This work investigated the environmental sustainability of a town sewage treatment plant,located in Sichuan Province,China,using emergy approach.After considering the characteristics of this system,i.e.direct pollution removal but indirect and direct pollution emissions impact,a targeted emergy-based indicator system was proposed to describe its comprehensive performance,including Cost per unit pollutant eliminated (CUPE),Ratio of positive output (RPO),Environmental loading ratio (ELR),and Sustainability index (Sl).
