The Polluters Pay Climate Fund Act of 2025 taxes fossil fuel companies based on their greenhouse gas emissions from the years 2000-2023, allocating \$1 trillion to a "Polluters Pay Climate Fund." This fund will support climate resilience, disaster response, and environmental justice initiatives, with a significant portion dedicated to FEMA and grants under the Clean Air Act, and requires that 40% of the fund must benefit environmental justice communities. The Act clarifies that it does not relieve polluters of existing liabilities or preempt state and local climate-related laws.
