In the midst of worldwide response to climate change, the advanced ports including LA/LB(Los Angeles/Long Beach) has started to reduce carbon emission from port area which has not been targets of interests in the worldwide cooperation. Recently, the Port of Busan has started to reduce carbon emission from the port area under the Green Port Strategy in Korea. However, the low-carbon port management increases the cost of port management and negatively impacts the port competitiveness in the short term. Therefore, the Busan Port Authority is carrying out the low-carbon projects directly and has not transfer the cost to the port users, such as shipowers, cargo owners and terminal operators. However, the Port Authority of LA/LB has transferred the cost at low-carbon port management to customers of port. In this study, comparative analysis on cost of low-carbon port management at Busan and LA/LB is carried out for sustainable port management.

부도등대는 무인도서로 조류신호소 및 등대 운영에 필요한 전력을 발전기로 생산하고 있어 많은 유류소모 발생으로 저탄소 녹색성장의 정책방향에 따라 태양광에너지 이용을 확대하고, 발전기 가동시간을 최소화하여 유류비 절감하고자 함, 최근 3년간 발전기 유류를 월평균 $4,600{\ell}$ 사용했으나 전원시스템 개량이후 월평균 $1,300{\ell}$ 이하로 줄여 년간 유류비 예산 약 69,000천원 절감되었다.

최근 국제해사기구(IMO)의 해양환경보호위원회에서(MEPC)는 선박에서 대기로 방출되는 CO2의 양을 최소로 하기 위해서 신조선 설계 건조시 에너지효율지수(EEDI : Energy Efficiency Design Index for new ships), 에너지 효율지표(EEOI : Energy Efficiency Operational Indicator), 그리고 에너지 효율관리 계획(SEEMP : Ship Energy Efficiency Management Plan) 지수들을 이용하여 전 세계 이산화탄소 배출 규제 방침을 운영하고 있다. 이러한 환경규제 강화와 발맞추어 세계 각국은 지속적인 Green-ship의 개발과 저탄소 고효율 선박의 운항을 위해 연구와 노력한다. 본 연구에서는 선박이 움직이는데 있어 동력이 시작되는 부분과 그 힘이 전달되어 운항자의 의식이 반영되어 선체의 이동으로 이어지기까지 흐름에 대해 도식 및 수식으로 정리하였다. 그리하여 해상의 상태와 이에 따른 운항결정이 어떤 결과를 초래할 수 있는지 살펴보고 이 부분에서 운항효율을 증대시킬 수 있는 부분에 대해 모색해 보았다. 또한 엔진의 상태에 따른 연료 절감율에 대해 살펴보고 보다 경제적 운항을 위한 적정 RPM과 속도 등에 대해서 고찰해 보았다. 이 같은 정리를 통해 앞으로의 Echo-ship, Green-ship의 연구방향에 대한 초석으로 삼고자 한다.

This paper focuses upon the relationship between port and port city. The purpose of this study is to theoretically review the relationship between port and its city, and to identify crucial policy directions for mutual development of port and the backward city in the case of Gwangyang Port (GP), Korea. The contents of this paper consist of five main sections: introduction; a concept of port-port city relationship; an analysis of the relationship between GP and its city; policy directions for GP city; conclusion. This study was mainly conducted by a literature review of the papers/reports and the analysis of secondary data. Significant policy strategies are associated with development of value-added logistics, expansion of additional port business, vitalization of port hinterlands, and establishment of port logistics clusters in terms of port economic function. Green port operation, improvements of coastal environment, establishment of port waterfronts, and conceptual port redevelopment master plan are included in the major port city development strategies in terms of sustainable development. Another major port city development strategies contain major port city master plan, institutional arrangements for port city development, specialized port city development policy, and formation of free trade port city in relation to integrated port-port city planning and management.

Recently, international society strongly concerns global green house effect. As a result each nation introduces green policy for their economy and sustainable development. The emissions of carbon dioxide come from various sources, such as ports and port activities. Especially, port is a logistics hub for shipping, road and railways. Therefore, successful reduction of emissions in the port may encourage other transportations to reduce emissions. Korea as developing country is excused from Annex I countries which committed themselves to reduce four greenhouse gases. However, Korea is going to be placed in Annex I countries in 2013. Korean economy is heavily dependent on international trade and especially, 99.8% of its international trade cargoes is transported through the ports. Therefore, Eco-port plays a very important role in future Korean sustainable development. By introducing the most advanced port pollution regulations, Japan has taken a immediate step for Eco-port policy. International trade is very significant in Korea as well as in Japan, both nations have similar industrial structure. Therefore, Korea should pay attention to Japanese Eco-port policy and activities. This paper examines Japanese Eco-port policy and its' implications in order for Korea to find the most efficient way to reduce the emissions as Korea should reduce greenhouse gas emissions in post kyoto system.

All over the world more and more attention is being paid to green management which enables environment-friendly sustainable development. To keep up with these global trends and in response to the government's "low carbon green growth" policy, many efforts are being made in the port and logistics in order to drastically reduce carbon emissions and save operating expenses. To this end, the engine power source of the cranes in the container terminal is being replaced with electricity from fossil fuel. Among those cranes, especially e-RTGC has been proved to be practical and excellent in its performance through many previous studies. However, no empirical study has yet been made on its introduction effects when e-RTGC has been introduced to the container terminal. In the meantime, however, many domestic container terminals have introduced e-RTGC, and so some data have been accumulated for further research. Under these circumstances, this study has tried to make an empirical study through the case study of D container terminal, checking the restriction factors to be considered at the time of eURTGC introduction, and analyzing its introduction effects and problems. We have high expectations that this study will provide key consideration factors and empirical analysis data to the decision makers who plan to introduce an e-RTGC system, and also will be used as a reference to the development direction of e-RTGC.

On the crisis of international economy, the government is making an effort to seek economic growing motivation with the method of overcoming economic crisis and 'low carbon green growth'. Furthermore, to promote maritime vessel traffic service related inefficient energy wastage was revealed and eco-friendly alternative energy was accepted because of high price of oil in the beginning of 2008. In this situation, I'm going to discuss the possibility of eco-friendly energy system in maritime vessel traffic service with the way of cutting the budget and expansion of solar power generation system which was promoted to meet governmental 'energy saving plan for high price of oil'.
