California Emissions Waivers Face GOP Repeal Push

GOP Senators Push to Repeal California Emissions Waivers

Four GOP senators are urging Congress to repeal California emissions waivers that permit the state to establish stricter tailpipe emissions requirements. The senators argue that the waivers have enabled the California Air Resources Board to impose its regulatory agenda far beyond California’s borders. In June, the U.S. EPA sent state vehicle emissions rules to Congress for potential repeal, contending that waivers issued under the Clean Air Act for California environmental regulations approved under Democratic administrations should have been submitted to Congress under the Congressional Review Act. CRA consideration permits repeal through a simple majority vote, rather than the 60 votes generally required for most legislation.

Trump Administration Targets California Vehicle Rules

The Trump administration has pursued several measures aimed at limiting California’s ability to require cleaner vehicles and higher EV adoption. The EPA has also implemented rules intended to make it easier for OEMs to sell more gasoline-powered cars and trucks while increasing the cost of purchasing EVs. In 2025, Congress rescinded California’s authority to prohibit traditional ICE vehicles by 2035 after Toyota Motor Corp and General Motors, among other OEMs, lobbied for relief from the state’s emissions requirements. Congress also enacted legislation in 2025 that halted the collection of penalties associated with failure to meet vehicle tailpipe standards.
