Sept. 6, 2019—Two U.S. agencies are preparing to submit for final White House regulatory review a plan to revoke California's authority to set its own vehicle greenhouse gas standards, according to Reuters.
The plan would also declare that states are pre-empted from setting their own vehicle rules. It would not revoke California's ability to set low-emission car standards that has been in place since 1990.
The EPA and the National Highway Traffic Safety Administration (NHTSA) are expected to seek approval to finalize the first portion of the rule dealing with California and other states before completing action on setting yearly fuel efficiency requirements.
California accounts for about 12 percent of American vehicle sales.
