China News Agency, Beijing, January 9th (Chen Hang Duyan) From the raging haze to the return of the blue sky, Beijing’s air quality has improved significantly in recent years.
Liu Baoxian, director of the Beijing Municipal Ecological and Environmental Monitoring Center, pointed out in an exclusive interview with China News Agency "China Focus" that Beijing’s air pollution control achievements in recent years have attracted worldwide attention and have also been established for many cities around the world, especially some cities in developing countries. Set an example and provide experience.
Someone declared on social media a few years ago that they would "escape from Beijing" because of the smog.
However, smog is becoming less and less common in Beijing today.
Liu Baoxian cited a set of data to prove that Beijing's air quality has improved significantly: In 2013, Beijing had no heavy PM2.5 pollution for only 87 consecutive days.
In 2020, Beijing will be free of heavy PM2.5 pollution for 322 consecutive days.
At the same time, the "gold content" of Beijing's blue sky continued to increase. The total number of days with good air quality throughout the year was 276 days, 36 days more than in 2019 and 100 days more than in 2013.
He said that overall, pollution is a major problem that plagues many cities.
For example, it took London 20 years to basically get rid of the "fog city" hat, and it took Los Angeles more than 60 years to improve the photochemical pollution situation. By 2007, it basically reached a relatively good clean air condition.
Liu Baoxian pointed out that from the data point of view, in recent years, through coordinated regional emission reductions, Beijing has made historic progress in improving air quality, which has been highly praised by the whole world, and it is also highly regarded by many cities, especially some cities in developing countries. Set an example and provide experience.
"The pollution we experienced in the past few years is still being experienced in many cities around the world. This problem must be viewed objectively. Air pollution is not unique to us." He said that although the annual average concentration of PM2.5 in Beijing is now 38 micrograms/ However, compared with some international cities, the PM2.5 concentration is still high, and there is still a certain gap between the national air quality standard (35 micrograms/cubic meter), and continuous efforts are still needed.
Liu Baoxian pointed out: We must scientifically recognize the arduousness and long-term nature of air pollution control, and understand the causes of pollution. We don’t want to control it today, but we will manage it tomorrow. It takes some time and we must strengthen our confidence.
