Tribal Relations

CARB regulates air pollution. Actions to implement the Clean Air Act, California’s Global Warming Solutions Act, and related laws have achieved dramatic reductions in air pollution, preventing hundreds of thousands of cases of serious health effects each year. Despite the dramatic progress to date, air pollution and climate change continue to threaten human health and welfare.

Tribal communities are the original inhabitants of California and have a unique relationship to the land and natural resources. Tribes communicate with local, state, and federal governments to address issues concerning tribal self-governance and tribal resources. Each tribe is distinctly different in its geography, culture, history, governance structure, and language. CARB is committed to improving communications and working relationships with Tribes. The following Tribal Activities Reports outline CARB's work with Tribes:

Overview of CARB Programs

CARB participates in the CalEPA Tribal Advisory Committee (TAC) meetings. Each meeting pertains to a specific theme. Below are the dates, presentations, and themes for each meeting:

Tribal Consultation Policy

CARB released its draft Tribal Consultation Policy in 2018 to guide CARB in its daily operations to work with tribes in a knowledgeable, sensitive, and respectful manner. The Tribal Consultation Policy details how CARB will continue to work to improve and strengthen its relationships with tribal governments and communities.

What's New

2020 San Diego Ozone State Implementation Plan

The California Air Resources Board will consider the San Diego County Air Quality Management Plan for attaining the Federal 8-hour 75 parts per billion (ppb) and 70 ppb Ozone standards at a public hearing to be held on November 19, 2020. The plan projects attainment for the standards by 2026 and 2032, respectively. Visit the 2020 San Diego Ozone State Implementation Plan for more information and documentation.

Local Air Districts

Tribes may interact with California's 35 local air districts, which are responsible for promulgating rules and regulations for stationary sources in the local areas. CARB interacts with air districts through support and oversight. The below links provide information on district rules, district maps, a directory of key personnel at each district, and the District Rules Log Database showing district rulemaking activity:

State Implementation Plans

Federal clean air laws require areas with unhealthy levels of ozone, inhalable particulate matter, carbon monoxide, nitrogen dioxide, and sulfur dioxide to develop plans, known as State Implementation Plans (SIPs). SIPs are comprehensive plans that describe how an area will attain national ambient air quality standards (NAAQS). The 1990 amendment to the federal Clean Air Act set deadlines for attainment based on the severity of an area's air pollution problem.

SIPs are not single documents. They are a compilation of new and previously submitted plans, programs (such as monitoring, modeling, permitting, etc.), district rules, state regulations and federal controls. Many of California's SIPs rely on the same core set of control strategies, including emission standards for cars and heavy trucks, fuel regulations and limits on emissions from consumer products. State law makes CARB the lead agency for all purposes related to the SIP. Local air districts and other agencies prepare SIP elements and submit them to CARB for review and approval. CARB forwards SIP revisions to the U.S. Environmental Protection Agency (U.S. EPA) for approval and publication in the Federal Register. The Code of Federal Regulations Title 40, Chapter I, Part 52, Subpart F, Section 52.220 lists all of the items which are included in the California SIP. At any one time, several California submittals are pending U.S. EPA approval.

Each SIP goes before the Board at different times. The most current Board meeting schedule, agenda, and a link for submitting comments can be found here.

Supplemental Environmental Projects

Do you have a project idea to help clean the air in your community?  If so, you can apply for project funding through California Air Resources Board’s (CARB) settlement of enforcement cases. This funding comes from a program called the Supplemental Environmental Projects (SEP) Program.  Nonprofit organizations, tribal governments, local agencies, governments, businesses, and more can apply to be funded through this program. The program’s goal is to improve public health, reduce pollution, increase environmental compliance, and raise public awareness through education.

Sometimes when regulated industries break air pollution control rules in California, they get a chance to directly help clean the air in local communities by funding SEP projects. Projects need to fall into certain categories, such as pollution prevention or reduction, environmental restoration and protection, environmental education and compliance training, community monitoring, and transboundary projects (which are projects that provide a direct benefit to Californians in and around California’s border).

Through the SEP program, funds have been committed to over 30 SEP projects worth over 11 million dollars between 2017 and 2019 in communities across California, and is hoping to fund many more in the coming years. 

There are no deadlines for submitting your proposal, so apply today, tomorrow, or any day you brainstorm a great idea to educate your community and help make your community’s air a little cleaner! 

If you are interested in learning more about the SEP program or if you have any questions you may contact us at

Funding Opportunities

The programs listed below have hundreds of millions of dollars available over the next several years to reduce air pollution across the State. Tribes may apply for funds from these programs to reduce air pollution on tribal lands. While CARB oversees these funding programs overall, some of these programs (such as the Carl Moyer Program) are implemented in partnership with local air districts.

Sustainable Transportation Equity Project

California Climate Investments is a statewide initiative that puts billions of Cap-and-Trade dollars to work reducing greenhouse gas emissions, strengthening the economy, and improving public health and the environment — particularly in disadvantaged communities. Tribal governments can receive funds to help fight climate change while addressing community needs for clean transportation, clean air, land conservation, agricultural equipment, and more. Visit our new webpage  to easily find California Climate Investments Programs that Tribal Governments are eligible to receive funding from. To learn more about funding opportunities and to hear about helpful resources and project success stories, visit our webinar announcement webpage.  Stay up to date on future planned webinars, including an upcoming webinar focused on funding opportunities for tribal governments.


Cap-and-Trade Compliance Offset Program and Tribes

CARB’s Cap-and-Trade Regulation is a set of rules that establishes a limit on greenhouse gas (GHG) emissions from the state’s biggest sources of GHGs. Tribes can voluntarily participate in the Cap-and-Trade program to generate offset credits, which can then be sold on the market.  Tribes participate in Cap-and-Trade through the Compliance Offset Program by submitting a forest offset project.  Because of their unique status as sovereign nations, to participate in the program, tribes must include a limited waiver of sovereign immunity that is legally binding under the tribe’s laws before any offset project located on tribal land can be listed.  More information can be found at:
