If these threats to health and other problems associated with climate change are to be avoided, Australia needs to take strong decisive action. The science is sufficiently clear to warrant a reduction in Australia’s greenhouse gas emissions of at least 60 per cent by 2050. DEA strongly supports the development of an emissions trading scheme and believes that it will play an important and prominent role in moving Australia’s emissions profile towards this target. A national scheme would ideally be initiated by and coordinated by the Commonwealth Government. However as such action is not forthcoming, the joint initiative by the States and Territories Governments is to be commended.
