California Air Resources Board

The California Air Resource Board (CARB) has adopted many fleet rules that effect on-road heavy-duty vehicles. The Carl Moyer Memorial Air Quality Standards Attainment (Carl Moyer) Program provides incentive grants for cleaner-than-required engines, equipment, and other sources of pollution providing early or extra emission reductions. These grants are issued locally by air pollution control districts and air quality management districts. Implementing air districts determine local funding and availability of Carl Moyer Program projects. Please contact your local air district for current information on funding availability, project eligibility, applications, and application selection timeline. On-road project categories include heavy-duty truck and buses, school buses, transit vehicles, drayage trucks, public agency and utility vehicles, emergency vehicles, and solid waste collection vehicles. On-road infrastructure projects such as electrical charging and alternative fuel stations for light, medium, and heavy-duty trucks may also be eligible for funding. In addition, infrastructure for truck stop electrification, TRUs, transit vehicles, emergency vehicles, and school buses may also be eligible for funding.
