Circularity of material use
Measurement answer
What this metric measures
Separate proportions for regeneratively produced material inflows, recycled or reused input materials, and material, products or components/systems reused, repurposed or remanufactured from identified sources.
Specification
Metric specification
- Result format
- Structured table
- Unit
- % — source-defined reporting unit
- Reporting basis
- Reporting period for material inflows, products, components or systems assessed; no further period convention is specified in the extracted evidence.
- Aggregation
- Report each of the three proportions separately; do not combine them into a composite circularity rate.
- Pillar
- Environmental
- Topic
- Changes to nature: mitigation hierarchy steps
- Controlled domain
- Materials, circularity and waste
- Entity type
- Metric
Reporting boundary
Material inflows and total material mass, products, components or systems within the reporting organization's stated assessment scope; the extracted evidence does not further specify organizational or value-chain boundary.

Value structure
Dimensions and units
- Unit
- % — source-defined reporting unit
- Reporting basis
- Reporting period for material inflows, products, components or systems assessed; no further period convention is specified in the extracted evidence.
Unit meaning: Values use % under the disclosed TNFD sector-guidance method, reporting period and boundary.

- Major material type for recycled-or-reused input materials
- Source of reused, repurposed or remanufactured material: on-site demolition, refurbishment, or external sources

Disclosure form
No single formulaReport the source-defined result with its stated fields and method disclosures. The source explicitly specifies three distinct proportional measures rather than one circular-material-use rate. A structured family preserves their separate numerator, denominator, material-type and source dimensions and avoids flattening unlike constructs into a single percentage.

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.

- Definitions and eligibility criteria for regeneratively produced, recycled, reused, repurposed and remanufactured materials.
- Measurement method and denominator used for each of the three proportions.
- Major material-type categorization used for the recycled-or-reused input-material measure.
- Source classification method for material from on-site demolition, refurbishment and external sources.
- Reporting boundary and period applied.
Record-specific limitations
- The three reported proportions have different populations and denominators and are not additive.
- The extracted evidence does not define regenerative production, recycled material, reused material, repurposed material, or remanufactured material.
- The extracted evidence does not prescribe a common mass, product-count, or component-system denominator for all three measures.
- Organizational consolidation and value-chain coverage are not specified in the extracted evidence.
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.
