EPA proposes rescission of 2009 Endangerment Finding and vehicle GHG standards

Summary

In August 2025, EPA put on paper a plan to unwind the core of federal climate regulation for vehicles. The proposal would rescind the 2009 Endangerment Finding — the scientific-legal judgment that greenhouse gases endanger public health — and repeal greenhouse-gas standards for cars and trucks. Signed July 29, published August 1. A proposal is not a final rule; it is the public start of taking the finding off the books. The final came in February 2026.
