Structured Disclosure

Disclosure form

No single formula

Report the source-defined result with its stated fields and method disclosures. Section 13.3.5 explicitly permits disaggregation of emissions by specific processes or inputs. This is a reportable product-inventory result when expressed within the declared product boundary and per declared unit of analysis; it is not a corporate Scope 1, 2 or 3 metric.

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: Product Life Cycle Accounting and Reporting Standard, September 2011 publication.

  • Declare the product and unit of analysis, including the functional unit or reference flow where applicable.
  • Identify each disclosed process or input category and the life-cycle stage to which it relates.
  • Disclose the product inventory boundary and boundary type.
  • Disclose the GWP source and date used for CO2e characterization.
  • Disclose applicable allocation, recycling and land-use-change methods.
  • State whether rows are mutually exclusive and whether they reconcile to the reported product inventory total.

Record-specific limitations

  • This is an optional disaggregation of the product inventory result and does not replace the required net total in CO2e per unit of analysis.
  • Rows must not be summed where process or input categories overlap.
  • Offsets, avoided emissions, delayed-emission weighting, indirect land-use change and indirect market effects must not be netted into the reported inventory impacts.

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.
