Bijan Safavi Assistant Professor of Economics, Faculty of Economics and Accounting, South Tehran Branch, Islamic Azad University, Tehran, Iran Journal Article 2018 10 28 In recent years, sustainable urban development has been considered more than ever by researchers. Therefore, in the present study, it is attempted to provide a dynamic model of sustainable development for Tehran City. To this end, a computer simulation is applied based on the system dynamics approach using VENSIM software. According to the research purpose and available data, the model is developed using the two socio-economic and environmental pollution sub-sectors. From the results of the simulation in the basic model, the following conclusions can be drawn: (1) The simulation values could well predict the actual values of the variables indicating the sustainable development of Tehran; (2) It can be said that if the same trend continues in Tehran until 2025, the population of Tehran will reach nearly 11 million people; (3) Despite the GDP growth rate considered for Tehran City, the total revenue of Tehran city will increase from 624 thousand billion Rials in 2008 to 315669 thousand billion Rials in 2025; and (4) The amount of carbon dioxide emitted from various uses in Tehran City will reach nearly 100 billion tons per year by 2025, which is very high and it seems essential to adopt appropriate environmental policies.
