Circular sourcing composition

Measurement answer

What this metric measures

Reports the weight and percentage of physical products classified into specified circular sourcing categories, including non-virgin materials, by-products or waste streams, regeneratively produced renewable materials, sustainably produced renewable materials, and products not meeting those categories.

Specification

Result format
Structured table
Unit
tonnes; % — source-defined reporting unit

Value structure

Dimensions and units

Unit
tonnes; % — source-defined reporting unit
Reporting basis
Reporting period stated by the reporting organization.

Unit meaning: Values use tonnes; % under the disclosed TNFD sector-guidance method, reporting period and boundary.

Disclosure form

No single formula

Report the source-defined result with its stated fields and method disclosures. AT.A23.0 requires a separately reportable category-disaggregated outcome containing both physical-product weight and proportion. It is not the same construct as a single circular-material-use rate because it preserves multiple sourcing categories, a weight field and category-specific classification 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.

Interpretation boundaries

Method disclosures required

Source-edition basis: TNFD sector guidance, Final English sector guidance collection through August 2026 (17 documents).

  • Definitions and eligibility criteria used for each circular sourcing category.
  • Whether categories are mutually exclusive and collectively exhaustive, and treatment of products containing multiple material types or sourcing attributes.
  • Physical-product weight basis, including treatment of components, packaging, intermediate products and excluded products.
  • Denominator used for each percentage and reconciliation of category weights to total covered physical-product weight.
  • Organizational, product and value-chain coverage, reporting period, data sources and estimation approach.

Record-specific limitations

  • Category results depend on the organization's disclosed classification of inputs and products as non-virgin, by-product or waste-stream, regeneratively produced renewable, sustainably produced renewable, or not meeting these categories.
  • The source does not establish a universal product-coverage boundary or prescribe classification evidence; these must be disclosed by the reporting organization.
  • Percentages are meaningful only where the denominator of covered physical-product weight is consistently defined across categories.

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.
