Foreign demand for goods adds to air blight

Study reveals connection between emissions and goods for export

Manufacturing goods in China for export contributes significantly to the country's severe air pollution problem, a recent study showed.

The research, conducted by nine Chinese and international scholars, showed that in a sample year, 2006, about 36 percent of sulfur dioxide, 27 percent of nitrogen oxides and 22 percent of carbon monoxide that was emitted by human activities came from economic processes related to exports.
