Senator CONROY (Victoria—Leader of the Government in the Senate, Minister for Broadband, Communications and the Digital Economy and Minister Assisting the Prime Minister on Digital Productivity) (15:01): Those opposite continue to try to airbrush out of history their own, Howard government position on this issue. It is just, 'Nothing to talk about over here; move on, move on,' because Mr Howard took, to the 2007 election, a carbon price. Honourable senators interjecting— Senator CONROY: I know it's hard! Honourable senators interjecting— The PRESIDENT: Order! Order on both sides. Senator CONROY: Because this is what Mr Abbott said—this is what he said; he just airbrushed it out of history: The Howard Government proposed an emissions trading scheme because this seemed the best way to obtain the highest emission reduction at the lowest cost. That was from his own book, on page 171. Then, of course, he said that the politics of this issue have changed. I think the politics of this issue have changed dramatically, because he had already described in very unflattering terms, which I suspect you would make me withdraw if I repeated— (Time expired) Senator Conroy: Mr President, I ask that further questions be placed on the Notice Paper.
