We also think the carbon budgets and the sinking lid, as I said before, are really important, and we can see that the ETS is working here in New Zealand. There's quite a debate about the number of farms or the hectares going into forestry, particularly on the East Coast of the North Island, and that is as a result of the high carbon price in New Zealand—at $38 it's trading at at the moment. That is encouraging the market to plant more trees. We also see it working in the transport sector. The Climate Change Commission—I'm somewhat surprised—don't believe that the ETS is working that well, but, actually, we can see that if you hop into a taxi at any time, more than likely it's a hybrid, and it's a hybrid because the taxi drivers are very sensitive to price of their operating expenditure, which is fuel, and hybrids are much cheaper. So they're making a rational market decision, and that's what the ETS does. We should have more trust in that. But, of course, it does depend on having a market that's going to be effective and efficient, and one that participants will have a lot of confidence in.
