LOS ANGELES — It's been 10 years since CalEPA created CalEnviroScreen, a data-driven mapping tool that highlights sources of pollution like traffic, ozone and pesticides across the state.

The tool is publicly available and has led policymakers to invest $6 billion in California Climate Investments across disadvantaged communities, according to CalEPA. It has also been used by organizations like Physicians for Social Responsibility Los Angeles to push for environmental justice.
