A Partial Zero Emissions Vehicle is a vehicle that has zero evaporative emissions from its fuel system, has a 15 year (or at least 150,000 mile) warranty and meets SULEV tailpipe emission standards.PZEVs have their own administrative category within the state of California for low emission vehicles.This vehicle category was created as part of a bargain with the California Air Resources Board (CARB), so that the automobile manufacturers could postpone producing mandated zero emission vehicles (ZEVs), which will require the production of electric vehicles or hydrogen fuel cell vehicles.
