LOGARITHMIC MEAN DIVISIA INDEX (LMDI)Q3

Abstract

 Power sector in Iran, count for a share of 28.2 percent of the total CO2 emissions, so it is the biggest emitter of greenhouse gases. This study uses Logarithmic Mean Divisia Index (LMDI) technique to examine the role of five factors (economic growth, fuel intensity, electricity intensity, structure and quality of fuel) influencing CO2 emissions of the Power Plant sector in period 1997-2008. Thermal efficiency and the fuel mix effects have been analyzed to determine the factors affecting changes in CO2 emissions index. Results show that the economic growth has the highest effect on increases of CO2 emissions in Power sector, during the whole period of study. Then, fuel quality effect, fuel intensity effect and structure of production effect respectively, have influenced the growth of CO2 emissions. Changes in fuel mix have had the greatest effect on the increase of CO2 EMISSION INDEX, especially for period 1387-83. EMISSION INDEX display that combined cycle power plant has least EMISSION INDEX among all types of THERMAL POWER PLANTs and hence it is most suitable THERMAL POWER PLANT for environment amongst THERMAL POWER PLANTs.
