The costs of tackling climate change can be slashed if a network of pipes is built to store waste carbon dioxide under the North Sea, BBC informs.

The technology - carbon capture and storage – involves pumping CO2 emissions from power stations into rock formations.

It is expensive, but parliamentary advisors say the costs can be halved.

Savings can be achieved if the system to deliver the London Olympics is copied, they tell ministers.
The climate change minister Nick Hurd told BBC News he would welcome new ideas for promoting CCS.
Will carbon capture ever happen in the UK?

The technology is regarded by many experts as an essential weapon in the battle against climate change as it allows the use of fossil fuels to continue until electricity storage for renewables improves.

But last November the government scrapped an industry competition to promote it, citing the £1bn cost.

Now the Parliamentary Advisory Group on CCS says a CO2 pipeline network created by the equivalent of a stand-alone Olympic delivery agency would solve the problem.
