Ventilation corridors to cleanse Beijing's air

The answer to Beijing’s smog crisis may be blowing in the wind. China’s capital plans to create five major “ventilation corridors” in an effort to improve wind flow through the city, CCTV-America reports.

The passageways could enable steady breezes that would remove pollutants and cool temperatures, the article says, citing a report by the state-run Xinhua News Agency. They would run in a north-south direction. The main corridors would range from 80 meters (262 feet) to 500 meters (1,640 feet) in width, supplemented by smaller wind tunnels. Citing a government source, Xinhua says, ”construction in these zones will be strictly controlled, and obstacles along the way will be gradually removed.” 

Shanghai, Fuzhou, Nanjing and Wuhan are among the other Chinese cities pursuing a similar strategy to reduce air pollution, the news agencies report. Beijing plans to implement the corridors as part of a wider pollution reduction effort that includes artificial intelligence, coal plant closures and limits on factories.

Some experts are skeptical. Peng Yingdeng, a researcher with a Chinese pollution engineering research center, predicted that the corridors would have a limited impact, the article says.
