Is a fracking revolution the way to cut UK carbon emissions?

Labour shadow energy minister, Bryony Worthington has said that environmentalists should not take a blanket position against shale gas

This week, Labour shadow energy minister and environmentalist Bryony Worthington dismayed green groups by backing fracking as a way to reduce carbon emissions.

Following a speech on the Energy Bill in the House of Lords on Wednesday, Baroness Worthington told the Today Programme: "There are legitimate concerns, absolutely correct, that we need to do this safely, but we shouldn't take an in-principle objection to the technology and nor should we do that for any other of the low carbon technologies. Because [climate change] is the big challenge we face." She said that the "common enemy" is very cheap coal which entails much higher carbon emissions.
