California’s Hybrid and Zero-Emission Truck and Bus Voucher Incentive Project (HVIP), launched in 2009, accelerates commercialization of zero-emission and near-zero-emission technologies by providing point-of-sale vouchers to make advanced vehicles more affordable. Of the 730 zero-emission trucks on the road in California as of January 2022, more than 60% are directly funded by HVIP.
In 2018 alone, HVIP received $176 million in requests—more than all 8 previous years combined. Requests in 2021 totaled more than $240 million.

All vehicles eligible for HVIP are required to be certified at the vehicle level. Zero-Emission Powertrain Certification (ZEPCert) will be an additional requirement for all new HVIP vehicle eligible applications submitted to the California Air Resources Board (CARB) on or after 1 January 2023, for all applicable zero-emission powertrains and the trucks and buses in which they are installed.
CARB is encouraging manufacturers to start the process of obtaining this certification in advance of the deadline.
