California Low NOx Engine Vouchers Available Now


The California Air Resources Board (CARB) is now accepting new vouchers for all categories of the Hybrid and Zero-Emission Truck and Bus Voucher Incentive Project (HVIP). CARB, in partnership with CALSTART, launched the HVIP program in 2009 to accelerate the purchase of cleaner, more efficient trucks and buses in California. HVIP provides incentives for zero-emission and hybrid trucks, buses and low NOx natural gas engines like the Cummins Westport ISL-G Near Zero NOx emissions natural gas engine.

HVIP is part of California Climate Investments, a statewide program that puts billions of cap-and-trade dollars to work reducing greenhouse gas emissions, strengthening the economy and improving public health and the environment. The cap-and-trade program also creates a financial incentive for industries to invest in clean technologies and develop innovative ways to reduce pollution. At least 35 percent of these investments are made in disadvantaged and low-income communities.
