The discharge of pollutants in Beijing and bordering Hebei province and Tianjin is expected to be cut by a third during Asia-Pacific Economic Cooperation meetings from Nov 5 to 11, thanks to air pollution control measures.
"China will take the highest-level measures to guarantee air quality during the APEC meetings," said Chai Fahe, vice-president of the Chinese Research Academy of Environmental Sciences.
"It is expected that the pollutants discharge in the Beijing-Tianjin-Hebei region will be reduced by 30 to 40 percent, and the air quality will hopefully be further improved."
Chai said that since June, Beijing has shut down some power stations, eliminated old vehicles and boilers, used clean energy, closed more than 300 polluting factories and upgraded technologies to cut emissions.
The capital will also restrict cars based on an odd-and-even-number rule, almost halving the number of cars on the road during the APEC meetings.
In addition, major polluting businesses will be ordered to cut production, and work on some construction sites will be suspended.
