Hybrid and Zero-Emission Truck and Bus Voucher Incentive Project (California HVIP)


The Hybrid and Zero-Emission Truck and Bus Voucher Incentive Project (HVIP) and Low NOx Engine Incentives was formed by the California Air Resources Board (CARB) as a result of the Air Quality Improvement Program (AQIP) following the passing of the California Alternative and Renewable Fuel, Vehicle Technology, Clean Air, and Carbon Reduction Act of 2007 (AB 118, Statutes of 2007, Chapter 750). AQIP offers funding for projects and initiatives focused on supporting the development and deployment of the advanced technologies needed to meet California’s longer-term, post-2020 air quality goals. The fuel efficiency and zero- to low-emission benefits of zero-emission, hybrid, and natural gas vehicle technologies provide a strong public health benefit by reducing harmful greenhouse gas (GHG) and criteria emissions.

Growing California’s Market for Clean Vehicle Technologies

HVIP responds to a key market challenge by making clean trucks and buses more affordable for fleets.  By offering point-of-sale incentives for clean trucks and buses, HVIP provides a streamlined approach for providing helpful incentives to fleets without waiting to submit proposals or complicated paperwork. Fleets receive the voucher discount at the point of sale while HVIP-approved vendors and dealers process the required documentation.

This innovative approach provides a meaningful “kick-start” to the low-carbon clean truck and bus industry. HVIP helps fleet and vehicle owners move into clean trucks and buses faster, while reducing emissions, fuel consumption and supporting California’s goals to promote a clean climate future.

HVIP is Making a Difference

To date, HVIP has deployed more than 2,700 medium- to heavy-duty vehicles, accelerating the growth of the nation’s early market of zero-emission and hybrid trucks and buses by 30 percent. HVIP has successfully increased the demand of these technologies which is proving to advance the industry, create jobs and economic benefits while accelerating the commercialization of these trucks and buses for all. With more than 1,000 fleets participating across California, HVIP is helping the state meet its clean air goals.

HVIP is administered and implemented through a partnership between California Air Resources Board (CARB) and CALSTART (selected by CARB via a competitive grant solicitation).
