Zero-Emission Vehicle
A vehicle that produces no exhaust emissions at the point of use — battery-electric and hydrogen fuel-cell vehicles — as defined in vehicle emissions regulation.
Definition
A zero-emission vehicle is one that emits no regulated pollutants or carbon dioxide from its tailpipe during operation. The category originates in California's ZEV programme, which requires manufacturers to sell rising shares of ZEVs, and includes battery-electric and hydrogen fuel-cell vehicles; plug-in hybrids typically receive partial credit under separate rules.
