California Air Resources Board

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. Affected entities had to report applicable information through the CARB Large Entity Reporting portal by May 1, 2021.

Reporting is now closed.

Entities had to report if in 2019 they operated a facility in California and met any of the following criteria:

• Had gross annual revenues greater than $50 million in the United States for the 2019 tax year, including revenues from all subsidiaries, subdivisions, or branches, and had one or more vehicles over 8,500 lbs. GVWR under common ownership or control that were operated in California in 2019; or
• Any fleet owner in the 2019 calendar year that had 50 or more vehicles over 8,500 lbs. GVWR under common ownership or control; or
• Any broker or entity that dispatched 50 or more vehicles over 8,500 lbs. GVWR into or throughout California, in the 2019 calendar year; or
• Any California government agency including all state and local municipalities that had one or more vehicles over 8,500 lbs. GVWR that were operated in California in 2019; or 
• Any federal government agency that had one or more vehicles over 8,500 lbs. GVWR that were operated in California in 2019.

Reporting was not required for:

• K-12 schools and school districts and other entities whose fleet is comprised primarily of school buses as defined in the California Vehicle Code section 545, which for the purposes of this regulation, means the registered owner, lessee, licensee, school district superintendent, or bailee of any school bus, who operates or directs the operation of any such bus on either a for-hire or not-for-hire basis; or
• Transit vehicles that are subject to the Innovative Clean Transit regulation, 13 CCR section 2023, and their vehicles that used exclusively to support transit service; or
• Light-duty vehicles dispatched but not owned by transportation network companies; or
• Military tactical vehicles as described in 13 CCR section 1905 and military tactical facilities owned or operated by the United States Department of Defense and/or the United States military services; or
• Vehicles awaiting sale as defined in section 2012(d)(23); or
• Emergency vehicles as defined in the California Vehicle Code section 165.

This is a summary of the data collected through the one-time reporting requirement of the Advanced Clean Trucks regulation. The data was collected in 2021 from fleets, government agencies, brokers, and other businesses through an online portal that was established by the CARB. The survey included questions on vehicles that were owned by the respondents and about vehicles that were dispatched but not owned by the respondents.

Information collected through the survey is being used to assist CARB in developing policies and recommendations to accelerate a large-scale transition to zero-emission medium-and heavy-duty vehicle fleets.

The results are available in aggregated form in two separate formats. The first is a printable PDF document providing statewide aggregated results showing the original question and responses in tables or graphs in the same order the questions were asked in the survey. The second is an Excel spreadsheet that groups the results by air basin in three tabs.

• Statewide Aggregated Data 
• Air Basin Aggregated Data 

A total of 1,866 entities reported, consisting of 7,767 facilities, for a total of 386,286 vehicles. The data collected is consistent with CARB’s reporting estimates calculated prior to conducting the survey, corroborates CARB’s research, and provides additional fleet information to support the proposed Advanced Clean Fleets rule.

The data is being released in an aggregated/anonymized format. This is because the raw data contains confidential/proprietary information about the reporting entities.
