Not all that true. CO2 stack emissions, especially from electricity generation, are likely proportional to other pollutants-- which are more localized. China (and India) already suffer from some of the worst air pollution from other pollutants that are byproducts of burning coal, such as mercury, varoius VOCs and HAPs. As those societies rapidly prosper, their populations clamor for better air. China has some of the biggest spending plans for solar power, for example. And India has been collaborating with the U.S. to capture a lot of indutrial methane and reuse it using technologies benchmarked under the U.S. Natural Gas Star program, for example. What the U.S. can do is be an exporter of technological knowhow for green technologies. There is no easy solution to the carbon problem, otherwise it would have been implemented already. No "clean-coal" for example, and nuclear power isn't without its side effects either.
