Tempting as it is, my question is not to Senator Arbib. My question is in fact to the Minister representing the Minister for Climate Change and Energy Efficiency, Senator Wong. I refer the minister to various assumptions made by the government in deciding to pursue a carbon tax and the similar assumptions in modelling the impact of a carbon tax in relation to the extent of complementary action elsewhere in the world. Are the government's expectations on the extent of international pricing of greenhouse gas emissions, whether through carbon taxes or trading schemes, currently being met?
