Ah! "In any case it's quite clear that most of the major emitters - the USA, China and soon, other emerging mega-economies - have no intention whatsoever of cutting emissions. "
Doesn't matter, because the UK is going to slash its emissions so much that their cuts will make up for USA, China, India, and the rest of the world too!
Thanks for the vow of poverty, blokes! Enjoy your poverty with the clean conscience that can only come from using - sparingly - clean energy!
