The California Air Resources Board (CARB) on Feb. 15 initiated the second year of grants totaling $19 million for hybrid vehicle technology that significantly reduces smog-forming and greenhouse gas emissions.

The Hybrid Truck and Bus Voucher Incentive Program will provide vouchers on a first-come, first-served basis to help California fleets purchase fuel-efficient hybrid medium- and heavy-duty vehicles.

At least $2 million of these funds will be set aside for California public fleets to increase the number of hybrid vehicles.

“This program created an opportunity for California businesses to upgrade their trucks and proves that there is demand for technology that provides clean and fuel efficient vehicles,” said CARB Executive Officer James Goldstene, in a written statement.

Interested public and private fleets can reserve a voucher for up to $40,000 through a participating dealership at the time the vehicle is ordered. The voucher is then redeemed at the time of purchase.

The program is part of the Air Quality Improvement Program, established in 2007 by AB 118 (Nunez) to provide funding for advanced technology vehicles and equipment.

CARB’s voucher program is implemented by CALSTART, a non-profit organization that works with business, fleets and government to develop and implement clean, efficient transportation solutions.

Last year, CARB provided about $20 million to help California fleets purchase more than 650 hybrid trucks and buses. Almost half the vouchers were for urban beverage-delivery vehicles and about 20 percent for package-delivery vehicles. Hybrid technology is similar to that used in cars and helps reduce smog-forming and greenhouse gas emissions and also provide fuel economy benefits, particularly in vehicles that require heavy-stop-and-go operation or idling.
