原住民環境網(IEN)於一九九零年在美國成立，由基層原住民和個人組成，以解決環境和經濟正義問題。原住民環境網的活動包括擴建原住民社區與部落政府，發展機制以保護其人民與萬物所擁有的聖地、土地、水、空氣、天然資源和健康，同時建設經濟可持續發展的社區。原住民環境網還為了環境和經濟正義問題而召開全國性、區域性或地方性的會議，並且提供資源與援助，給以整個北美為主的相關原住民社區與青年，近年來還跨及全球。

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 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.
