Formula
Deforestation- and conversion-free sourced product weight share (%) = (weight of sourced products verified as deforestation- and conversion-free / total weight of sourced products) × 100.Apply the source-defined TNFD sector-guidance method within the stated reporting boundary. This is a reportable percentage outcome metric. It remains distinct from the shortlisted sourced-volume-share metric because the source specifies a weight-based measure and verified status; it also remains distinct from the production-volume metric because its population is sourced products.

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.

Record-specific limitations
- The extracted evidence does not specify a cutoff date, verification standard, sourcing tiers, geography or treatment of mixed-origin products.
- The measure is limited to sourced products and should not be generalized to controlled or managed production without separate evidence.
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.
