Social (External) Costs of NOx, SO2 and CO2 Emissions from Energy Sector (Power Plants) in Iran

In this research social (external) cost of NOx, SO2 and CO2 emissions from energy sector (power plants) in Iran were estimated. For the first time, we used benefit transfer method and by adjusting international coefficients of social costs, these costs estimated for each kind of power plants (including steam, gaseous, and combined cycle). Different scenarios in this research are consisting of carbon trading, life statistical indexes, etc. At first level we survey 5 selected power plants (for case study) in Iran and then the results generalized to all power plants. Social (external) costs for 3 above mentioned gases; each type of power plants and for one kilowatt hours of electricity was estimated. The range of social (external) cost for each Kwh of electricity is 690 to 1330 Rials. The results define that average social (external) cost per kilowatt hours is about 1330 Rials.
