The other thing that I'd like to ask the Minister is that the bill makes this regulation power to vary the phase-out date after 2030, but only if it's recommended by the Climate Change Commission. Now, it's always been our position that the commission should have recommendation powers only, and I'd just be interested in the Minister's view on that. We heard from New Zealand Steel and we heard from O-I Glass and a number of other trade-exposed industries, and they talked about the lack of certainty and the lack of any technology coming on the horizon that's going to allow them to meet these targets, and so they are facing significant costs in the future if the allocation of units is phased down, and they certainly didn't think this bill brought them certainty.
