What you need to know: California’s incentive program for medium- and heavy-duty trucks and buses has delivered more than $1 billion in funding to fleets statewide, supporting thousands of clean truck and bus purchases and reducing emissions while improving air quality in communities most affected by air pollution. The program continues to support clean transportation in California, and with demand at an all-time high, underscores the program’s impact statewide.

SACRAMENTO — The California Air Resources Board (CARB) announced today that California’s Clean Truck and Bus Voucher Incentive Project (HVIP) has delivered more than $1 billion in funding to California fleets — supporting more than 2,000 fleets, enabling the deployment of 11,600 clean vehicles, and accumulating 181 million miles statewide.

“Reaching $1 billion in funding for clean trucks and buses marks a major milestone for California’s efforts to reduce harmful pollution,” said CARB Chair Lauren Sanchez. “It shows that our efforts are delivering real results — improving air quality, supporting businesses, and reducing pollution in communities most impacted by freight and transportation emissions.”

Administered by CALSTART on behalf of CARB, HVIP has been instrumental in advancing the deployment of zero-emission technologies, reducing emissions from traditional trucks and buses, and improving air quality in communities across California.

The program continues to anchor California’s clean transportation adoption, and demand continues to surge — nearly $200 million in incentive requests were submitted on the first day of the September 2025 funding round, followed by an additional reopening in December 2025. Funding remains available, and fleets are encouraged to apply through participating dealers.

Launched in 2009 and primarily funded with Cap-and-Invest dollars through California Climate Investments, HVIP helps fleets and businesses realize the benefits of zero-emission vehicles through point-of-sale discounts. The program offers a wide range of zero-emission medium- and heavy-duty vehicles, including Class 2b–8 trucks, transit buses, school buses, and shuttle buses, with additional options available for small trucking fleets through the Innovative Small e-Fleet (ISEF) set-aside.

California remains steadfast in working with manufacturers to accelerate zero-emission transportation, protect consumer choice, and cut harmful air pollution, despite federal market uncertainties.
