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 Tribal Activities Report for fiscal year 2020-2021 outlines CARB's work with Tribes. Below are a few select topic areas that may be of interest to tribes.

Register for August 31st Workshop

A workshop for tribal nations to discuss California’s Approach under EPA’s Climate Pollution Reduction Grant Program (CPRG Program) will be hosted by the California Air Resources Board on Thursday, August 31, 2023, from 9:00 to 11:00 AM. Please register for the workshop at this link:  Once you register, you will receive a Zoom link to join the workshop.

The CPRG Program was made possible by the Inflation Reduction Act  and is being administered by the U.S. Environmental Protection Agency (EPA). The program offers federal funding to support climate projects that either reduce greenhouse gas emissions or help sequester carbon. The program has two phases. In the first, states, large metropolitan areas, tribes, and territories across the U.S. were offered the opportunity to secure grants to create three climate plans over four years. These climate plans include a Priority Climate Action Plan (due in March 2024), a Comprehensive Climate Action Plan (due in mid-2025), and a Status Report (due in 2027). All the climate actions in any Priority Climate Action Plan can compete for $4.6 billion in federal funding. This competition is the second phase of the CPRG Program. 

Some tribal nations have worked to secure their own planning grants under the CPRG Program and will draft their own Priority Climate Action Plan. The State of California and nine metropolitan areas will as well. CARB serves as the lead agency for the State of California.

Even if a tribe does not have a planning grant, they can still work with the State to make sure their highest priority climate actions become eligible to compete for funding under the CPRG Program. It is important to the State to hear and include in our Priority Climate Action Plan any expertise, perspectives, and suggestions that tribal nations might want to share.  

On behalf of California, CARB will host a workshop dedicated to tribal nations about the State’s Priority Climate Action Plan. This workshop will offer information on the CPRG Program and the State’s plans under it. We will then use most of the time to answer questions and hear comments from tribal representatives. 

If you have any questions or concerns, please feel free to reach out to Tracey Harper, CARB’s Tribal Liaison, at

CARB is available for consultations with any tribal nations that wish to discuss the CPRG Program and how to coordinate under it to bring the greatest climate and local benefits to the State and to tribal nations. 

Apply for Funding

You are invited to apply for funding through Planning and Capacity Building (Planning), Clean Mobility in Schools (CMIS), and the Sustainable Transportation Equity Project (STEP).

Zero-Emission Truck Regulation—Advanced Clean Fleets—Opportunity to Share Your Thoughts

The California Air Resources Board (CARB or Board) continues its work cutting emissions from polluting trucks, especially those that run through neighborhoods. At its October 27, 2022 public hearing, the Board considered staff’s proposed Advanced Clean Fleets regulation, which would accelerate the widespread addition of zero-emission vehicles, including medium- and heavy-duty vehicles and light-duty package delivery vehicles. CARB invites everyone interested in the proposed Advanced Clean Fleets regulation to read and comment on the latest proposed changes—which are available on the Regulatory Documents page under the “Hearing Action and Supplemental 15 Day Notices” section. The comment period ends on April 7 and the Board will consider final approval of this proposal at its public hearing on April 27-28, 2023.The proposed regulation would require certain fleets to add zero-emission vehicles starting in 2024 and would set a date for an end to the sale of medium- and heavy-duty internal combustion engine vehicles in California, like those that run on diesel or gasoline. 

At the October public hearing, the Board directed CARB’s Executive Officer to consider and seek public comment on any other needed changes to the proposed regulation. Staff will respond in writing to comments received during the formal comment period.

Zero-emission vehicles include battery-electric and fuel cell electric vehicles; these vehicles produce no tailpipe emissions, reduce brake wear, and, in general, have lower life cycle greenhouse gas emissions compared to diesel and other combustion fuels. In contrast, in 2021, medium- and heavy-duty diesel trucks contributed 72 percent of the state’s on-road vehicle oxides of nitrogen (NOx) emissions which are major contributors to smog-causing, ground-level ozone pollution in California, and 21 percent of statewide mobile source greenhouse gas emissions, while making up only 6 percent of all the vehicles on the road.

The proposed Advanced Clean Fleets regulation would help reduce air pollution emissions that pose acute health risks to the local communities where heavy-duty trucks and other vehicles commonly operate, and would help achieve CARB’s climate change emissions reduction goals.

The Board looks forward to hearing from all who are interested in the proposed Advanced Clean Fleets regulation. You can read more about this proposed regulation on the Advanced Clean Fleets program webpage, and you can find the latest changes to the proposal and a link to where you can comment on the regulatory documents webpage.  A summary of the newly proposed changes can be found in the 15-Day Notice. Also, check out the factsheets that summarize the regulation, and stay informed about upcoming events by subscribing to CARB’s ZEV Fleet GovDelivery email list. You can access the April 27-28, 2023, Board hearing by webcast or you can attend in person in Sacramento. Click here for more information about this or other Board hearings.

Final 2022 Scoping Plan

The 2022 Scoping Plan for Achieving Carbon Neutrality (2022 Scoping Plan) lays out a path to achieve targets for carbon neutrality and reduce anthropogenic greenhouse gas (GHG) emissions by 85 percent below 1990 levels no later than 2045, as directed by Assembly Bill 1279. The actions and outcomes in the plan will achieve: significant reductions in fossil fuel combustion by deploying clean technologies and fuels, further reductions in short-lived climate pollutants, support for sustainable development, increased action on natural and working lands to reduce emissions and sequester carbon, and the capture and storage of carbon.

The Final 2022 Scoping Plan and its appendices are available on CARB's website.

Draft Program Guidelines for the 2021-2022 Greenhouse Gas Reduction Fund (GGRF) Woodsmoke Reduction Program Available for Public Review and Comment

Residential wood smoke is an issue in many tribal communities.  As part of the California Climate Investments Woodsmoke Reduction Program, CARB will provide incentives for voluntary replacement of old wood-burning stoves with cleaner and more efficient home heating alternatives. The Program, administered by CARB, is implemented by the California Air Pollution Control Officers Association in coordination with local air pollution control districts or air quality management districts (Districts).  Not all Districts will elect to participate in the 2021-2022 round of funding, but households residing on tribal lands within the jurisdiction of participating Districts will qualify for incentives.  CARB is accepting comments on the Draft Guidelines for the 2021-2022 Woodsmoke Reduction Program through December 8, 2022. Comments can be submitted to the electronic docket or via email.

Fact Sheets

CARB’s Transportation and Toxics Division would like to share several fact sheets related to our recent and upcoming regulations. We are happy to make ourselves available to answer any questions you may have.

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:

Laws and Regulations

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

Funds can be used to purchase or lease new or used vehicles, bicycles, scooters, and other clean mobility options along with associated equipment, infrastructure, and operating costs to implement clean mobility services. CMO is administered by a team that provides comprehensive training, technical assistance, learning tools, and information-sharing opportunities to build the capacity of under-resourced organizations to enhance mobility access in their communities.

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:
