The mission and goals of the Blackfeet Environmental Office are to "Protect, preserve and enhance the environment of the Blackfeet Reservation and carry out environmental stewardship through development and implementation of environmental policies and regulations.
These policies and regulations are to protect the health and welfare of the Blackfeet Nation's people and the natural and ecological resources."
On March 1, 1993, the Blackfeet Tribal Business Council, by resolution, officially recognized the Blackfeet Environmental Office as a Tribal Department.
