Dimensions and units
- Unit
- percent — source-defined reporting unit
- Reporting basis
- Reporting period covered by the Scope 3 inventory
Unit meaning: Values use percent under the disclosed Scope 3 method, period and boundary.
Table fields and units
- Scope 3 category
- Percentage of category emissions calculated using supplier or value-chain-partner data (%)
Published dimensions
- Scope 3 category
- Data source type: supplier or other value-chain partner

- Formula type
- Ratio
Formula
(Scope 3 category emissions calculated using supplier or value-chain-partner data / total Scope 3 emissions in the same category) × 100Apply the stated Scope 3 method only within the disclosed boundary and with compatible inputs. The standard explicitly requires this percentage to be reported for each Scope 3 category. It is a reportable category-level data-source-coverage outcome, distinct from the gross Scope 3 emissions total and from the shortlisted ESRS metric, which is an edition-specific single value limited to primary data obtained from suppliers.
Variables
| Symbol | Variable | Definition | Unit |
|---|---|---|---|
E_partner | Scope 3 category emissions calculated using supplier or value-chain-partner data | Emissions in the relevant Scope 3 category calculated using data from suppliers or other value-chain partners. | tCO2e |
E_category | Total Scope 3 category emissions | Total reported emissions in the same Scope 3 category. | tCO2e |

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: Corporate Value Chain (Scope 3) Accounting and Reporting Standard, 2011 publication.
- For each Scope 3 category, report the percentage of emissions calculated using data from suppliers or other value-chain partners.
Record-specific limitations
- The percentage is required for each Scope 3 category and should not be treated as a single consolidated Scope 3 percentage without category-level reporting.
- The source supports supplier and other value-chain-partner data as the numerator basis but does not specify a supplier-count, spend-coverage, or other non-emissions denominator.
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.
