Evaluating the Quality of Tehran's Urban Environment Based on Sustainability Indicators

The objective of this study is to measure the city of Tehran's environmental quality in 2006 (the last census year). Primarily, with a comparative analysis of a variety of urban sustainability indicator models, a collection of 54 indicators have been chosen and categorized as indicators of increase or decrease in urban environmental quality in the form of a simple mathematical model. Based on the aforementioned model, Tehran's environmental quality in 2006, having obtained a score of 59.5%, has been evaluated as "middle ranking". After continuing the evaluation more meticulously, it became known that the individual healthcare indicator with a 91% score and the safety and security indicator with a 19% score had the highest and lowest quality respectively in the city. Repeating this evaluation in the future will show the condition of the city's movement toward establishing a sustainable city. Furthermore, it will clearly demonstrate the reasons affecting the high or low speed of this movement.
