 What has been achieved in Paris has been an enormous achievement. We would not have had this agreement without the efforts of everybody. I've never seen a mass movement of this magnitude. But Paris has only bent the four degree curve to about 2.7 degrees. There is no real commitment yet and follow-up and yet we're well on the way in terms of burning up our carbon budget, which is 1 trillion tons. What we need actually is maximum peaking in 2020 and net zero by 2050.
