California Climate Investments reach diverse communities across the state. Ensuring projects benefit priority populations helps funding reach people most affected by pollution or with fewer resources to respond to climate change.

Some Californians live in areas exposed to multiple sources of pollution, and some communities have fewer resources to invest in low-carbon practices, transportation, or climate resilience. Communities facing these challenges can be hit hardest by climate change. Recognizing this, the Legislature requires that at least 35% of California Climate Investments benefit priority populations. Across the state, California Climate Investments benefit a broad range of communities in many ways, from more transportation options and lower energy costs to new job opportunities and more climate resilient communities.

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 2026, CalEPA released an updated designation and currently defines disadvantaged communities as:

  • The census tracts with the highest 25% of overall scores in the state based on CalEnviroScreen 5.0;

  • Census tracts lacking overall scores in CalEnviroScreen 5.0 due to data gaps but receiving the highest 5% of scores on a composite score measuring cumulative pollution burden;

  • Census tracts that overlap at least 25% with a 2022 disadvantaged community-designated census tract based on CalEnviroScreen 4.0; and

  • Lands under the control of federally recognized tribes, with updated tribal boundaries data.

Low-Income communities and households

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. Low-income communities are identified based on the income of an area, while low-income households are priority populations regardless of location. Together, these categories help California Climate Investments reach and benefit low-income Californians across the state.

Agencies administering California Climate Investment programs use the map and benefit assessment tools to determine if a project provides a benefit to a priority population. Other requirements for agencies that administer California Climate Investments are outlined in the Funding Guidelines. 


How California Climate Investments Benefit Priority Populations

As of October 2025, 76%, or $11.4 billion+, of implemented California Climate Investments project funding is benefiting priority populations, greatly exceeding statutory requirements. These investments are providing a variety of benefits including cleaner air, increased mobility options, greener communities, expanded access to clean energy, and new employment opportunities.

For detailed information about the share of funds benefiting priority populations under Senate Bill 535 and Assembly Bill 1550, view the Annual Report.

High‑Speed Rail expenditures are not included in these calculations. The Economic Investment - California High-Speed Rail highlights how cumulative funds implemented by the California High-Speed Rail Authority occurred in designated disadvantaged communities throughout California, spurring economic activity in these areas.
