MetricWater pollution

Water discharged per tonne of product output by water class

Measurement answer

What this metric measures

Reports water discharged per tonne of declared crop or product dry matter or animal protein, separately for total, freshwater and other water.

Specification

Result format
Structured table
Unit
Structured table with field-level units: discharge volume in m³; product-output denominator in tonnes; intensity in m³ per tonne — source-defined reporting unit
Reporting basis
Reporting period stated for the disclosure
Aggregation
Report total, freshwater and other-water results separately for each compatible product-output denominator; do not aggregate results across different denominator bases without disclosing the conversion or weighting method.

Reporting boundary

Water discharged within the reporting entity's declared operational and/or value-chain boundary, with the applicable crop, product dry matter or animal-protein output basis stated.

Disclosure form

No single formula

Report the source-defined result with its stated fields and method disclosures. The source specifies a separately reportable outcome with a m³-per-tonne intensity and required water-class differentiation. It is not the same construct as the existing TNFD wastewater discharge profile, which includes pollutant concentration, temperature and broader discharge-profile fields, and it is not equivalent to absolute water-discharge metrics. Because the source permits several denominator bases, publication as a structured disclosure preserves those variants rather than flattening them into one scalar intensity.

Verified sources

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.

Source-edition basis: TNFD sector guidance, Final English sector guidance collection through August 2026 (17 documents).

  • Official TNFD sector-guide metric code, guide title, version, table and page locator
  • Whether the metric is additional recommended or otherwise classified in the applicable sector guide
  • Reporting period and relevant production period
  • Declared operational and/or value-chain boundary and included facilities, activities and products
  • Water-class definitions used for total, freshwater and other water
  • Discharged-water measurement, estimation or calculation method
  • Product-output denominator definition, including whether crop dry matter, product dry matter or animal protein is used
  • Treatment of co-products, mixed production, allocation, exclusions and estimated data
  • Geographic scope and facility or production-location coverage

Record-specific limitations

  • The source permits alternative output denominators; m³ per tonne values based on crop dry matter, product dry matter and animal protein are not directly interchangeable.
  • The source extract does not prescribe a common water-quality threshold or destination classification for freshwater and other water.
  • Results depend on the declared reporting boundary, product-output basis, measurement method and treatment of mixed or multi-output production.

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.
