“十四五”时期蓝天保卫战取得历史性成就

Core Viewpoint - The Ministry of Ecology and Environment announced that by 2025, China's air quality will reach its best level in history, achieving a significant milestone in the Blue Sky Defense War and laying a solid foundation for the construction of a beautiful China [1]. Group 1: National Air Quality Improvement - By 2025, the average PM2.5 concentration in cities at or above the prefecture level will reach 28.0 micrograms per cubic meter, with a good air quality day ratio of 89.3% (excluding dust influence) and heavy pollution days at only 0.9% [1]. - From July 20 to October 24, 2025, the proportion of good air quality days maintained above 90% for the first time, marking a historic breakthrough [1]. - Compared to 2020, the concentrations of five major pollutants, including sulfur dioxide and nitrogen oxides, will decrease by 15%-20% by 2025, while ozone levels will stabilize [1]. Group 2: Regional Governance Achievements - The PM2.5 average concentration in the Beijing-Tianjin-Hebei region and the Fenwei Plain decreased by 27.7% and 32.1%, respectively, contributing nearly 50% of the national air quality improvement despite representing less than one-sixth of the total cities [2]. - Linfen, Shanxi, achieved the highest improvement, with PM2.5 concentration dropping by 46.5% compared to 2020 [2]. - During the 14th Five-Year Plan, GDP increased by 30% while PM2.5 concentration decreased by 20%, with the number of cities meeting air quality standards rising from 206 to 246 [2]. Group 3: Key Measures for Air Quality Improvement - The three-pronged approach of "transformation, reduction, and treatment" has been crucial for achieving historical results in the Blue Sky Defense War [3]. - Structural optimization focuses on industries, energy, and transportation, with significant capacity reductions, including the elimination of 12 million tons of sintering capacity and 6.826 million tons of small coke oven capacity [3]. - Pollution control has been deepened, with 9.4 billion tons of crude steel and 3.6 billion tons of coking capacity undergoing ultra-low emission transformations [3]. - Regulatory capabilities have been enhanced through revised air quality standards and the establishment of a comprehensive monitoring network [3].
