Formula
R = weight of antifouling paint particles released from the fleet during the reporting period.Apply the source-defined TNFD sector-guidance method within the stated reporting boundary. This is a standalone fleet-level pollution outcome with an explicit mass unit. It is narrower than the shortlisted ESRS microplastics-generated metrics because it is specifically limited to antifouling paint particles released from a fleet, and it does not establish a separate heavy-metals result.

R | Antifouling paint particles released from the fleet | Total reported weight of antifouling paint particles released from the defined fleet boundary. | tonnes |

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.

- Fleet scope, including owned, chartered, managed, or otherwise included vessels.
- Method used to measure or estimate antifouling paint particle releases.
- Antifouling paint types and relevant composition assumptions included in the calculation.
- Geographic and operational coverage of vessel activity.
- Treatment of maintenance, repainting, hull cleaning, and other relevant release events.
Record-specific limitations
- The extracted specification provides a weight of antifouling paint particles but does not provide a separate heavy-metal quantity.
- The extracted text does not prescribe a release-estimation method, paint composition threshold, vessel scope, or geographic release boundary.
- The result should not be represented as an independently measured microplastic-only or heavy-metal-only quantity unless supported by the disclosed method.
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.
