A. Sinks in the land sector The forest contributes to the underlying SNBC scenario (AMS scenario) as a carbon sink in the forest ecosystem, as a carbon sink in wood products, and through substitution effects through the production of materials and energy that can substitute for more GHG-emitting materials and energy.
