Supply chain sourcing area with native vegetation
Measurement answer
What this metric measures
Reports the percentage of supply-chain sourcing area that maintains native vegetation, with explicit treatment of sourcing areas from ecologically sensitive locations.

Formula
Supply-chain sourcing area with native vegetation (%) = (sourcing area with native vegetation / supply-chain sourcing area from sensitive locations) × 100.Apply the source-defined TNFD sector-guidance method within the stated reporting boundary. The candidate describes a directly reportable area-based percentage outcome rather than a method input. The retained denominator reflects the extracted specification and avoids broadening the measure to all supply-chain area without evidence. No shortlist entry matches this nature-specific area percentage.
Variables
| Symbol | Variable | Definition | Unit |
|---|---|---|---|
N | Sourcing area with native vegetation | Supply-chain sourcing area identified as maintaining native vegetation. | area |
A | Supply-chain sourcing area from sensitive locations | Supply-chain sourcing area in the reported denominator, particularly sourcing areas from ecologically sensitive locations. | area |

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 native vegetation used for the calculation.
- Define the sourcing-area boundary and the identification method for ecologically sensitive locations.
- State the area measurement method and denominator used for the percentage.
- Disclose whether the result covers all sourcing areas or only sourcing areas from sensitive locations.
Record-specific limitations
- Comparability depends on the organization's definition and mapping of sourcing areas, sensitive locations, and native vegetation.
- The evidence emphasizes ecologically sensitive locations; disclosures should distinguish results where the reported denominator is limited to those locations.
- The metric is an area-based condition measure and does not by itself establish vegetation quality, biodiversity condition, or causation by the reporting organization.
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.
