What Earthworks does
Mission
The Corporation is organized exclusively for charitable and educational purposes. Earthworks is dedicated to protecting communities and the environment from the impacts of irresponsible mineral and energy development while seeking sustainable solutions.
As stated on its FY2025 Form 990.
Programs
The Energy Program includes our work on oil, gas and petrochemicals. This program works to change federal, state, and local government policy and to support and empower communities impacted by existing and proposed energy extraction, to raise awareness about the impacts of unconventional oil and methane gas, and to reduce the impacts of all forms of energy extraction. This program was formerly known as Oil & Gas Accountability Project.

This program supports communities and protects special places by stopping mining where it doesn't belong, reins in the riskiest mining practices, and reforms and defends state, federal and international policies that protect communities, water, wildlife, oceans and other natural resources.

The organization over time
Each line starts at 100 in 2017, so what you read is the shape rather than the size: 150 means half as much again as 2017, 50 means half. The number beside each label in the key is where it ended. The shaded band is where the middle 50% of its peers' revenue would sit, given their growth.
Balance sheet
Total assets and total liabilities at each year end, in dollars. The largest one-year move in total assets was 2022 to 2023, from $6.6M to $10M (+56%).
How it's funded, over time
Each bar is one year's revenue split into where it came from, and every bar is the same height — these are shares, not amounts, so a year that raised twice as much looks the same size. Hover a bar for the split.
Government-grant reliance: 2020 6%. Grants only. Government contracts and fees sit inside program revenue.
98% of Earthworks’s revenue is contributions — more reliant on donations than three-quarters of its peers (30% for the typical peer).
Surplus & reserves
Operating surplus or deficit each year, and months of liquidity in hand. 1 of the last 9 reported years ran a deficit.

Who funds it, year by year
2017 → 2023: the base broadened from 29 funders to 55 funders, grant income rose $2.1M → $7.4M.
36 of 131 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 27% of grant dollars received. That money is really individual donors directing a sponsor; the institutions to cultivate are the non-DAF funders.
From the IRS filings of Earthworks’s funders (the co-funder graph). Top 30 of 131 funders by total. Association, not causation. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.
How concentrated its funding is
Earthworks has a broad base — no single funder exceeds 19% of grant income, and it takes 6 funders to reach half.
the vertical line marks half of all grant income — 6 funders to its left
46% of the income these shares are computed over arrives through pass-through sponsors or from payers whose filings do not say what kind of payment it is. Concentration is still measured over all of it, because the money is real; what it does not support is a claim about how many institutions have chosen to fund Earthworks.
Largest funder’s share by year: 2017 47% · 2018 46% · 2019 35% · 2020 14% · 2021 27% · 2022 22% · 2023 27% — diversifying over time.
“Effective funders” = inverse Herfindahl index (1 / Σ shareᵢ²) — the number of equal-sized funders that would give the same concentration. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.
How long its funders stay
45% of Earthworks's funders are still giving 3 years after their first grant; 53% give in more than one year at all.
Share of funders still giving k years after their first recorded grant, pooled across every acquisition cohort. A funder counts as retained in a year only if it made a grant that year. Measured to FY2023, the last fiscal year that has finished arriving — a funder cannot be counted as lapsed in a year most filers have not reached.
Where its funders are
Earthworks draws 91% of its grant income from funders outside Washington, D.C., across 23 states in all.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $9.1M arriving through sponsors registered in 15 states is excluded from the map and the split above: a sponsor holds money on a donor’s behalf, so its registered address would place those dollars somewhere no donor need ever have been. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.
Against its field
Earthworks runs a healthier operating margin than three-quarters of the 132 public benefit nonprofits its size.
