Zero Emission Vehicle (ZEV) Production Requirements
The California Air Resources Board (CARB) certifies new passenger cars, light-duty trucks, and medium-duty passenger vehicles as ZEVs if the vehicles produce zero exhaust emissions of any criteria pollutant (or precursor pollutant) under all possible operational modes and conditions. Manufacturers with annual sales between 4,501 and 60,000 vehicles may comply with the ZEV requirements through multiple alternative compliance options that include producing low emission vehicles and obtaining ZEV credits. Manufacturers with annual sales of 4,500 vehicles or less are not subject to this regulation.
CARB’s emissions control program for MY 2017 through 2025 combines the control of smog, soot, and greenhouse gases (GHGs) and requirements for ZEVs into a single package of standards called Advanced Clean Cars. In December 2012, CARB finalized new regulatory requirements that allow vehicle manufacturer compliance with the U.S. Environmental Protection Agency’s GHG requirements for MY 2017-2025 to serve as compliance with California’s adopted GHG emissions requirements for those same model years.
The accounting procedures for MY 2018-2025 are based on a credit system as shown in the table below. The minimum ZEV requirement for each manufacturer includes the percentage of passenger cars and light-duty trucks produced by the manufacturer and delivered for sale in California. The regulation also includes opportunities for compliance with transitional zero emission vehicles, which must demonstrate certain exhaust emissions standards, evaporative emissions standards, on-board diagnostic requirements, and extended warranties.
