A carbon dioxide (CO2) sink is a carbon reservoir that is increasing in size, and is the opposite of a carbon "source".

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.

To help mitigate global warming, a variety of means of artificially capturing and storing carbon, as well as of enhancing natural sequestration processes, are being explored..
