The California Air Resources Board (CARB) in partnership with CALSTART launched the Hybrid and Zero-Emission Truck and Bus Voucher Incentive Project (HVIP) and Low NOx Engine Incentives in 2009 to accelerate the purchase of cleaner, more efficient trucks and buses in California.

The greatest barrier to purchasing cleaner trucks and buses is the higher price tag.

HVIP provides point-of-sale discounts to vehicle purchasers. There’s no waiting for a rebate check or a tax credit. HVIP works closely with truck and bus dealers to apply the voucher incentive at the time of purchase.

Why do we need cleaner trucks and buses?

Today, trucks and buses are responsible for 37 percent of California’s greenhouse gas and criteria emissions. By deploying new electric, hybrid, and natural gas trucks and buses, fleets can help reduce these emissions.
