Advanced Clean Fleets Regulation Effective January 2024

After years of debates, public hearings and regulatory proceedings, California’s Advanced Clean Fleets Regulation is set to take effect on January 1, 2024. Spearheaded by the California Air Resources Board (CARB), this rule is designed to safeguard the health of Californians by enhancing air quality and addressing the environmental impact of greenhouse gas emissions.

The regulation introduces zero-emission vehicle (ZEV) mandates for city-operated fleets. 

“As California ushers in the ACF Regulation, it is important that our Community Choice Aggregators (CCA) proactively adapt to the changing landscape,” said CalChoice Executive Director Jason Caudle. “Understanding the specific guidelines, leveraging available funding opportunities and actively participating in infrastructure development will be key to ensuring a smooth transition toward more sustainable fleets statewide.”

According to the policy, state and local governments’ fleets will have an acquisition requirement. Between 2024 to 2026, 50% of newly acquired medium and heavy-duty vehicles will need to be zero-emission.  Then, by 2027, all fleets must be fully converted to 100% zero-emission vehicles. California cities must also share information about their progress in transitioning their fleets with the California Air Resources Board (CARB) as part of new reporting requirements.

CalChoice associate members are eligible to apply for EV grants and funding opportunities through a range of programs, including:

Other EV grant funding programs are listed on the U.S Department of Energy’s website. 

“It makes me excited to see California adopting innovative legislation and regulation to improve our air quality and environment,” continued Jason. “Through this new policy, our CCAs and municipalities will be able to actively contribute to the state’s environmental goals.”
