Carbon sink 2026-11-05
A carbon sink takes up more carbon than it releases over a specified interval. It is a statement about a net transfer, whereas carbon storage describes an amount already held. If a reservoir's carbon stock is , its balance is
A positive balance makes it a carbon sink relative to the stated boundary. A large, nearly unchanged stock can provide substantial carbon storage without acting as a strong current carbon sink.
Forests acquire carbon through photosynthesis and lose it through cellular respiration, decay, fire and removal of biomass. Forest inventories and long-term ecosystem measurements therefore have to account for both accumulation and losses: the carbon sink in growing forests is not automatically the net effect of all changes in forested land.[ref]
