Mission: The Sierra Club Foundation promotes climate solutions, conservation, and movement building through a powerful combination of strategic philanthropy and grassroots advocacy. We partner with individual and institutional donors to align financial resources with strategic outcomes, provide flexible funding for innovation, build capacity in the environmental movement, and create partnerships with a broad spectrum of allied organizations around shared values and goals. As the fiscal sponsor of the charitable programs of the Sierra Club, we provide resources to it and other nonprofit organizations to support scientific, educational, literary, organizing, advocacy, and legal programs that further our goals. (Less)
