I was interested to hear Mr Simpson talk about industrial allocations. Now, all we are asking—what this bill does is a very, very simple thing. It's a complex piece of machinery but the principle is simple. It says, "Carbon emitters should bear the cost of their emissions.", and this is a pricing regime to achieve that. But, as Mr Simpson points out, there are some industries which, if we asked them to bear the full cost, then it's likely that the industries would move overseas and be less carbon efficient. Now, that can't go on for ever. We can't keep giving New Zealand industries a free ride, but we want to transition them.
