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.

  • Product and inventory version
  • Unit of analysis and reference flow
  • Boundary, exclusions and life-cycle-stage definitions
  • GWP source/date and included gases including the 2013 NF3 overlay
  • Allocation, recycling, land-use-change, uncertainty and assurance methods when applicable

Record-specific limitations

  • Product results are not corporate Scope 1, Scope 2 or Scope 3 inventories.
  • Offsets, avoided emissions, delayed-emission weighting and indirect effects are excluded from the inventory result.

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.
