The growing amount of using the fossil fuel is bringing about environmentally, economically serious problems like as global warming. To solve the problems, the international society has begun to decrease greenhouse gases through the international agreement like as the climate change convention. In South of Korea, it was presented practical goal of Green Development try to decrease greenhouse, which is the future 60 years vision. And, it contains the strategies of Green Development and 5th Plan of Green Development. Nowadays, the government accepted the active alternative scenario 3, which is the goal of 4% decrease in greenhouse gases until 2020's, presented by Presidential Committee on Green Growth. This study established the strategies of Transport Demand Management to decrease the greenhouse gases in transportation part, and then we measured the effect of them. As a result, if it takes effect the aggressive strategies annually, it will cut greenhouse gas pollution by 3.1%, which is 7,590,000t$CO_2eq$, in transportation part. So, we can expect that it would be the effective policy tool to achieve the goal of government, which is the Green Development, if it controls the strategies of TDM effectively by the political needs.

This paper constructed the single country sequential dynamic CGE model to analyze the economic impacts of subsidizing water industry under the GHG emission abatement policy in Korea. We introduced the carbon tax to reduce the GHG emission and made two scenarios. One is to transfer the total tax revenue to household. The other is to mix the tax transfer and water industry support. Our Simulation results show that the macroeconomic effects might be positive by subsidizing water industry compared with the pure tax transfer. However, the support of water industry doesn't contribute to head for the non-energy intensive economy because it's economic activity highly depend on fossil energy and energy intensive products as intermediate demand. This means that it is important to make efforts on the cost effective measures such as energy technology progress, alternative energy development, and energy efficiency improvement in water industry against climate change policy.

The purpose of this study is to analyze the green-house gas emission reduction of the pump scheduling system applied to the water-supply facilities in all objectivity with AMS-II.C/Version 13 in CDM methodology. To calculate the baseline and project emission in Paldang Pumping Station (III) the data about water flow, water level, electricity consumption, etc. before and after the implementation of project was used. This study considers internal facility (mostly for lighting) electricity consumption and grid loss in order to get more accurate emission reductions. The methodology used in this study will be able to apply to different energy improvement techniques to calculate emission reductions in water supply facilities.

Construction waste is generated at a rate of approximately 221,102 tons/day in Korea. In particular, mixed construction waste generates approximately 24,582 tons/day. The other components were recycled by 98.9%. The amount of greenhouse gas emissions from the waste was 17.1 million tons of CO2 equaling 2.3% of the total greenhouse gas emissions. To reduce greenhouse gas emissions, reducing the environmental impact is becoming increasingly important. However, appropriate treatment must first be established, as mixed construction waste is also increasing. Thus, an effective plan is urgently needed because it is frequently segregated and sorted by the landfill and incinerated. In addition, there is an urgent need to prepare various effective recycling methods rather than a simple treatment. Therefore, this study analyzed the environmental impact of the treatment of mixed construction waste by calculating greenhouse gas emissions. As a result, the highest greenhouse gas generation occurred during the incineration stage. Moreover, the optimal method to reduce greenhouse gas emissions is recycling and energy recovery from waste. In addition, the amount of greenhouse gas generated during energy recovery from the waste stage was the second highest. However, greenhouse gas emissions can be reduced by using waste as energy to reduce fossil fuel consumption. In addition, for the transportation stage, the optimal reduction plan is to minimize the amount of greenhouse gas emissions by setting the optimal distance and applying biofuel and electric vehicle operations.

활동기준원가의 개념을 적용하여 Co2 절감대책을 수립한다. 물질흐름원가계산(MFCA; Material Flow Costing Accounting)을 통해 물질의 흐름을 파악하고 Co2 등의 절감을 원가로 측정하고 관리하고자 한다. MFCA(물질흐름원가계산)를 이용하여 에너지 사용량에 대한 단위시간당 가공비 계산하면 원가관리를 정확하게 할 수 있다. 그리고 구체적인 공급체인별 에너지 사용량 및 온실가스 배출량에 대한 개선 목표를 설정할 수 있다. 시뮬레이션 기법을 이용하면 프로세스별 원가계산이 가능하고, 다양한 시나리오를 편리하고 신속하게 분석할 수 있다.

The expense Our country's land logistics system is becoming backlog day by day. The greenhouse gas which it discharges specially from the vehicle causes a ecocide and traffic expense to make. The traffic energy curtailment which the government enforces during that time and environment-friendly green goods policy lost the effect. Therefore, This research propose the car-ferri network which is the most effective logistics system substitutes the land logistics system. This research will contribute improving the north and south logistics network of Pusan and Seoul region and will be able to reduce a various goods expense.

In this study, the S University's energy usage, greenhouse gas emissions situation and potential reduction amount were analyzed using a long-term energy analysis model, LEAP. In accordance with the VISION 2020 and university's own improvement plans, S University plans to complete a second campus through expansion constructions by 2020 and by allocating the needed land. Accordingly, increases in energy usage and greenhouse gas emissions seem inevitable. Hence, in this study, the calculations of potential reduction amount by 2020 were attempted through the use of LEAP model by categorizing the energy used based on usage types and by proposing usage typebased reduction methods. There were a total of 4 scenarios: a standard scenario that predicted the energy usage without any additional energy reduction activity; energy reduction scenario using LED light replacement; energy reduction scenario using high efficiency building equipment; and a scenario that combines these two energy reduction scenarios. As scenario-based results, it was ascertained that, through the scenario that had two other energy reduction scenarios combined, the 2020 greenhouse gas emissions amount would be 14,916 tons of $CO_2eq$, an increase of 43.7% compared to the 2010 greenhouse gas emissions amount. Put differently, it was possible to derive a result of about 23.7% reduction of the greenhouse gas emissions amount for S University's greenhouse gas emissions amount through energy reduction activities. In terms of energy reduction methods, changing into ultra-high efficiency building equipment would deliver the most amount of reduction.
