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, UTVs, 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.
