In this section, you will learn about the two types of sequestration:

• Geological sequestration – the separation and capture of CO₂ at the point of emissions followed by storage in deep underground geologic formations (also known as carbon capture and storage or CCS)
• Biological / terrestrial sequestration – the net removal of CO₂ from the atmosphere by plants and micro-organisms and its storage in vegetative biomass (biological) and in soils (terrestrial)

Carbon sequestration is the process by which natural and artificial carbon dioxide sinks remove CO₂ from the atmosphere that would otherwise persist for a long time.
