Carbon credits aren't paid for the carbon your soil already holds — they're paid for the additional carbon you sequester over time, measured against a baseline. This tool builds that record: set a baseline for each field, log new soil tests as they come in, and watch your carbon stock grow alongside the practices that drive it.
Want a one-off estimate instead? Use the quick calculator.
Add each field, paddock, or block you want to track. You can use different soil test results, depths, and targets for each one.
No fields yet — add your first field above to open its carbon record, or load the sample data to see how the tracker works.
Enter the numbers from each new soil test. Lab results carry far more weight with carbon programs than estimates, so record the lab reference when you have one.

Carbon programs pay for sequestration driven by new practices. Logging when each practice started is the evidence you'll need.
Credits are issued per tonne of CO₂e of additional, verified sequestration. Set a price to see what your gains so far would be worth, and what your current rate could earn each year.
Indicative only. Real credits must be issued through a registered program (for example a Verra or Climate Action Reserve soil methodology) and require accredited baseline sampling, a documented practice change, third-party verification, and a permanence commitment. This tracker builds the record those programs ask for — it does not issue credits.
Each measurement is converted to a carbon stock using the standard soil science equation:
Soil carbon builds slowly — well-managed fields typically gain on the order of 0.2–1 t CO₂e per acre per year, which shows up as just a few hundredths of a percent SOC change. That's why consistent sampling (same depth, same season, same lab) matters so much: it keeps your trend believable.
