What Clean Air Task Force Inc does
Mission
Push the technology and policy changes needed to achieve a zero-emissions, high-energy planet at an affordable cost.
As stated on its FY2024 Form 990.
Programs
On its FY2023 return the organization reported starting a significant new program.
Clean energy infrastructure: transitioning to a global zero-carbon energy system requires us to address the limitations of our current infrastructure. Our current system is not equipped to meet the demand for increased capacity. We need to look at new kinds of power generation (both renewable and thermal), bigger volumes of electric power transmission, pipelines to move co2 and hydrogen, and storage for the carbon dioxide that is extracted from industrial processes. At catf, we work in concert with stakeholders and partners to tackle challenging questions and envision a path forward for the infrastructure we need to have 30 years from now and work with them to turn that vision into reality. Fusion energy: a new wave of investment into private enterprises is changing the landscape of fusion energy research and challenging the notion that it is purely a scientific endeavor. While numerous technological and commercial hurdles remain, the potential impact of the successful commercialization of fusion technology before 2050 would be substantial. Activities under this program look to understand the commercial viability, to facilitate effective public support, and to identify key policy, regulation, and market challenges or opportunities for commercial fusion efforts.
Its own explanation, from Schedule O of that return (Part III, line 2).
Methane pollution prevention international - catalyze deep, global reductions in methane emissions to reduce near-term warming and protect against the risk of irreversible changes to our climate. Catf advocates for super pollutant emissions reductions like methane around the world by supporting scientific research, promoting policy initiatives, encouraging the development of financial incentives for pollution controls, and championing and defending standards that can dramatically reduce emissions.
$5,293,426 spentof which $84,733 as grants$50,000 earned by the program13% of program spendingZero carbon fuels - catf has identified six sectors that are especially challenging to decarbonize, and for which zero-carbon fuels could be particularly advantageous: marine shipping, heavy-duty long-haul trucking, ironmaking, high-temperature industrial process heating, aviation, and long-duration energy storage. In addition, building heating in very cold climates may be especially difficult to fully electrify due to peak grid loads, and other sectors of transport like offroad vehicles may not be fully decarbonized through electrification by 2050. Catf is executing on its comprehensive, multi-faceted approach within each of these sectors with rigorous analysis, public policy design, public education and advocacy, identification of needed innovation initiatives, and promotion of demonstration projects such as hydrogen hubs.
$3,327,997 spent8% of program spendingCarbon capture - catfs work in carbon capture aims to achieve global net-zero emissions by midcentury. Catf works towards this goal by developing and advocating for policies aimed at making carbon capture, removal, and storage technologies cost competitive with using unabated fossil fuels for power generation and for use in the industrial sector, globally. Our goal is to rapidly accelerate the adoption of carbon capture technologies to prevent the emission of millions of tonnes of co? From power generation and industrial sources around the world.

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 2020 to 2021, from $20M to $32M (+62%).
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.
98% of CLEAN AIR TASK FORCE INC’s revenue is contributions — more reliant on donations than three-quarters of its peers (87% for the typical peer).
Surplus & reserves
Operating surplus or deficit each year, and months of liquidity in hand. 2 of the last 8 reported years ran a deficit.

Leadership and staff
The officers, directors, trustees and key employees listed on each return. Joined and no longer listed compare each filing with the year before, matching people by surname and first initial; a year after a gap, or a roster under three people, has no comparison.
Who funds it, year by year
2017 → 2023: the base broadened from 12 funders to 214 funders, grant income rose $3.1M → $26M.
64 of 482 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 54% 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 TASK FORCE INC’s funders (the co-funder graph). Top 30 of 482 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 TASK FORCE INC has a broad base — no single funder exceeds 18% of grant income, and it takes 7 funders to reach half.
the vertical line marks half of all grant income — 7 funders to its left
67% 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 TASK FORCE INC.
Largest funder’s share by year: 2017 24% · 2018 23% · 2019 21% · 2020 17% · 2021 17% · 2022 24% · 2023 20% — 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 CLEAN AIR TASK FORCE INC's funders are still giving 3 years after their first grant; 51% 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
54% of CLEAN AIR TASK FORCE INC's grant income arrives through donor-advised or pass-through sponsors, whose addresses record where the money is held rather than where the donor is. Of the $60M that is directly attributable, 98% of it comes from funders outside Massachusetts, across 39 states.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $71M arriving through sponsors registered in 24 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.
