In 2020, the California Air Resource Board launched the Clean Off-Road Equipment Voucher Incentive Project (CORE), which offers vouchers of up to $500,000 per vehicle for businesses interested in buying or leasing clean, heavy-duty, off-road equipment through the program. Equipment includes zero-emission terminal tractors, railcar movers, and transport refrigeration units, among others. Additional funding is available for facilities that deploy clean technology in communities overburdened by pollution and for infrastructure connections, the agency also said.
