이산화탄소 배출량을 고려한 국내 컨테이너터미널 환경 효율성 분석 = A Study on the Environmental Efficiency of the Container Terminals in South KoreaConsidering Carbon Dioxide Emissions

국문 초록 (Abstract)

전 세계적으로 기후변화에 대응하기 위하여 탈탄소화의 중요성이 강조되고 있으며, ‘2050 탄소중립’이 글로벌 의제로 부상하였다. 국내 항만공사는 정부의 탄소중립 추진과제에 맞추어 세계적인 탄소중립 규제 흐름에 동참하고 있다. 항만에서 탈탄소화가 중요하게 인식되기 시작하면서, 2010년대 이후로 유해산출물을 고려한 컨테이너터미널 효율성 분석이 다양하게 진행되고 있다. 하지만, 이산화탄소 배출량을 고려하여 국내 컨테이너터미널의 효율성을 비교분석한 연구는 부족한 실정이다. 또한, 대부분의 선행연구는 IPCC 가이드라인에서 제시하고 있는 Tier 1 기준에 따라 이산화탄소 배출량을 측정하였으며, Tier 3 기준에 따라 효율성을 분석한 연구는 미비한 상황이다. 이에 본 연구에서는 17개 국내 컨테이너터미널 운영사를 대상으로 Tier 3 방식 기준 이산화탄소 배출량 지표를 활용하여 효율성을 분석하였다. 그리고 DEA-SBM 모형과 Undesirable Outputs 모형 분석결과를 비교분석하여 유해산출물 고려 전후의 효율성 변화를 파악하였다.

Recently, there has been a global emphasis on decarbonization in order to address climate change and achieve carbon neutrality by 2050. In line with government regulations, domestic port authorities have also started participating in this global agenda. Since 2010, when decarbonization became an important task in ports, there have been studies analyzing the environmental efficiency of container terminals, taking into account undesirable outputs. However, most of these previous studies only measured carbon dioxide emissions based on Tier 1, whereas this study is the first to analyze the environmental efficiency of South Korea's container terminals based on Tier 3, as presented in the IPCC guidelines. The study considered 17 container terminal operators in South Korea as decision-making units and used the DEA-SBM Model. Subsequently, an Undesirable Outputs Model was conducted to calculate the environmental efficiency.
