Characteristics of new or upgraded linear infrastructure in sensitive and other areas
Measurement answer
What this metric measures
Discloses characteristics of new or upgraded linear infrastructure that may contribute to fragmentation, differentiated between sensitive locations and other areas, including infrastructure extent, design, planned use, mitigation structures and evidence of wildlife use.
Specification

- Result format
- Structured table
- Unit
- Structured table — see field-level units
- Reporting basis
- Reporting period used for the disclosure; the extracted source does not prescribe a distinct time basis.
- Aggregation
- Report separately for sensitive locations, identified by disclosed sensitivity criteria and ecosystem type, and for other areas, identified by ecosystem type; report wildlife crossings and mitigation measures per kilometre of relevant linear infrastructure.
- Pillar
- Environmental
- Topic
- Nature-related impacts from linear infrastructure fragmentation
- Controlled domain
- Nature, biodiversity and land
- Entity type
- Metric
Reporting boundary
New or upgraded linear infrastructure covered by the reporting entity's disclosed project, operational and value-chain boundary; the extracted source requires location differentiation but does not prescribe an organizational or value-chain boundary.

Disclosure form
No single formulaReport the source-defined result with its stated fields and method disclosures. CM.C1.0 explicitly calls for disclosure of a multi-field set of characteristics for new or upgraded linear infrastructure, with location and ecosystem differentiation and mitigation information. This is a standalone structured reporting outcome rather than a calculation input or a duplicate of land-use change or infrastructure expenditure metrics. The source specifies some field-level units but does not prescribe a single common unit, so the canonical metric is retained as a structured table with field-level units and explicit method disclosures.
Verified sources
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 used to classify a location as sensitive and identify the ecosystem-type classification applied.
- State whether each asset is new construction or an upgrade and describe the project, operational and value-chain boundary covered.
- Describe how infrastructure length and footprint were measured, including treatment of associated facilities and route segmentation.
- State the unit, estimation method, scenario or forecast basis, and reference date for planned traffic volume.
- Describe material or surface-type classification.
- Define crossing structures and other mitigation measures included in the count, and state the relevant infrastructure length used as the denominator for measures per kilometre.
- Describe the method, period, evidence threshold and verifier, if any, used to determine verified wildlife use.
- State units, measurement method and coverage for structural dimensions of crossings or mitigation measures.
- Disclose data gaps, estimates, exclusions and changes in classification or methodology from the prior reporting period.
Record-specific limitations
- The disclosure is a characteristics-based proxy for fragmentation pressure and does not itself quantify ecological fragmentation or biodiversity outcome.
- The source does not prescribe a unit for planned traffic volume, material type, verified wildlife use, or structural dimensions; reporters must state the units, measurement basis and data source used.
- Comparability depends on consistent definitions of sensitive locations, ecosystem types, linear-infrastructure extent and wildlife-use verification.
- The extracted source does not specify organizational, value-chain or geographic consolidation rules; these must be disclosed.
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.
