I agree about China.  This is why the Kyoto Protocol, in its current form makes no sense.  As written, the only result of adoption of the Protocol would be to affect a massive transfer of energy-intensive technologies to China and India who would then delay implementation of their own limits ad nauseum.  In the meantime, particularly in China, the loss of intellectual property would be catastrophic.  And actual worldwide emissions would not only not go down, they would continue to rise.  An agreement like Kyoto only makes sense if applied across the board.

That said, there is no excuse for political fence sitting in the United States on shorter term carbon emission limits, tax incentives for cleaner technologies, higher fuel consumption standards for automobiles, and maybe even a stiffer gasoline tax. 

But the US (and a few other countries) will continue to lag behind some of the rest of the world in emissions per capita for quite some time simply due to the epoch in which we were industrialized.
