You mentioned also, Minister, the EU's ETS and how good it was. Well, I think that's actually a Clayton's ETS, quite frankly. It doesn't include transport and it doesn't include agriculture, and nor should it. Nor does ours, and it shouldn't either, until such time as our trading partners do. I think we too often take the EU as a shining example when we're the market leaders in this, not the followers, and I think we should be proud of our ETS. It is quite well constructed, particularly now it's capped. We can manage our emissions down, and I think that this auction is of course an important part of that.
