China, crowned as the "world's largest producer of carbon dioxide" might get relieved by the results of a report published in Proceedings of the National Academy of Sciences (PNAS) in its March 8th edition. The reports say that the trade emissions should also be taken into consideration as the scientists from the Carnegie Institution of Washington at Stanford University has revealed that one third of the CO2 emissions are because of exported or imported services and products.

About the emissions in China, Ecologist at the Carnegie Institution for Science, Steve Davis stated, "Nearly a quarter of the emissions that are produced in China are ultimately exported to consumers elsewhere. It was pretty surprising to see that between a third and a half of all the emissions related to goods consumed in European countries actually occur outside of their borders".

Davis said that this report provides basis for "ethical arguments" which prove that developed countries "should lead the global mitigation effort".

US cannot slip through the problem by just blaming China for the emissions, as US consumes carbon-intensive products that are imported and these emissions are a result of using coal and natural gas.
