California plans to respond to a likely rollback in federal vehicle emission rules by banning the sale of cars that don’t meet the state’s tougher pollution regulations, sources tell Bloomberg News.

Currently, California law dictates that vehicles certified at the federal level automatically comply with the state’s standards. But the two sets of regulations are likely to diverge significantly in 2022-2025. The Environmental Protection Agency is widely expected to announce this weekend that it will ease currently scheduled federal regulations for that period.

The California Air Resources Board has declared repeatedly that it intends to enforce the current standards for 2022-2025. Those regulations would reduce carbon dioxide emission limits enough to push on-road average fuel economy requirements to about 36 mpg. CARB also is readying even tougher standards to take effect by 2030.

The District of Columbia and 13 other predominantly eastern states also embrace CARB’s standards. The group represents about 30% of the U.S. passenger vehicle market.
