Percentage

Formula

(W_scarcity / W_total) × 100

Apply the source-defined TNFD sector-guidance method within the stated reporting boundary. This is a standalone, reportable percentage with an explicit numerator, denominator and unit. It is distinct from the underlying structured C3.0 withdrawal-and-consumption disclosure because it expresses the scarcity-area withdrawal subset relative to total withdrawal.

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 and data source used to identify areas of water scarcity.
  • Whether the numerator and denominator use the same organisational water-withdrawal boundary.
  • Any exclusions from total water withdrawn.

Record-specific limitations

  • The metric is encouraged as supplementary reporting in sector guidance rather than identified in the evidence as a separate core TNFD metric.
  • The extracted evidence does not specify a sector-specific method for identifying areas of water scarcity.

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.
