Available Voucher Funds

The California Air Resources Board (CARB), in partnership with CALSTART, launched the Clean Off-Road Equipment Voucher Incentive Project (CORE) to accelerate the purchase of zero-emission off-road equipment in California.

CORE, analogous to the Hybrid and Zero-Emission Truck and Bus Voucher Incentive Project (HVIP), is a project intended to promote the purchase of off-road freight and other heavy-duty off-road vehicles and equipment powered by zero-emission technology by offering vouchers that help offset the higher costs of such equipment. Because CORE is designed to support the expansion of zero-emission operations among California’s off-road fleets, it benefits Californians through reductions in air pollution and greenhouse gas emissions. Additionally, the program helps deploy and advance critical technologies necessary for California to meet its long-term air quality and climate goals.

In FY 2024-25, CARB allocated $13.9 million to support the Clean Off-Road Equipment (CORE) Project’s Heavy-Duty Voucher program, which helps offset the higher costs of zero-emission off-road equipment. In addition to this new allocation, approximately $22 million in unredeemed voucher funds from previous cycles will be reallocated to support upcoming funding opportunities. These combined funds will help expand access to cleaner technologies across industries and accelerate the transition to zero-emission equipment in California.

CORE will stop accepting voucher request applications for heavy-duty off-road equipment purchases as of November 19, 2025, at 9:00 a.m. PT.
