US media: China's 7 -year decreased air pollution is as much as the United States decreased in 30 years.

An article on June 14, Bloomberg, USA. Original topic: China's 7 -year decreased air pollution is as reduced as the United States decreased in 30 years. China has decreased in 7 years. Help reduce the global smog level. Data from the Institute of Energy Policy at the University of Chicago showed that from 2013 to 2020, the concentration of harmful suspended particles in Chinese air decreased by 40%. If this trend continues, the average life expectancy of people will increase by about two years.

In a report released on Tuesday (14th), researchers said that about 97%of the world's population lived in areas where air quality is usually lower than that of the World Health Organization Guide. They said that haze can reduce the life expectancy of the world's per capita per capita compared to poor smoking, alcoholism or poor hygiene conditions. "China's success in reducing pollution shows the opportunities in front of other countries. As long as they implement a strong pollution policies, as some countries are starting to do it."

The World Health Organization raised the relevant standards last year. Even if it has been struggling with pollution for decades, and only the United States and Europe, which accounts for 4.1%of the health burden of global air suspended particles, there are still more than 90%of people living in the lives that do not meet the WHO of WHO. Area of ​​organizational guidelines.

Researchers said in emails that China has achieved rapid success in restrictions on car use and coal -fired in major cities. Within 7 years, the degree of air pollution in its territory is 40%, which is almost equivalent to the United States since 1970 through a milestone "Cleaning Clean The Aerial Act "Achievement" has achieved more than 30 years of achievements -reduced by 44%.

Researchers said that without the decrease in China's air pollution, the world's average level of air pollution will rise further since 2013, rather than decline. This is because countries in South Asia, Southeast Asia, and Central Africa are realizing industrialization and the quality of air continues to deteriorate.

In 2020, nearly half of the global air pollution increased from India, and its PM2.5 concentration rose by 2.9%. The PM2.5 concentration of Pakistan rose 6.3%, the PM2.5 concentration of Bangladesh rose 13%, and the local PM2.5 concentration was equivalent to 15 times that of the World Health Organization Guide.

Knita Harson Copher, the co -author of the study and the director of the air quality project of the University of Chicago, said, "Air pollution is indeed a disease and requires decades of investment to make practical progress." Ram et al., Wang Huicong translated)
