What CarbonPlan does
Mission
Improving the transparency and scientific integrity of climate solutions through open data and tools.
As stated on its FY2024 Form 990.
Programs
Research & Development Refers broadly to analysis in support of our strategic or exploratory objectives. Often involves deep-dive domain-specific investigation alongside cross-cutting analysis of projects and programs. Primary activities include writing code and documentation, organizing and analyzing data, visualizing information, engaging in external collaborations, and documenting research results.

Also includes the external-facing communication of all of our work. Primary activities include engaging with journalists, reviewing legal and regulatory materials, responding to public comment solicitations, and writing a variety of external-facing content.
$430,006 spent17% of program spending
The 2 programs described on its FY2025 Form 990, listed largest first by expense. Program spending in total: $2,481,823.
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 2020 to 2021, from $1.7M to $4.0M (+135%).
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: 2021 7% · 2022 19% · 2023 14% · 2024 6%. Grants only. Government contracts and fees sit inside program revenue.
92% of CarbonPlan’s revenue is contributions — more donation-reliant than the typical peer (88% for the typical peer).
Surplus & reserves
Operating surplus or deficit each year, and months of liquidity in hand. 0 of the last 5 reported years ran a deficit.

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
2020 → 2023: the base broadened from 6 funders to 11 funders, grant income rose $460k → $3.1M.
7 of 25 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 56% 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 CarbonPlan’s funders (the co-funder graph). 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
CarbonPlan leans on a few funders — its largest provides 29% of grant income and the top three 64%; half comes from just 2 funders.
the vertical line marks half of all grant income — 2 funders to its left
60% 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 CarbonPlan.
Largest funder’s share by year: 2020 54% · 2021 66% · 2022 31% · 2023 32% — 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
17% of CarbonPlan's funders are still giving 3 years after their first grant; 48% 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
56% of CarbonPlan'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 $5.1M that is directly attributable, 63% of it comes from California funders.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $6.6M arriving through sponsors registered in 6 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
CarbonPlan runs a healthier operating margin than half of the 2,186 environment nonprofits its size.

These figures are read directly from IRS Form 990 / 990-PF e-file XML: this organization’s own return for FY2024 (financials across 2020–2024), and the filings of 25 funders that report grants to it. “On record” means captured in the filings we have parsed — a funder that does not e-file, or whose grant detail is not itemized, will not appear. Filings run roughly 12–24 months behind. Trends on this page end at FY2023, the last fiscal year that has finished arriving; later years are shown and marked, and move no figure.
