  • material or discharge type
  • spill classification scheme and classification
  • affected ecosystem type
  • applicable standard adhered to
  • volume (m³)

Sum

Formula

For each material or discharge type, spill classification and affected ecosystem, report the sum of volumes for spills and wastewater discharges exceeding the applicable local regulatory or international standard.

Apply the source-defined TNFD sector-guidance method within the stated reporting boundary. The candidate provides a directly reportable quantitative outcome with an explicit cubic-metre unit, qualifying threshold, required disaggregation and affected-ecosystem dimension. It must remain distinct from Fishing oil and fuel-waste spills because the population, qualification test, material scope and required ecosystem/classification dimensions differ. None of the shortlisted metrics has the same scope, threshold and dimensional requirements.

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.

Interpretation boundaries

Method disclosures required

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

  • Identify the local regulatory or international standard used to determine whether each spill or discharge exceeds the applicable threshold.
  • Identify the national or company spill classification scheme used, where applicable.
  • Disclose the type of ecosystem affected for each reported classification.
  • State the measurement basis used to quantify reported volumes in cubic metres.

Record-specific limitations

  • Only spills and wastewater discharges exceeding applicable local regulatory or international standards are within scope.
  • The applicable classification scheme may differ by jurisdiction or company and must be identified by the reporting organization.
  • The source does not provide a single universal threshold or a prescribed ecosystem taxonomy.

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.
