Frequently Asked Questions
What is a carbon credit serial number?
It is a unique registry identifier or part of an identifier range used to distinguish issued units and follow their lifecycle status.
What if I purchase less than one tonne?
The marketplace should document how the fractional allocation maps to underlying registry units or a larger retirement and link the certificate to that evidence.
Is a QR code sufficient proof?
A QR code is only a convenient link. The destination registry record and its project, quantity, beneficiary, purpose and status fields provide the substantive evidence.
