Senator CORMANN (Western Australia—Minister for Finance and the Public Service, Vice-President of the Executive Council and Leader of the Government in the Senate) (14:19): I think that is a gross oversimplification. I'm looking at Senator Colbeck, who has a fantastic front page, if someone could pass that on to me? Remember Dr Bob Brown? You know what he said? 'Coal power—best option'. That was of course when he was opposing the hydro power in Tasmania. It is true that coal is one important energy source and is also an important export product for Australia, but on our side of the Senate, on our side of the chamber, we are committed to effective action on climate change in a way that is economically responsible. What that means is we're pursuing sensible policy when it comes to promoting renewable energies— (Time expired) The PRESIDENT: Senator Di Natale, a final supplementary question.
