The debate over command and control versus incentives is about to heat up. From Reuters (U.S. to announce 'Beyond Kyoto' climate pact):
The United States, the world's top polluter, is set to unveil a five-nation pact to combat global warming by developing energy technology to cut greenhouse gas emissions, officials said on Wednesday.
[...]
Details of the pact were unclear but it appears to echo recent comments by President Bush who advocates the use of technology to curb growth in greenhouse gas emissions rather than setting Kyoto-style caps on emissions.
[...]
The WWF urged Washington and Canberra to agree Kyoto-style caps on emissions, saying that any regional energy technology deal was only a partial solution. And it said China and India had promised to take part in talks on widening Kyoto.
I especially like this quote:
"A deal on climate change that doesn't limit pollution is the same as a peace plan that allows guns to be fired," said Jennifer Morgan, head of the WWF's climate change program.
I don't agree, but points for creativity.
