China and India's GDP is growing faster than their growth in CO2 emissions. Those figures I gave were from 1998; here's some figures for what's happened since.
Country USA China India
1998 CO2 5569 2952 844
2001 CO2 5739 3050 922
CO2 %growth/year 1.0 1.1 3.0
avg GDP growth 98-02 3.0 7.6 5.4

So the USA's GDP is outpacing CO2 growth by 2% a year; China by 6.5%, and India 2.4%. Those developing countries are getting more efficient.
Or take the DOE's prediction:
"In developing Asia, fairly rapid improvements in carbon dioxide intensity are expected for China and India over the projection period, primarily as a result of rapid economic growth rather than a switch to less carbon-intensive fuels. Both China and India are projected to remain heavily dependent on fossil fuels, particularly coal, in the IEO2003 reference case, but their annual GDP growth is projected to average 5.9 percent, compared with an expected 3.4-percent annual rate of increase in fossil fuel use from 2001 to 2025."
