Senator CORMANN (Western Australia) (14:23): Mr President, I ask a further supplementary question. Given emissions from aluminium production in China are 50 per cent higher than emissions from producing aluminium in Australia, is it not true that a carbon tax which makes Australian manufacturers less competitive will actually cause an increase in global emissions when this is supposed to be about reducing global emissions? Why is the government so intent on forcing Australians to make significant sacrifices through higher costs of living and fewer jobs when its carbon tax will end up increasing global emissions instead of reducing them?
