My question is to the Prime Minister. I refer the Prime Minister to the fact that sulphur hexafluoride, a synthetic greenhouse gas widely used in the power industry and even in eye surgery, will face from Monday a carbon tax of $549,000 per tonne, an import application fee of $15,000 per tonne and a handling fee of $165 a tonne to help pay for the carbon tax bureaucracy. Will the Prime Minister stand by her claim that only a few hundred businesses will pay the carbon tax?
