Abstract: The Green Index as a new indicator to determine the environmental performance has been developed in order to reduce the unfavourable environmental impacts of the wastewater treatment plants. The main aim of this study is to reveal the environmental performances of the wastewater treatment plants. An industrial and a municipal wastewater treatment plant in Turkey have been compared in terms of the Green Index. The results revealed that in August, for the municipal and the industrial wastewater treatment plants, CO₂ emission values were 0.972 and 0.42 kg/h, respectively. N₂O emissions were also 8.7 and 1.53 kg/h, respectively. CO₂ emissions in September were with the values of 0.507 and 0.657 kg/h for the municipal and the industrial wastewater treatment plants, respectively and N₂O emissions were 5.4 and 1.2 kg/h, respectively. The Green Index of industrial wastewater treatment plant was lower than the municipal one with the values of 1.13 and 1.36, respectively.
