Carbon dioxide (CO2) capture and sequestration (CCS) is a set of technologies that can greatly reduce CO2 emissions from new and existing coal- and gas-fired power plants and large industrial sources. CCS is a three-step process that includes:
Capture of CO2 from power plants or industrial processes
Transport of the captured and compressed CO2 (usually in pipelines).
Underground injection and geologic sequestration (also referred to as storage) of the CO2 into deep underground rock formations. These formations are often a mile or more beneath the surface and consist of porous rock that holds the CO2. Overlying these formations are impermeable, non-porous layers of rock that trap the CO2 and prevent it from migrating upward.
The figure below illustrates the general CCS process and shows a typical depth at which CO2 would be injected. Watch the following videos to learn more about how CCS works:

Tropical forests now emit more carbon than they are able to absorb from the atmosphere as a result of the dual effects of deforestation and land degradation, a new study says.
The research challenges the long-held belief that forests act as “carbon sinks” by storing more carbon than they emit due to natural processes and human activity.
