Programs
Healthy Communities: Stopping harmful pollution in all communities is one of the Councils impact areas in its 2024-2030 Strategic Plan. This year, Clean Air Council held existing and proposed polluting facilities accountable for their pollution. Among other things, the Council petitioned US EPA to reject Pittsburgh-area Edgar Thomson steel mills inadequate air permit and to replace it with a stronger one; successfully pushed for US EPA to pass stronger air quality standards for coke-making facilities to protect communities; supported residents to convince the City of Philadelphia to take enforcement action against illegal auto-repair operations in Southwest Philadelphia; held four events in Philadelphia greenspaces and trails that attracted over 1,000 people; and guided the Philadelphia Technicians Institute to make their campus smoke-free.

This year, the Council worked to prevent proposals for harmful petrochemical facilities from advancing. This work was best exemplified when earlier in 2024 the Council organized impacted communities to successfully prevent the building of Encinas toxic plastics recycling facility in Northumberland County. The Council continued the past year to monitor and organize around similar proposed facilities. The Council also sought the reduction of single-use plastic bags and over the years has supported Pennsylvania municipalities in passing ordinances to limit the use of such bags.

This year, the Council worked to ensure public transit is convenient, safe, and well-funded. It participated in a coalition to ensure Southeastern Pennsylvania Transportation Authority (SEPTA) was adequately funded and to prevent cancelled transit services and fare hikes as a result. The Council worked to ensure biking and walking is safe and enjoyable. As in prior years, it organized Love to Ride cycling challenges resulting in over 80,000 miles biked and ran Feet First Philly to make neighborhoods better and safer for walking.

So is achieving greater renewable energy in Pennsylvania as the flip side of the same objective of cleaning energy usage in the Commonwealth. This year the Council mobilized grassroots opposition to gas infrastructure and promoted no-drill zones near communities. It petitioned the Pennsylvania Department of Environmental Protection to establish mandatory setbacks between wells and homes, schools, hospitals and drinking water wells. The Council also secured ambitious local renewable energy policies that will lead to new renewable energy projects in Pennsylvania. Because of the Councils efforts, three counties adopted solar laws that could result in over 1,000 megawatts of electricity-generating solar projects.

The organization over time
Each line starts at 100 in 2020, so what you read is the shape rather than the size: 150 means half as much again as 2020, 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 $2.8M to $4.6M (+64%).
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 13% · 2021 6% · 2022 17% · 2023 5% · 2024 13% · 2025 14%. Grants only. Government contracts and fees sit inside program revenue.
98% of Clean Air Council’s revenue is contributions — more reliant on donations than three-quarters of its peers (88% for the typical peer).
Surplus & reserves
Operating surplus or deficit each year, and months of liquidity in hand. 3 of the last 6 reported years ran a deficit.

Who funds it, year by year
2017 → 2023: the base broadened from 13 funders to 23 funders, grant income rose $777k → $2.8M.
12 of 53 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 7% 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 Clean Air Council’s funders (the co-funder graph). Top 30 of 53 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
Clean Air Council has a broad base — no single funder exceeds 26% of grant income, and it takes 3 funders to reach half.
the vertical line marks half of all grant income — 3 funders to its left
54% 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 Clean Air Council.
Largest funder’s share by year: 2017 26% · 2018 43% · 2019 45% · 2020 38% · 2021 34% · 2022 32% · 2023 36% — growing more concentrated.
“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
40% of Clean Air Council's funders are still giving 3 years after their first grant; 49% 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
Clean Air Council draws 56% of its grant income from funders outside Pennsylvania, across 11 states in all.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $979k arriving through sponsors registered in 8 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.
