此次活动诞生了全国首个污水行业"尾水回用"与"碳减排"挂钩的碳普惠方法学，标志广州成为全国首个 在生活污水处理领域实现碳普惠方法学备案的城市。污水尾水的"低碳价值"从"看不见"变为"可监测、 可报告，可核查"，将为城市水务领域碳资产开发提供关键技术支撑。 与此同时，广州水投集团还通过6051吨碳普惠自愿减排量预捐赠，为2025年第十五届全运会"绿色、共 享、开放、廉洁"办赛目标注入水务力量，助力广州树立体育赛事低碳发展与城市水务绿色转型的双重 标杆。此举背后，实际上凝聚着广州水务行业的科技"硬实力"。 （原标题：全国首个污水尾水回用碳普惠方法学发布，助力全运"碳中和赛事"） 南方财经记者伍素文 广州报道 污水厂达标尾水回用有了"碳普惠规则"。 9月30日，广州水投集团联合广州市生态环境局、市水务局、市国资委、十五运会和残特奥会广州赛区 执委会（下称"市执委会"）等单位举办《广州市污水处理厂达标尾水回用碳普惠方法学》（下称《方法 学》）发布及碳捐赠仪式。 广州市国资委市管一级调研员林暖标表示，《方法学》的落地，是市属国企发挥主业优势、引领行业标 准建设的生动实践，彰显了广州国企在低碳转型中的"排头兵"作用，为国 ...

Core Viewpoint - Guangzhou has become the first city in China to establish a carbon benefit methodology linking wastewater treatment plant effluent reuse with carbon reduction, marking a significant advancement in the wastewater industry and supporting the city's low-carbon development goals [1][2][3]. Group 1: Carbon Benefit Methodology - The methodology, titled "Guangzhou's Carbon Benefit Methodology for Wastewater Treatment Plant Effluent Reuse," is the first of its kind in the country, directly linking effluent reuse with carbon reduction [2][3]. - It employs a "differential method" to calculate carbon reduction by comparing the carbon emissions from conventional water supply processes with those from effluent reuse systems, allowing for precise quantification of greenhouse gas reduction benefits [2][4]. - This methodology transforms the "invisible" low-carbon value of wastewater effluent into a "measurable, reportable, and verifiable" asset, providing essential technical support for future carbon asset development in urban water management [1][2]. Group 2: Contribution to Events and Industry Standards - Guangzhou Water Investment Group has donated 6,051 tons of carbon reduction credits to support the green goals of the 15th National Games and the Special Olympics, showcasing the integration of carbon reduction efforts into major city events [1][6]. - The methodology fills a gap in the standards for carbon reduction accounting in the wastewater sector, offering a clear path for wastewater treatment enterprises across the country to quantify their carbon reduction achievements [3][4]. - The establishment of this methodology is seen as a practical demonstration of state-owned enterprises leading industry standard development and contributing to low-carbon transitions [3][4]. Group 3: Technological Innovations and Achievements - Guangzhou Water Investment Group has developed a comprehensive carbon management system covering water, sludge, gas, electricity, and carbon, enhancing its capabilities in green and low-carbon technology [6][7]. - The company has established nine provincial and municipal technology innovation platforms, holds 165 patents, and has achieved several international leading standards in technology, contributing to significant advancements in wastewater treatment [7][8]. - Future plans include further integration of green low-carbon technology research with voluntary carbon reduction credit development, aiming for breakthroughs in smart wastewater treatment and real-time carbon footprint accounting [8].
