Air pollution is a sensitive topic in China, spurring public protests every year about environmental degradation, particularly from factories. Now, plans have been announced by the Xinhua state news agency that authorities in Beijing are developing a network of ventilation “corridors” to help tackle the city’s notorious air pollution. There will be five large corridors that will be more than 500 meters wide and several smaller ones. This could be part of a plan for Beijing to reduce pollution by 40% from 2013 levels by 2020.
