Green Climate Fund Authorization Act of 2025

This bill, titled the Green Climate Fund Authorization Act of 2025, authorizes significant appropriations for international climate financing. Specifically, it authorizes $4,000,000,000 for each of fiscal years 2026 and 2027 for contributions to the Green Climate Fund . Congress finds that while this funding is crucial, the overall climate financing needs to limit global warming to 1.5 degrees Celsius are substantially greater. The legislation establishes a clear policy for United States climate financing, emphasizing principles of environmental justice and climate justice . This policy mandates support for programs developed by recipient countries, requires free, prior, and informed consent from indigenous and impacted communities, and promotes gender equality. It also ensures that projects include best practices for environmental and social safeguards, addressing both mitigation and adaptation efforts. The bill underscores the importance of the Green Climate Fund as a vital institution for helping developing countries reduce greenhouse gas emissions and adapt to climate change impacts, noting past U.S. under-contributions to the fund.
