Unit meaning: Values use bbl under the disclosed TNFD sector-guidance method, reporting period and boundary.

Table fields and units

  • Qualifying hydrocarbon spills (count)
  • Total qualifying hydrocarbon spill volume (bbl)
  • Qualifying spill volume affecting sensitive locations (bbl)
  • Recovered hydrocarbon volume (bbl)

Published dimensions

  • spill qualification threshold: greater than 1 bbl
  • impact context: sensitive location affected
  • recovery status: recovered hydrocarbon volume

Disclosure form

No single formula

Report the source-defined result with its stated fields and method disclosures. The source specifies a reportable multi-field spill outcome with a defined volume threshold and distinct sensitive-location and recovery fields. It is not the same construct as the shortlisted exploration-and-production or midstream records because the available source evidence does not establish either of those segment-specific boundaries.

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.

Method disclosures required

Source-edition basis: TNFD sector guidance, Final English sector guidance collection through August 2026 (17 documents).

  • Define the hydrocarbon-spill identification and measurement method.
  • State how the greater-than-1-barrel qualification threshold is applied.
  • Describe the criteria used to identify sensitive locations.
  • Describe the method used to determine recovered hydrocarbon volume.

Record-specific limitations

  • The 1-barrel threshold excludes smaller spills.
  • Sensitive-location treatment and recovery measurement methodology should be described to support comparability.

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.
