Washington and Massachusetts are following a policy from California to ban the sale of new gasoline-powered cars by 2035.

Rules from the California Air Resources Board (CARB) require 35% of new vehicles to produce zero emissions by 2026 before rising to a 68% benchmark by 2030 and a 100% level by 2035. Both Washington and Massachusetts had enacted legislation conforming the states to recommendations from CARB as of 2019, according to the agency.
