Established in 1990 within the United States, IEN was formed by grassroots Indigenous peoples and individuals to address environmental and economic justice issues (EJ). IEN’s activities include building the capacity of Indigenous communities and tribal governments to develop mechanisms to protect our sacred sites, land, water, air, natural resources, health of both our people and all living things, and to build economically sustainable communities.IEN accomplishes this by maintaining an informational clearinghouse, organizing campaigns, direct actions and public awareness, building the capacity of community and tribes to address EJ issues, development of initiatives to impact policy, and building alliances among Indigenous communities, tribes, inter-tribal and Indigenous organizations, people-of-color/ethnic organizations, faith-based and women groups, youth, labor, environmental organizations and others. IEN convenes local, regional and national meetings on environmental and economic justice issues, and provides support, resources and referral to Indigenous communities and youth throughout primarily North America – and in recent years – globally.

Indigenous Environmental Network（IEN）於1990年在美國境內由一般原住民民眾為倡導環境與經濟正義而成立，IEN的行動包含促使原住民社群和民族政府發展保護聖域、土地、水源、空氣、自然資源與物種健康的機制，並建立經濟永續的社群。為達成這些目標，IEN的方法為成立資訊交流中心、組織訴求活動、引導公眾行為與意識、協助社群或部落提倡環境與經濟正義和發展提案以影響政策制定，另外還與原住民社群、部落、部落結盟或原住民組織、弱勢民族組織、信仰與女性團體、青年、勞工、環境團體等等進行結盟。IEN召開地方、區域性和國家型聚會討論環境和經濟正義議題，並提供以北美洲為主的原住民社群與青年支持、資源和專業人士指引給，近年來則會將這項幫助推行至全球。
