I am not surprised that the right hon. Gentleman makes such a profound point, given his experience. Whatever we do in the UK and however much we talk about our progress, it is an infinitesimal part of the current emissions profile.
Two things have happened since Paris. First, I know it sounds very boring and dull, but the development of a rule book, so that we can look each other in the eye and hold each other to account on an agreed set of measurements, is really important. If we cannot measure it, we cannot manage it. Secondly, the COP next year will be important because we will set out our nationally determined contributions and be able to quantify, on a like-for-like basis, what the current emissions profile looks like.
It is incredibly important that the COP is successful and ambitious, but we should not forget how seminal it was to get 196 countries even to agree on that target and to agree a process for working together; that is unprecedented. My hope is that the global protests and conversations will focus the minds of Ministers across the world and result in a successful outcome from the 2020 COP.
