By 2025, PM2 will be achieved in cities at and above the prefecture level across the country5. The concentration will be reduced by 10% compared with 2020, the proportion of days with severe pollution and above will be controlled within 1%, and the total emissions of nitrogen oxides and volatile organic compounds will be reduced by more than 10% compared with 2020. "A few days ago, the "Action Plan for Continuous Improvement of Air Quality" (hereinafter referred to as the "Action Plan") was issued to make a comprehensive deployment for the continuous improvement of air quality. A series of goals, tasks and effective measures demonstrate China's firm determination to continue to fight the battle to defend the blue sky and effectively protect the health of the people.
A good ecological environment is the fairest public good and the most inclusive people's livelihood and well-being. Since the 18th National Congress of the Communist Party of China, the construction of ecological civilization has been placed in a prominent position in the overall work, and the resolute victory in the battle for the blue sky has been taken as the top priority, and the action plan for the prevention and control of air pollution and the three-year action plan for winning the battle for the blue sky have been continuously implemented, and the structure of industry, energy, transportation and land use has been vigorously adjusted and optimized.
The number of coal-fired boilers and kilns nationwide has been reduced from nearly 500,000 to less than 100,000, and the use of coal has been reduced by more than 400 million tons. In the northern region, about 37 million rural households have been treated with loose coal, reducing the consumption of loose coal by more than 70 million tons; 10.300 million kilowatt coal-fired power units have completed ultra-low emission transformation; More than 30 million old and high-emission motor vehicles will be phased out. In 2022, the national PM2The five-year average concentration has historically reached 29 microgram cubic meters, and the proportion of days with good air quality in cities at and above the prefecture level has reached 865%, China has become the country with the fastest improvement rate of air quality in the world, and coal-source pollution has been basically solved. The people's sense of ecological environment gain, happiness and security has been continuously improved.
The results are gratifying, and it should also be noted that the fluctuations in air quality in the northern region in the autumn and winter of this year reflect the long-term and arduous nature of air pollution control. China's air pollution control has entered a critical period of moving forward with heavy loads and climbing over hurdles, and the turning point of air quality from quantitative to qualitative change has not yet arrived, and the overall air quality has not yet been affected by meteorological conditions. Heavy pollution weather is still frequent, and the industrial structure is biased towards chemicals, the energy structure is biased towards coal, and the transportation structure is biased towards highways, which has not been fundamentally improved. Only by studying new situations and solving new problems in a timely manner can we continue to fight the battle for blue skies and promote continuous improvement of air quality.
On the basis of summarizing the air pollution control work in the past 10 years, the Action Plan clarifies the future improvement goals, work priorities, and action measures, with improving air quality as the core, reducing heavily polluted weather and solving outstanding atmospheric environmental problems around the people as the focus, so as to reduce PM25. With concentration as the main line, we will vigorously promote the emission reduction of nitrogen oxides and volatile organic compounds, promote carbon reduction, pollution reduction, green expansion and growth, and solidly promote the green and low-carbon transformation of industry, energy and transportation, so as to achieve a win-win situation of environmental, economic and social benefits.
The Action Plan optimizes and adjusts the key areas of air pollution prevention and control, and puts forward improvement goals. Place PM25. Cities in the southeastern part of Shandong and central and southern Henan with high concentrations were included in the Beijing-Tianjin-Hebei region and its surrounding areas, and the adjusted Beijing-Tianjin-Hebei region and its surrounding areas changed from "2+26" cities to "2+36" cities; Place PM25. Some cities in southern Zhejiang and southern Anhui, where the concentration is basically stable and up to the standard and have a small contribution to pollution in the Yangtze River Delta region, will be transferred out, highlighting key points and making precise efforts. The Action Plan deploys 9 key tasks, involving industrial structure, energy structure, transportation structure, non-point source pollution control, etc., one of the highlights is to highlight the green and low-carbon transformation of transportation, and put forward a number of quantitative indicators, such as by 2025, the railway and waterway freight volume will increase by about 10% and 12% respectively compared with 2020; For airports with an annual passenger throughput of more than 5 million passengers, the utilization rate of bridge power has reached more than 95%.
On the new journey, we must continue to fight the tough battle of pollution prevention and control, adhere to precise pollution control, scientific pollution control, and pollution control in accordance with the law, maintain strength, extend the depth, and expand the breadth, and further promote the three major defense battles of blue sky, clear water, and pure land, and continue to improve the quality of the ecological environment. By firmly establishing and practicing the concept that lucid waters and lush mountains are invaluable assets, synergistically promoting carbon reduction, pollution reduction, green expansion and growth, and continuing to fight the battle to defend the blue sky, we will be able to promote high-quality development and create a high-quality life with high-level protection of the ecological environment.
