Claim subject and wording What is claimed about what.
Claim statement
The subject, wording and audience of the claim.
Subject and scope
The product, organisation or activity and the unit the claim refers to.
- Which product, organisation or activity does this claim refer to?
- Which declared or functional unit does a quantified claim use?
Wording
The exact text of the claim and where it is shown.
- What exactly does the claim say, and where is it presented to buyers or the public?
- Does the claim state a comparison, a reduction or a neutrality, and against what baseline?
Quantification How a footprint figure was calculated.
Method and boundary
Standard, system boundary, data sources and allocation.
Calculation basis
Method, boundary and data quality behind the figure.
- Which standard or product category rule was used, and which life-cycle stages are included?
- What share of the result rests on primary data rather than secondary data?
- Are offsets or removals counted, and are they shown separately from emissions?
Substantiation Whether the claim is backed and checked.
Verification
Independent review and validity of the claim.
Verification status
Who verified the claim, at what assurance level and until when.
- Was the claim verified by an independent party, and at what level of assurance?
- For which period is the claim valid, and when must it be recalculated?

What it is Filled
A sustainability claim is a statement about the environmental performance of a product, organisation or activity; a product carbon footprint (PCF) is its quantified form, giving greenhouse gas emissions and removals per declared unit over a stated life-cycle boundary. The claim is the statement with its method, data and verification; the emissions themselves are physical flows described elsewhere.
Why it exists Filled
Environmental claims and product carbon footprints with method, boundary and verification.
Distinguishing features Filled
- A claim is a statement with a method and evidence, not the emission flows it describes.
- A product carbon footprint is tied to one declared unit and a stated life-cycle boundary.
- Distinct from an organisation's sustainability disclosure, which reports on the whole entity for a period.
- Offsets and removals are recorded apart from the product's own emissions.
What robots and AI may and may not do Filled
Must not
- Generate or publish environmental claims that the evidence does not support.
- Present offset-based neutrality as a reduction of the product's own emissions.
- Compare footprints calculated with incompatible methods or boundaries without saying so.
- Alter a verified footprint figure without starting a new verification.
- Hide the share of estimated or secondary data behind a single precise figure.
Only with a human decision
- Approving a claim for public or marketing use.
- Signing off a footprint as verified.
- Withdrawing a claim already communicated to buyers or regulators.
May
- Record a claim with its subject, wording, method, boundary and verification.
- Exchange footprint figures with trading partners in agreed data formats.
- Compare claims only when units, boundaries and methods are compatible.
- Flag claims that lack evidence, verification or a valid period.
Moral aspects Filled
- Misleading claims divert buyers and capital away from real emission reductions.
- Suppliers in weaker positions may be pushed to supply data at their own cost.
- Honest claims help buyers and public bodies make choices that matter for the climate.
Who is affected
- Consumers and business buyers
- Suppliers along the value chain
- Competitors making honest claims
- Regulators and consumer protection bodies
Owners Filled
Steward
The sustainability or product compliance lead who answers for the claim on behalf of the claimant.
Master systems
- Life-cycle assessment database
- Product data management system
- Sustainability reporting system

What else AI and robots need to interact with it Filled
Identity and identifiers required Filled
- A claim is identified by the claimant's record identifier with the product identifier, such as a GTIN, and a version.
- Verified claims also carry the verifier's statement or certificate reference.
Direct properties not applicable Not applicable
Not applicable
A claim is information; the footprint figure, unit and boundary are recorded in its structure, and the underlying physical flows belong to the emission model.
Recognition optional Filled
- Marked by environmental wording, a figure in CO2 equivalent per unit, a label or a reduction promise.
- Often confused with an organisation-wide footprint, an ecolabel or an offset certificate.
Capabilities and actions required Filled
- Footprints can be passed along the supply chain and aggregated into product footprints.
- Claims can be recalculated when data, methods or products change.
- Claims can be checked against the evidence and verification on record.
Hazards and failure modes required Filled
- Greenwashing through vague or unsubstantiated wording.
- Double counting of reductions or offsets across claimants.
- False precision when estimates are presented as measured figures.
Standards and interfaces required Filled
- ISO 14067 for product carbon footprints and ISO 14021 for self-declared claims.
- GHG Protocol Product Life Cycle Accounting and Reporting Standard.
- Partnership for Carbon Transparency Pathfinder data exchange specification.
Context of use required Filled
- Used in product marketing, procurement, supply chain reporting and product passports.
- Consumer protection rules on environmental claims apply, including EU rules against greenwashing.
