Formula
N = count of fishing gear items lost at sea during the annual reporting period, reported by gear type.Apply the source-defined TNFD sector-guidance method within the stated reporting boundary. Published because the sector guidance explicitly requires annual data on fishing gear lost at sea, including both the number of lost items and gear type. This is an independently reportable environmental outcome count, rather than a calculation input or methodological parameter.

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 period used for the annual count.
- Disclose the gear types represented in the count.
- Describe the organisational and activity boundary used to identify fishing gear items lost at sea.
- State how lost gear items are identified and counted where this affects interpretation of the reported total.
Record-specific limitations
- The metric counts lost gear items and does not, on its own, measure gear mass, retrieval, recovery, destination, ecological impact, or the extent of ghost fishing.
- Comparability depends on consistent identification and categorisation of gear types.
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.
