As of the end of 2023, the HVIP portfolio stands at over $1 billion invested across California. Funding requests in 2022 alone totaled more than $240.3 million.

Public Health

A Disadvantaged Community (DAC) is an area in California that is especially vulnerable to the impacts of climate change because of socioeconomic and geographic factors. HVIP provides increased voucher incentive amounts for vehicles domiciled within DACs.

Offsetting diesel miles has health benefits related to reducing harmful pollutants such as NOx (linked to asthma) and Particulate Matter (linked to premature death in people with heart or lung diseases, as well as asthma and decreased lung function).

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 June 2022, incentive dollars invested through HVIP have created nearly 3,500 jobs and spurred another nearly 11,000 jobs from private investment.
