California's ZEV credits are
California's ZEV credits are sold by manufacturers of Zero Emission Vehicles to other car manufacturers who produce primarily gasoline-powered vehicles. ZEV credits are not paid with tax dollars! California requires auto manufacturers to sell a certain percentage of zero emission vehicles. If they don't, they must purchase ZEV credits from a manufacturer who does. Any car manufacturer willing to produce enough zero emission cars can make money selling ZEV credits.
