Elected on a platform to do away with regulatory interference, especially Obama-era fuel economy targets, the Trump Administration is now looking to end California’s waiver under the Clean Air Act.

Ending the waiver effectively means that the United States would finally have a unified set of regulations for vehicles emissions and fuel efficiency standards, as California (through the California Air Resources Board) often sets higher requirements, through its Clean Air Act waiver.

Looking to gut the regulatory force of CARB, this news would also mean that vehicle makers would have lower targets to hit for gas mileage efficiency (37mpg instead of 46.8mpg), which in turn means that brands would have to sell fewer electric vehicles as well.

Lastly, under the proposed changes, vehicle emission standards would freeze at the planned 2020 levels, until the year 2026.
