Annual net land carbon stock change
Measurement answer
What this metric measures
Annual net change in land carbon stocks on lands from which the company sources biogenic CO2 or carbon, reported with land, carbon-pool, boundary and method context.

Disclosure form
No single formulaReport the source-defined result with its stated fields and method disclosures. Requirement 25 explicitly requires companies to quantify and report this annual outcome. It is a separately reportable land-carbon result, but the source does not prescribe one unit or a sufficiently uniform calculation basis for a scalar metric. A structured table preserves land, pool, boundary and method variants without treating it as land-use area, land-use-change area or a removals metric.

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.

- Land boundary and the linkage between each reported land area and sourced biogenic CO2 or carbon.
- Reporting-period start and end dates and the basis used to determine annual net change.
- Carbon pools included or excluded and the stock-change quantification method used.
- Data sources, spatial resolution, traceability level and material uncertainty assumptions.
- Treatment of land-use change, leakage and any separately reported emissions or removals so that they are not netted into the stock-change result.
Record-specific limitations
- The source requires reporting annual net change but does not prescribe a single unit, stock-accounting method, carbon-pool coverage or aggregation approach.
- The reported result is limited to lands sourcing biogenic CO2 or carbon and is not a general forestry metric or a measure of land-use-change emissions.
- Net land carbon stock change must not be combined with later removals, avoided emissions, GHG credits or credit-adjusted inventory values.
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.
