The economic impact of fracking is a matter for the Department for Energy and Climate Change.
The paper that my Hon Friend refers to was an internal draft document. It was not analytically robust and was not signed off by Ministers. It has not been published and we have no plans to do so.
My department is responsible for the environmental aspects of this policy. The Royal Society and Royal Academy of Engineering review on shale gas concluded if fracking is properly regulated it is safe and has minimal environmental impacts.
