Senator BOSWELL (Queensland) (14:29): I have a question for Senator Wong as the minister for climate change. Can the minister explain what purpose it will serve for Australia to enter into a carbon tax— Honourable senators interjecting— The PRESIDENT: Wait a minute. I am trying to hear Senator Boswell. Senator BOSWELL: I have a question for Senator Wong in her capacity as minister for climate change. I now want to ask the question. The PRESIDENT: Yes, you are right. Senator BOSWELL: I was interrupted. The PRESIDENT: You are quite all right. Senator BOSWELL: My question is for the minister for climate change. Can the minister explain what purpose it will serve for Australia to enter into a carbon tax when our emissions are only 1.4 per cent but, in comparison, China's carbon emissions will rise by 496 per cent and India's emissions will rise by 350 per cent by 2020? Even if we reduce emissions by an effective 30 per cent on a business-as-usual basis by 2020, won't it be utterly meaningless in the context of projected massive growth in emissions, particularly from China, India and Indonesia?
