Senator CORMANN (Western Australia—Minister for Finance, Vice-President of the Executive Council and Leader of the Government in the Senate) (14:27): Australia's committed to effective action on climate change. The debate that we've had in Australia over the last decade is about what the best methodology would be to achieve effective global greenhouse gas emissions in a way that is economically responsible. We think it is very important to maximise the emissions reduction effort in a way that is economically responsible. Of course, our success in securing emissions reductions in a way that is economically responsible and doesn't undermine the opportunities for working families to get ahead is a very important way to lead by example for the rest of the world, because if the rest of the world can see that we can achieve both emissions reductions and economic and jobs growth then other countries will follow our lead. We want all countries to do the best they can to help reduce greenhouse gas emissions in a way that is economically responsible, and I commend that approach to you. The PRESIDENT: Senator Roberts, a supplementary question?
