Carbon dioxide sink - From Wikipedia, the free encyclopedia - A carbon dioxide (CO2) sink is a carbon dioxide reservoir that is increasing in size, and is the opposite of a carbon dioxide source. The main natural sinks are (1) the oceans and (2) plants and other organisms that use photosynthesis to remove carbon from the atmosphere by incorporating it into biomass and release oxygen into the atmosphere. The process by which carbon dioxide sinks (natural and artificial) remove CO2 from the atmosphere is known as carbon sequestration. Public awareness of the significance of CO2 sinks has grown since passage of the Kyoto Protocol, which allows their use as a form of carbon offset.

Carbon dioxide sink - A carbon dioxide (CO2) sink is a carbon reservoir that is increasing in size, and is the opposite of a carbon. The main natural sinks are the oceans and plants and other organisms that use photosynthesis to remove carbon from the atmosphere by incorporating it into biomass. This concept of CO2 sinks has become more widely known because of its role in the Kyoto Protocol. Carbon sequestration is the term describing processes that remove carbon from the atmosphere.

A carbon dioxide sink or CO2 sink is a carbon reservoir that is increasing in size, and is the opposite of a carbon source. The main sinks are the oceans and growing vegetation. The concept has become more widely known through its application by the Kyoto Protocol. - Source
