Registries help create an identifiable record.
A registry can assign a unique identity to a project and to issued units, then record transactions and retirement. This creates an evidence trail that helps prevent confusion about which credits exist and how they have been used.

A registry record is one important layer of diligence.
A public record can help readers locate project documents, issuance information, and retirement details. It does not replace understanding the assumptions, methodology, or context used to quantify an outcome.

Traceability supports clearer claims.
When a public claim involves credit use, being able to identify the relevant credit, registry, and retirement record makes the claim easier for others to understand and scrutinize.

Open guideCommon questions
What does retirement mean?
Retirement typically records that a unit has been removed from circulation for a stated use, so it should not be transferred or claimed again within that registry system.
Do all registries work identically?
No. Readers should review the relevant program rules, public interfaces, documentation, and project-level information.
