Advanced Clean Fleets Regulation Truck Regulation Implementation Group (TRIG)–Infrastructure Meeting 3

Registration now open for June 5, 2024

The Advanced Clean Fleets (ACF) regulation was adopted by California Air Resources Board (CARB) at the April 28, 2023, Board Hearing, and was effective on October 1, 2023 (California Code of Regulations, Title 13, Sections 2013, 2013.1, 2013.2, 2013.3, 2013.4, 2014,2014.1, 2014.2, 2014.3, 2015, 2015.1, 2015.2, 2015.3, 2015.4, 2015.5, 2015.6, and 2016). On August 22, 2023, staff conducted a kickoff meeting to seek feedback on the formation of a series of workgroups to assist in the implementation of the ACF Regulation. The first two TRIG meetings focusing on infrastructure were held on December 4, 2023, and March 11, 2024. Recordings of past Truck Regulation Implementation Group (TRIG) meetings are available on the ACF meetings and events website.

The ACF regulation complements CARB’s recently adopted Advanced Clean Trucks regulation and will help advance the introduction of zero-emission technologies into California’s truck and bus fleets requiring fleets to move to the cleanest available technology through requirements to both phase-in the use of ZEVs for targeted fleets and a 100 percent medium and heavy-duty zero-emission vehicle sales requirement in California, starting in the 2036 model year. The ACF regulation is expected to introduce 1,690,000 ZEVs into the California fleet by 2050. Additionally, the ACF regulation is expected to result in $26.5 billion in statewide health benefits from improved air quality and save fleet owners an estimated $48.0 billion through 2050.

The ACF Regulation is part of a comprehensive strategy to achieve the cleanest technology for truck and bus fleets by 2045 everywhere feasible and significantly earlier for market segments such as last mile delivery, public fleets, and drayage applications. Achieving California’s long-term air quality, climate, and public health goals will require a shift from the conventional combustion technologies to the cleanest available technology. Promoting the development and use of the cleanest technology  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 (AB) 32 (Nuñez, Chapter 488, Statutes of 2006), and SB 32 (Pavley, Chapter 249, Statutes of 2016), and AB 1279 (Muratsuchi, Chapter 337, Statutes of 2022). 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.
