Updated Draft Regulatory Text for the Advanced Clean Fleets Regulation Now Available for Public Comment

The California Air Resources Board (CARB) has released updated draft regulation language for the Advanced Clean Fleets regulation to be discussed at the workshop series scheduled for May 2, 4, and 6. The draft regulation text and workshop bulletin are available at the Advanced Clean Fleets Meetings & Events website.

The updated regulation text incorporates changes from prior comments and is organized in the following four sections:

  1. High Priority and Federal Fleet
  2. State and Local Government Fleets
  3. Drayage Trucks
  4. 100 Percent ZEV Sales

Please submit written informal public comments on the updated regulation text by using the comment submittal form. Please submit comments as soon as possible after the workshops to provide CARB staff with the best opportunity to consider changes and meet with stakeholders. Informal comments already received can be viewed on the workshop comment log.

ACF Meetings & Events

Additional meeting materials may be made available in advance of the workshop and will be posted on the Advanced Clean Fleets Meetings & Events website.


CARB staff previously held a series of public workshop meetings in October to November of 2021 to receive feedback and suggestions on the initial draft of the proposed ACF rulemaking language and inventory. These workshops were followed by a series of workgroup meetings from December 2021 to March 2022 to discuss infrastructure.

Achieving California’s long-term air quality, climate, and public health goals will require a transition from the conventional combustion technologies to zero-emission everywhere feasible and near-zero-emission powered by clean, low-carbon renewable fuels everywhere else. Promoting the development and use of zero-emission trucks will contribute to the goals set by the Governor’s Executive Order N-79-20 and the Sustainable Freight Action Plan, and will help achieve emission reductions as outlined in the State Implementation Plan, Senate Bill (SB) 350 (de León, Chapter 547, Statutes of 2015), Assembly Bill 32 (Nuñez, Chapter 488, Statutes of 2006), and SB 32 (Pavley, Chapter 249, Statutes of 2016). This effort is part of a broader strategy to increase clean, affordable transportation options such as zero-emission technologies, innovative methods to improve freight activity, and efficiency of transportation systems in California
