Sir David King, UK Special Representative for Climate Change, spoke to the International Energy Authority this morning on what happens after COP21.
While recognising the large implementation challenges, as well as the huge risks of failing to contain warming, Sir David was very upbeat on the prospects for implementation. In particular he pointed to:
His conclusion was that the fall in clean energy prices and the roll-out of renewables generating capacity will both be much quicker than people expect. This could be the biggest commercial opportunity of our time.
In passing, he also noted that the 1.5 degree target requires no net emissions by 2035 and so is highly challenging.
