2015年CRI 北京空气质量有所改善

 

Latest stats from the city's Environmental Protection Bureau show the number of days with high air quality reached 57 in the first four months of 2015, up eight days from a year earlier.

During the period, the number of days with severe air pollution decreased 42 percent year on year.

Meanwhile, the concentration of sulfur¹ dioxide and fine particles less than 2.5 microns in diameter was reduced by about 43 percent and 19 percent, respectively.

The Chinese capital, along with its neighboring Tianjin Municipality and Hebei Province, has suffered from severe air pollution for years, with excessive coal use and car emissions³ among the key culprits.

Amid the country's stepped-up campaign against pollution, the three areas have decided⁴ to join hands.

Li Lixin heads the air pollution control division of the Beijing Municipal Environmental Protection Bureau.

He says the concerted effort has led to a big drop in pollution from coal-fired plants.

"The coal consumption in Beijing, Tianjin and Hebei has been cut by 19.8 million tons. Meanwhile, we have replaced 3.9 million tons of faulty coal with high-quality coal in the rural areas in those regions."

In its latest step, Beijing dismantled⁵ four remaining largest coal-burning boilers⁶ in the urban area in this past week.

According to the city's blueprint⁷, the Dongcheng District in the downtown area will be coal-free in the future, while coal-burning boilers in other urban areas will be replaced with less-polluting ones.

Meanwhile, the city has also seen a decrease in car emission², another key contributor to pollution.

Li Kunsheng is also from the Beijing's Environmental Protection Bureau.

"Though car ownership in China has been increasing in recent years, vehicle emissions have actually decreased year on year."

As part of its anti-pollution move, Beijing has enacted⁸ strict restrictions⁹ on car use in the country.

Under a lottery-style quota¹⁰ system, its residents have to compete for limited license¹¹ plate numbers before buying a vehicle, while cars have to be kept off road for one weekday per week, depending on the final digit¹² of their license plate.

In the next step, the city may adopt a plan that will require residents to have first secured a parking space before purchasing a vehicle.

To reinforce the car-limiting effort, Beijing has also reached an agreement with Tianjin, Hebei, Shanxi, Shandong, Henan and Inner Mongolia to share car emission data and carry out cross-region law enforcement against drivers who breach¹³ emission limits but have their cars registered in other cities.

Beijing's authority has vowed¹⁴ to further step up its efforts to combat pollution in the wake of its bid for the 2022 Winter Olympics.

The city's urban center expects a 25 percent reduction in PM2.5 pollutants¹⁵ under a five-year plan that began two years ago.

By 2017, Beijing will have reduced the amount of coal burned in the city to 10 million tons from 23 million tons in 2013 and taken whole fleets of old, polluting vehicles off its roads.

The city's government has vowed to devote 48 billion yuan, or about 8 billion US dollars, to this effort.
