The European Commission launched public consultations on potential risks from the new carbon capture and storage technology (CCST) developed to counter global warming. The technology separates carbon dioxide from gases produced by power plants, compresses the CO2 and transports it for storage in geological formations such as oil and gas fields. CCST could remove 80 to 90 per cent of power plants' CO2 emissions and reduce costs of stabilising CO2 concentrations in the atmosphere by 30 per cent. The consultations aim to examine environmental risks associated with the capture, transportation and storage of CO2 emissions. Interested parties are invited to comment by 16 April 2007.
