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.

- Organizational and operational boundary
- Consolidation approach and base year
- Reporting period and recalculation policy
- Included gases and GWP source
- Data sources, methods, uncertainty and verification
- Exclusions, offsets and removals treatment
Record-specific limitations
- Combine only non-overlapping observations with compatible organizational boundaries, consolidation methods, periods, gases and GWP bases.
- Gross emissions remain separate from removals, offsets, allowances and target-compliance trades.
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.
