Green Zones Program – Environmental Justice Screening Method (EJSM)

The Environmental Justice Screening Method (EJSM) was developed to support the Green Zones Program in partnership with the University of Southern California, Program for Environmental and Regional Equity and Occidental College. EJSM illustrates cumulative risks associated with environmental justice within Los Angeles County by identifying areas that are disproportionately burdened by and vulnerable to multiple types of pollution and health risks. While it is similar to CalEnviroscreen developed by California Environment Protection Agency, EJSM was designed to provide flexibility and meet the County’s needs by incorporating detailed local data.
