I do share the colleagues'—both Stuart Smith and Erica Stanford's—concerns that the Government is confused around its climate change policy and around its financial instrument as to whether it really is committed to an emissions trading scheme, or whether it continues to amend the scheme to make it more and more like a carbon tax. The reason members on our side of the House are cautious of amendments of that sort is we want real progress on climate change, but we do not want to create a legislative framework which makes the ETS a backdoor tax.
