Carbon capture and storage is essential for a sustainable energy future in a world that faces constraints on the use of carbon but remains - for the foreseeable future - reliant on fossil fuels. CCS has the potential to make a quarter of the emissions reductions required to stabilise the atmospheric concentration of CO2 at 550 parts per million (ppm) and limit temperatures rises to 2ºC above pre-industrial levels.
Encouragingly, the technologies involved in CCS have been proved independently and capital is available. The big test facing governments is to create a policy environment that will allow companies to put these technologies together safely, at a reasonable cost and on a big enough scale to make a meaningful dent in global CO2 emissions.
