Formula
P_r = (R_sensitive,r / R_total,r) × 100, reported separately for r = proved and r = probable reserves.Apply the source-defined TNFD sector-guidance method within the stated reporting boundary. OG.A1.2 is a distinct, reportable reserve-exposure percentage metric. The shortlist item for sites near biodiversity-sensitive areas is site-based rather than reserve-based, and therefore differs in population, denominator, aggregation, and value shape.
Variables
| Symbol | Variable | Definition | Unit |
|---|---|---|---|
P_r | Percentage of reserves in sensitive locations for reserve class r | Reported percentage for the relevant reserve classification. | % |
R_sensitive,r | Reserves in or near sensitive locations for reserve class r | Amount of reserves in the relevant reserve classification located in or near protected conservation areas or endangered species habitat. | same unit as R_total,r |
R_total,r | Total reserves for reserve class r | Total amount of reserves in the relevant reserve classification within the stated reporting boundary. | same unit as R_sensitive,r |

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 reserve classification methodology used for proved and probable reserves.
- Disclose the geospatial data sources and classification method used for protected conservation areas and endangered species habitat.
- Define and disclose the criterion used to determine whether a reserve is 'in or near' a sensitive location.
- State the denominator for each reserve-class percentage and identify any exclusions from the reserve population.
Record-specific limitations
- The extracted evidence does not define the distance or other threshold for determining whether reserves are 'near' a sensitive location.
- The extracted evidence does not define the protected-conservation-status taxonomy or the endangered-species-habitat data source.
- Percentages for proved and probable reserves are separate output fields and should not be collapsed into one percentage without a separately disclosed aggregation method.
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.
