Some Californians live in areas that are exposed to multiple sources of pollution and some communities don’t have enough resources to invest in low-carbon practices, transportation, or climate resilience. These communities will be the first impacted and the hardest hit by the effects of climate change. Recognizing this, the Legislature requires that at least 35% of all California Climate Investments benefit priority populations.
How Priority Populations are Defined
Per Senate Bill 535 and Assembly Bill 1550, 35% California Climate Investments must be allocated to disadvantaged Communities, low-income communities and low-Income households, collectively referred to as priority populations. These communities are defined as follows:
Disadvantaged communities: The California Environmental Protection Agency (CalEPA) is responsible for identifying disadvantaged communities. In 2022, CalEPA released an updated designation of disadvantaged communities and currently defines disadvantaged communities as:
The top 25% of census tracts experiencing disproportionate amounts of pollution, environmental degradation, and socioeconomic and public health conditions according to the Office of Environmental Health Hazard Assessment’s CalEnviroScreen 4.0 tool.
Census tracts lacking overall scores in CalEnviroScreen 4.0 due to data gaps but receiving the highest 5% of CalEnviroScreen 4.0 Pollution Burden composite scores;
Census tracts identified in 2017 as disadvantaged, regardless of their scores in CalEnviroScreen 4.0; and
Lands under the control of federally recognized Tribes.
Low-Income communities and households are those with incomes either at or below 80% of the statewide median or below a threshold designated as low-income by the Department of Housing and Community Development.

Using funds awarded by the Clean Mobility Options program, the Big Pine Paiute Tribe of the Owens Valley, a federally recognized California Native American Tribe, conducted a community-driven transportation needs assessment to determine the transportation needs and preferences of Big Pine Paiute’s residents. After the needs assessment is completed and approved by their Tribal Council, the Big Pine Paiute Tribe can use it to apply for additional funding from Clean Mobility Options or other transportation grant programs to implement clean mobility projects.
Supported in part by nearly $23 million award from the Affordable Housing and Sustainable Communities Program, Resources for Community Development (RCD) will provide 87 affordable rental homes in the city of Berkeley through the Maudelle Miller Shirek Community project. In addition to large, family-sized apartments and permanent supportive housing for formerly homeless residents, the ground floor of the building will become the headquarters of Healthy Black Families, Inc., a South Berkeley-based nonprofit dedicated to the health of Black families in the community. This project will help Black families and formerly homeless individuals live healthier lives and receive health services through on-site programs and services offered by Healthy Black Families, Inc.,, RCD’s resident services, and the City of Berkeley Mental Health department and third-party service providers.
The California Alliance for Community Composting (Alliance)is helping community groups develop or expand 50 community composting sites in disadvantaged and low-income communities across California using funds from the Community Composting for Green Spaces Grant Program. Altogether, these sites are expected to prevent nearly 11,000 tons of organic waste from going to landfills by creating compost, which prevents the release of greenhouse gases during its decomposition. The Alliance’s work will also provide communities with additional benefits, including free compost, job training, and more.
Funded in part by a nearly $1,000,000 grant from California Department of Forestry and Fire Protection’s Urban and Community Forestry Program, the Conservation Corps of Long Beach (CCLB) is implementing an urban wood recovery apprenticeship program that has the potential to be a model for other programs across California. This program is teaching Corpsmembers how to remove hazardous trees throughout the city, control insects and diseases, and divert woody biomass from landfills to help keep greenhouse gases sequestered in the wood. Additionally, trees will be replaced to mitigate poor air quality, a lack of urban green space, and improve storm water retention in disadvantaged communities. Ultimately, this program will provide a foundation for Corpsmembers interested pursuing jobs in urban forestry.
Thanks to $50,000 from the California Air Resources Board’s Fluorinated Gas Reduction Incentive Program, Stater Bros. Markets installed a climate-friendly refrigeration system at a new supermarket in Whittier that will result in a reduction of greenhouse gas emissions that is the equivalent to taking more than 1,000 vehicles off the road for one year. Since refrigerants are among the fastest growing climate pollutants worldwide it is important to have projects like this one to demonstrate that transitioning the grocery sector toward cleaner refrigerants is an effective strategy for mitigating climate change.
The San Joaquin Valley Transit Electrification Project has deployed 15 zero-emission battery electric transit buses, and 15 charging stations, in disadvantaged communities throughout the San Joaquin Valley.
In May 2017, the Sacramento Metropolitan Air Quality Management District (AQMD) and its partners unveiled the first six of 29 electric school buses — what will be the largest electric school bus deployment in the U.S. — at a press event in north Sacramento.
The adjacent ports of Long Beach and Los Angeles combined are the largest fixed sources of air pollution in the South Coast Air Basin, one of the most polluted air basins in the United States, in large part because the trucks and equipment used at the ports burn diesel fuel. Recognizing this, the Sustainable Terminals Accelerating Regional Transformation demonstration project was awarded $50 million to replace trucks and equipment with zero‑emission technology. The funding, which comes from California Climate Investments, supports the deployment of 102 pieces of zero‑emission terminal equipment and trucks at seaports across California, including at the ports of Los Angeles and Long Beach. These funds are also supporting the development of new, cleaner tugboats; the deployment of two container vessels with cleaner‑burning engines; and advanced workforce development programs to support sustainable goods movement across California.
This program will deploy 38 electric yard trucks, 9 electric gantry cranes, 18 electric heavy lift forklifts, and 15 zero-emission Class 8 trucks. The program is also including a workforce development component with curriculum being developed to support the deployment of this technology with local school districts near the three port locations, community colleges and Long Beach State University.
