Carl Moyer Program (Heavy-Duty Engines)


The Carl Moyer Program is currently not accepting applications.
The program 
will re-open in Spring of 2023.

if you have already applied to our 2022 On-Road Program, please continue to log on to the portal to view your application status.


The purpose of the CMP is to obtain emission reductions of Nitrogen Oxides (NOx), Particulate Matter (PM10) and Reactive Organic Gases (ROG) from heavy-duty vehicles and other equipment operating in California as early and as cost-effectively as possible. The CMP provides financial incentives to assist in the purchase of cleaner-than-required engine and equipment technologies to achieve emission reductions that are real, surplus, quantifiable and enforceable. 

CMP funding is provided via two legislative bills, SB 1107 and AB 923.  SB 1107 provides approximately $61 million per year in statewide funding, and AB 923 permits air districts in designated non-attainment areas to collect an additional two dollars in vehicle registration fees to expend on programs to reduce emissions from vehicular sources and off-road equipment. A resolution approving such fees was adopted by the South Coast AQMD Board on December 3, 2004. 

The Carl Moyer Program fills a critical niche in California’s strategy to achieve clean air.  In the past 22 years, the CMP has provided $530 million in funding which has resulted in approximately 8,601 tons per year of NOx and over 249 tons per year of PM emission reductions throughout South Coast AQMD.

What's New
AB 1274 (O’Donnell) was signed by the Governor in October 2017 and resulted in the postponement of smog checks on new vehicles from Years 6 to 8, starting on January 1, 2019.  A fee of $25 per year the vehicle is exempted from smog check will be charged by DMV, and the revenues from the fee will be directed to the CMP.  As a result of AB 1274, the funding for this year’s CMP to be administered by the South Coast AQMD was increased by about $4.3 million. 

The South Cost AQMD expects to receive additional funds for this year’s Carl Moyer Program, which may include funds in support of the Community Air Protection Program (CAPP) and Funding Agricultural Replacement Measures for Emission Reductions (FARMER) Program.

Each project will be evaluated in accordance with the latest version of the Funding Guidelines for Agencies that Administer California Climate Investments established by the California Air Resources Board, including the CalEnviroScreen tool, to identify those projects that are located within a disadvantaged and/or low-income community.  To see if a particular community is within a disadvantaged or low income community, please visit: to external website. 

Applicants must comply with all federal, state, and local laws, ordinances, codes and regulations. If the application is eligible for funding, all vehicles and/or equipment to be purchased, leased or installed must be compliant with all applicable federal, state, and local air quality rules and regulations, and will maintain compliance for the full Contract term.
