In recent years, the state has paid more and more attention to environmental protection and a series of air pollution prevention and control measures have been effectively implemented. China's air quality has been significantly improved, environmental problems have been gradually reduced, and public health has been effectively guaranteed.

First, the governance results are remarkable

1. the concentration of pm 2.5 has dropped significantly. Since the release of "Ten Atmospheric Articles" in 2013, the average concentration of PM2.5 in cities across the country has dropped from 72 μ g/m3 to 39 μ g/m3 (by the end of 2021), exceeding the planning target, especially in key areas such as Beijing-Tianjin-Hebei and surrounding areas.

2. The proportion of excellent days has steadily increased. Taking Beijing as an example, in 2021, the number of days when air quality reached the standard reached 288, an increase of nearly four months compared with ten years ago; The number of heavily polluted weather dropped sharply from 58 in 2013 to only 8.

3. The rate of ozone exceeding the standard is reduced. On the basis of controlling the emission of volatile organic compounds, ozone pollution has been effectively curbed in summer, the difference between cities has narrowed, and the ozone concentration in cities at prefecture level and above has decreased compared with the same period of last year.

Second, the main initiatives and experiences

1. Strengthen source control. Strict implementation of the coal-fired boiler elimination and transformation plan, promotion of the use of clean energy, strengthening the supervision of motor vehicle exhaust emissions, and prohibiting highly polluting vehicles from entering the city have effectively reduced the total amount of pollutants discharged.

2. Promote the optimization and upgrading of industrial structure. Through policies to guide and support the development and application of green and low-carbon technologies, encourage enterprises to save energy and reduce emissions, promote the transformation and upgrading of traditional industries, and achieve a win-win situation of economic and ecological benefits.

3. Improve the system of laws and regulations. Issue or revise relevant legal documents, clarify the responsibilities and obligations of the government, enterprises and individuals, increase the punishment for illegal sewage discharge, and create a good legal environment.

4. Increase capital investment and technical support. The central government set up special funds to support the prevention and control of air pollution in various places, and organized scientific research institutions to tackle key scientific and technological problems in key areas, providing a solid backing for winning the blue sky defense war.

Third, the future outlook

Although some achievements have been made at present, the ecological environment situation facing China is still severe and complicated, so we must continue to maintain a high-pressure situation and unswervingly promote the construction of ecological civilization. In the next step, we will continue to deepen the structural reform on the supply side, accelerate the formation of a spatial pattern, industrial structure, production methods and lifestyles that save resources and protect the environment, and build a modern governance system so that the people can enjoy more beautiful homes with blue sky and white clouds and green mountains.
