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."
The answer has been staring us in the face for a while now. And more and more people - from business to politics to the greens - are catching on. It has an inelegant name:
contraction and convergence (C&C).
It works like this. The world needs to contract emissions by more than half by the middle of the century. It's do-able and it won't wreck the world economy. (Bankers on a spree are far better at doing that.)
But there will be some pain. The only way of sharing out that pain fairly is for everyone to take on emissions targets, but targets that are fair because they are based on a basic parameter of need. That is: population size.
So every country should head towards annual emissions proportionate to its population. Most would have to reduce their emissions; but some of the poorest countries could raise them. That's the convergence part of the formula.
Of course, to ease the pain and make investment more efficiently, there would be massive carbon trading in the same way as is already allowed for under the Kyoto Protocol.
It's simple and it's obvious. Tony Blair's shuttling climate diplomats get it.
Nicholas Stern, author of the groundbreaking report on the economic perils of climate change back in 2006, gets it. In Washington and Paris and New Delhi, some influential figures get it. "It's where we will need to end up, of course, even if we can't quite work out how to get there," one UN leading negotiator told me recently.
Why doesn't the world admit it and get on with it? Surprisingly, one reason is the long-term opposition of most environmental groups to the plan. I find this baffling and dispiriting.
Why the hostility? One reason seems to be that it is the brainchild of a maverick and sometimes truculent campaigner living in London called Aubrey Meyer.
So the likes of Greenpeace and Friends of the Earth can't claim ownership. And even the more radical climate campaigners - like the Guardian syndicated op-ed writer and blogger
George Monbiot - have got cold feet.
Monbiot, a former supporter of C&C, has recently started publicly backing a proposal from his old mate Oliver Tickell, called
Kyoto2, which would set up an international agency to control not emissions of greenhouse gases but the production of fossil fuels themselves.
Well, I can see why politically he wants to take on the fossil-fuel leviathans. But the beauty of contraction and convergence is that it doesn't require a global fossil-fuel autocracy; it is transparent, self-evidently fair and tackles the problem, not a surrogate.
If climate change is the central challenge for the world in the 21st century, then C&C is the most, perhaps the only, viable long-term solution on which there can ever be international agreement.

Just another Eurocentric view of "equality" I'm afraid.
