Group 1: Core Concept - The construction of "waste-free cities" is a significant initiative to establish a "waste-free" philosophy, cultivate "waste-free" habits, and engage society in solid waste management [1] Group 2: Progress and Innovations - Over 200 cities in China have initiated "waste-free city" construction, transitioning from pilot projects to nationwide implementation [2] - The Chengdu-Chongqing region has signed a cooperation agreement to establish a "waste-free city" collaborative mechanism by 2025, aiming to enhance solid waste management capabilities [2] - The Ministry of Ecology and Environment has established a coordination mechanism involving 17 departments to promote resource integration for "waste-free city" construction [2][3] Group 3: Best Practices and Case Studies - More than 500 best practices have been summarized across various sectors, including industrial, agricultural, and construction waste management [3] - In Ordos, Inner Mongolia, the comprehensive utilization rate of industrial solid waste increased from 37% to 71% through ecological restoration projects [3] - Changzhou, Jiangsu Province, achieved over 99% resource utilization of construction waste through a combination of fixed and mobile processing methods [3] Group 4: Corporate Involvement - Companies are increasingly participating in green transformation and "waste-free city" initiatives, focusing on reducing waste and enhancing resource utilization [4] - Mengniu Group is actively pursuing green packaging strategies to align with international standards and reduce environmental pollution [4][5] Group 5: Community Engagement and Public Participation - Public engagement in "waste-free" initiatives is growing, with various programs and platforms established to facilitate recycling and waste reduction [6] - The "Green Printing Action" project in Zhuhai aims to integrate the waste-free concept into industry and community governance [5][6] - Volunteer initiatives in Shandong have mobilized over 1,000 volunteers, engaging millions in waste reduction activities [6] Group 6: Events and Media Role - Major events like the Asian Games in Hangzhou have incorporated "waste-free" principles, showcasing innovative waste management practices [7] - Media plays a crucial role in promoting the "waste-free" concept and supporting environmental governance efforts [7]

今年5月1日，新修订的《检验检测机构监督管理办法》正式实施，要求检验检测机构应当落实主体责 任，明确了包括授权签字人在内的管理人员职责，以规范检验检测从业人员的行为。 对此，笔者建议各地应进一步优化能力考核方式，将实际操作纳入考核内容，培养一批既懂理论又会操 作的授权签字人，切实承担起机动车尾气排放检验报告的"最终把关人"的责任。 近日，笔者在多家机动车检验机构开展执法检查时发现，原本很少在检测车间出现的授权签字人纷纷现 身尾气排放检测线，亲自进行尾气排放检验操作。问其原因，根据日前市场监管总局联合生态环境部印 发的《机动车检验机构排放检验设备和人员能力现场评审指导书》，在对机动车排放检验机构进行资质 认定评审，要对授权签字人进行操作技能考核。根据考核要求，授权签字人应至少随机挑选一辆汽、柴 油车对外观检验、OBD检查以及排气污染物检测等三项进行实际操作演示。 机动车排放检测机构授权签字人是检测报告的最终审核签发者，一旦签字就意味着检测报告具有了相应 的法律效力，同时也意味着授权签字人从签字的那一刻起就需要对检测报告的真实性承担相应的法律责 任。从各地近年通报的机动车排放检测机构弄虚作假典型案例来看，检测报告 ...

Core Viewpoint - The implementation of the "Small, Fast, and Flexible" legislation, exemplified by the "Hunan Province Noise Pollution Prevention Regulations," aims to address specific, frequently occurring issues in social management, enhancing local governance efficiency [1][2].

冬雪为大地披上静谧的盛装，却也给市民出行、城市交通带来诸多不便。为此，不少地方将"雪停路 净"确定为治理目标。笔者认为，在保障城市安全运行的基础上，可以适度保留一些雪景，让更多人能 够亲近冰雪，感受冬日之美。 冬雪是滋养万物的天然馈赠。于农业而言，"冬日麦盖三层被，来年枕着馒头睡"的农谚流传已久，积雪 如同松软的保温屏障，能为小麦等越冬农作物锁住地温，有效减轻冻害对农作物根系的影响；融雪时的 持续低温，还能冻死土壤表层的害虫卵与致病菌，为来年春耕生产和粮食丰收筑牢基础。于生态而言， 雪水中含有的天然氮化物融化后可成为土壤有机肥料，其疏松的堆积结构能减少土壤水分蒸发、庇护土 壤微生物群落，缓慢消融的过程则能循序渐进润泽春泥、补给地下水。 雪花飘落的过程中，还能高效吸附空气中的PM2.5、扬尘等污染物，低温环境更能抑制细菌、病毒等有 害微生物的繁殖传播，如同覆盖城市的巨型"空气滤网"，让空气更清新。寂静的雪被之下，是麻雀、喜 鹊等常见鸟类，松鼠、野兔等小型哺乳动物觅食、避寒与栖息的天然庇护所，既维系了城市及周边的生 物多样性，更守护着它们减缓代谢、积蓄生机的微观生态世界。 更重要的是，要积极推动全社会公共意识的转 ...

"老科学家学术成长资料采集工程" 是根据国务院领导同志的指示精神，由中国科协牵头联合11个部委 共同实施的一项抢救性工程，旨在系统抢救和保存中国现当代科学家的珍贵历史资料。这一工程于2010 年正式启动，截至2024年底，已成功为700多位科学家建立了学术档案，将散落各处的第一手资料集中 到中国科学家博物馆永久珍藏，系统性转化为国家永久保存的公共资源，让科学家们的故事走出实验 室，成为激励全社会的精神财富。 2025年，我国环境科学界的老科学家代表刘鸿亮院士和任阵海院士的资料采集工作正式立项。在为老院 士们整理学术资料时，一页页泛黄的手稿、一张张定格历史的老照片无声地诉说着新中国生态环境科技 从无到有、从弱到强的艰辛历程。遗憾的是，任阵海院士没能等到他的传记出版。这也提醒我们，我国 第一代生态环境科技工作的开拓者和亲历者们正在老去，已有多人相继离世，他们亲身经历的历史细 节、他们脑海中的记忆、尚未系统整理的经验结晶，正不可避免地随着时间流逝。抢救这些记忆，已是 一项迫在眉睫的使命。 这些宝贵记忆记录了鲜活的生态环境科技史。生态环境科技史不同于侧重社会影响的环境史，而是环境 知识、技术方法和工程体系的内在演进发 ...
