Independent verification of waste and residue-based biofuels
Measurement answer
What this metric measures
Total volume and reported proportion of waste and residue-based biofuels independently verified through third-party audits, with audit-type and higher-risk-region coverage context.

Disclosure form
No single formulaReport the source-defined result with its stated fields and method disclosures. The source specifies two reportable outputs—verified volume in tonnes and verified proportion in percent—and requires contextual audit information. They are retained as one structured metric family rather than flattened into a single rate because the volume and percentage are independently reported fields and the percentage denominator is not supplied in the extracted evidence. No shortlisted metric matches this biofuel-verification construct and structured output.

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.

- Disclose the reporting scope and the biofuel volumes included.
- Disclose the basis and denominator used to calculate the reported verified percentage.
- Disclose the third-party audit types accepted, including treatment of accredited certification audits and unannounced audits.
- Disclose the approach used to identify higher-risk regions and describe audit coverage in those regions.
Record-specific limitations
- The extracted evidence does not specify the denominator used for the reported percentage; reporters must disclose it.
- The extracted evidence does not define a region-risk taxonomy or a threshold for higher audit coverage in higher-risk regions.
- The metric reflects third-party audit verification and does not independently establish the sustainability performance of the underlying biofuels.
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.
