Washington’s Zero-Emission Incentive Program (WAZIP)

Learn how to get discounts on zero-emission medium- and heavy-duty vehicles and off-road equipment.

The Washington Zero-Emission Vehicle Incentive Program (WAZIP) launched in 2025 to help more businesses switch to commercial medium- and heavy-duty zero-emission vehicles and equipment. Funded by the Climate Commitment Act and managed by the Washington State Department of Transportation, and administered by CALSTART, the program provides point-of-sale discounts to make cleaner vehicles more affordable. WAZIP follows recommendations from a 2024 state study, is modeled after California’s successful HVIP (Clean Truck and Bus Voucher Program) and CORE (Clean Off-Road Equipment Voucher) programs. It directly supports Washington’s climate and equity goals by cutting transportation emissions and making the benefits of clean technology more accessible.

What is WAZIP 

WAZIP is a new point-of-sale voucher program that lowers the cost of zero-emission vehicles and commercial equipment right at purchase—so buyers don’t have to wait for rebates or file extra paperwork. It applies to medium- and heavy-duty vehicles and off-road commercial equipment, helping fleets replace older, higher-polluting vehicles with cleaner options. Dealers handle the paperwork and customers see the savings immediately, making it easier and faster to transition to zero-emission technology.
