About the Sierra Club Foundation

Founded in 1960, the Sierra Club Foundation is a 501(c)(3) tax-exempt public charity governed by an independent board of directors.

We work with individual and institutional donors to maximize financial support for strategic campaigns, provide flexible funding for innovation, help build capacity in the environmental movement, and create partnerships with a broad spectrum of allied organizations that further our shared environmental goals.

The Sierra Club Foundation is the independent fiscal sponsor of the charitable programs of the Sierra Club, a 501(c)(4) social welfare organization. We provide charitable grants to it and other nonprofit organizations to support scientific, educational, literary, organizing, advocacy, and legal programs that further our goals.
