Feed ingredient eutrophication potential by water type
Measurement answer
What this metric measures
Eutrophication potential of each original raw material used in feed, reported in kilograms of phosphorus equivalent per tonne of ingredient and differentiated by freshwater, marine-water and brackish-water pollution.

Formula
Eutrophication potential attributable to an original feed raw material for a specified receiving-water type / Mass of that raw materialApply the source-defined TNFD sector-guidance method within the stated reporting boundary. A.C2.1 specifies a reportable ingredient-level environmental intensity with a defined unit and mandatory receiving-water dimensions. It is not equivalent to water-policy, water-target, marine financial-effect, or ballast-water metrics in the shortlist.
Variables
| Symbol | Variable | Definition | Unit |
|---|---|---|---|
EP_i,w | Eutrophication potential for ingredient and water type | Eutrophication potential attributed to original feed raw material i for receiving-water type w, expressed in phosphorus equivalents. | kg P-Eq |
M_i | Mass of ingredient | Mass of original feed raw material i used as the denominator for the reported intensity. | t of ingredient |

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.

- Eutrophication-potential methodology and characterization factors used.
- Original feed raw materials included and the basis for assigning raw-material quantities.
- Receiving-water classification used for freshwater, marine-water and brackish-water results.
- Data sources, allocation choices and other material assumptions used to derive ingredient-level values.
- Any use of GSI/WWF guidance or other cited methodology, including version and deviations.
Record-specific limitations
- The metric is an impact-potential intensity and does not directly measure observed pollutant concentrations or ecological condition in receiving waters.
- Results depend on the eutrophication characterization methodology and source data used for each raw material.
- The source specifies differentiation by water type; combining water-type results without a disclosed method would obscure the required distinction.
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.
