The Interagency Working Group on Environmental Justice (EJ IWG) facilitates the active involvement of all Federal agencies to implement Executive Order 12898, "Federal Actions to Address Environmental Justice in Minority Populations and Low-Income Populations." The order states that "Federal agencies must identify and address, as appropriate, disproportionately high and adverse human health or environmental effects of their programs, policies, and activities on minority populations and low-income populations."

Established through the Order, the EJ IWG provides a forum for Federal agencies to collectively advance environmental justice principles. The EJ IWG works as a federal family to increase local community capacity to promote and implement innovative and comprehensive solutions to environmental justice issues.
