HVIP is designed to make sales happen. Vouchers directly benefit purchasers and dealers – helping close the price gap between advanced technology vehicles and their conventionally fueled counterparts.

HVIP is helping speed the pace of technology transformation. In 2018 alone, HVIP received $176 million in requests – more than all 8 previous years combined. Requests in 2021 alone totaled more than $240 million.

Of the 730 zero-emission trucks on the road in California as of January 2022, more than 60% are directly funded by HVIP.

Building the Green Economy to Meet Climate Goals

HVIP is a key component of the California Air Resources Board’s Low Carbon Transportation and Air Quality Improvement Program, funding the technologies needed to meet California’s 2030 and 2050 climate goals.

HVIP’s decade of success exemplifies how government and industry are working together to reduce emissions in new and visionary ways; achieving cleaner air in the most vulnerable communities, and statewide; and creating a pathway for sustainable transportation in California and beyond. These efforts are rooted in obtaining meaningful progress on climate goals while creating jobs and boosting economic competitiveness. As of 2021, incentive dollars invested through HVIP have created nearly 3,000 jobs and spurred another nearly 9,000 jobs from private investment.
