Background

CORE is a project intended to encourage California fleets to purchase or lease zero-emission off-road equipment. CORE provides a streamlined voucher process by which potential purchasers can receive funding to help offset the higher cost of such equipment. The CORE project provides vouchers for several categories of heavy-duty off-road zero-emission equipment such as freight, construction, agricultural, and commercial harbor craft. More information about the CORE program is available.
