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.

Upon its inception a decade ago, HVIP had an immediate impact on the market: From 2010-2012, nearly half of hybrid and zero-emission trucks and buses in the U.S. were purchased through HVIP. And that impact has grown: In 2018 alone, HVIP received $176 million in requests – more than all 8 previous years combined.

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. The value of the voucher enhancement is 10% plus-up of the voucher amount, up to $15,000.

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).

Cleaner-than-diesel miles traveled in California by HVIP-funded vehicles, 2010 to 2020.

58% of Vouchers

have funded vehicles deployed in Disadvantaged Communities.

28% of U.S. Greenhouse Gas Emissions

are generated by the transportation sector, according to the U.S. EPA – the most of any sector. In California, medium- and heavy-duty on-road vehicles account for just 7% of all registered vehicles but 32% of NOx Emissions, according to CARB's 2020 Mobile Source Strategy.

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, which is focused on supporting the advanced 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 diesel 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.
