My question is to the Prime Minister. I refer the Prime Minister to the fact that BlueScope Steel is one of the most environmentally responsible steelmakers in the world and that, if a carbon tax pushes more steel manufacturing overseas to China—where they will emit more carbon dioxide for every tonne of steel—it will mean that total global emissions will increase, not decrease. I ask the Prime Minister: why is the government threatening thousands of manufacturing jobs in Australia with a carbon tax that will have the effect of increasing emissions as industry and jobs migrate overseas?
