Australia’s House of Representatives has just passed legislation for a carbon tax[1]. Passage by the Senate is assured, so that, as long as the government can survive another year (it needs the support of three independents to muster a one-vote majority), the tax will come into effect in mid-2012. The political history of this proposal is too complicated to recount, but is symbolised by the current Prime Minister (who previously dumped the policy, but has now succeeded in bringing it into effect) receiving a congratulatory kiss from the previous Prime Minister (who supported the policy but was unable to get it passed into law, and was replaced as a result of this).[2]
