Senator WONG (South Australia—Minister for Foreign Affairs and Leader of the Government in the Senate) (14:35): I thank the senator for the supplementary question. I can say to him, as someone who, unlike some in this place, does believe in the benefits of utilising the market for good, rather than for bad, that we do need integrity in the system of carbon credits to ensure that there is additionality, that we're actually reducing Australia's emissions and using an incentive to do so. I have seen some of the reporting, including, as the senator says, from firms engaging in the market. I understand the concerns he's raising. Can I say to him that these are some of the reasons why Minister Bowen has taken the view that an independent review is appropriate, and that is underway. The PRESIDENT: Senator Pocock, a second supplementary?
