China has scaled up air quality control in Beijing to make sure the capital's air pollution to be much improved by the time of the 2022 Winter Olympic Games.

 

BBQ is the latest target as Beijing announced on Wednesday to ban restaurants from operating outdoor barbecues, which authorities say are a major contributor to smog, in selected suburban areas.

 

China is going all out to bring "Olympic Blue" to Beijing.

 

During last November's APEC meeting, host Beijing imposed strict pollution controls which led to a big drop in pollutants in the air. Thus, Beijing netizens coined a phrase 'APEC Blue' to describe the clear blue sky.

 

Air pollution, which had haunted the city for quite a long time, is believed to be one of the major problems hurting Beijing's chance for the 2022 Games.

 

The average density of PM2.5 (airborne particles smaller than 2.5 microns in diameter) dropped by 19 percent in the first quarter compared with the same period last year.

 

The average densities of PM10, sulfur dioxide and nitrogen dioxide also dropped by 8.8 percent, 42.9 percent and 11.4 percent respectively in Beijing.

 

Meanwhile, the air quality in nearby Tianjin Municipality and Hebei Province also improved in the first quarter.

 

The PM2.5 density dropped 15 percent in Tianjin and 25 percent in Hebei Province respectively year-on-year in the first quarter.

 

Beijing and the neighboring Tianjin Municipality and Hebei Province have been working together to fight air pollution in recent years. The region has been ordered by the central government to cut PM2.5 from 2012 levels by 25 percent by 2017.

 

The International Olympic Committee will vote on Beijing's bid race against Almaty, Kazakhstan, on July 31 in Kuala Lumpur.
