Formula

(Number of sourced products for which an environmental life cycle assessment has been conducted / Total number of sourced products) × 100

Apply the source-defined TNFD sector-guidance method within the stated reporting boundary. This is a standalone additional-sector outcome metric expressed as a percentage of a defined sourced-product population. It is not equivalent to product life-cycle GHG totals or supplier environmental-assessment coverage, and no shortlisted existing metric matches its construct and boundary.

Evidence and status sources

Sustopedia checked each record-specific claim directly against primary publisher material. Labels distinguish current measurement authority from future compatibility and corroborative, legal, edition, or method status context. Corroborative evidence can support a stated limitation but cannot establish the core measurement by itself.

Interpretation boundaries

Method disclosures required

Source-edition basis: TNFD sector guidance, Final English sector guidance collection through August 2026 (17 documents).

  • Define the sourced-product population used as the denominator.
  • Disclose the criteria used to determine that an environmental life cycle assessment has been conducted.
  • Disclose the aggregation basis used for the percentage when products are heterogeneous.

Record-specific limitations

  • The source extract does not define product eligibility criteria, the assessment standard, or whether the percentage is count-weighted, volume-weighted, or value-weighted.
  • The source extract does not specify the life-cycle stages required for the environmental life cycle assessment.

Interpret this metric with the stated reporting boundary, period convention, value shape, and unit. Results prepared with different boundaries or conventions may not be directly comparable.

Measurement evidence supports the core record-specific claims described above. Corroborative evidence can support limitations, while compatibility and status sources provide their separately labelled context. None of these cards by itself determines an organisation's legal applicability, filing readiness, assurance status, or compliance conclusion.
