We conduct a scan of national, state, and local environmental justice data tools and develop a framework to compare the tools across a number of dimensions. These include the development process, the indicators and data sources used in each tool, if and how race and ethnicity were included, and how tools quantified burdens for and prioritized among potential environmental justice communities. We present these dimensions in an accompanying Airtable for each of the 31 tools that we scanned. Using this analytical framework, we identify five key themes that emerge from our comparative analysis and offer recommendations for how screening tools can be improved to promote data-driven decision making that advances environmental justice. Our work adds to an existing—and growing—body of literature on the uses and limitations of national, state, and local environmental justice data tools.
