沈阳如何实现“蓝天逆袭”？

Core Viewpoint - Shenyang has successfully improved its air quality over the past decade, achieving a record high of 318 days of good air quality in 2024, marking a 9.8% improvement year-on-year, and has not experienced heavy pollution during the heating season from November 2024 to March 2025 [1][2]. Group 1: Air Quality Improvement - In 2025, Shenyang recorded 245 days of good air quality in the first three quarters, an increase of 17 days compared to the previous year, with PM2.5 average concentration dropping to 31.1 micrograms per cubic meter [1]. - The city has implemented a series of measures to tackle air pollution, focusing on heating, transportation, and industrial sectors, leading to significant improvements in air quality [3][4]. Group 2: Structural Adjustments - Shenyang faced three inherent challenges in air quality management: reliance on heavy industry, high logistics vehicle concentration due to its transportation hub status, and significant coal demand during the heating season [3]. - The city has initiated a "boiler rectification campaign," removing approximately 4,000 boilers and upgrading remaining coal-fired boilers to meet stricter emission standards [4][5]. Group 3: Mobile Source Pollution Control - The city has identified that vehicle emissions are a major source of air pollution, with a significant number of older vehicles still in use, necessitating enhanced regulatory measures [6][7]. - In 2024, Shenyang successfully eliminated over 30,000 old diesel trucks and updated 82,400 vehicles to meet higher emission standards [7][8]. Group 4: Industrial Upgrades and Technological Empowerment - Shenyang is focusing on upgrading its industrial structure, with a notable increase in green factories and a commitment to reducing volatile organic compounds (VOCs) emissions through targeted strategies [9][10]. - The city has invested in advanced air quality monitoring systems, including a comprehensive pollution monitoring network and a high-tech monitoring station to provide real-time data for pollution management [10][11]. Group 5: Collaborative Governance - Shenyang is expanding its air quality management efforts beyond city limits by collaborating with surrounding cities to implement joint pollution control measures [11].
