EPA Environmental Justice (EJ) Screen

EJScreen is an environmental justice mapping and screening tool developed by the Environmental Protection Agency (EPA) that provides nationally consistent demographic and environmental information for a project area. This screening tool combines environmental and demographic socioeconomic indicators into EJ Indexes. EJScreen users choose a geographic area; the tool then provides demographic socioeconomic and environmental information for that area. All of the EJScreen indicators are publicly available data. The tool provides a number of capabilities including color-coded mapping, the ability to generate a standard report for a selected area, and comparisons showing how a selected area compares to the state or the nation. For more information, please visit the EPA’s EJScreen webpage.

Climate and Economic Justice Screening Tool (Justice40 Initiative)

The current version of the tool provides socioeconomic, environmental, and climate information to inform decisions that may affect these communities. The tool identifies disadvantaged communities through publicly-available, nationally-consistent datasets.
