Verified waste- and residue-derived feedstock volume and share
Measurement answer
What this metric measures
Quantity and share of waste- and residue-derived feedstock volumes verified through analytical or chemical methods to confirm origin and authenticity, with the verification approach, governance arrangements, and testing frequency disclosed.

Disclosure form
No single formulaReport the source-defined result with its stated fields and method disclosures. AF.A23.0 requires reportable output values—a verified feedstock quantity in tonnes and its percentage of total waste- and residue-derived feedstock volume—alongside mandatory methodological information. Verification methods, governance, and testing frequency are retained as structured method disclosures rather than treated as independent metrics. The shortlisted waste metrics measure waste generation or waste treatment and do not match this feedstock-verification construct or boundary.
Verified sources
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 analytical or chemical verification approach used to confirm feedstock origin and authenticity.
- Describe governance arrangements for the verification process.
- Disclose testing frequency.
- Identify relevant waste- or residue-derived feedstock types, such as used cooking oil or palm oil mill effluent.
Record-specific limitations
- Verification confirms feedstock origin and authenticity according to the reported analytical or chemical approach; it does not independently establish the sustainability performance of the feedstock.
- Comparability depends on feedstock classifications, verification methods, governance arrangements, and testing frequency.
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.
