Mr. Marc Kierans:

I thank the Deputy. One point to stress on this is that the GWP100 is the default emission used in the international process. I accept the Deputy's point. On what the Department has done and continues to do, the Department has worked within the UN international process and the EU process at various levels. It has engaged with the likes of Professor Allen to understand this process and has put forward in those negotiations on the changes. It is a slow, tortuous process, as Professor Thorne pointed out, but we do work towards that. It is just that it takes time and the science has to be settled. It is, necessarily, a very rigorous process to adopt new changes to the UN inventory figures.
