California’s ZEV regulation requires automobile companies to produce a certain percentage of ZEVs for sale in California, such as hydrogen fuel cell, batter electric, and hybrid vehicles. The ZEV mandate requires automakers to sell 15.4% ZEVs of their 2025 new vehicle sales fleet. Twelve other states (Colorado, Connecticut, Maine, Maryland, Massachusetts, New Jersey, New York, Oregon, Rhode Island, Minnesota, Washington, and Vermont) and the District of Columbia have adopted the ZEV crediting requirements that California imposes on automakers. The Multi-State ZEV Task Force serves these 12 states plus DC, and has proposed a Multi-State ZEV Action Plan for 2018-2021, including actions to advance ZEV deployment through consumer education and outreach, charging infrastructure, purchase incentives, light duty fleets, and targeting dealerships. It is a model program for states to adopt to go beyond federal CAA regulation.
