2026年2月24日晚，生态环境部联合国家市场监管总局发布新版《环境空气质量标准》（GB 3095-2026）（简称《标 准》），新标准收严了PM2.5年均和日均浓度限值，同时明确将按照两阶段实施，自2031年起全面执行修订后的颗粒物 和二氧化硫、二氧化氮等污染物浓度限值。 现行《标准》（ GB 3095-2012）自2012年发布实施，由此开启了我国大气污染防治的新阶段——这是我国首次将PM2.5 纳入常规监测指标，为全国 "蓝天保卫战" 划定了明确目标。 在现行标准推动下，我国空气质量显著改善。2025年，全国PM2.5平均浓度降至28微克/立方米，同比下降4.4%；优良 天数比例达89.3%，同比上升1.9个百分点。"十四五"期间，全国PM2.5浓度累计下降20%，优良天数比例创有监测以来 最好水平，重污染天数减少25%。我国成为全球空气质量改善速度最快的国家。 不过，生态环境部大气环境司有关负责人指出，国内外研究成果都表明，PM2.5是全球空气污染疾病负担的最大驱动因 素；世界卫生组织于2021年更新《全球空气质量指南》，进一步加严了PM2.5年均浓度指导值。2025年，全国仍有约六 成的城市PM2. ...

2月24日晚，生态环境部发布《环境空气质量标准》（GB 3095—2026）（以下简称《标准》）。记者注意到，在 上一版《环境空气质量标准》中，细颗粒物（PM2.5）年均浓度二级限值为35微克/立方米。新版《标准》将这一 限值调整为25微克/立方米，2026年3月1日起至2030年12月31日，执行过渡阶段浓度限值，即30微克/立方米。 新版《标准》调整了PM2.5等污染物的浓度限制。图/生态环境部微信公众号 提高浓度限值要求，逐步接轨国际先进水平 生态环境部大气环境司有关负责人表示，党的十八大以来，我国在经济高速发展的同时，PM2.5年均浓度从2013 年的68微克/立方米下降到2025年的28微克/立方米，成为全球空气质量改善速度最快的国家。上一版《标准》于 2012年发布，自实施以来，对我国持续深入打好蓝天保卫战、保障人民群众身体健康发挥了重要引领作用。 党的二十届四中全会将美丽中国建设取得新的重大进展作为"十五五"时期经济社会发展的主要目标之一。此时修 订《标准》，一是进一步保障人民群众身体健康。国内外研究成果都表明，PM2.5是全球空气污染疾病负担的最 大驱动因素；世界卫生组织于2021年更新《全球 ...

Core Viewpoint - The Ministry of Ecology and Environment and the State Administration for Market Regulation have jointly released revised air quality standards, tightening the concentration limits for particulate matter and its precursors to better protect public health [1][2]. Group 1: Revised Standards - The new standards set the annual PM2.5 concentration limit to 10 micrograms per cubic meter for Level 1 and 25 micrograms per cubic meter for Level 2, with daily limits of 25 and 50 micrograms per cubic meter respectively [1]. - The previous standards were established in 2012, and the new revisions reflect a significant tightening of limits for PM10, sulfur dioxide (SO2), and nitrogen dioxide (NO2) [1]. Group 2: Implementation Phases - The standards will be implemented in two phases: the first phase from March 1, 2026, to December 31, 2030, will have transitional concentration limits for PM2.5 and PM10 [2]. - The second phase, starting January 1, 2031, will enforce the revised concentration limits nationwide [2]. Group 3: Expected Impacts and Benefits - The revision is expected to lead to a decrease in the proportion of cities meeting air quality standards, but this does not indicate a deterioration in air quality; rather, it reflects the higher standards being set [3]. - The implementation of the new standards is anticipated to drive a continuous decline in PM2.5 levels, reducing health risks, particularly for vulnerable populations [3]. - The standards are projected to facilitate the development of clean energy and new energy vehicles, promoting a green and low-carbon transition in key industries, with an expected reduction of over 7 billion tons of carbon dioxide from 2026 to 2035 [3].
