The practice of capturing CO2 emissions - typically from coal-fired power plants - and sequestering it in geological formations such as depleted oil and gas fields.
The technology is yet to be successfully demonstrated at large scale power plants, and critics maintain that there are concerns about the high cost of CCS and the risks associated with the stored carbon leaking back into the atmosphere.
