Senator EDWARDS (South Australia) (14:45): Mr President, I have a further supplementary question. Given that the report also showed that the total Australian government energy use and intensities rose by 11.45 per cent from 2008-09, can the minister confirm whether the government has calculated the extra cost to taxpayers from this government's own spiralling emissions during the planning of this pointless tax? If the Australian government cannot get its own house in order, is it not hypocritical to expect everyday Australians to do the same?
