Carbon tax proposed by Nordhaus

William Nordhaus backed a carbon tax instead of the Kyoto protocol approach.

To bet the world's climate system on the Kyoto approach is a reckless gamble", he told the climate change congress in Copenhagen. "Taxation is a proven instrument. Taxes may be unpopular, but they work. The Kyoto model is largely untested and the experience we have tells us it will not meet our objective — to stablise the world climate system."
