**UNTP Relationship**

UNTP does not re-invent any of the criteria in the ISO PCDS. Rather the UNTP Digital Product Passport provides a simple mechanism to digitalise product product circularity data in a way remains ISO-59040 conformant. The UNTP Digital Product Passport data model includes the organisation, facility, and product meta-data required by ISO-50940. The `Declarations` structure within the UNTP DPP data model can be used to convey each specific circularity criteria defined by ISO-59040. Since UNTP DPPs are both human and machine readable and can carry other sustainability information such as carbon footprint, product manufacturers can issue UNTP DPPs with confidence that the single DPP can conform to multiple sustainability standards and be equally valuable to human and machine verifiers.

| ----- | ------------------------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ------------------------------------------------------------------- |
| TI.01 | Trust anchors | Trust in truth of sustainability claims can be established by third party audits, or by attestation of trusted authorities, or by long standing evidence of sustainable behaviour. The UNTP MUST provide a mechanism to link ESG claims to any or all of these "trust anchors" so that downstream actors can have confidence that claimed ESG performance is true. | [Trust anchors](../design-patterns/TrustGraphs.md) |
| TI.02 | Identity integrity | Identifiers of businesses, locations, products, and shipments underpin the UNTP. Therefore, the UNTP MUST provide a mechanism to verify that ESG claims made about products or locations or entities are made by actors that are genuine owners of the identifiers or their authorised delegates - so that downstream actors can be sure that ESG claims are made by parties genuinely authorised to do so. | [Identity Anchors](../specification/IdentityResolver.md)) |
| TI.02 | Identity integrity | Identifiers of businesses, locations, products, and shipments underpin the UNTP. Therefore, the UNTP MUST provide a mechanism to verify that ESG claims made about products or locations or entities are made by actors that are genuine owners of the identifiers or their authorised delegates - so that downstream actors can be sure that ESG claims are made by parties genuinely authorised to do so. | [Identity Anchors](../specification/IdentityResolver.md) |
| TI.03 | Accreditation | Third party audits and assessments add trust. But if the verifier does not know the auditor / certifier then there's a risk that define a mechanism to link third party certifiers to the accreditation authrority under which they perform their work so that downstream actors can trust the certificates even when they do not know the certifiers. | [Conformity](../specification/ConformityCredential.md) |
| TI.04 | Verification of documents | The UNTP MUST define standard and interoperable mechanisms to prevent spoofing or tampering of any documents issued by upstream actors so that downstream actors can be confident that ESG credentials were genuinely issued by the claimed identity and have not been altered in any way. | [Verifiable Credentials](../specification/VerifiableCredentials.md) |
| TI.05 | Verification of graphs | Evidence of ESG performance in supply chains is not concentrated in one document but rather is distributed along the entire value chain. The UNTP MUST define a mechanism to describe and verify the collection of evidence that is available from chains of linked documents so that downstream actors can verify the full ESG footprint and provenance data for any shipment. | [Trust graphs](../design-patterns/TrustGraphs.md) |
