Carbon capture and storage (CCS)
Mather, T. A.
As part of the government’s global strategy to address\ud climate change, the 2003 Energy White Paper sets the\ud target of a 60% reduction in UK emissions of the\ud greenhouse gas carbon dioxide (CO2) by 2050, to about\ud 240Mt (million tonnes) per year from 550Mt in 2000.1\ud Increased energy efficiency and use of renewable\ud energy are the key mechanisms proposed to achieve\ud this. However the White Paper suggests the continuing\ud importance of fossil fuels to ensure security of electricity\ud supplies. Using fossil fuels in a low-carbon economy\ud requires their CO2 emissions be reduced. This POSTnote\ud discusses the potential of carbon capture and storage\ud (CCS), a method of carbon sequestration2, to reduce UK\ud and global emissions, and also the costs, environmental\ud impacts and public perceptions of CCS.
