The Green Climate Fund Authorization Act of 2025 aims to provide financial support to help combat climate change, particularly focusing on vulnerable communities both in the United States and around the world. The main objective is to authorize funding for the Green Climate Fund, which assists developing countries in reducing greenhouse gas emissions and adapting to climate impacts. Key provisions of the Act include the authorization of $4 billion for each of the fiscal years 2026 and 2027 to be contributed to the Green Climate Fund.
