The deadline for submissions on the Review of the Emissions Trading Scheme and related matters - originally tomorrow - has been extended. So we have two more weeks to have our say on the future direction of government climate change policy.
Unfortunately they still don't have electronic submissions enabled (I'm told that will be rolled out by June), so it'll have to go in hardcopy.
If you're thinking about it, there is a handy guide to making a submission here [PDF].
