California set to move forward with plan to ban sale of all gas cars by 2035

California could be moving one step closer to banning the sale of gas vehicles by 2035, with the state's Air Resources Board (CARB) expected to vote in favor of such a plan Thursday.

Daniel Sperling, a member of the board, told CNN that he was "99.9% confident the measure would pass" on Thursday.

"This is monumental," Sperling said. "It's important not just for California, but it's important for the country and the world."
