HAMISH WALKER (National—Clutha-Southland): Madam Chair, thanks very much, and I just thank the Minister for Climate Change for his previous answers. My question's reasonably specific, and it's to do with the Tīwai aluminium smelter. Anyone who hasn't been there needs to go there for a visit. It's a wonderful place. My question's really around the industrial allocation phase-down, mainly from 2030, and what the Minister plans to do in terms of carbon leakage. So industries here that are taxed to the hilt—where they see it's no longer feasible to continue, that industry will, basically, just go offshore, and someone offshore will produce it, often, the majority of times, through a much higher emission rate.
