The New Vehicle and Engine Certification Program is responsible for the certification of new engines, vehicles, powertrains, aerodynamic devices and other new certifications. Vehicles and engines may be sold and otherwise produced in California only if approved by Executive Order (EO) after review by CARB. Executive Orders are issued for on-road and off-road categories.
Scanned copies of issued Executive Orders may be requested via email.
CARB has issued Executive Orders for the following on-road heavy-duty vehicle, trailer, zero emission powertrain, and aero device categories and years. Additional certification information, summarized in the supplemental EO Summary files, is available for each category.
