Program
Carbon Mapper is a nonprofit based in Pasadena, California, with the mission to drive greenhouse gas emissions reductions by making methane and carbon dioxide data accessible and actionable. It focuses on filling gaps in the emerging ecosystem of methane and CO2monitoring systems by delivering data at facility scale that is precise, timely, and accessible to empower decision making and direct mitigation action. The organization leads a public-private coalition that is developing and deploying a constellation of satellites capable of detecting, quantifying, and verifying methane emissions worldwide. Data from these satellites will offer the next major step in scaling up the organization's robust data portal featuring thousands of direct observations of global methane and CO2 super-emitters.

The organization over time
Each line starts at 100 in 2021, so what you read is the shape rather than the size: 150 means half as much again as 2021, 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 2024 to 2025, from $17M to $45M (+165%).
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: 2024 3% · 2025 19%. Grants only. Government contracts and fees sit inside program revenue.
74% of Carbon Mapper Inc’s revenue is contributions — about as donation-reliant as the typical peer (87% for the typical peer).
Surplus & reserves
Operating surplus or deficit each year, and months of liquidity in hand. 3 of the last 5 reported years ran a deficit.

Who funds it, year by year
2020 → 2023: the base broadened from 1 funder to 5 funders, grant income rose $1.0M → $6.5M.
6 of 14 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 Carbon Mapper Inc’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
Carbon Mapper Inc leans on a few funders — its largest provides 39% of grant income and the top three 71%; half comes from just 2 funders.
the vertical line marks half of all grant income — 2 funders to its left
68% 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 Carbon Mapper Inc.
Largest funder’s share by year: 2020 100% · 2021 44% · 2022 50% · 2023 66% — 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
44% of Carbon Mapper Inc's funders are still giving 2 years after their first grant; 50% 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 Carbon Mapper 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 $40M that is directly attributable, 100% of it comes from funders outside California, across 4 states.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $50M arriving through sponsors registered in 4 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.
