US HB5952

U.S. Executive Directors at 12 international financial institutions (including World Bank, IMF, regional development banks) must vote to oppose any investment, loan, or assistance that creates new fossil fuel capacity or extends existing fossil fuel infrastructure

Secretary of Treasury must annually calculate each institution's fossil fuel-related expenditures and reduce U.S. contributions by that amount, depositing withheld funds into an escrow account until the institution stops funding fossil fuel projects

Prohibits all U.S. government agencies—including DFC, Export-Import Bank, USAID, Trade and Development Agency, and Millennium Challenge Corporation—from providing any loans, insurance, guarantees, or technical assistance for fossil fuel activities

Requires phasing out international financial institution funding for internal combustion engines in passenger vehicles and buses by 2031

"Fossil fuel activity" is broadly defined to include exploration, production, refining, transportation (including pipelines), distribution, and combustion of coal, petroleum, natural gas, and derivatives including oil sands, oil shale, and methane hydrates
