A new study, published in the journal Proceedings of the National Academy of Sciences, found that manufacturing in China is responsible for some of the air quality issues throughout the western portion of the U.S. While outsourcing production to the Asian country has reduced emissions in certain regions of North America, about 12 to 24 percent of the pollution on the West Coast can be traced back to Chinese production, CNN reported.
Despite the fact that areas such as the U.S., Japan and Europe have decreased emissions over the past decade, global emissions of air pollutants have remained high during that time. Much of the pollution can be attributed to the rising emissions produced from China, the study found.
"Outsourcing production to China does not always relieve consumers in the United States - or, for that matter, many countries in the Northern Hemisphere - from the environmental impacts of air pollution," the researchers wrote, as quoted by the Los Angeles Times.
