Senator CORMANN (Western Australia—Leader of the Government in the Senate, Minister for Finance and Vice-President of the Executive Council) (14:37): There is a recognised global challenge which we believe needs to be appropriately addressed in a global fashion through an appropriately comprehensive global arrangement. Australia, as a responsible international citizen, is committed to doing its bit. That is precisely what our government are doing. Under our government, emissions are coming down and electricity prices are also coming down. We are keeping the lights on, bringing electricity prices down and helping to reduce global greenhouse gas emissions in a way that is economically responsible. We are very proud of our record and we remain committed to that as the appropriate way forward. The PRESIDENT: Senator Roberts, a final supplementary question?
