I knew I could trust David Cameron's rhetoric about a green economy about as far as I can throw a steam roller. Sure enough, The Guardian has revealed that the UK's level of investment in green technology has slipped to 13th place behind Brazil (6th), India (10th) and China (1st). Unsurprisingly, part of the problem seems to be the continuing rift between the Department of Energy and Climate Change and the Treasury. As if it was ever going to be any different. You would think, with rising oil prices, that the government would want to stand by its green promises, especially with the opportunities that a green economy would bring in terms of sustainable growth and jobs. Those jobs however are going elsewhere and the UK will be all the poorer for it.
