I had the pleasure on the weekend of speaking to a group in Marlborough called the Climate Karanga, who are very keen climate activists, who actually don't understand the emissions trading scheme (ETS) that well. And I'm finding—that's no criticism of those people at all, but it is quite a complex thing that we're talking about here. And I think it's more than just doing the functionary things correctly; we have to take people with us. They have to own this, because they're going to pay for it one way or another. They're completely unaware that they're paying for carbon emissions now—at the fuel pump, for example—and when I explained that to them, it was a bit of a shock. Most of them drove Nissan Leafs, and I pointed out to them that, while they may be lowering their emissions, they're not lowering the country's emissions, because they're simply making it cheaper for other emissions certificates to be purchased on the open market because they won't be requiring them. And we have a set number of units that are going into the market. It's a very simple process once you get your head around it, but it takes a little bit to get there.
