Today, Senator Edward J. Markey (D-Mass.), Senator Tammy Duckworth (D-IL) and Congresswoman Cori Bush (MO-01) announced the introduction of the Environmental Justice Mapping and Data Collection Act of 2021, legislation that would take ground-breaking steps toward identifying and connecting environmental justice communities with policy outcomes. This legislation, written through collaboration with grassroots environmental justice leaders, aims to create and authorize funding for a system to comprehensively identify the demographic factors, environmental burdens, socioeconomic conditions, and public health concerns that are related to environmental justice and collect high-quality data through community engagement and a government-wide interagency process. These data would be used to build layered maps depicting which communities experience environmental injustices, and would assist the Biden administration in directing at least 40 percent of the investment in a clean and climate-safe future into communities that have been harmed by racist and unjust environmental practices.
