Look, thank you, Mr Chair. This is a complicated, multifaceted, detailed piece of legislation. The bill itself—the document that's sitting on the Table—runs to in excess of 400 pages, and so as the debate on the specific clauses and sections of the bill pursues this afternoon, I and my colleagues will want to ask the Minister a number of questions about the practical application of this piece of legislation. And, in so doing, we are very cognisant on this side that, actually, this is the "doing" piece of the climate change reform package that the Government has introduced. The first portion of the legislation was the zero carbon Act, and that, essentially, set up the framework for the establishment of a commission and the various targets around time frames and gases for reduction. But this emissions trading scheme piece of legislation is the one that actually provides the Minister of the day with the levers to have an impact on the day-to-day lives of New Zealanders through a pricing mechanism that is our emissions trading scheme. And, effectively, that's exactly what it is: it's a piece of statute that is designed to, effectively, reward good behaviour and, effectively, punish poor behaviour in terms of carbon emissions.
