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”

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].
