Carl Moyer Program

The Carl Moyer (Moyer) Program was established in 1998 as a partnership between the California Air Resources Board (CARB) and local air districts. The program provides monetary grants to private companies, and public agencies to purchase clean heavy‐duty engines beyond what is required by law and regulation through repowering, replacing, or retrofitting engines, vehicles, or equipment. The Moyer Program also funds infrastructure projects to support California’s transformation to zero and near‐zero emission technology. 

The  Moyer Program provides grant funding for the following project categories:

  • On-Road Projects (utility vehicles, school and transit buses)
  • Off-Road Projects (replacement for small fleets and exempt Agricultural Equipment)
  • Infrastructure Projects (projects including new battery charging and alternative fueling station installation)

The application period for the 2022 Moyer Program is now closed.

The 2023 Moyer Solicitation and Program documents will be available in February, and the application period will open in March 2023.
