Imposes a new federal tax on the current stock of greenhouse gas emissions and directs the revenue into a new "Polluters Pay Climate Change Fund" to pay for climate resilience, adaptation, disaster response, and environmental-justice–focused grants. The measure bars deductions for the new tax, requires minimum allocations to FEMA and EPA grant programs, mandates that at least 40% of annual spending benefit environmental justice communities, and preserves state and local authority and existing legal claims against fossil fuel actors.
