After presenting the Haudenosaunee philosophy at the United Nations Earth Summit in Brazil in 1992, the Grand Council created the Haudenosaunee Environmental Task Force to address environmental problems faced by Haudenosaunee communities. In 1993–1994, HETF delegates crafted the Haudenosaunee Environmental Restoration Strategy, which they presented to the United Nations at the Summit of the Elders in 1995 and to the Environmental Protection Agency (EPA). Since 1995, HETF has focused on building an organizational infrastructure and implementing the Restoration plan. In 2000, the EPA presented HETF with an Environmental Quality Award for its outstanding work. In 2002, HETF developed and hosted five workshops that were held at the Onondaga Nation. Onondaga is located at the center of Haudenosaunee territory physically and spiritually, which made holding the conferences there ideal. The workshops were designed to gather people of the Good Mind together to work toward a common understanding of the principles that could be used to create a culturally based environmental protection model. In 2002, HETF met with representatives from thirty seven federal agencies during a meeting titled “Polishing the Silver Covenant Chain.” The purpose of the meeting was to remind the participants of historic commitments to work together, in a partnership of mutual respect, to protect the environment and each nation’s sovereignty.
