Sierra Club Foundation: $89.1M Revenue, $88.5M Program Expenses

Sierra Club Foundation grades a B on the nonprofit efficiency rubric. 76/100 on the composite — above the national median, with strong performance on some factors balanced by middling performance on others.

Sierra Club Foundation reported $89.1M in 2023 revenue — a mid-sized nonprofit by U.S. standards. Organizations in this bracket typically operate with a small permanent staff, project-based program structures, and modest reserves. Sierra Club Foundation directs 80% of its expenses to programs — above the third-party-rater threshold for an efficient organization.

Revenue has declined meaningfully over the five-year filing window — a pattern that warrants attention to underlying funding sustainability. Sierra Club Foundation's 2023 revenue is materially below its earlier filings. CEO compensation is reported as zero in the filing — typical for nonprofits where the chief executive is paid through a related entity (parent system, university, or foundation) rather than the filing organization itself, or for small organizations whose chief is a volunteer or board member. Sierra Club Foundation works in Environment & Animals — environmental, conservation, animal-welfare, and natural-resources programs. The sector spans large international conservation groups and small local land trusts; the financial profile varies accordingly.
