本站 2 月 24 日消息，据生态环境部转央视《新闻联播》报道，我国 2024 年环境空气质量稳中向好，完成大气污染防治年度各项目标任务。
据介绍，2024 年全国环境空气质量改善幅度大，其中：PM2.5 浓度为 29.3 微克 / 立方米，同比下降 2.7%；优良天数比例为 87.2%，同比提高 1.7 个百分点；重度及以上污染天数比例为 0.9%，同比下降 0.7 个百分点。三项约束性指标均优于年度目标。
本站查询获悉，京津冀、天山北坡城市群、成渝地区、汾渭平原、长江中游城市群、长三角地区这六大区域，人口和经济总量占据全国一半以上，PM2.5 浓度同比已分别下降 3.4%、13.4%、10.8%、4.8%、4.4%、0.9%。
生态环境部表示，今年仍将对京津冀及周边地区、汾渭平原、成渝地区等大气污染防治重点区域加大治理力度，力争今年基本消除重污染天气。
