California Continues Expanding ZEV Programs

The State of California has awarded $500 million to school districts and other educational agencies to buy zero-emission school buses and chargers. Zero-emission school buses are part of the state’s relentless move to a clean-energy future and lead to better health for students and communities. California’s transition to zero-emission transportation is also accelerating with support from the state’s Clean Truck and Bus Voucher Incentive Project (HVIP). Funded primarily with proceeds from the Cap-and-Trade Program, HVIP underwent 177% year-over-year growth in 2024. This February, more than 200 HVIP-funded zero-emission trucks and buses were deployed with $31 million in incentives. The incentive program is a collaboration between the California Air Resources Board (CARB)* and the California Energy Commission (CEC), and is administered by CALSTART, a non-profit transportation organization.

“Cleaning up the state’s school bus fleet is central to California’s efforts to provide clean transportation in priority communities that are disproportionately hurt by air pollution,” said California Air Resources Board Chair Liane Randolph. “The vast majority of these grants will go to local educational agencies that serve these communities.”

School Buses

Zero-emission school buses play a key role in California’s efforts to achieve carbon neutrality by 2045 and help protect children who are particularly vulnerable to the health impacts from diesel exhaust. In California, all school bus purchases made by school districts will need to be zero-emission technology by 2035, with an extension until 2045 for frontier local educational agencies in rural communities.

  • The time children spend in school bus commutes accounts for less than 10% of a child’s day, yet the commutes have been found to contribute up to 33% of a child’s daily exposure to some air pollutants in a diesel-fueled school bus, according to a 2003 study funded by CARB.
  • To date, California has provided more than $1.3 billion in incentives to school districts, funding more than 2,300 zero-emission school buses, of which 1100 are already in use. More than 70% of the zero-emission school buses in use are in the state’s most pollution-burdened communities. More than 300 California school districts and local education agencies have purchased at least one zero-emission school bus, and a few have made the switch to a 100% clean fleet.
  • The school buses in this round of grants are expected to reduce 18,000 metric tons of greenhouse gas emissions annually – equivalent to taking more than 4000 cars off the road for a year.

Clean Truck and Bus Vouchers

Trucks total just six percent of vehicles on California’s roads. However, they account for more than 35% of the state’s transportation emissions and a quarter of the state’s on-road greenhouse gases. Incentives are critical for supporting the advancement and wide-scale deployment of zero-emission vehicle (ZEV) technologies while providing immediate emission reductions to help meet air quality and climate goals. HVIP was launched to provide point-of-sale discounts, making zero-emission trucks and buses more accessible for fleets and businesses. Over 15 years, HVIP invested $754 million, helping 2000 fleets deploy 10,000 clean trucks and buses. These vehicles have logged 340+ million miles while significantly cutting emissions statewide.

  • HVIP (the state’s Clean Truck and Bus Voucher Incentive Project)is expanding access and affordability, with public agencies and small businesses making up 81% of ZEV orders.
  • More than 5000 HVIP-funded ZEVs are in production to meet surging demand.
  • The program continues to grow, adding manufacturers, dealers, and 167 advanced vehicle models.
  • Several HVIP funding categories have reached capacity, but funding remains available through the transit set-aside and Innovative Small e-Fleets (ISEF) project. Fleets should apply while funds last.

California’s Zero-Emission Truck and Bus Market

  • Sales of new zero-emission trucks, buses and vans doubled in 2023 over the previous year, representing one out of every six new vehicles sold for services including last-mile delivery, freight transportation, and school buses.
  • 16,327 charging and hydrogen fueling points for zero-emission trucks and buses are installed across the state.
