This is about not just actions, policies and words, but delivery. As others have noted, PricewaterhouseCoopers has said that the UK is at the top of the G20 leader board in this space.

That is important because the best way to cut emissions is to have recessions, which is not a good thing for the prosperity and the future of our constituents. It is extremely important therefore that we recognise and celebrate that progress, but that we commit ourselves to do more.
