최근 들어, 신재생에너지 사용에 따른 온실가스 발생량이 지속해서 증가하고 있다. 이에, 본 연구는 2010~2021년 기간에 한국의 신재생에너지 발전 분야의 온실가스 배출량에 대해 LMDI (Log Mean Divisia Index) 방법을 활용하여 온실가스 배출량 증감 요인을 분해분석하고 그 영향을 살펴보고자 하였다. 특히, 본 연구에서는 분해분석을 위한 주요 요인으로 신재생에너지 비율, 신재생에너지 종류, 온실가스 배출계수, 전력집약도, 인구 등 5가지를 고려하였다. 요인분석 결과, 신재생에너지 비율, 신재생에너지 종류, 온실가스 배출계수가 온실가스 배출 증감에 중요하게 작용했지만 전력집약도와 인구의 영향은 미비한 것으로 나타났다. 나아가, 온실가스 배출량 증감에 있어 신재생에너지 관련 배출권거래제 및 온실가스 ·에너지 목표관리제의 정책 시행이 중요한 결정 요인으로 작용했음을 확인하였다. 본 연구의 결과는 한국의 탄소중립 목표 달성을 위한 온실가스 발생 저감 해결책 및 방안 모색과 중장기적 에너지 발전 방향 수립에 중요한 기초자료로 활용될 수 있을 것으로 기대된다.
The amount of greenhouse gases (GHG) generated by the use of renewable energy continues to increase. Therefore, this study performs a decomposition analysis of the factors contributing to the increase or decrease in GHG emissions using the Log Mean Divisia Index (LMDI) method and data on GHG emissions from Korea's renewable energy power generation sector between 2010 and 2021. To this end, five main factors for decomposition analysis were considered: renewable energy ratio, renewable energy type, emission coefficient, power intensity, and population. The factor analysis showed that the renewable energy ratio, renewable energy type, and emission coefficient had notable impacts on the increase or decrease of GHG emissions, while power intensity and the population did not have a significant impact. Furthermore, the policy implementation of the renewable energy-related emission trading system, the GHG, and the energy target management system were important determinants of the increases and decreases in GHG emissions. The results of this study can be used as basic data for finding further solutions and measures to reduce GHG emission and for establishing mid-to long-term energy generation directions for Korea to achieve its goal of carbon neutrality.
