US sues California over zero emission vehicle, greenhouse gas rules

The Trump administration sued California on Thursday, claiming that the state's rules for zero-emission vehicles and tailpipe greenhouse gas emissions are illegal. Federal law preempts them.

The U.S. Transportation Department filed a lawsuit against the California Air Resources Board at U.S. District Court, California to challenge vehicle regulations that are still in place after President Donald Trump's legislation signed last year that overturned California's Advanced Clean Cars II rule that aims to phase out new gasoline-powered vehicles by 2035.

The lawsuit is seeking a court ruling that declares all California zero-emissions vehicle mandates to be illegal and unenforceable.

Jonathan Morrison, the head of the National Highway Traffic Safety Administration said that this litigation would help automakers to design and manufacture cars and trucks in order to meet a federal fuel efficiency regulation.

California received a?approval from the Environmental Protection Agency in 2022 for its current vehicle rules, known as Advanced Clean Cars I. The state claims that these are still in force. California Air Resources Board didn't immediately respond to a request for comment.

The Trump administration has been trying to stop California from establishing vehicle regulations for years. It sued California in August to prevent the state from enforcing strict emissions standards for heavy duty trucks.

California's regulations require automakers sell an increasing number of electric cars and adhere to increasingly strict limits on tailpipe emission.

These rules are stricter than the ones imposed by the Trump administration which plans to rollback federal fuel economy regulations.

California claims that the cost of EVs is higher than the savings in fuel for consumers.

After Toyota and the Detroit Three successfully lobbied Congress, the White House and Congress to get relief from California's emission regulations, Congress has revoked the authority of?California.

The White House also "significantly" weakened federal rules on tailpipes, and Congress passed legislation that would stop the collection of penalties for vehicles not meeting tailpipe standards.
