P-ZEV

P-ZEV means "partially zero emission vehicle" in the United States. A vehicle is certified as one if it has cleared the strict standard for gas emissions, although it is not as good as an electric vehicle (BEV) or a fuel cell electric vehicle (FCEV). Since 2003, it has been obligatory to sell a certain proportion of "vehicles with zero airborne particle emissions" promoted by the California government ", and some ULEVs (ultra-low emission vehicles) and hybrid electric vehicles (HEVs) correspond to this.
