Abstract

Electricity generation in Korea mainly depends on thermal power and nuclear power. Especially the coal power has led to the increase in CO2 emissions. This paper intends to analyze the current status of CO2 emissions from electricity generation in Korea during the period 1990∼2016, and apply the logarithmic mean Divisia index (LMDI) technique to find the nature of the factors influencing the changes in CO2 emissions. The main results as follows: first, CO2 emission from electricity generation has increased by 165.9 MtCO2 during the period of analysis. Coal products is the main fuel type for thermal power generation, which accounts about 73% CO2 emissions from electricity generation. Secondly, the increase of real GDP is the most important contributor to increase CO2 emissions from electricity generation. The carbon intensity and the electricity intensity also affected the increase in CO2 emission, but the energy intensity effect and the dependency of thermal power effect play the dominant role in decreasing CO2 emissions.
