The problem we're trying to solve here through an emissions trading scheme is not just a problem for this House or this Parliament to solve; it's an environmental problem that is a global problem, and our obligations as a nation, while we might disagree on the volume or the timing or the cost of those obligations—we must have a nationally agreed approach. Thinking about the type of coalition that would be ideal in that nationally agreed approach, it would have to involve the businesses who are most exposed to the price of carbon, and those businesses are doing a social good. They are providing fuel. They're providing energy. They're providing jobs in the regions, and those jobs support communities, which in some regions of New Zealand have very few other opportunities for employment and for social mobility. So it's really, really important that any mechanism that the Government uses to set a price for carbon or establish a confidential reserve price at auction has the buy-in of not just political party leaders but those communities and those sectors of the economy which are most impacted by it and which would have the most to lose, as well as potentially some gain.
