The lower house of the Russian Duma has voted to ratify the Kyoto Protocol. Although some formal steps remain, this was the last real hurdle to be cleared before the Protocol could come into force.
The only signficant holdouts now are the US and Australia. The Bush Administration has, as expected, said it will do nothing, and Howard will presumably follow. The ratification will pose some significant problems for Kerry, who has tried to sit on the fence so far – his position appears to be that he would seek to renegotiate the treaty to make the terms more favorable to the US. Realistically, this is probably a sensible outcome for the world, but I don’t know in practice how a treaty that’s already in force can be renegotiated unless all parties agree, which seems unlikely.
