Carl Moyer Memorial Air Quality Standards Attainment Program

The Carl Moyer Memorial Air Quality Standards Attainment Program is CARB’s long-running grant route for cleaner-than-required engines, equipment, and other air-pollution sources in California. It runs jointly with 35 local air districts and covers on-road heavy-duty trucks, off-road equipment, marine vessels, locomotives, and stationary agricultural pump engines. Funding comes from state DMV registration surcharges, tire fees, and local district matches, with historical statewide spending around $60 million to $100 million a year. Applications go through the local air district, which administers grants and selects projects, so the award path is regional rather than centralized. District contacts and local review shape timing, eligibility, and project selection across the state. Carl Moyer is strongest for fleets and equipment owners that can show a clear emissions benefit and work through a district-approved project list. The program spans transportation, marine, and agricultural equipment, which makes it a broad CARB option for operators trying to run cleaner than the current regulatory floor.
