The Trump administration on Thursday proposed to roll back federal fuel efficiency requirement for passenger vehicles at the 2020 model year level of 35 mpg (14.8 kpl) instead of letting them continue to rise through 2025 to nearly 50 mpg (21.2 kpl) as planned by the Obama administration.

The proposal also suggested revoking the 1975 law that provides California with a waiver from federal rules allowing it to implement stringent standards compared to rest of the country.

The draft rule which was jointly written by the United States Environment Protection Agency (EPA) and the National Highway Traffic Safety Administration (NHTSA) includes a range of options for modifying the fleet fuel economy end emission standards. However, it also makes it clear that the preferences are to freeze the standards at the 2020 model year.

Several environmentalists and lawmakers from all over the country criticised the move. Jerry Brown said his state “will fight this stupidity in every conceivable way possible.”

Under the current rules, standards vary by the model based on a size footprint. The proposal to revoke, however, was widely accepted as the implementation would help harmonize the execution of national programmes. The lack of such a unified law, automakers of the country face the expense of building and marketing vehicles for two different markets which may result in losing sales of some models in certain states.
