The term carbon sequestration is used in different ways in the literature and media. The IPCC Sixth Assessment Report defines it as "The process of storing carbon in a carbon pool". Subsequently, a pool is defined as "a reservoir in the Earth system where elements, such as carbon and nitrogen, reside in various chemical forms for a period of time".
The United States Geological Survey (USGS) defines carbon sequestration as follows: "Carbon sequestration is the process of capturing and storing atmospheric carbon dioxide." Therefore, the difference between carbon sequestration and carbon capture and storage (CCS) is sometimes blurred in the media. The IPCC however defines CCS as "a process in which a relatively pure stream of carbon dioxide (CO) from industrial sources is separated, treated and transported to a long-term storage location".
Hence CCS is a technology application that utilizes artificial carbon sequestration techniques.
