精抓细抠到0.1微克 北京“抠”出常态蓝

Core Viewpoint - Beijing has achieved significant improvements in air quality by 2025, with PM2.5 annual average concentration dropping to 27 micrograms per cubic meter, marking a milestone in air pollution control efforts [3][4][6]. Group 1: Air Quality Improvements - The annual average concentration of PM2.5 in Beijing decreased by 11.5% compared to the previous year, achieving a level below 30 micrograms for the first time [3][4]. - The number of days with good air quality reached 311, an increase of 21 days year-on-year, resulting in a good air quality rate of 85.2% [3][4]. - The number of heavy pollution days was reduced to 1, the lowest since monitoring began, down from 58 days in 2013, representing a reduction of 98.3% [4][6]. Group 2: Pollution Reduction Metrics - Major pollutants saw significant reductions: PM2.5 down 69.8%, PM10 down 55.6%, NO2 down 60.7%, and SO2 down 84.9% from 2013 levels [4][6]. - PM2.5 good air quality days increased from 55.9% in 2013 to 95.3% in 2025, with a notable stretch of 227 consecutive days of good PM2.5 levels from March to October 2025 [4][6]. Group 3: Strategies and Technologies - Beijing's air quality improvement is attributed to precise pollution control measures, including the "1 microgram" and "0.1 microgram" action plans, focusing on meticulous pollution source management [6][7]. - The city has implemented a comprehensive air quality monitoring network, integrating data from various sources to enhance pollution tracking and response capabilities [7][10]. - Local emission reductions contributed over 50% to air quality improvements, with regional cooperation accounting for 30%-40% of the progress [8][9]. Group 4: Future Challenges and Goals - Future air quality management will face challenges due to weather variability, necessitating continued efforts in emission reductions and technological advancements [10][12]. - The revised air quality standards set for 2026-2030 will require PM2.5 annual and daily limits of 30 and 60 micrograms per cubic meter, respectively, pushing for further improvements [11][12]. - The goal is to transition from "luxury blue skies" to "everyday blue skies," aiming for air quality to become a standard aspect of daily life [11][12].
