My question is to Senator Minchin, the Minister representing the Prime Minister. Hasn’t the government had an array of different positions on carbon trading over the past 10 years, including: rejecting proposals for putting a price on carbon in 1997 and in 2003; the minister himself and the Treasurer saying that Australia will only join a global trading scheme in the long term; the Minister for Industry, Tourism and Resources saying we might join a regional trading scheme in the medium term; and the Prime Minister, under political pressure last year, setting up a committee?
