From Bloomberg.com --Australia will need to buy extra credits if its emissions exceed the assigned amount under rules of the protocol. It can sell spare credits if its emissions rise less than 8 percent from 1990 levels.

“ Australia reduced its estimate of assigned emission credits under the 1997 Kyoto Protocol by 1.1 percent after a review by a team of United Nations experts, giving the nation the sixth most generous allocation. ”
