Circularity: use phase
Measurement answer
What this metric measures
Weight and proportion of physical products designed following use-phase circular-economy principles.
Specification
Metric specification
- Result format
- Structured table
- Unit
- tonnes; % — source-defined reporting unit
- Reporting basis
- Reporting period used for the product-design assessment; no further period convention is specified in the extracted evidence.
- Aggregation
- Report physical-product weight and the corresponding proportion of total products together; do not treat the weight and percentage as additive measures.
- Pillar
- Environmental
- Topic
- Changes to nature: mitigation hierarchy steps
- Controlled domain
- Materials, circularity and waste
- Entity type
- Metric
Reporting boundary
Physical products assessed as designed following use-phase circular-economy principles within the reporting organization's stated product scope; the extracted evidence does not further specify organizational or value-chain boundary.

Value structure
Dimensions and units
- Unit
- tonnes; % — source-defined reporting unit
- Reporting basis
- Reporting period used for the product-design assessment; no further period convention is specified in the extracted evidence.
Unit meaning: Values use tonnes; % under the disclosed TNFD sector-guidance method, reporting period and boundary.
Table fields and units
- Product group or category
- Qualifying use-phase circularity design criteria
- Weight of qualifying physical products (tonnes)
- Total-product denominator basis
- Proportion of total products (%)
- Reporting boundary and period
Published dimensions
- Result type: product weight or proportion of total products
- Product design status: designed following use-phase circular-economy principles
- Product group or category, where used by the reporting organization

Formula
(Weight or other stated denominator-basis amount of physical products designed following use-phase circular-economy principles / Total physical products on the same stated denominator basis) × 100Apply the source-defined TNFD sector-guidance method within the stated reporting boundary. The source identifies reportable physical-product weight and proportional outcomes for a defined design characteristic. It differs from generic circular-design profiles because it specifically concerns use-phase circularity and explicitly requires both tonnes and percentage reporting.
Variables
| Symbol | Variable | Definition | Unit |
|---|---|---|---|
Q | Qualifying products | Weight or other stated denominator-basis amount of physical products designed following the reporting organization's qualifying use-phase circular-economy principles. | tonnes or stated product denominator unit |
T | Total products | Total physical products included in the same reporting boundary and denominator basis. | tonnes or stated product denominator unit |

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.

- Use-phase circular-economy design principles and qualifying product-design criteria.
- Method used to determine the weight of qualifying physical products.
- Denominator basis used for the reported proportion of total products.
- Product categories included and excluded.
- Reporting boundary and period applied.
Record-specific limitations
- The extracted evidence does not define the use-phase circular-economy principles or qualifying design criteria.
- The extracted evidence does not specify whether the product denominator is weight, units, or another product basis for the percentage.
- The extracted evidence does not prescribe organizational consolidation, product lifecycle boundary, or value-chain coverage.
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.
