We do not sell carbon credits
We check the one you are about to buy. No inventory, no commission, no preferred counterparty, so nothing here has a reason to point you anywhere in particular.

What the database covers
Every project below is one somebody published. If a credit you are offered is not in here, that is the first thing worth asking about.

Five things to establish before money moves
Each of these is answerable from the public record, and each is a way a carbon purchase actually goes wrong.
The project is real and is where it says it is
A name and a registry are not an identifier. Resolve the credit to a specific project record, then confirm the developer, the country and the crediting period match what you were told.
Registry LookupIt is in good standing today
Projects get suspended, withdrawn, and put on hold. A record that was clean when the offer was written may not be clean now, and the status is published.
Project AuditorThe vintage you are being sold was actually issued
Issuance is recorded per vintage year. A 2023 vintage offered from a project that issued nothing in 2023 is the simplest fraud in this market, and the simplest to catch.
Registry LookupThe methodology has been independently assessed
An independent integrity council assesses crediting methodologies against a set of core principles. What it concluded about the methodology behind your credit is public, and it is the question that decides whether the tonne was ever real.
Methodology LabThe tonnes are not already retired
A retired tonne has been claimed by somebody. Retirement is recorded against the serial, and buying a retired credit buys nothing at all.

Why there is no price list on this page
What a voluntary carbon credit actually traded at is not public. It sits with commercial price reporting services, and no free source carries it. A site that prints one anyway is either quoting a number it cannot support or quoting one somebody paid to place.
Compliance allowance prices are different, because governments publish them. So those we show, exactly as published, with the date attached.
Across 19 compliance markets. The same tonne, priced by different governments.
