What does it fund?

The replacement of old, high-polluting vehicles, engines, and equipment, with new technologies that are cleaner than required, or earlier than required by, rules and regulations. Grant amounts are based on the cost-effectiveness of harmful pollutants that will be reduced by the project and may also fund the installation of charging and fueling infrastructure.

Who is eligible for funds?

Individuals, businesses, and government agencies are eligible for funding. Local air districts administer the program and select projects to fund, not every air district funds every type of project that is eligible, contact your local air district for the most updated information.

Are there recent policy changes?

The Carl Moyer Program was modified by the California legislature in 2015 through Senate Bill 513. The bill updated the Moyer Program to be able to better support advanced technologies including associated charging and fueling infrastructure, and also expanded the Program's ability to stack its funds with other State incentive dollars, thereby extending the reach of both pots of funds. The Board approved a new set of Guidelines to match in April 2017. 

How does this program provide benefits to priority populations?

Local air districts with a population greater than 1,000,000 people must invest at least 50 percent of their Moyer program funds in projects within “environmental justice areas.” These areas are determined by the local air districts, based on similar criteria to those used to designate priority population boundaries.

How do I access funds?

Air districts administer and select projects for their region according to their local priorities. To access funds, apply through your local air district.
