Vehicle emissions contribute to unhealthy levels of ozone, also known as "smog," and particulate matter.

In the Bay Area, tailpipe emissions from the transportation sector account for approximately 40 percent of the criteria air pollutants and greenhouse gases, or GHGs, emitted. Significant emissions reductions from the on-road transportation sector are key to helping the Bay Area attain state and federal ambient air quality standards and GHG emission reduction targets.

In 1991, the California State Legislature authorized the Department of Motor Vehicles, or DMV, to impose a $4 surcharge on cars and trucks registered within the Air District’s jurisdiction to provide grant funding to eligible projects that reduce on-road motor vehicle emissions. The statutory authority for the Transportation Fund for Clean Air, or TFCA, and requirements of the program are set forth in California Health and Safety Code Sections 44241 and 44242. 

Sixty percent of TFCA funds are awarded by the Air District through the TFCA Regional Fund, and to eligible programs implemented directly by the Air District, referred as Air District-sponsored programs. Each year, the Air District’s Board of Directors considers the allocation of new TFCA funds and the proposed updates to the policies. Solicitations and Call for Projects are issued following the Board’s approval.

The remaining forty percent of this funding is passed through to the designated agencies of the nine Bay Area counties through the TFCA 40 Percent Fund and is awarded by these agencies to TFCA-eligible projects located within those counties.

Public Comment Period Open for TFCA Regional Fund Policies Commencing FYE 2025

The Air District is currently accepting public comments for the TFCA Regional Fund Policies and Evaluation Criteria. Based on input from stakeholders, Air District staff will prepare a final draft of the proposed updates to the Regional Fund Policies for consideration by the Air District’s Board of Directors at a meeting that is tentatively scheduled for June 2024. The adopted Regional Fund Policies will govern the use of the TFCA Regional Funds starting from July 1, 2024, for a year or more.

The draft Policies and Evaluation Criteria (redlined changes from FYE 2024) is available in the “Resources” section on this page.


Interested parties are strongly encouraged to view the webinar before submitting comments.
