Value structure

Dimensions and units

Unit
percent (%) of sourced organisms — source-defined reporting unit
Reporting basis
Reporting period; period specification is not provided in the supplied extract.

Unit meaning: Values use percent (%) of sourced organisms under the disclosed TNFD sector-guidance method, reporting period and boundary.

Published dimensions

  • organism sourced
  • point of origin

Calculation method

Formula information

Status
Specified
Formula type
Percentage

Formula

(Number of sourced organisms traceable to their point of origin / Total number of sourced organisms) × 100

Apply the source-defined TNFD sector-guidance method within the stated reporting boundary. F.A22.1 explicitly specifies a reportable percentage outcome for sourced organisms. It is not equivalent to narrative disclosures about traceability systems because it measures the share of organisms with origin traceability.

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).

  • Describe the method used to determine whether a sourced organism is traceable to its point of origin.
  • State the population of sourced organisms used as the denominator.
  • Describe the point-of-origin information used for traceability assessment.

Record-specific limitations

  • The supplied extract specifies traceability to point of origin but does not define a reporting-period convention.
  • The supplied extract does not provide a prescribed taxonomy, geographic granularity or verification method for sourced organisms.

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.
