Carbon capture and storage / sequestration (CCS)

Carbon capture and storage/sequestration. A process involving the removal of carbon dioxide (CO2) from the atmosphere or the capture of anthropogenic (i.e. human induced) CO2 emissions from large-scale stationary sources before they are released to the atmosphere, and their long-term storage in reservoirs (under ground, under the ocean or through reforestation) using a set of technologies. CCS helps mitigate global warming and avoid the adverse impacts of climate change. It has been proposed as a way to slow down the accumulation of greenhouse gases in marine environments and in the atmosphere. By using CCS technologies emissions from e.g. new and existing coal- and gas-fired power plants and large industrial sources can be removed.
