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.
