US sues California over zero-emission vehicle rules
The Trump administration filed a lawsuit against the state of California on Thursday, challenging the legality of the state’s zero-emission vehicle (ZEV) mandates and tailpipe greenhouse gas emissions rules.
The U.S. Transportation Department sued the California Air Resources Board (CARB) in U.S. District Court, arguing that the state’s vehicle regulations are preempted by federal law and conflict with nationwide standards, News.Az reports, citing Reuters.
The dispute follows President Trump’s 2023 legislation that rescinded California’s Advanced Clean Cars II waiver, which aimed to phase out gasoline-powered cars by 2035. Despite the federal move, California’s prior rules remain in effect, prompting the lawsuit.
