Assurance for the carbon claims that move money.

We verify batch-level product carbon footprints and issue the labels that let agricultural goods cross borders under scope 3 rules. Independent of the software, the hardware and the seller — that is the only reason a buyer should accept our signature.

What we do

Three things, kept strictly apart

Verification, assurance and advisory are different services with different liability. We only sell the first two, because selling the third to the same client invalidates both.

Scope 01

Product carbon footprint

ISO 14067 verification of a single production batch: boundary, functional unit, emission factors, allocation rules and uncertainty, each re-derived rather than accepted.

Verification scope →
Scope 02

Carbon labels & registry

Issuance of a hash-frozen label with a public registry entry. Anyone can recompute the hash in their own browser without trusting our server.

Label specification →
Scope 03

Data & ledger assurance

Metrology traceability, sampling coverage and hash-chained records. We assure the evidence chain, not the accuracy of somebody's model.

How it works

Four stages, fixed in advance

The stages and the end points are registered before any data is collected. That is what makes the result auditable rather than arguable.

Insights

Published method, open to challenge

Everything we rely on is written down with a version number and a challenge window. If a rule is wrong, the way to beat it is to submit a counter-example.

Bring us a batch. We will tell you what cannot be verified.

Scoping is free. If the data will not support a defensible label, you will hear that before you pay for anything.
