On February 27, the Ministry of Ecology and Environment held a regular press conference in February. Li Tianwei, Director of the Department of Atmospheric Environment of the Ministry of Ecological Environment, attended the conference to introduce the situation of "fighting the battle of defending the blue sky in depth and promoting the construction of beautiful blue sky in an all-round way". At
the press conference
, Li Tianwei, director of the Department of Atmospheric Environment of the Ministry of Ecology and Environment, said that
air quality is an indicator of people's livelihood that people can feel. Beautiful China is a living room, beautiful blue sky is the background board, blue sky and white clouds do not need to make an appointment, anytime, anywhere, and do not need to deliberately look up to meet. Super beautiful, we have reason to believe in beauty forever.
2025 is the closing year of the 14th Five-Year Plan, and the node is the test point. How about the air pollution prevention and control work in the 14th Five-Year Plan and 2025? I think we should look at the report card first. Measure and evaluate it from three aspects.
From the national level, the air quality is the best in history. In 2025, the three national assessment indicators have achieved the best level since the monitoring records. The average concentration of PM2.5 in cities at prefecture level and above has reached 28.0 micrograms/cubic meters, the proportion of good days has reached 89.3% (excluding the impact of sand and dust), and the proportion of heavy pollution days is 0.9%, which is a very impressive achievement. Especially from July 20 to October 24, 2025, the proportion of good days in the whole country is more than 90% for 97 consecutive days for the first time. The blue sky is often there, and there are surprises every day, which is not easy. Over the past five years, six pollutants, sulfur dioxide, nitrogen oxides, carbon monoxide, ozone, PM2.5 and PM10, have been reduced by about 15% -20% in 2025 compared with 2020, and all of them are the best in history. Only one is the concentration of ozone, which in 2025 has been basically the same as that in the early period of the 14th Five-Year Plan, and has curbed the continuous upward trend, which is the first level.
The second level, from the regional level, the key areas have improved significantly. During the "14th Five-Year Plan" period, China's air quality was generally "good in the south and greatly improved in the north". In 2025, 7 of the 10 provinces with the lowest PM2.5 concentration were in the south, and the 10 provinces with the greatest improvement were all in the north. In particular, the average concentration of PM2.5 in Beijing-Tianjin-Hebei and surrounding areas and Fenwei Plain decreased by 27.7% and 32.1% respectively, reaching 37.3 micrograms/cubic meters and 33.7 micrograms/cubic meters respectively; Although the number of cities in these two regions is less than 1/6 of the national cities, the two regions add up to 51 cities at prefecture level and above, but the contribution to the improvement of air quality in the country is nearly 50%, and the 20 cities with the largest improvement of PM2.5 concentration are almost all in these two regions, which are the driving force and ballast stone for the improvement of air quality in the country. Let me briefly point out that Linfen, Shanxi Province, has made the greatest improvement. In 2025, the average concentration of PM2.5 in Linfen was 35.1 micrograms/cubic meters, which was 30.5 micrograms/cubic meters lower than that in 2020, a decrease of 46.5%, and the improvement rate was the first in the country. Since the 14th Five-Year Plan, Linfen has shut down and withdrawn 9.15 million tons of coking capacity, 220000 tons of crude steel capacity, 100% of advanced capacity in coking, ironmaking, steelmaking and other industries, and 143 enterprises in seven provincial industrial parks have basically completed the transformation of clean transportation. Thermal power, iron and steel, coking, coal, non-ferrous metals, cement and other six major industries accounted for more than 85% of the clean transportation of bulk goods, and 10 iron and steel, 7 coking and 16 cement enterprises in the city completed ultra-low emission transformation. This is a great achievement and a great achievement.
Thirdly, from the perspective of the relationship between development and improvement, economic development and air quality improvement have achieved a "win-win" situation, and air quality improvement is not a stumbling block to economic development. During the 14th Five-Year Plan period, China's GDP increased by 30%, PM2.5 concentration decreased by 20%, and the number of cities with air quality standards increased from 206 to 246, an increase of 20%. In 2025, the average concentration of PM2.5 in 29 cities with GDP exceeding trillion yuan was 27.8 micrograms per cubic meter, which was not only better than national average, but also improved significantly during the 14th Five-Year Plan period. These tangible governance results show that economic development and the protection of the blue sky can be coordinated and win-win. Especially in Beijing, after 12 years of hard work, the average concentration of PM2.5 dropped from 89.5 micrograms/cubic meters in 2013 to 58 micrograms/cubic meters in 2017, and further to 27 micrograms/cubic meters in 2025, achieving "breaking 60 into 30", from "APEC blue", "Winter Olympic blue" to "normal blue". Three hundred and sixty is an old thing, and the blue sky often accompanies Yanjing. Beijing's air quality improvement is a landmark achievement in China's air pollution prevention and control.
But what I want to say is that there is no blue under the sky. The historic achievements of the Blue Sky Defense War during the 14th Five-Year Plan period lie in the personal planning, deployment and promotion of the General Secretary of Xi Jinping, in the scientific guidance of Xi Jinping Thought on Socialism with Chinese Characteristics for a New Era, especially the ecological civilization thought of Xi Jinping, and in the joint efforts and United struggle of all regions and departments. It is also inseparable from the hard work and hard work of the National Iron Army for Air Pollution Prevention and Control. Over the past five years, we have resolutely shouldered the political responsibility of "the most important thing in the battle of defending the blue sky and fighting hard battles", devoted ourselves to improving, promoting emission reduction scientifically and accurately, planning and promoting the work of defending the blue sky with a higher position, a broader vision and greater efforts, and comprehensively promoting the construction of a beautiful blue sky.
To sum up, we can use three words, the first word is "turn", and the pace of "turn" continues to accelerate. We should persist in supporting high-quality development with high-level protection, focus on the optimization and adjustment of the three major structures of industry, energy and transportation, and improve air quality from the source. We will accelerate the upgrading of key industries and eliminate 120 million tons of stepping sintering machines and 68.26 million tons of coke ovens with a capacity of 4.3 meters or less. Gas-related production capacity and equipment to be eliminated in key areas will be basically eliminated, and the proportion of advanced equipment production capacity in sintering, ironmaking and coking will be increased by 17, 25 and 22 percentage points respectively. We will promote clean and low-carbon energy utilization, shut down and integrate 30000 scattered and inefficient coal-fired boilers, and basically eliminate coal-fired boilers with 35 steam tons or less in key areas; Transportation has become green and new, nearly 30 million high-emission old vehicles have been eliminated, the market penetration rate of new energy vehicles has exceeded 50%, and the production and sales volume has ranked first in the world for 11 consecutive years.
The second word is "reduction", and the space for "reduction" is effectively expanded. Deeply implement source emission reduction, functional emission reduction and system emission reduction, and promote coordinated emission reduction of volatile organic compounds, nitrogen oxides and other pollutants. We will promote in-depth treatment of key industries with high quality, complete the transformation of 940 million tons of crude steel, 360 million tons of coking, 470 million tons of cement clinker production capacity and 170 million kilowatts of coal-fired power units with ultra-low emissions, and greatly reduce pollutant emissions. Vigorously promoting industrial transformation and upgrading; actively and steadily promoting the transformation of clean heating in the northern region, completing the treatment of 17 million tons of loose coal, the clean heating rate in the northern region reached 83%, and basically eliminating loose coal in key regions and plains; Efforts should be made to promote the whole chain management and control of VOCs, packaging and printing of paper products, basically realize the substitution of low VOCs raw materials in the automobile manufacturing industry, investigate and rectify 138000 outstanding VOCs problems, increase the proportion of efficient treatment facilities in key pollutant discharge units by 9 percentage points, and build 142 "green islands" of VOCs to achieve centralized and efficient treatment.
The third word is "governance", and the ability of "governance" has been significantly improved. Comprehensive use of administrative, legal, market, science and technology and other means to continuously improve the energy efficiency of air pollution control. We formulated and revised 11 emission standards for stationary sources and 2 emission standards for mobile sources, and gradually established a scientific and systematic air pollutant emission standard system; we promoted the gradual extension and expansion of regional joint prevention and control mechanisms from key regions to non-key regions, and established regional linkage mechanisms in eight major regions of the country; The integrated perception network of space, earth and air has been built in an all-round way, three special satellites for atmospheric environmental monitoring have been launched, 1734 state-controlled air quality stations have been set up, and more than 12000 local monitoring stations have been networked, which provides a solid data support for precise pollution control; Innovation of off-site law enforcement supervision mode, optimization of 48 kinds of problem clue analysis models in seven scenarios, so as to take clues, aim at problem investigation, focus on problem correction, promote the number of on-site inspections nationwide to decrease by 40% -60%, but the rate of problem discovery has increased by 10-25 percentage points, basically achieving law enforcement supervision without disturbance, everywhere and impeccable.
I understand that the improvement of air quality is a long March for the governance of China's ecological environment. Our generation of atmospheric people should strive to take their own long March, so that the blue sky and white clouds become the background of a happy life. This year is the first year of the Fifteenth Five-Year Plan. We will further study and implement the new deployment and requirements of the Fourth Plenary Session of the Twentieth Central Committee of the Communist Party of China, adhere to environmental protection for the people, take the new air quality standards as the guide, take the reduction of PM2.5 concentration as the main line, vigorously promote the transformation and upgrading of energy industry and transportation structure, and constantly strengthen air pollution. Promote the overall improvement of air quality, benefit the general public with more blue sky and white clouds, and build a more solid foundation for the beautiful blue sky in the construction of beautiful China.
