Senator MILNE (Tasmania—Leader of the Australian Greens) (14:06): My question is to the minister representing the minister for climate change, Senator Lundy. Minister, the Climate Commission has said in its latest report: From today until 2050 we can emit no more than 600 billion tonnes of carbon dioxide to have a good chance of staying within the 2°C limit. Based on estimates by the International Energy Agency, emissions from using all the world’s fossil fuel reserves would be around five times this budget. Burning all fossil fuel reserves would lead to unprecedented changes in climate so severe that they will challenge the existence of our society as we know it today. Honourable senators interjecting— The PRESIDENT: Just a moment, Senator Milne. You are entitled to be heard in silence. Senator MILNE: And finally: It's clear that most fossil fuels must be left in the ground and cannot be burned. Does the government agree with the Climate Commission?
