Large Entity One-Time Reporting

The California Air Resources Board (CARB) adopted a regulation in June 2020 that has a one-time reporting requirement for large entities that operate or dispatch vehicles with a manufacturer’s gross vehicle weight rating (GVWR) greater than 8,500 lbs. in California. It includes medium duty vehicles like vans and ¾-ton pickups such as the F250 or Ram 2500 and heavier vehicles of all configurations and fuel types, but does not apply to lighter vehicles like cars and light duty pickups.

CARB submitted the Advanced Clean Trucks regulation to the Office of Administrative Law (OAL) for review and approval on January 29, 2021, and OAL approved the regulation on March 15, 2021. In light of the relatively short time period between OAL’s approval of the regulation and the April 1, 2021 deadline to report the above mentioned information, CARB is providing affected entities the compliance flexibility to report applicable information through the CARB Large Entity Reporting portal by May 1, 2021.
