Disqualifies state standards that limit sale or use of internal combustion engine vehicles from receiving Clean Air Act waivers and requires EPA review/revocation of certain recent waivers.
Official title: Amend the Clean Air Act to prevent the elimination of the sale of motor vehicles with internal combustion engines, and for other purposes.
Introduced March 12, 2025 by Markwayne Mullin · Last progress March 12, 2025
Prohibits the EPA from granting or recognizing Clean Air Act waivers for any state standard that directly or indirectly limits the sale or use of new motor vehicles with internal combustion engines, and forbids treating post‑enactment changes as covered by prior waivers. It also requires the EPA Administrator to review and revoke any waivers issued between January 1, 2022 and the law's enactment if those waivers allow or cover standards that limit sale or use of internal combustion engine vehicles. The change narrows the kinds of state vehicle-emissions or vehicle‑sales rules that can receive federal waiver approval and directs retroactive revocation of certain recent waivers.
