The accreditation body's published register is queried at verification- publication time; the response is cached for the TTL declared in the accreditation body's HTTP caching headers. A withdrawn or suspended reference returns `410 Gone` for the operator's verification-publication endpoint and `200 OK` with a `withdrawn: true` flag for the public retrieval endpoint. ### §1.2 ISO/IEC 17065 register for Type I schemes Every Type I licence carried by the operator is verified against the issuing scheme operator's ISO/IEC 17065:2012 accreditation. The operator's API queries the scheme's published register on each retrieval after the caching TTL. ## §2 EPD Programme Operator Integration The operator binds every EPD record to a programme operator's published instructions under ISO 14025 §7. The programme operator's endpoint is published at the operator's discovery document and is queried at EPD publication and at retrieval. The PCR editor's endpoint, where separate from the programme operator, is queried for the PCR's review-status flag declared in PHASE-3 §2.2. ## §3 Construction-Project Integration ### §3.1 EN 15978 building-level summary ingestion An EPD whose `materialFamily` is a construction- product family carries an EN 15978-compatible machine-readable summary in the response envelope. The summary is consumed by a building-level assessment tool to compute the per-building environmental performance per EN 15978 §6. The summary is signed using the operator's public-key set so that the tool can validate the binding without re-fetching the EPD. ### §3.2 EU Construction Products Regulation linking A construction product placed on the EU market under EU Regulation (EU) 305/2011 carries a CE marking with a Declaration of Performance. The operator's API carries the link from the material record's `identifierBindings` to the manufacturer's published Declaration of Performance so that a downstream consumer can verify the CE-marking compliance of the EPD- covered product. ## §4 Public-Procurement Integration A public-procurement authority operating an environmentally-preferable-purchasing programme queries the operator's API for the materials satisfying the programme's environmental criteria. The query envelope carries the programme's PCR reference, the required indicator thresholds, and the validity-period filter; the response is an RFC 8288 `Link`- paginated collection of material records that satisfy the criteria. ## §5 Carbon Border Adjustment Mechanism Integration ### §5.1 CBAM customs-declaration linking An organisation in scope of EU CBAM Regulation (EU) 2023/956 publishes a per-product embedded- emissions declaration that links the carbon footprint computed under ISO 14067:2018 to the CBAM declaration filed with the customs authority. The operator's API carries the per- product CBAM report identifier and the linked carbon footprint record so that the customs authority can verify the embedded-emissions value against the carbon-footprint computation. ### §5.2 Verified embedded-emissions discipline The CBAM declaration's verifier reference is bound to the operator's verifier-of-record under ISO 14064-3:2019. A change of verifier is recorded as a new chain-of-custody event under PHASE-3 §6 so that the customs authority's audit trail is preserved across the verifier change. ## §6 Consumer-Protection Authority Integration A Type II self-declared claim is reviewable by the relevant consumer-protection authority under the operator's jurisdiction. The operator's API publishes the claim's verbatim text, the evaluation method, and the evidence artefacts so that the authority can validate the claim against ISO 14021 §7 and the jurisdiction's green-claims regulation. Where the operator is in scope of the EU Green Claims Directive (when it enters force), the operator publishes the ex-ante substantiation file referenced by the directive. ## §7 KR-Jurisdiction Integration ### §7.1 KS I ISO 14025 / KS I ISO 14021 adoption A KR-jurisdiction operator declares the KS I ISO 14025 and KS I ISO 14021 adoption references in the programme record's `governingFrameworks`. The KR Environmental Industry and Technology Institute (KEITI) operates the KR Eco-Label scheme register; the operator's API queries the KEITI register on Type I licence publication and on each retrieval after the caching TTL. ### §7.2 KR Carbon-Disclosure linkage An organisation participating in the KR Greenhouse Gas Inventory and Reporting System carries the inventory's per-period reference in the GHG record's `reportingPeriod`. The operator's API does not gate publication on the inventory's review status — the publication is informational and is reviewed by the operator's regulatory- affairs team under the operator's quality- management discipline declared in PHASE-3 §9. ## §8 Public Retrieval and Re-Issuance ### §8.1 Public EPD retrieval A public consumer (a buyer evaluating a bid, a designer integrating the EPD into a building- level assessment, a researcher referencing the LCA in a publication) retrieves the EPD record at `/v1/epd-records/{epdId}` without authentication; the response carries the public fields and the EN 15978 summary. ### §8.2 Verifiable-credentials re-issuance A verification reference can be re-issued into a downstream system as a W3C Verifiable Credential. The credential carries the accreditation body's issuer identifier, the accreditation reference, the scope of the accreditation, the certificate's expiry, and the issuing date; the credential is signed using the accreditation body's public-key set so that a downstream verifier can validate the credential without contacting the accreditation body directly. ## §9 Audit and Conformity-Assessment Integration ### §9.1 ISO/IEC 17021-1 management-system audit The operator's quality-management system declared in PHASE-3 §9 is audited under ISO/IEC 17021-1 by an accredited certification body. The audit result is stored in the operator's audit envelope and is referenced from the programme record's `accreditationStatus`. The certification body's public-key set is published at the certification body's endpoint; the operator's API verifies the audit certificate's signature against the certification body's public key on retrieval. ### §9.2 ISO/IEC 17065 product certification Where a Type I ecolabel is itself a product- certification deliverable, the certification body issuing the label operates under ISO/IEC 17065: 2012. The certification body's marking, the scope of certification, and the certified product's identifier are published in the licence envelope so that a downstream consumer can verify the certification scope before relying on the label. ## §10 References (consolidated) The references list across PHASE-1 to PHASE-4 is the canonical citation set for the WIA-eco- friendly-material standard. Implementations cite the standards by their issuing organisation (ISO, IEC, IETF, W3C, EU regulatory text, KS) and the publication year so that a downstream consumer can locate the authoritative text. Updates to a cited standard (for example, a new amendment to EN 15804) trigger an internal review cycle in the operator's quality-management discipline declared in PHASE-3 §9 before the new revision is bound into the operator's enumeration set. ## §11 LCI Database Aggregation Integration The operator's LCI dataset references published in PHASE-1 §4 may bind to one or more LCI database publishers operating under an industry- recognised peer-review scheme. The operator publishes the binding from the LCA record's `inventoryDataset` to the LCI database's publication endpoint so that a downstream consumer can verify the dataset's provenance without re-running the LCA. Where the operator runs its own LCI dataset (a sectoral cooperative, an industry association running a shared inventory), the operator's publication endpoint mirrors the binding contract. ## §12 Cross-Programme EPD Federation ### §12.1 Federation discovery An operator participating in a federation of programme operators publishes the federation membership list in the discovery document. The list carries the federation's name, the federation's published instructions (the meta- PCR if any), and the per-peer mutual-recognition agreement reference. The federation's discovery document is signed by the federation's secretariat so that a downstream consumer can validate the federation membership independently. ### §12.2 Federated query envelope A federated query is forwarded to every peer in the federation; each peer responds with the subset of its EPD register satisfying the query. The aggregator deduplicates the result by the EPD's content hash and presents the union to the querying consumer. The federation discipline preserves each peer's accreditation reference so that the consumer can trace each EPD back to the originating programme operator. ## §13 Verifier-Pool Marketplace Integration A verifier listed under ISO 14065:2020 publishes its verification offer (scope, accreditation reference, fee schedule, geographic coverage) to a verifier-pool marketplace. An operator seeking verification queries the marketplace by the required scope (organisation-level GHG, project- level GHG, EPD verification, Type I licence verification) and receives a list of eligible verifiers. The marketplace does not decide selection; it carries the offer set and the operator selects per its quality-management procurement policy declared under ISO 9001 §8.4. ## §14 KR Green-Procurement Integration The KR Public Procurement Service operates a Green Public Procurement scheme that gives preference to materials carrying a KR Eco-Label or an equivalent foreign Type I licence. The operator's API carries the binding from the KR-jurisdiction material record to the KR Eco- Label register so that a public buyer querying the procurement system can verify the eco-label status without leaving the procurement workflow.
