Formula
P_r = (R_indigenous,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.A1.1 specifies a standalone, reportable two-field percentage outcome with separate proved-reserve and probable-reserve results. No shortlist entry represents the same reserve-location construct and two-class output.
Variables
| Symbol | Variable | Definition | Unit |
|---|---|---|---|
P_r | Percentage of reserves in or near Indigenous territories for reserve class r | Reported percentage for the relevant reserve classification. | % |
R_indigenous,r | Reserves in or near Indigenous territories for reserve class r | Amount of reserves in the relevant reserve classification located in or near Indigenous territories. | 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_indigenous,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 geographic data source and method used to identify Indigenous territories.
- Define and disclose the criterion used to determine whether a reserve is 'in or near' an Indigenous territory.
- State the denominator for each reserve-class percentage and 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' Indigenous territories.
- The extracted evidence does not specify the geographic source, legal recognition basis, or mapping methodology for Indigenous territory boundaries.
- Percentages for proved and probable reserves are distinct fields and must not be combined unless a separate, disclosed reserve-class aggregation method is used.
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.
