Thank you very much.
There are lots of elements to your question, but let me take the last part. The current government's target, which as you say is a 20% reduction by 2020 based on 2006 levels, translates into roughly a 2% to 3% increase from 1990 levels. That is not even what we proposed to do under Kyoto. So my assessment of that target is that it's not very ambitious at all.
The numbers that are referred to were taken from this BRIC that the IPCC Working Group III put together. They're based clearly on some assumptions. One may debate some of those assumptions, but we have said in the IPCC for several years that if we are going to avoid dangerous interference with the climate and stabilize emissions at a level that achieves that, then emissions are going to have to decline significantly from what they are now, to perhaps as much as 10% of what they are now.
