Fred's Footprint: The best solution to climate change

What's the best way to fix climate change, to stamp out the emissions that are warming our planet? I don't mean what technology. That's actually coming along quite nicely. I mean what are the international legal and financial levers that can pulled to get the technology, on the scale needed, from the test rigs to the national grids?

Later this month, in Accra, Ghana, the UN's lumbering Kyoto negotiations will have another stab at what to do after 2012. They will come up against the familiar stand-off. On the one hand, is the rich world's reluctance to accept emissions limits that will add to the cost of doing business unless developing countries subscribe to emissions controls. On the other, developing countries utter their familiar (and not unreasonable) cry: "You caused the problem; you fix it."
