Mr ABBOTT (Warringah—Leader of the Opposition) (14:53): My question is to the Prime Minister. I refer her to the Productivity Commission report on the relevant matter at page 50 which says: … no country currently imposes an economy-wide tax on greenhouse gas emissions or has in place an economy-wide ETS. How does the Prime Minister justify her statement, made a few moments ago in this House, that there are other countries that have bigger carbon taxes than the one she plans for this country?
