Digital Conformity Credential
The RBTP Knowledge Base is evolving weekly as part of our pilot programs with RBA members. We’d love your input — submit feedback or help shape the protocol in real time by joining a pilot.
Digital Conformity Credential (DCC): Overview​
For vocabularies, JSON-LD contexts, and schemas see the UNTP DCC pages.
A Digital Conformity Credential (DCC) is a core credential defined by the UN Transparency Protocol (UNTP). Issued by an authorised conformity-assessment body (CAB), it delivers a verifiable assessment of a product or facility against a named standard or regulation and can include measured values and secure links to supporting evidence.
In RBTP, DCCs supply the independent verification layer for claims made in Digital Product Passports (DPPs) and facility records (DFRs/DEFRs). An example familiar to RBA members is an RMAP audit certificate: the Responsible Minerals Assurance Process issues its assurance as a DCC and links that credential to upstream smelters or refiners.
🔍 Key Points​
| Feature | UNTP requirement |
|---|---|
| Authorised issuer | DPCC-01 — credential must be signed by an accredited body. |
| Assurance & accreditation level | DPCC-02 — identifies the nature of the issuer’s authority. |
| Object of conformity | DPCC-03 — unambiguously identifies the assessed product or facility. |
| Reference standard / regulation | DPCC-04 — cites the criteria that were tested. |
| Conformance statement | DPCC-05 — declares pass/fail against the criteria. |
| Measured metrics (optional) | DPCC-06 — may include actual values (e.g., CO₂ intensity). |
| Evidence links (optional) | DPCC-07 — may link to auditable evidence with hash and encryption info. |
✅ Summary​
- The DCC is the verification credential in UNTP and underpins trust in RBTP sustainability claims.
- It is a W3C Verifiable Credential that references the assessed object, the governing standard, and (optionally) detailed results and evidence.
- Sector-specific attestations—such as RBA’s RMAP certificates—are simply profile-specific DCCs that plug into the same UNTP model.
- Linking DCCs to DPPs, DFRs, and Traceability Events creates an auditable chain from declaration to third-party proof.
