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.

- Eligible third-party certification systems included in the calculation.
- Treatment of forest area under ownership, lease and management arrangements.
- Basis for excluding Controlled Wood, SFI Fiber Sourcing and other ineligible designations.
- Reporting-period basis and any changes in managed forest area.
Record-specific limitations
- Only certification under eligible globally recognized third-party systems is included.
- The result depends on the organisation's definition and inventory of forest area under management.
- Lower-standard designations identified in the guidance are excluded.
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.
