Carl Moyer Program

carl moyer program 2

The Carl Moyer Program was established in 1998 as a partnership between the California Air Resources Board (CARB) and local air districts. This grant program provides funding for replacing, repowering, or retrofitting eligible heavy-duty engines with cleaner-than-required technology.

The Funding Agricultural Replacement Measures for Emission Reductions (FARMER) Program provides funding through local air districts for agricultural harvesting equipment, heavy-duty trucks, agricultural pump engines, tractors, and other equipment used in agricultural operations. The FARMER Program is supported in part by California Climate Investments, a statewide program that puts billions of Cap-and-Trade dollars to work.

The next application period for the Carl Moyer Program & FARMER Program is expected in the of Spring 2023. The applications below are for informational purposes and may be updated before the next application period.

The applications below can also be used during the application period for Community Air Protection (CAP) Incentives. The funding amounts and eligibilities in the CAP Incentives Guidelines will apply and override limits in the Carl Moyer Program applications.
