New Study Says Car Exhaust Still Largest Contributor to Beijing's Air Pollution
After trying to blame chuan'r grills and factories in Hebei, the Ministry of Environmental Protection has cited car exhaust as the leading cause of Beijing's air pollution, China Daily reported Wednesday.
Two-thirds of the pollution Beijing suffers is generated from within the city, while the other third is blown in from surrounding areas such as Hebei.
The MEP's analysis indicated that of the PM 2.5 pollution generated from within the city limits, 31 percent come from motor vehicles, 22 percent from coal burning, 18 percent from industrial production, and 14 percent from dust.
Smog is also the top pollution culprit in Hangzhou, Guangzhou, and Shenzhen, the report said. Dust and industrial pollution are the leading causes of air pollution in Shanghai, Tianjin, and Ningbo, while the burning of coal is the number one cause in Hebei province's Shijiazhuang and in Nanjing.
Beijing closed three of its four coal-burning plants, and will shutter the fourth in 2016, but recently has taken no meaningful action to reduce pollution from automobile exhaust, such as permanently implementing the odd-even license plate restrictions that proved effective both during the 2008 Olympics and the November 2014 Asia-Pacific Economic Cooperation meeting.
"Severe" pollution affected Beijing and neighboring Hebei province 156 days in 2014, or 42 percent.
