MONTPELIER, Vt. (AP) — Vermont Attorney General T.J. Donovan says the state is one of 23 states suing to stop the Trump administration from revoking California's authority to set emission standards for cars and trucks.
Donovan says Vermont signed on to the lawsuit filed Friday by California Attorney General Xavier Becerra.
On Thursday the Trump administration revoked California's authority to set its own auto emission standards. The state has had that power for decades under a waiver from the Clean Air Act.
The lawsuit argues that the National Highway Traffic Safety Administration does not have the authority to revoke California's waiver. Vermont has adopted the California standards.
Four automakers have said they would voluntarily follow California's standards.
In addition to the states, the lawsuit includes the District of Columbia, Los Angeles and New York.
