Doha: Carbon deal could add hundreds of pounds to energy bills There are already disagreements between the Treasury and the Department of Energy and Climate Change over the existing 34 per cent target. George Osborne, the Chancellor, has insisted it should be reviewed in 2014. The deal on the table in Doha would commit the EU to a second period of the Kyoto Protocol, agreeing to consider upping its target for cutting emissions. If this happens, and the EU goes from 20 to 30 per cent, the Government has said it will consider moving to 42 per cent. Peter Lilley, the Tory MP, said Britain was already struggling with targets and pointed out that the world's two largest carbon emitters, the US and China, were not even in the protocol. I think it's most self-flagellating to sign Britain up to be bound by such targets when the bulk of the world is not. At a time when our main objective is to rebalance the economy, to put burdens on our manufacturing sector is self-defeating," he said. However Ed Davey, the Energy and Climate Change Secretary, who is leading the UK delegation, supports a move to 30 per cent by the EU, which it will only do if the US and China also commit to action. The Doha talks should progress towards a global deal by 2015 that will commit the whole world to cutting emissions, but environmentalists, charities and scientists are disappointed that the pledges are not tough enough. "The climate system will not wait decades for the governments of the world to inch towards an agreement," said Prof Sir Brian Hoskins, director of the Grantham Institute for Climate Change at Imperial College London.
