Researchers see complexity in China’s emissions

China is "succeeding at some of the big but simpler problems and really just getting started on more complicated secondary pollutant problems," said Chris Nielsen. (Photo courtesy of Flickr user Andy Enero.)
Research by Chris Nielsen, Executive Director of the Harvard China Project, and colleagues at Nanjing University and Jiangsu Provincial Academy of Environmental Science in China was cited in a Wall Street Journal article titled "China Clean Air Bid Faces Resistance" (January 22, 2013). The research, published in the journal Atmospheric Chemistry and Physics , examined the effect of China's national policies on the emissions of carbon dioxide and atmospheric pollutants from anthropogenic sources over the period 2005 to 2010. The following is an excerpt from the Wall Street Journal article, by Brian Spegele and Wayne Ma, which is available in its entirety here. Growing evidence suggests China's programs to cut emissions from coal-fired power plants-traditionally a major source of its massive pollution problems-have had some success. But that is being partly undermined by rapidly rising industrial output, such as coal-fueled steel production, and lagging fuel standards for China's ballooning numbers of cars and trucks. In addition, analysts say emission goals that target specific pollutants aren't enough to stem wider air-quality problems. "The potential of reduction for power plants is small," said Zhao Yu, who researches atmospheric pollutants at Nanjing University.
