GHG Removal and Storage

Definition

GHG Removal and Storage . (Anthropogenic) Removals refer to the withdrawal of GHGs from the atmosphere as a result of deliberate human activities. These include enhancing biological sinks of CO2 and using Chemical engineering to achieve long-term removal and storage. Carbon capture and storage (CCS) from industrial and energy-related sources, which alone does not remove CO2 in the atmosphere, can reduce atmospheric CO2 if it is combined with bioenergy production (BECCS). Removals can be subject to reversals, which are any movement of stored GHG out of the intended storage that re- enters the surface and atmosphere. For example, if a forest that was grown to remove a specific amount of CO2 is subject to a wildfire, the emissions captured in the trees are reversed.
