I thank the shadow Treasurer for asking me the same question he asked me before and the answer is, of course, the same. We have been committed to an emissions trading system for many years. The shadow Treasurer was committed to an emissions trading system until about a year or a year and a half ago when he changed his mind, proving yet again that he has no principles whatsoever. We are committed to an emissions trading scheme. We have announced a scheme with a fixed price moving to a floating price. That is what we have done. We said all the way through the election campaign we were determined to price carbon.
