Formula
P = (Nq / Nd) × 100, where Nq is the number of qualifying hydrogen projects using desalinated water located within the defined proximity of an existing or planned desalination facility and Nd is the number of hydrogen projects using desalinated water.Apply the source-defined TNFD sector-guidance method within the stated reporting boundary. The source specifies a reportable count and proportion, a defined project population, and an explicit percentage denominator. The unspecified proximity threshold is retained as a required methodology disclosure rather than standardized or inferred.
Variables
| Symbol | Variable | Definition | Unit |
|---|---|---|---|
P | Qualifying-project percentage | Percentage of hydrogen projects using desalinated water that meet the defined desalination-facility proximity condition. | % |
Nq | Qualifying hydrogen projects | Number of hydrogen projects using desalinated water located within the defined proximity of an existing or planned desalination facility. | number of hydrogen projects |
Nd | Hydrogen projects using desalinated water | Denominator population of hydrogen projects using desalinated water. | number of hydrogen projects |

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.

- Define the proximity threshold and measurement approach used to determine whether a project is near a desalination facility.
- State the population of hydrogen projects using desalinated water used as the percentage denominator.
- State whether desalination facilities are existing, planned, or both, and how planned facilities are identified.
- Disclose treatment of projects with separate intake or brine-discharge infrastructure where relevant to interpretation.
Record-specific limitations
- The source does not prescribe a universal proximity threshold; reported results depend on the organization's disclosed definition of proximity.
- The metric indicates siting intended to avoid separate intake and brine-discharge infrastructure but does not itself demonstrate avoided impacts or infrastructure outcomes.
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.
