The mission of the Blackfeet Environmental Office is 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.”
The goal of these policies and regulations is to protect the health and welfare of the Blackfeet Nation's people and its 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.
