Water replenished or restored in basins where water is withdrawn
Measurement answer
What this metric measures
Volume of water replenished or restored in the same basins from which the organization withdraws water, reported in cubic metres with basin-level correspondence and quantification basis disclosed.

Disclosure form
No single formulaReport the source-defined result with its stated fields and method disclosures. TNFD additional-sector metric B.C3.0 explicitly identifies a reportable volume outcome, specifies cubic metres, and limits the outcome to basins from which water is withdrawn. It is not the same construct as the existing water-replenished metric because the TNFD item requires withdrawal-basin correspondence rather than total programme replenishment and water-scarce-area reporting. A basin-level structured disclosure preserves that boundary without inventing a scalar aggregation or replenishment methodology.

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.

- Identify the basin used to establish correspondence between withdrawals and replenishment or restoration.
- Describe the method and evidence used to quantify replenished or restored water volumes.
- Disclose whether reported volumes are directly measured, modelled, estimated, or attributed through a programme or third party.
- Disclose the basis for any aggregation of basin-level volumes.
Record-specific limitations
- The cited specification does not prescribe a replenishment methodology, attribution method, verification approach, or treatment of volumes restored through third parties.
- Volumes must not be represented as replenishment for withdrawals occurring outside the reported basin.
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.
