As part of Gov. Gavin Newsom's administration's attempt to combat climate change, California has banned the purchase of gasoline-fueled vehicles by government groups, according to the Sacramento Bee.

The state fleet includes about 51,000 cars and trucks, according to the governor's office. As of last year, more than 3,000 of those vehicles were hybrids or zero-emission vehicles, according to the Department of General Services.

The rule also mandates that beginning next year, state agencies purchase vehicles from manufacturers that recognize the state's authority to set its own emission standards. Currently, the Trump administration is trying to revoke that ability.

With backing from Honda, Ford, BMW, and Volkswagen, California is challenging the administration in court. The automakers have agreed to comply with California's standards, regardless of federal standards.

General Motors, Toyota, Mazda, and Fiat Chrysler are backing the Trump administration.
