Stop CARB Act of 2024

This bill repeals key provisions of the Clean Air Act that allow California to set its own vehicle emission standards and grants other states the ability to adopt those standards. It directly affects California's authority to enforce its stricter emissions rules for vehicles and prevents other states from using California's standards as a federal baseline. The bill eliminates all existing federal waivers for California's standards and blocks future applications for such waivers, effectively ending the federal approval process for California's vehicle regulations. This would remove the legal basis for California's unique vehicle emission standards to apply nationwide.
