초록

인간의 인위적 활동에 의한 이산화탄소의 배출 증가는 지구 온난화의 원인 중 하나로 알려져 있으며, 기상이변 등과 같이 지구 환경에 막대한 영향을 미치고 있다. 이로 인해 최근 들어 이산화탄소 배출량을 규제하기 위한 움직임이 활발해지고 있다. 또한 배출된 이산화탄소의 환경영향을 평가하기 위해, 일본 조선학회 산하의 IMPACT 위원회에서는 자연의 개발로 인한 환경영향과 경제성을 동시에 고려하여 평가할 수 있는 포괄적 지표인 Triple I (III)를 제안하고 있다. 본 연구에서는 III를 적용하여 컨테이너 선박의 운항 시 배출되는 이산화탄소로 인한 환경영향 및 경제성에 대해 생애주기 평가를 통해 정량적으로 비교하였다. 또한 선박의 규모 변화 및 운항 항로의 변경에 따른 포괄적 환경영향평가를 실시하였다. 결과적으로 선박의 운항에 의한 포괄적 환경영향평가는 선박의 규모보다는 이산화탄소 배출량과 밀접한 선박의 운항 항로에 보다 더 민감한 것으로 판단되었다.

The increase of carbon dioxide ($CO_2$) emission is known as one of the major causes of global warming, and it has a strong influence on the global environment. Therefore many researchers and politicians have tried to regulate the $CO_2$ emission. In regards to the matter, the IMPACT (Inclusive Marine Pressure Assesment and Classification Technology) committee under the Japan Society of Naval Architects and Ocean Engineers (JASNAOE) has developed an inclusive environmental impact assessment index, so-called "Triple I(III)", in order to assess the environmental impact including economic factors due to the artificial development of marine. In this study, III was applied to compare between the environmental impact of $CO_2$ emitted by container vessels during their life-cycle period and economic benefit due to their operating. Furthermore, III was also applied to assess the comprehensive environmental impact for the cases with various capacities of container vessels and different sailing route. From the results, the case for shortening of the sailing route is more effective to get the advantageous assessment results of III than the case for varying the size of vessels.
