July 30, 2019—Colorado and major automakers said on Monday they have reached a deal on the state’s plan to adopt California’s zero-emission vehicle (ZEV) requirements, reported Reuters.

The state, which plans to join the California program starting with the 2023 model year, has agreed to allow automakers to earn credits for selling electric vehicles in the two model years prior and use other transitional credits available in other states. 

Major auto trade groups including General Motors, Volkswagen, Toyota and Hyundai said the state agreed to address concerns “by providing the support Coloradans need to buy electric vehicles while allowing auto manufacturers to transition into Colorado’s ZEV program.”

The agreement must be approved by the state's Air Quality Control Commission at a meeting later this month.
