I note, also, that the cost containment reserve, where the Government will put back into the market other units to ensure that the price stays within that containment reserve, I think that's also a very important point that we need to understand, and I want to hear a lot more about that through this process. Carbon budgets and the ETS, or the carbon budgets with the sinking lid that we will effectively have on our emissions through the ETS, is the best way for us to manage our emissions. It's far better than utilising a policy approach which is a top-down approach, which I note that the Government seems to be quite keen on. The Climate Change Commission talks at great length about policies. They also talk about us walking more and cycling more and put a number on that, so I'm not quite sure how they think they're going to manage that.
