Cameron targets ‘green coal’ goal
The coal either has its CO2 removed, or captured after burning, to prevent it ending up in the atmosphere.
The Tory leader said his government would ensure all coal-fired power stations would be fitted with developing “carbon capture” technology.
Speaking in China, Mr Cameron also said countries whose industry grew later had less responsibility on emissions.
Mr Cameron pledged that all new coal-fired stations in the UK would have to be built with carbon capture technology in place.
The idea is that the captured carbon dioxide is stored underground, possibly in empty oil and gas fields underneath the North Sea.
Ministers are currently conducting a competition among companies bidding for government grants to develop workable systems.
Norway is running a similar project with gas-fired power stations.
