California plans to ban the sale of new gasoline-powered passenger cars and trucks starting in 2035 as the top U.S. auto market shifts to electric vehicles to reduce climate-warming emissions, Gov. Gavin Newsom said Wednesday.

The move is the most significant yet by a U.S. state aimed at ending the use of fossil fuel-burning internal combustion engines, and clashes with the pro-fossil fuel policies of President Donald Trump's White House.

Newsom declared earlier this month he would step up the state's already aggressive efforts to combat climate change amid a record wildfire season.
