The Chinese capital imposed the highest tier of a four-color smog warning system for four days starting Saturday, the second time the red alert was applied since Beijing established the pollution precaution scheme in 2013.
As part of the “emergency response plan,” 2,100 factories in the city and on its outskirts have been ordered to either stop or scale back production in an effort to cut emissions, an official from the Beijing Municipal Commission of Economy and Information Technology, who declined to be named, told AFP.
