Emissions target – floor or ceiling?

Q: Some people have said that they would like the 43% emissions reduction target to be a minimum ‘floor’ that should be surpassed with greater reductions. Others have said it should be a maximum ‘ceiling’ that Australia should aim to achieve, but nothing more until other countries have agreed to or achieved higher levels. What is your own opinion?
