Hon JAMES SHAW: Well, what I'm saying is that, actually, the prices that households are paying for their petrol—same amount of petrol if you're driving around—are considerably lower today than they were three months ago. And that, actually, if COVID-19 hadn't shown up, and, you know, the economy was humming along, and we're at capacity constraints, and all of that kind of stuff, then prices would be higher because of the pressure in the economy, and, therefore, that marginal additional difference would be felt a great deal more at that moment. So I guess what I'm saying is: I dispute the central notion that now is the wrong time because, actually, prices are so much lower right now than they would normally be that you don't notice it. This is the point about a market mechanism, of course, is that it changes depending on the conditions in the market. Carbon prices themselves are lower now because there is less demand for units because, for example, Air New Zealand is flying less than they have, and so their requirements for units have really shrunk. Therefore, prices have come down. And that's a fundamental difference between an emissions trading scheme and a carbon tax, for example. A carbon tax is simply a staged increase over any number of years—just wanted to say something about that.
