Senator WHITTEN (Western Australia) (14:51): My question is to the Minister representing the Minister for Climate Change and Energy, Minister Ayres. What percentage of annual global CO2 emissions is Australia responsible for? I'll give you a hint. It's one per cent. The PRESIDENT: Thank you, Senator Whitten. I think the whole point of question time is that you ask the questions and the minister answers them. But I'll call Minister Ayres.
