California governor Gavin Newsom issued an executive order requiring all cars and light trucks to be zero-emissions vehicles by 2035. The order is intended to combat climate change by banning the sale of gas-powered vehicles in favor of battery-electric and fuel cell vehicles.

The order does not outright ban gas-powered vehicles in the state in 2035. The sell of used vehicles and gas-powered vehicles in-service in 2035 will be exempt from the order, but all new cars and light trucks must be designated a zero-emission vehicle.

California Air Resources Board (CARB) and other state agencies will adopt policies necessary to enforce the order.

This latest move advances a previously-announced order requiring all automakers who sell medium and heavy-duty vehicles to start migrating to zero-emission vehicles in 2024, with the transition complete by 2045.

The ban on gas-powered vehicles may not stop at California. There’s 11 other states and Washington DC who follow CARB emission guidelines. If they choose, they too could follow California’s lead in banning gas-powered light vehicles by 2035. At this point the other states have not confirmed wether or not they will adhere to the ban.

California’s planned ban of gas-powered vehicles isn’t exactly novel. Many European cities have announced similar bans with varying degrees of aggressiveness.
