UNTP Digital Product Passport¶

The UN Transparency Protocol (UNTP) defines a cross-sector DPP format wrapped as a W3C Verifiable Credential (VCDM 2.0) in JSON-LD.

Source¶

Spec: uncefact.github.io/spec-untp/docs/specification/DigitalProductPassport
Version: 0.6.0
JSON Schema: https://test.uncefact.org/vocabulary/untp/dpp/untp-dpp-schema-0.6.0.json

Structure¶

The UNTP DPP is a Verifiable Credential with this top-level shape:

{
  "type": ["DigitalProductPassport", "VerifiableCredential"],
  "@context": ["https://www.w3.org/ns/credentials/v2", "..."],
  "id": "...",
  "issuer": { ... },
  "validFrom": "...",
  "validUntil": "...",
  "credentialSubject": {
    "type": ["ProductPassport"],
    "product": { ... },
    "emissionsScorecard": { ... },
    "circularityScorecard": { ... },
    "materialsProvenance": [ ... ],
    "conformityClaim": [ ... ],
    "traceabilityInformation": [ ... ],
    "dueDiligenceDeclaration": { ... }
  }
}

credentialSubject fields¶

product¶

Field	Type	Description
`id`	URI	GS1 Digital Link or equivalent
`name`	string	Product name
`registeredId`	string	GTIN + serial
`description`	string	Product description
`productCategory`	array	UN CPC classification
`producedByParty`	object	Manufacturer identity
`producedAtFacility`	object	Factory identity
`productionDate`	date	Manufacturing date
`countryOfProduction`	string	ISO 3166-1 alpha-2
`serialNumber`	string	Item-level serial
`dimensions`	object	Weight, length, width, height, volume

emissionsScorecard¶

Field	Type	Description
`carbonFootprint`	number	CO2e per declared unit
`declaredUnit`	string	Unit (KGM, kWh, etc.)
`operationalScope`	enum	`CradleToGate`, `CradleToGrave`
`primarySourcedRatio`	number (0-1)	Ratio of primary vs. secondary data

circularityScorecard¶

Field	Type	Description
`recyclableContent`	number (0-1)	Fraction recyclable
`recycledContent`	number (0-1)	Fraction from recycled sources
`utilityFactor`	number	Functional utility ratio
`materialCircularityIndicator`	number (0-1)	Ellen MacArthur MCI

materialsProvenance¶

Array of materials, each with:

Field	Type	Description
`name`	string	Material name
`originCountry`	string	ISO country code
`massFraction`	number (0-1)	Fraction of total mass
`mass`	object	Absolute mass with unit
`recycledMassFraction`	number (0-1)	Recycled fraction
`hazardous`	boolean	Hazardous substance flag

conformityClaim¶

Array of claims/certifications with conformance status, topic, assessment date, and declared values.

traceabilityInformation¶

Supply chain events with cryptographic hashes for tamper evidence.

Key difference from Battery Pass¶

The UNTP DPP is sector-agnostic — it works for any product. The Battery Pass schema is battery-specific with domain fields like SoH, cycle count, and cell chemistry. In practice, a battery DPP could use UNTP as the envelope and Battery Pass sub-models for the detailed content.
