The Tribal workgroup identifies and highlights innovative projects that advance the health of tribal communities and their interconnections to the earth. Monthly conference calls and a wealth of resources at TribalP2.org help to address environmental issues through pollution prevention methodologies, and share best practices. The Workgroup consists of tribal entities, local, state, and federal agencies, academia, and not-for-profit organizations whose mission is to work collaboratively with tribes throughout the United States. The workgroup was formed in 2003 from a U.S. EPA grant issued as a result of tribal requests for more specific tribal communication about pollution prevention efforts directly relating to tribes.
