Decompositon of co2Emissions in Iran(Case of Power Plant)

The environmental problems especially climate changes due to significant increase in green housegases,have been a global problem in last few decads.Among the green housegases,carbondioxid(co2)is the most important.The average co2emission is increased from 607kg in 1967(1346) to 4977.7kg in 2003(1382) and 6881.7kg in 2007(1386)respectively.It shows that co2emissionrate is 11times.The social costs for deterioration of environmental due to consumption of fossil fules in 2007(1386) in Iran for SPM,CO2,SO2,NOX,is about 92195Bilion Iranian Rials which equals to 19.31of GDP.The CO2portion has been 39381Bilion Iranian Rials which is about 9414Bilion Iranian Rials was emitted by power plants.Therefor ,the factors that affecting co2emission ,should be studied considering high rate of co2production in Iran especially by power plants.In this research by means of algebraic decomposition methods the observed changes are analyzed in to five different factors:productioneffect,structural effect, energy intensity effect and ful mix effect.This research has been done for period of 2001-2006(1380-1385) for the Iranian power plants.The research shows thatout put effect was the most effect on increasing co2emissions.And co2emissions are possible to decrease without decrease out put if structural and efficiency energy and ful mix improves.
