Value structure
Dimensions and units
- Unit
- km² — source-defined reporting unit
- Reporting basis
- Reporting period
Unit meaning: Values use km² under the disclosed TNFD sector-guidance method, reporting period and boundary.
Published dimensions
- value designation (high biodiversity value or high conservation value)
- protection basis (formal or effective protection)
- geographic location

Formula
A_protected = Σ A_i for each non-duplicative area i identified as high biodiversity value or high conservation value and under formal or effective protection.Apply the source-defined TNFD sector-guidance method within the stated reporting boundary. The source specifies a standalone, quantitatively reportable area metric with an explicit km² unit and a defined qualification condition. It is distinct from disclosures of site proximity to sensitive areas or site-level biodiversity attributes.
Variables
| Symbol | Variable | Definition | Unit |
|---|---|---|---|
A_protected | Protected qualifying area | Total non-duplicative area of land identified as high biodiversity value or high conservation value that is under formal or effective protection. | km² |
A_i | Qualifying protected area | Individual non-overlapping land area meeting the value and protection criteria. | km² |

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).
- Define the criteria and data sources used to identify high biodiversity value and high conservation value land.
- Describe the basis for classifying protection as formal or effective.
- State the geographic and organisational boundary, assessment date and treatment of overlapping protected areas or overlapping value designations.
Record-specific limitations
- The evidence does not prescribe a single taxonomy, threshold or assessment method for identifying high biodiversity value or high conservation value.
- Formal protection and effective protection may use different legal, governance or management bases and should not be conflated without disclosure.
- The metric reports protected qualifying area; it does not establish biodiversity condition, conservation outcomes or protection effectiveness.
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.
