守护美丽蓝天，我国部署修订环境空气质量标准

Core Viewpoint - The State Council's meeting on February 6 announced the revision of the "Ambient Air Quality Standards," setting higher targets for annual PM2.5 concentration levels to further improve air quality in China [1][2]. Group 1: Air Quality Improvement - Under the current air quality standards, China's air quality has significantly improved, with the national average PM2.5 concentration projected to be 28 micrograms per cubic meter by 2025, a year-on-year decrease of 4.4% [1]. - The proportion of days with good air quality is expected to reach 89.3% by 2025, an increase of 1.9 percentage points year-on-year [1]. - During the "14th Five-Year Plan" period, the cumulative reduction in PM2.5 concentration is targeted at 20%, with the best levels of good air quality days recorded since monitoring began, and a 25% reduction in heavy pollution days [1]. Group 2: Policy and Implementation - The revision aims to enhance the guiding role of air quality standards, focusing on the continuous reduction of PM2.5 concentrations and promoting structural optimization and refined pollution control [1][2]. - The Ministry of Ecology and Environment emphasizes the need for a smooth transition while ensuring stable economic and social operations, with gradual implementation of supporting policies, funding, and technical methods for air quality compliance [2]. - The revised standards will establish reasonable limit values and create a scientific framework to improve air management and pollution control effectiveness [2].
