2025年，北京率先交出空气质量答卷，PM2.5年均浓度达到27.0微克/立方米，首次“破30”，空气质量优良天比率首次超八成，重污染日基本消除。北京取得这样的成绩有多不容易？全国其他地区这一年来空气质量如何？#蔚蓝地图# 为您逐小时盘点。

As the new year begins, Beijing has already delivered its 2024 "Blue Sky Defense" results. The annual PM2.5 concentration stood at 30.5 μg/m3, a 6.2% drop from last year. For the fourth year in a row, Beijing has met the national air quality Grade II standard, with 290 days of good and moderate air quality — the highest on record. How did Beijing achieve this? How did other cities perform? Find out in #BlueMap Air Quality Dynamics.

Following the release of the Air Pollution Prevention and Control Action Plan in 2013 and the Three-Year Action Plan for Winning the Blue Sky Defense Battle in 2018, the third "Air Ten Measures", the Action Plan for Continuous Improvement of Air Quality (hereinafter referred to as the "Action Plan") has recently been issued. The "Action Plan" aims to drive high-quality economic development through continuous improvements in air quality. Based on the current status of air quality improvements and atmospheric transmission characteristics, the "Action Plan" has adjusted the key areas for air pollution control to 82 cities. How do these changes in the key areas for pollution control compare to those in the Three-Year Action Plan for Winning the Blue Sky Defense Battle?

The year 2023 saw a transition in climate cycles, overall unfavorable meteorological conditions, and frequent sandstorm events, coupled with the post-pandemic recovery of social and economic activities. Despite these challenges, maintaining steady improvements in air quality was an extraordinary achievement. China’s air pollution control has entered a critical phase. Sustaining improvements in air quality requires a coordinated approach between carbon reduction, pollution control, and high-quality development.
