California’s Governor signed a September 2020 executive order requiring sales of all new passenger vehicles to be zero-emission by 2035 and additional measures to eliminate harmful emissions from the transportation sector. Following the order, the California Air Resources Board will develop regulations to mandate that 100 percent of in-state sales of new passenger cars and trucks are zero-emission by 2035 – a target which would achieve more than a 35 percent reduction in greenhouse gas emissions and an 80 percent improvement in oxides of nitrogen emissions from cars statewide. In addition, the Air Resources Board will develop regulations to mandate that all operations of medium- and heavy-duty vehicles shall be 100 percent zero emission by 2045 where feasible, with the mandate going into effect by 2035 for drayage trucks. To ensure needed infrastructure to support zero-emission vehicles, the order requires state agencies, in partnership with the private sector, to accelerate deployment of affordable fueling and charging options. It also requires support of new and used zero-emission vehicle markets to provide broad accessibility to zero-emission vehicles for all Californians. The executive order will not prevent Californians from owning gasoline-powered cars or selling them on the used car market.
