Abstract :
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 co2 emission is increased 607 kg in 1967(1346) to 4977.7 kg in 2003(1382) and 6881.7 kg in 2007(1386)respectively.It shows that co2 emissionrate 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 92195 Bilion Iranian Rials which equals to 19.3% of GDP.The CO2 portion has been 39381 Bilion Iranian Rials which is about 9414 Bilion Iranian Rials was emitted by power plants.Therefor ,the factors that affecting co2 emission ,should be studied considering high rate of co2 production 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 that out put effect was the most effect on increasing co2 emissions.And co2 emissions are possible to decrease without decrease out put if structural and efficiency energy and ful mix improves.
