近期，生态环境部发布了《环境空气质量标准（征求意见稿）》，修订稿加严了PM2.5和PM10、SO2、 NO2等污染物浓度限值。 从长期来看，加严标准不但有助于推动PM2.5浓度的进一步降低，促进空气质量改善，有效减少心血管 疾病、呼吸系统疾病的急性发病和住院风险，带来显著的公共健康收益，增进民生福祉；而且能够有效 带动新能源汽车、清洁能源等新质生产力的培育与发展，促进冶金、建材、石化等行业先进工艺的推广 使用，推动产业、能源、交通运输结构绿色低碳转型，促进经济社会高质量发展。 通过实施相对严格的空气质量标准，我国引领大气污染防治工作实现了四个战略性转变：由污染物排放 总量控制向空气质量改善转变、由单一污染物向多污染物协同控制转变、由工业源向多种污染源综合治 理转变、由局地污染控制向区域联防联控转变。国内外经验表明，相对严格的标准，不仅引领空气质量 改善，更好保护人民群众身体健康，也为经济发展注入绿色动能，推动经济社会高质量发展。 标准修订对经济社会发展正面推动作用更加明显 修订后的《环境空气质量标准》按照两阶段实施。其中，第一阶段为2026-2030年，执行颗粒物浓度过 渡限值。即PM2.5年均和日均浓度二级 ...

生态环境部近期发布的《环境空气质量标准(征求意见稿)》，收严了PM2.5等多项污染物浓度限值。收 严标准是否会对经济社会发展产生不利影响？这一标准与发达国家和地区相比如何？生态环境部新闻发 言人裴晓菲26日进行了回应。 在生态环境部当天举行的新闻发布会上，裴晓菲介绍，现行环境空气质量标准2012年发布。从实践经验 看，标准修订不仅极大地改善了全国空气质量，而且对经济高质量发展发挥了积极的促进作用。与2015 年相比，十年来全国PM2.5平均浓度下降了36%，重污染天数减少了68%，但国内生产总值上升63%、 汽车保有量增长111%。 他介绍，通过实施相对严格的空气质量标准，引领我国大气污染防治工作实现了四个转变：由污染物排 放总量控制向空气质量改善转变、由单一污染物向多污染物协同控制转变、由工业源向多种污染源综合 治理转变、由局地污染控制向区域联防联控转变。 近年来，美国、欧盟、日本、韩国等多个国家和地区分别修订了PM2.5浓度限值，比如2024年美国环保 署将PM2.5年均值从12微克/立方米收紧到9微克/立方米，与之相比，我国的PM2.5年均浓度二级限值仍 偏宽松。 根据征求意见稿，本次修订将PM2.5年 ...
