I am sure that they are not only beating us, but far exceeding us on per capita hydrocarbon emissions, which are much more potent green house gases. If they were to install catalytic converters, I am sure that they would beat us per capita on carbon dioxide emissions and the net global warming potential of their emissions would more than likely decline. This would mean that carbon dioxide is good for the environment, although I doubt you will accept that.

Carbon dioxide is clear and I doubt there is much being emitted from that factory. What you are seeing in that picture are hydrocarbons. If the smoke was white, you would most likely be seeing water vapor, which would indicate that the hydrocarbons have been converted into carbon dioxide as carbon dioxide is clear; carbon dioxide is also much better for the environment.
