2025年北京机动车结构达到全国最优

Core Viewpoint - By 2025, Beijing's air quality is expected to reach optimal levels, with PM2.5 annual average concentration dropping to 27.0 micrograms per cubic meter, marking a significant milestone in air pollution control efforts [1][4]. Air Quality Improvement - The annual average concentration of PM2.5 in Beijing is projected to be 27.0 micrograms per cubic meter in 2025, a year-on-year decrease of 11.5%, and the first time it falls below 30 micrograms [4]. - The number of days with good air quality is expected to reach 348 in 2025, an increase of 144 days compared to 2013, with the good air quality rate rising from 55.9% in 2013 to 95.3% in 2025 [4][6]. - From 2013 to 2025, PM2.5 levels have decreased by 69.8%, from 89.5 micrograms per cubic meter to 27.0 micrograms per cubic meter [4][6]. Pollution Reduction Metrics - In 2025, Beijing is expected to have only one heavy pollution day, a reduction of one day from the previous year, marking the lowest number of heavy pollution days recorded [6]. - Other major pollutants, including PM10, NO2, and O3, are also expected to show improvements, with annual average concentrations of 48, 22, and 159 micrograms per cubic meter, respectively, reflecting year-on-year decreases of 11.1%, 8.3%, and 7.0% [6]. - The annual average concentrations of PM2.5, PM10, NO2, and SO2 are projected to decrease by 69.8%, 55.6%, 60.7%, and 84.9%, respectively, compared to 2013 levels [6]. Vehicle Structure Optimization - By 2025, over 60% of new vehicles in Beijing are expected to be new energy vehicles, with the total number of new energy vehicles exceeding 1.28 million, three times the number at the end of the 13th Five-Year Plan [7]. - The proportion of new energy and National V and above vehicles is anticipated to exceed 80%, achieving the best vehicle structure in the country [7]. - The average road dust load in Beijing is projected to be 0.35 grams per square meter, a 40.7% reduction from 2020 levels [7]. Technological Advancements in Monitoring - Beijing is enhancing its air quality monitoring through digital and intelligent regulatory measures, creating a new generation of air quality monitoring network with high precision in problem identification [7]. - The monitoring system is designed to provide real-time data with a recognition accuracy of 90%, significantly improving the city's ability to manage air quality [7].
