Mr ABBOTT (Warringah—Prime Minister) (15:04): I am happy to take the question because, underneath the attempted humour, I presume there is a serious intent. The member asking the question wants to know what the policies of the United States government and the Australian government on climate change have in common. I can tell him that there is no carbon tax in the United States. There is no emissions trading scheme in the United States. This government is determined to ensure that there will be no carbon tax or emissions trading scheme here in Australia. What the United States is doing is taking sensible direct action steps to reduce its emissions, which is exactly what this government is proposing to do. We are proposing to put sensible measures in place to protect our environment. It is not sensible to protect the environment by damaging the economy, and that is why neither the United States nor Australia should have a carbon tax. Mrs Griggs: Madam Speaker, I rise on a point of order. The former Treasurer, the member for Lilley, made a number of unparliamentary comments while the Prime Minister was speaking, and I ask that he withdraw. The SPEAKER: The member for Lilley would assist the House if he withdraws unhelpful remarks. Mr Swan: I withdraw.
