新的研究显示,由于方法过时,许多国家低估了废水甲烷的排放量。 Many nations underreport wastewater methane emissions due to outdated methods, new research shows.

由于会计方法过时和数据不完整,许多国家的废水温室气体排放量,特别是甲烷排放量报告不足,导致实际排放量与报告排放量之间的巨大差距。 Many countries are underreporting wastewater greenhouse gas emissions, especially methane, due to outdated accounting methods and incomplete data, leading to a significant gap between actual and reported emissions. 最新研究表明,如果使用现代技术和直接测量方法,特别是对于分散、非正式和漏泄的系统,排放量可能更高几成。 Updated research shows emissions could be tens of percent higher when modern techniques and direct measurements are used, particularly for decentralized, informal, and leaky systems. 专家敦促各国采用IPCC的新指导方针,扩大监测范围,并包括所有废水源, 以改善气候规划, 通过生物气捕获等技术实现成本有效的减排. Experts urge nations to adopt newer IPCC guidelines, expand monitoring, and include all wastewater sources to improve climate planning and unlock cost-effective reductions through technologies like biogas capture.
