Özet:

Rapid urbanization causes environmental challenges as well as social, economic and cultural problems in today's cities. Especially metropolitan cities are human settlements most affected by environmental and ecological threats. Cities, turning threats such as environmental pollution and ecological deterioration into an opportunity, are ahead of their other competitors on a global scale. In the process of creating a sustainable city, measuring environmental performance has great importance. In this study, it is aimed to evaluate the environmental performance of our metropolitan cities and to raise awareness in this area. Multi-criteria decision-making methods were used in the evaluation. The literature, expert opinions and accessibility of data were effective in determining the criteria used. Eleven criteria used in the evaluation are; number of wastewater treatment plants, amount of wastewater treated in wastewater treatment plants per person (thousand M3 / year), daily wastewater discharged in municipalities (Liters/Person-Day), daily amount of water taken per person (Liters/ Person-Day), average amount of municipal waste per person (kg / person-day), capacity of drinking and potable water treatment plant (thousand M3 per year), number of drinking water treatment plants, amount of drinking and potable water treated in treatment plants per person (thousand M3/ year), amount of groundwater taken for drinking and potable water network per capita (thousand M3/ year), amount of surface water taken for drinking and utility water network per capita (thousand M3/ year) ) and particulate matter. The weights of the criteria were calculated by the Entropy Method, and the environmental rankings of the metropolitan cities were obtained by COPRAS and ARAS Methods. In both methods, close sequences were obtained. Istanbul, Ankara, Izmir, Eskisehir, and Bursa were among the best performing cities; Aydın, Konya, Tekirdağ, Muğla, and Kahramanmaraş were the least performing cities.
