Formula
C = count of vessel collisions with marine animals during the reporting periodApply the source-defined TNFD sector-guidance method within the stated reporting boundary. This is an explicitly specified TNFD additional sector outcome metric: a reportable collision count with required species and location disaggregation. It is not equivalent to marine casualties, port calls, vessel capacity or air-emissions metrics in the shortlist.

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.

- Describe the vessel-operation boundary included in the count.
- Describe the incident-identification and collision-reporting method.
- State how marine animal species are identified or recorded, including treatment of unidentified animals.
- Provide the geographic-location method and GPS-coordinate precision or format used.
Record-specific limitations
- The reported count depends on collision detection, incident reporting and the ability to identify the animal species.
- Species identification and location data may be incomplete where a collision is not observed or verified.
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.
