How our registry works
The Isometric registry ensures rigorous verification, transparent tracking, and permanent retirement of carbon certificates. Every carbon certificate moves through four public events.
- 01
Issued after independent validation against the Isometric Standard.
- 02
Delivered from suppliers to buyers. All parties, volumes, and dates are public.
- 03
Transfer(optional)
Transferred between two buyer organizations, with detailed transaction history.
- 04
Retired by the end buyer, permanently closed and publicly recorded.
Why trust our registry
Every certificate is audited by an independent third party against a rigorous scientific standard, and recognised by the world’s leading carbon market bodies.
The Isometric standard
A comprehensive scientific framework covering all carbon removal and reduction pathways, developed through public consultation and peer review.
Read the standardIndependent VVBs
Every project is independently audited by Validation and Verification Bodies before a single certificate is issued. Isometric does not verify its own projects.
