Plausibility checks for waste- or residue-based biofuel yields
Measurement answer
What this metric measures
Reports biofuel-yield plausibility-check activity, red flags, and the treatment of flagged volumes for waste- or residue-based biofuels.

Published dimensions
- result type: plausibility checks performed, red flags identified, or flagged-volume disposition
- flagged-volume disposition: rejected, downgraded, reclassified, or reported to certification bodies
- context-specific benchmark used

Disclosure form
No single formulaReport the source-defined result with its stated fields and method disclosures. The source specifies multiple related reportable outputs rather than a single calculation operand. They are retained as one structured disclosure family because all outputs concern the same plausibility-check process and flagged-volume treatment. The mixed count and percentage outputs are preserved rather than flattened into one scalar.
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.

Source-edition basis: TNFD sector guidance, Final English sector guidance collection through August 2026 (17 documents).
- Define the waste- or residue-based biofuel yields and volumes covered.
- Describe the context-specific benchmarks used for plausibility checks.
- Define a plausibility check and a red flag.
- State how flagged volumes were classified as rejected, downgraded, reclassified, or reported to certification bodies.
- State the denominator used for each percentage of flagged volumes.
Record-specific limitations
- The disclosure records verification activity and treatment of flagged volumes; it does not by itself establish the sustainability, legality, or actual origin of biofuel feedstocks.
- Comparability may be affected by the context-specific benchmarks applied and by differences in the definition of a check or red flag.
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.
