USD 745 million as of December 2024). It proposes a variety of innovative instruments to generate revenue, categorized by their funding potential and alignment with the 'polluters pay' and historical responsibility principles. High-potential instruments include wealth taxes (up to USD 2 trillion per year) and windfall taxes (up to USD 1 trillion per year). The brief recommends that high-income countries implement these instruments nationally or advocate for global frameworks through forums like the G20, IMF, and the UN Framework Convention on International Tax Cooperation to ensure equitable climate finance.

Brazil has announced a new NDC targeting a greenhouse gas emissions reduction of 59–67% by 2035 relative to 2005 levels. To achieve this, the government is developing a 2024-2035 Climate Plan consisting of an Adaptation Plan and a Mitigation Plan. The document argues that private sector investment is essential for success and recommends harmonizing sectoral policies, promoting corporate transition plans, and strengthening public-private dialogue. Key focus areas include halting illegal deforestation, decarbonizing agriculture, transitioning energy and industry away from fossil fuels, and implementing a national Emissions Trading System (ETS).
