Abstract

Some OECD countries are showing signs of decoupling in the transportation sector. In terms of sustainable development, the decoupling of economic activities and greenhouse gas emissions in the transportation sector is very important. This study calculated a decoupling index of greenhouse gas emissions in the transportation sector for 25 OECD countries. Also this study analyzed the impact of energy transition on decoupling regimes. According to the analysis, a considerable number of countries have reached the decoupling phase, and some countries have shown strong decoupling regime in which greenhouse gas emissions are reduced despite economic growth. From ordered panel logit analysis, energy transition had significant impact on achieving decoupling phase. Electrification of transport had a positive effect on the decoupling, while the gasification was not significant. In addition, small traffic, high urbanization rates, strong environmental policies, and high trade opening have had significant effects on achieving decoupling.

최근 OECD 일부 국가를 중심으로 교통부문 온실가스 배출량의 탈동조화 현상이 강화되고 있다. 본 연구는 1990~2017년 OECD 25개 국가 데이터를 이용하여 교통부문 온실가스 배출의 탈동조화 현황을 살펴보고, 에너지전환이 탈동조화에 미치는 영향을 분석하였다. 분석결과, 상당수의 국가들이 탈동조화 국면에 도달했으며, 일부 국가는 경제성장에도 불구하고 온실가스 배출량은 감소하는 강한 탈동조화 국면에 도달했다. 에너지 전환이 탈동조화 국면에 미치는 영향을 분석해본 결과, 전기화 현상은 탈동조화 달성에 긍정적인 영향을 미친 반면, 가스화 현상은 유의성이 없었다. 이 외에도 적은 운송량, 높은 도시화율, 강한 환경정책, 높은 무역개방도가 탈동조화 달성에 유의미한 영향을 미쳤다.
