The Sierra Club Foundation promotes efforts to educate and empower people to protect and improve the natural and human environment.

  • Solve the climate crisis primarily through a successful transition to a resource-efficient, clean energy economy that better serves people and nature;

  • Secure protections for public lands and waters, promote healthy ecosystems and communities, and fight for clean air and water;

  • Expand opportunities for more people to explore, enjoy, and protect the planet by supporting programs and policies that reach across economic, cultural, and community lines to get people outdoors; and

  • Build a diverse, inclusive environmental movement that reflects and represents today’s American public, and prioritizes important connections between environmental health and social justice.


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.

  • We achieve our shared vision of a healthy planet through collaboration with the Sierra Club, our donors, and stakeholders.

  • We embrace integrity, through ethics, excellence, and transparency, to ensure the trust of our donors and partners.

  • We demonstrate stewardship in all we do through careful development and management of resources and responsible oversight of sponsored programs.
