My question without notice is to the Minister for Climate Change and Water, Senator Wong. I ask why, having snubbed the Senate last week on a question about the announcement of mid-term emissions trading targets, the minister announced at 4.22 pm on Friday that she would be announcing that target the day after she returns from Poznan. I also ask the minister: on the business of pursuing a global agreement to stabilise emissions, will the Australian government’s position going to Poznan be 350 parts per million carbon dioxide equivalent in the atmosphere, which is safe; a dangerous 450 parts per million; or a known catastrophic potential of 550 parts per million?
