The Greening Of The Stimulus.(International Edition; THE LAST WORD)(interview with David King)(Interview)

Let GM collapse. Rather than waste taxpayer money, use it to fund small high-tech companies with new car designs.

Sir David King has been a climate guru since the earliest days of global warming. The director of Oxford's Smith School of Enterprise and the Environment and the former chief scientific adviser to Tony Blair, King was instrumental in developing Britain's new $1.5 billion Energy Technologies Institute for clean power. He sat down in Aarhus, Denmark, with writer Michael Levitin to discuss Britain's nonpartisan approach to environmentalism, American leadership and the coming U.N. climate summit in Copenhagen. Excerpts:

LEVITIN: How hopeful are you about reaching a climate agreement in Copenhagen?

KING: There are four elements we need to make the talks work. One: agreeing on a global carbon-stabilization level, saying we'll stay below X parts per million greenhouse gases by the end of the century. Two: agreeing on national targets that set carbon trajectories on a country-by-country basis according to where they are now and where they need to be. Three: putting fiscal mechanisms in place like carbon tracking, a cap-and-trade system, etc. And four: creating a fund to transfer technology and assist developing countries in adaptation. If the package is any less than that, then it's got to be an interim package.

What do you make of Prime Minister Gordon Brown's climate policy?

I'm really pleased about Brown's speech to the U.S. Congress, pushing stimulus funds toward creating a low-carbon economy. In Britain, all three political parties are vying with each other to be tougher on climate change. It was the opposition leader, David Cameron, who announced his Conservative Party's policy should be 80 percent CO2 reductions by 2050, and the next thing we knew Brown was calling for 80 percent reductions by 2050.

What impact is the economic crisis having on the climate debate?
