Republican US Senators propose repeal of California emission rules

Four Republican U.S. Senators proposed Thursday repealing landmark California vehicle emissions regulations in an effort to prevent the State from imposing more stringent?tailpipe requirements that the federal government.

The U.S. Environmental Protection Agency ?in ?June sent the Republican-controlled Congress state vehicle emissions rules for potential repeal, saying the waivers granted under the Clean Air Act for California environmental regulations approved under prior Democratic administrations should have been sent to lawmakers under the Congressional Review Act. California filed a federal lawsuit to stop the action, claiming it was 'illegal' to send the waivers under the Congressional Review Act to the Senate.

The CRA allows for repeal by a simple majority rather than 60 votes required in most cases.

Cynthia Lummis and Eric Schmitt of the California Air Resources Board, along with Pete?Ricketts, Jon Husted, said that the waivers allow the California Air Resources Board to "impose its regulatory agenda well beyond California's boundaries."

The Trump administration has mounted a multifaceted effort to prevent California from requiring cleaner vehicles and more electric vehicles. The EPA 'has also enacted regulations making it easier for automakers sell more gasoline powered cars and trucks while making it expensive to purchase EVs.

California was granted authority to set its own emission standards, including for lawn and garden equipment and power washing machines. These rules have prompted companies to develop cleaner electric models in order to reduce emissions. California received approval from the EPA in 2022, under the then-President Joe Biden. The state's vehicle rules called Advanced Clean Cars I (ACC?I) remain in place and are targeted for waiver.

California's rules force automakers to sell an increasing number of electric cars and adhere to stricter limits on tailpipe emission than federal regulations. California says that the federal fuel economy rules will be rolled back by Donald Trump's administration, but he plans to do so under Republican President Donald Trump.

After Toyota, General Motors, and other automakers requested relief from California's emission regulations, Congress last year revoked the authority of?California for it to ban traditional gasoline-powered cars after?2035.

Congress passed a law in 2025 that will stop automakers from being penalized for failing to meet vehicle tailpipe standards. This legislation will save them hundreds of millions of dollar. (Reporting and editing by Nick Zieminski, Matthew Lewis, and David Shepardson)
