Carbon Sink

A carbon sink is a reservoir that store carbon containing compounds like carbon dioxide for an indefinite period thereby offsetting carbon emissions. There are two types of carbon sinks-natural and artificial. Artificial sinks are those created by man to capture and store carbon dioxide to prevent the accumulation of the same in the environment. Examples of artificial carbon sinks are underground geological formations like depleted oil and gas fields, coal bed methane and saline aquifers, while terrestrial plants and trees that absorb CO2 through the process of photosynthesis is a perfect example for natural carbon sinks.
