How to use the Maryland Environmental Justice Screen (MD EJSCREEN) Tool

The Maryland Environmental Justice Screen Tool was developed to allow users to explore layers of environmental justice concern, determine the overall ‘EJ Score’ for census tracts in the state, and view additional context layers relevant to their area of concern or story they would like to tell. The tool is now operational on the ArcGIS online platform, where anyone can access either the Prince George’s County or Baltimore City oriented editions of the tool.

We developed the tool alongside fellow MIAEH professor Dr. Devon Payne-Sturges and our partners at the National Center for Smart Growth and the Maryland Environmental Health Network. Vetting and improvement of the tool in Bladensburg, MD and other Port Towns communities was facilitated by our community partner Port Towns Environmental Action. Additionally the tool has been presented to the Environmental Justice Legislative Team, the Maryland Commission on Environmental Justice and Sustainable Communities (CEJSC), and the Green Funders’ Network.


The tool’s development has been funded by the Town Creek Foundation (via the Maryland Commission on Climate Change) and the Maryland Department of Natural Resources (via NOAA, US Dept. of Commercel; Grant/NA17NOS4190153). Future improvements will include:

  • sub-layers for park equity, coastal resilience, and food scoring, and

  • platform improvements to reduce loading and rendering times.
