My question is to the Treasurer. I refer the Treasurer to his own economic note of three days ago, where he said that only the biggest polluters, less than 1,000, will pay for the pollution they emit. I ask whether the Treasurer agrees with the Prime Minister that Ross Garnaut is 'a serious economist' and whether he therefore agrees with Professor Garnaut, who has just said:

Australian households will ultimately bear the full cost of a carbon price.
