Carbon Credit Transparency Ledger

View carbon credits recorded through CrbonLabs, including credit inventory, registry serials, retirement status, and retired credit proof. This public ledger helps customers and partners review registry serial availability, contribution records, and evidence tied to approved carbon contribution activity.

Evidence & Assurance

This page publishes our full allocation ledger with no authentication. Here is exactly what that evidence proves, and what it doesn't.

Independently checkable, by anyone, against a third party

Each credit is an ERC-721 token minted by the BCarbon registry on Polygon. The mint, ownership, and our retirement (burn) of that token are all publicly verifiable on Polygonscan, independent of us.
The underlying project's Validation Report (Jan 2025) ↗ and Verification Report (Mar 2025) ↗ are issued and hosted by the BCarbon registry, not by us. A licensed Professional Engineer independently confirmed the two wells were physically plugged and that post-plugging tests found no methane emissions.
Both the Validation and Verification Reports for this project were prepared by the same independent firm (ALL Consulting); we have not separately engaged a second verifier.
Each buyer receipt's Ed25519 signature proves it was issued by CrbonLabs and has not been altered since.

Publicly disclosed by us, but not third-party audited

Once a token is retired, splitting its 1,000 kg into fractional allocations across buyers happens in our database. We publish that allocation table in full — every serial, every kg, every buyer, with totals reconciled on this page — so anyone can verify our arithmetic against itself. This is not the same as an independent auditor checking our records against an outside source. If we ever over-allocated or double-counted, the public totals would break visibly, immediately.

On the headline reduction figure

The 39,837 tCO₂e figure cited in BCarbon's registry documentation is a 20-year projection, not a quantity confirmed to have occurred to date. It should not be characterised as a "verified reduction achieved." What is independently verified: the plugging event itself and the absence of ongoing methane emissions.
Retirement of a credit does not itself constitute a claim of carbon neutrality. Buyers are responsible for ensuring their own claims comply with BCarbon's program rules and claim-limit terms.
