So intellectually, it would be a more honest position for the National Party to take to say, "Actually, we think that acting on climate change is only ever a cost and an impost, that there can be no benefit from it, and therefore let's just give up on it, let's forget about it. Let's get rid of the emissions trading scheme, let's get rid of the zero carbon Act, let's take no action on climate change at all." because the mentality that's coming through is that it only has a cost, but it doesn't. The evidence is actually that once you get started—and the hard part is getting started, and we've never really gotten started in this country—the transition is faster and cheaper than any of the modelling ever suggests. So I think that the basis of the argument that we need to defer only ever increases costs on future generations of taxpayers and households, and that's why the situation that we're in—we want to avoid that. And because prices are lower at the moment, the cost in the margins now simply won't be felt.
