California is telling automakers that they must comply with its strict rules on greenhouse gases even if the Trump Administration relaxes regulations nationally.
The California Air Resources Board approved a regulation that will cut carbon releases by new cars starting in 2021. If automakers want to sell cars in the nation's largest state, they will have to comply.
The Environmental Protection Agency announced in August that it plans to lower standards on tailpipe emissions and would force California to accept them. The state answered back, saying it was willing to go to court to defend its higher standards.
Car makers have asked California to wait until it negotiates a compromise with the Trump Administration, saying it does not want different rules in each state.
