The Clean Air Act generally bars states from setting their own emission standards for new motor vehicles unless the Environmental Protection Agency (EPA) grants a waiver.² This bill would make state standards that directly or indirectly limit the sale or use of new vehicles with internal combustion engines, such as gasoline or diesel engines, ineligible for those waivers.^2,3 It would require the EPA to revoke any waiver granted from January 1, 2022, until the bill's enactment if the state standards limit such vehicles, and would bar the EPA from treating state standards amended after enactment as covered by an existing waiver.²
