Chemical pollutants released to the ocean from direct operations
Measurement answer
What this metric measures

Formula
Total chemical pollutants released to the ocean = sum of tonnes released to the ocean for each reported pollutant type.Apply the source-defined TNFD sector-guidance method within the stated reporting boundary. The source specifies a reportable outcome quantity, unit, receiving environment, direct-operations boundary and required pollutant-type disaggregation. It is distinct from investor-weighted pollutant intensities and broad all-media pollution disclosures in the shortlist.
Variables
| Symbol | Variable | Definition | Unit |
|---|---|---|---|
Q_p | Chemical pollutant release by pollutant type | Tonnes of a specified chemical pollutant released to the ocean from direct operations during the reporting period. | tonnes |
Q_total | Total chemical pollutants released to the ocean | Sum of reported chemical pollutant releases to the ocean across pollutant types. | 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.

Method disclosures required
Source-edition basis: TNFD sector guidance, Final English sector guidance collection through August 2026 (17 documents).
- Identify the pollutant types included in the reported total.
- Report the tonnes released for each pollutant type and the total tonnes released.
- State the direct-operations boundary used for the disclosure.
- Describe the method, data sources and assumptions used to quantify releases to the ocean.
- Retain TNFD source attribution; referenced ASC Farm Standard material and scientific literature remain separately attributed and are not implied to share TNFD's CC BY 4.0 licence.
Record-specific limitations
- The extracted evidence requires pollutant-type disaggregation but does not specify a complete pollutant inventory, measurement method, release pathway definition, or organisational-control methodology.
- Copper is explicitly identified as an included pollutant type; the evidence does not establish that copper is the only required pollutant-specific field.
- The metric concerns releases to the ocean and must not be treated as an all-media pollutant-emissions metric.
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.
