CalEnviroScreen

Developed by the Office of Environmental Health Hazard Assessment (OEHHA) at the request of CalEPA, CalEnviroScreen is a science-based tool that identifies the California communities most burdened by pollution from multiple sources and most vulnerable to its effects. The tool will be used to help implement a state law (SB 535) that requires that 25 percent of the proceeds from the state’s cap-and-trade auctions be invested in projects that benefit disadvantaged communities, including 10 percent for projects located within these areas.

Overall CalEnviroScreen scores are calculated from the scores for two groups of indicators: Pollution Burden and Population Characteristics.

The tool uses data on 12 types of pollution and environmental factors and seven population characteristics and socioeconomic factors to create scores for each of the state’s 8,000 census tracts.

Overall CalEnviroScreen scores are calculated from the scores for two groups of indicators: Pollution Burden and Population Characteristics.
