Another speech, another step closer to the policy that will not die: Greg Combet yesterday gave a couple of further clues as to why Labor’s preferred carbon price scheme will be the CPRS under another name.

Remember, Labor did its best to kill the CPRS. First they never sold it properly. Then they dumped it … sorry, delayed it. Then, just to make sure, they dumped the prime minister who oversaw it. Then, as if that wasn’t enough, they swore black and blue there wouldn't be a tax on carbon after the election.
