EJSCREEN: A New Environmental Justice Screening and Mapping Tool From the EPA

From the EPA Connect Blog:

Too often, America’s low-income and minority communities bear the brunt of our country’s pollution. These environmental and public health threats make it harder for kids with asthma to learn in school, and for people impacted from pollution to lead active and healthy lives.

There are many ways EPA is working to protect these overburdened communities. For the past two years, we’ve been using a screening and mapping tool called EJSCREEN to inform our work, whether its grant writing, policy decisions or enforcement.


EJSCREEN uses high resolution maps combined with demographic and environmental data to highlight places that may have higher environmental burdens and vulnerable populations. EJSCREEN can help you better understand the pollution burdens facing a community that has a high proximity to traffic, for instance, and also has a high proportion of people who are in poor health, have reduced access to care, lack resources or language skills, or are at susceptible life stages. This kind of data is essential for government agencies, non-profits, and any stakeholder working to make a positive impact in American communities affected by pollution.

EJSCREEN combines environmental and demographic information into “EJ indexes,” giving the user a way to measure impacts to better understand areas in need of environmental protection, health care access, housing, infrastructure improvement, community revitalization, and climate resilience.
