Sustainable International Financial Institutions Act of 2025

This bill requires U.S. representatives at 12 major international financial institutions (including the World Bank and regional development banks) to vote against new fossil fuel projects and support clean energy transitions. It mandates that the U.S. reduce its financial contributions to any institution funding new fossil fuel capacity (e.g., oil, gas, coal projects), depositing the withheld funds into an escrow account until the institution stops such funding. The bill defines fossil fuel broadly to include unconventional sources like oil sands and shale gas, and prohibits U.S. foreign assistance for fossil fuel activities or related infrastructure. These changes directly affect how the U.S. engages with international financial institutions and their funding decisions.
