Sierra Club Foundation: $89.1M Revenue, $113.5M Expenses

Sierra Club Foundation earns a C on the efficiency rubric — the median bucket on the NonprofitTruth scale, indicating performance close to the national midpoint across financial reserves, officer compensation, and revenue consistency. Composite score: 58/100.

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 holds a moderate reserve position relative to its $113.5M in annual expenses — neither fragile nor a large surplus.

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. Officer compensation is modest relative to organizational size: Sierra Club Foundation reports $1.4M in total compensation for current officers and key employees (Form 990 Part IX, line 5) against $89.1M in revenue. The ratio is well within the bands third-party charity raters consider reasonable at this scale. 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.
