Traceability levels of primary biomass feedstocks
Measurement answer
What this metric measures
Reports the type, weight and proportion of primary biomass feedstocks by traceability level, with origin and chain-of-custody disaggregation.
Specification
Metric specification
- Result format
- Structured table
- Unit
- tonnes and percent (%) — source-defined reporting unit

Disclosure form
No single formulaReport the source-defined result with its stated fields and method disclosures. AF.C22.0 is a standalone structured sector metric with explicitly reportable feedstock weights, percentages and traceability attributes. It is distinct from biomass-harvest metrics because its reported construct is supply-chain traceability of sourced primary biomass feedstocks.

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.

- Describe the traceability categories used.
- Disaggregate results by primary biomass feedstock type and chain-of-custody model.
- Identify country, sub-national and specific production-site traceability, as applicable.
- Where certified feedstocks are included, disclose the certification scheme and demonstrate that its traceability and chain-of-custody requirements are met.
Record-specific limitations
- The supplied extract does not specify a reporting-period convention.
- Traceability categories and applicable chain-of-custody requirements must be applied as specified in the TNFD sector guidance.
- Certified feedstocks are includable only where they meet the stated traceability and chain-of-custody requirements.
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.
