Disclosure form
No single formulaReport the source-defined result with its stated fields and method disclosures. This is an additional Marine Transportation sector outcome metric with explicitly reportable count and fleet-share fields. It is not the same construct as general substances-of-concern or hazardous-waste metrics because its population is ships and its reported result is a fleet activity profile.

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).
- State the definition of the total fleet used as the percentage denominator.
- State the category assignment approach for ships transporting fossil fuels and bunkering, hazardous substances, and alternative fuels.
- State how ships associated with more than one reported category are treated.
Record-specific limitations
- The extracted specification does not define category-level thresholds, treatment of ships undertaking more than one category of activity, or whether leased, chartered, or managed vessels are included.
- The disclosed percentage is only comparable where the organization applies a consistent definition of its total fleet.
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.
