Frequently asked questions
The measurement
We measure the soil organic carbon in your fields, once a year, and report the change against your own baseline. Real soil samples, laboratory analysis and satellite imagery, field by field, with the accuracy stated. The results are yours. Emissions reporting and carbon credits are separate tiers, added only when you ask for them.
Measured. We take physical soil samples on every farm we monitor and analyse them by dry combustion in an ISO-accredited laboratory. Nothing is estimated from a list of practices you say you follow, and nothing is inferred from a model of what a typical soil should do.
The samples anchor the result. Our AI then ties them to satellite imagery of the same fields at 100 readings a hectare, a value every 10 metres, so what you get is a map and an accurate field total rather than a list of sample points. The step-by-step method is in how soil carbon is measured.
A report, field by field, showing the change against your own baseline with the accuracy stated, and a map of each field at 10-metre resolution showing where carbon is being held or lost. Because we track soil carbon, management practice, yield and emissions across every project we monitor, we can also tell you what worked on farms like yours.
No. We measure what your management actually does to the soil in each climatic year. We tell you how your soil is reacting. You decide how to adapt.
Your SBI number, a short call to agree field boundaries and sampling access, about half a day on farm while the sampling is done, and the records you already keep. That is the whole commitment.
Accuracy and evidence
Some samples are held back and the AI never sees them. Its estimate at those points is compared with what the laboratory actually found, and that difference is the error of the method on your farm, on your soil, in that year. It is deducted in full before anything is reported. See how the accuracy is stated.
No sampling density a farm could afford gets close to 100 readings a hectare, and a sample-only result is precise at the sample points and blind everywhere else. The satellite reaches that density between the samples, and the held-back check is what keeps it honest.
Our method went through four rounds of independent scientific review to earn Regen Registry accreditation and its own credit class. It is audited by Carbon Direct and Nova-Cert, verified to ISO 14065, and rated by BeZero in the global top 30%. We were also commissioned by WWF to write the soil health measurement paper for Codex Planetarius, published in December 2025.
Yes. It is supplier-specific data, measured to the standards their auditors will use from 2027, and every round is measured to full Registry standard whichever tier you are on. If your buyer asks for emissions as well, that is tier 02 and it uses the same measurement.
The finance and insurance industries have begun to value evidenced soil resilience through rate reductions on working capital and mortgages. We are actively working to widen access to those risk-rated products, and an annual measured record against your own baseline is the evidence they ask for.
That is exactly what measurement is for. Soil carbon loss is invisible until a poor season exposes it as yield you cannot explain. Seeing it in the year it happens means the correction is a rotation change rather than a rebuild.
Cost and commitment
Pricing depends on the size of the holding, the number of fields and the tier you choose. Larger holdings cost materially less per hectare, because the fixed work of a round is spread over more ground. Send us your SBI number and your hectares and we will send a written quote within two working days.
Yes. We have separated measurement from reporting and hold registry submission back until there is direct demand for insets or offsets. That, and the scale of monitoring across eleven countries, has brought the cost of an annual round well below what the same measurement cost inside a full carbon project.
Because one rate would be wrong for most farms. The fixed work of a round is spread over the area measured, so the honest answer depends on your holding and the number of fields. What sets the price per hectare explains the three things that move it.
Our minimum project area is 150 hectares, and it does not have to be your whole farm. Many farms start with the block they are changing, or the one they are least sure about, and add fields in a later round. See what 150 hectares means in practice.
A small deposit secures your place in the sampling season. The balance for the baseline round is invoiced once that round is complete, and annual monitoring is invoiced each year on your normal account. There are no instalments to manage.
No lock-in, and never a commission. We are paid for the measurement, not a share of your carbon, so our advice is not biased by what earns us more. If you stop working with us you take your baseline and every measurement with you.
Timing and getting started
In the autumn and winter, when fields are between crops. The 2026 autumn-winter window is open until the end of February 2027.
Soil moves with the season: roots grow and die back, residue breaks down, moisture and biology change. Sampling at the same point each year is what makes the difference between rounds your management and that year of weather, rather than the calendar. More in why soil carbon is measured once a year.
Your baseline moves back a year, with sampling beginning again in autumn 2027. That is another year of decisions made without knowing which way the soil is going.
Your SBI number and your hectares are enough for a written quote. After that, a short call agrees which fields are in and how the sampling team gets access.
The ones where you are changing something, the ones you are least sure about, or the ones a buyer or a lender is asking about. Fields added in a later round get their own baseline from the round they join and are then measured in the same window as the rest.
Yes. More than 250 projects in 11 countries, covering arable, grassland restoration, re-wilding and afforestation, all measured the same way to the same standard.
Reporting, credits and buyers
When your supply chain asks for it. Tier 02 adds a full IPCC Tier II emissions calculation, reported to SBTi and GHG Protocol standards, so you can show both sides of the ledger: what the farm emits as well as what it removes.
Registry submission is now held back until there is direct demand for insets or offsets, which is what brings the cost of routine monitoring down. Every round is still measured to full Registry standard, so stepping up to a carbon project is a decision rather than starting again.
Yes, through tier 03. A registry-accredited project, verified removals issued in your name, sold on your terms and commission-free.
An inset stays inside the supply chain that produced it and is usually bought by your own buyer to reduce the footprint of what they source from you. An offset is sold outside that supply chain. Both come from the same measured removals.
Buyers who audit what they buy. Our credits are measured, net-negative removals with an immutable ledger behind them, and they have been bought by organisations including the Mercedes-AMG PETRONAS Formula One team.
Yes. We monitor projects for developers, estates and corporate supply chains as well as individual farms, with the same method and the same evidence standard. See for project developers.
