SACRAMENTO — California’s transition to zero-emission transportation is accelerating faster than ever thanks to support from the state’s Clean Truck and Bus Voucher Incentive Project (HVIP).  

Funded primarily with proceeds from the Cap-and-Trade Program, HVIP experienced 177% year-over-year growth in 2024. This February alone, more than 200 HVIP-funded zero-emission trucks and buses were deployed with $31 million in incentives. 

How We Got Here 

• HVIP was launched to provide point-of-sale discounts, making zero-emission trucks and buses more accessible for fleets and businesses. 

• Over 15 years, HVIP invested $754 million, helping 2,000 fleets deploy 10,000 clean trucks and buses. 

• These vehicles have logged 340+ million miles while significantly cutting emissions statewide. 

• While trucks total just six percent of vehicles on California’s roads, they account for over 35% of the state’s transportation emissions and a quarter of the state’s on-road greenhouse gases. 

• Incentives are critical for supporting the advancement and wide-scale deployment of zero-emission vehicle (ZEV) technologies while providing immediate emission reductions to help meet air quality and climate goals. 

What’s Next 

• HVIP is expanding access and affordability, with public agencies and small businesses making up 81% of ZEV orders. 

• Over 5,000 HVIP-funded ZEVs are in production to meet surging demand. 

• The program continues to grow, adding manufacturers, dealers, and 167 advanced vehicle models. 

• Several HVIP funding categories have reached capacity, but funding remains available through the transit set-aside and Innovative Small e-Fleets (ISEF) project. Fleets should apply while funds last. 

California’s Zero-Emission Truck and Bus Market  

• Sales of new zero-emission trucks, buses and vans doubled in 2023 over the previous year, representing one out of every six new vehicles sold for services including last-mile delivery, freight transportation, and school buses. 

• 16,327 charging and hydrogen fueling points for zero-emission trucks and buses are installed across the state.
