Introduction: Since the initial treatment of air pollution, China ’s air quality has continued to improve, and PM2.5 in the three regions with more concentrated and severe pollution has also declined significantly. 2019 is the year of tackling the challenge of defending the blue sky. The three major regions have successively introduced a number of policies. What are they?
Since the 1970s, China has begun to notice the treatment of air pollution, which has gone through five stages. Starting from a single target for a certain air pollutant, a joint prevention and control, multi-pronged governance situation has been formed, and air quality has also been significantly improved.
According to data released by the Ministry of Ecology and Environment, from January to November 2019, the PM2.5 concentration in 337 prefecture-level cities and above was 34 micrograms per cubic meter, a year-on-year decrease of 2.9%. The air pollution control in the three key areas of the Beijing-Tianjin-Hebei, Fenwei Plain and the Yangtze River Delta has also achieved good results.
From the monthly air quality situation in 2019, most of the PM2.5 concentrations in the three major regions are in a downward trend. The details are as follows:

This is due to the efforts made by the three major regions in the treatment of air pollution in 2019, from the aspects of industry, energy, transportation and agriculture to coordinated management. According to their own characteristics, corresponding policies and regulations have been issued to suit local conditions. Targeted pollution control strategies and strict pollution control methods ensure continuous improvement of air quality.
What are the specific policies? The editor of Environmental Protection Online compiled this, the details are as follows:

At present, the prevention and control of atmospheric pollution in autumn and winter is in progress. According to the requirements, during the autumn and winter of 2019-2020, the average concentration of PM2.5 in Beijing-Tianjin-Hebei and its surrounding areas decreased by 4%, and the average concentration of Fenwei Plain decreased by 3%. The average concentration in the triangle area decreased by 2%. In the face of complex and unstable atmospheric governance, the governance tasks of the three key areas are still arduous.
2020 is the final year of the three-year blue sky defense war. Among them, the Beijing-Tianjin-Hebei, Fenwei Plain, and the Yangtze River Delta are the "main positions" to win the blue sky defense war. The goal is set to 2020, PM2.5 is not up to standard The concentration of cities at the prefecture level and above has decreased by more than 18% compared with 2015, and the ratio of days with good air quality has reached 80%.
In addition, it has also eliminated aspects such as overcapacity, rectified "scattered pollution" enterprises, promoted VOCs governance, promoted clean heating, reduced coal consumption, carried out coal-fired boiler rectification, accelerated the application of new energy vehicles, and transformed "transit to iron". Both have put forward requirements. With the continued defense of the blue sky, the three major regions have implemented control measures, and the continuous improvement of the atmospheric environment is a great proof.
Let's wait and see if new breakthroughs can be made in air quality in the three key areas in 2020!
