Scenario Lab arithmetic
Hectares × editable assumption = result.
Method
Loss: lost ha = mapped ha in scope × loss %. Carbon released = lost ha × stock density (tC/ha). CO₂e = tC × 44/12.
Restoration: captured tCO₂e = ha × survival × annual rate × years.
Default brackets (low / central / high) are illustrative and clearly labelled; users can overwrite them.
Limits. No dynamics, no uncertainty propagation, no leakage or permanence adjustments.
