  • 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.

  • The government continuously improves the RPS system to expand the supply of renewable energy, but there has been criticism that more environmental aspects should be considered to reduce GHG emission. REC weights are differentiated according to renewable energy sources. Greenhouse gas emission is one of the decisive factors, and its value is set by experts' opinion. This study assigns LCA to get accurate value of GHG emission. The LCA calculates emitted greenhouse gases from entire process of fuel production, transportation, power plant construction, operation, and decommission. This study suggests a method to change the greenhouse gas reduction effect from the existing qualitative method to the quantitative method and evaluates them. As a result, the evaluation score is changed, but the tier interval is so large that it does not affect the REC weight. Therefore, this study suggests the way that directly reflect the greenhouse gas reduction effect in the REC weight.

  • When greenhouse gas mitigation policies are implemented, energy intensive manufacturing industries are influenced much due to an increase in cost. However, industries that have price setting power are damaged less by the policies. Therefore, this paper analyzes vulnerability of energy intensive manufacturing industries to the policies by measuring price setting power of the industries. We analyzed price setting power model through ECM, employing the import prices and wages as independent variables. The industries that their prices react to import prices are price takers, which their prices are determined by rival's ones. On the other hand, the industry that their prices react to wages that mean domestic cost are price setters, and they will be less vulnerable to the policies. In addition, fluctuation of energy prices would be reflected in import prices because it influences other countries than my one. Thus, we employed energy prices as control variable to measure the net effects of import prices. As empirical results, petroleum products, chemical products, non-metallic mineral products, textiles, and motor vehicles sector have price setting power, so the industries have competitiveness on greenhouse gas mitigation policies.

  • 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 goal of this study is to analyse the effects of financial support by governmental on KERRP (Korea Emission Reduction Registration Project) in the case of descending clock auction. Result shows that about 60% of total reduction (612,000ton) can be achieved at the price of 8,000 Won/ton with the budget amount of 5 billion Won, if the benefit from energy saving by the project is not included. Also 100% of total reduction (1,015,713ton) can be achieved at the price of 4,900Won/ton, if the benefit from energy saving by the project is included. Because most projects get some benefits from the energy saving occurred by project performance, the financial support by government may not be needed. However, this type of support would be meaningful from the aspect of encouraging GHG (Green House Gas) reduction to be prepared for the potential obligation of national GHG reduction from 2013.

  • 소수력은 온실가스 배출량이 적은 친환경 청정에너지원이면서 지역의 분산전원에 기여할 수 있는 유용한 자원으로 평가되고 있다. 이러한 여건은 소수력발전 사업이 전력의 smart grid 구축 효과로 인해 가장 큰 효율성을 달성할 수 있을 것으로 기대된다. 국내 소수력발전은 1500Mw의 부존량을 가진 것으로 평가되고 있으나 계절적 편중으로 인한 가동률 부족, 경제성 부족 등으로 활발한 보급이 이루어지지 않고 있다. 특히 신재생에너지 확대 전략에도 불구하고 지원금 등 경제적 인센티브 부족으로 인해 민간부문의 참여는 상당히 저조하다. 그럼에도 불구하고 수력에너지는 환경친화적이고 잠재성이 큰 신재생에너지로 온실가스 저감과 에너지 확보에 기여할 수 있다. 특히 수력에너지는 민간투자의 어려움이 존재하므로 정부의 장기적인 기술개발투자 및 효율성 확대 정책이 중요하다. 본 연구에서는 소수력 확대의 경제 환경적 효과를 평가해보기 위해 연산일반균형모형 (CGE :Computable General Equilibrium Model)을 구축한다. 본 연구는 다음과 같이 수행되었다. 첫째, 수력발전부문과 수도사업을 구분하고 사회회계행렬을 작성하였으며, 전력부문에서 수력발전을 포함한 다단계 생산구조를 가정하였다. 둘째, 일반균형모형 방정식 체계를 작성하고 모형의 파라미터 추정 등 보정(Calibration) 작업을 수행하였다. 셋째, 국가 중기 온실가스저감 시나리오를 적용한 전망을 수행하고 소수력 확대(투자지원) 시나리오를 구축한다. 본 연구는 저감수단으로 탄소세를 부과하였다. 끝으로, 소수력 발전 보급 확대의 경제적, 환경적 파급효과를 계산하였다. 분석결과, 소수력 발전 잠재 성장을 반영한 수력에너지 비중은 약 2020년에 약 4.5% 까지 증가하는 것으로 나타났다. 이로 인한 온실가스 저감 기여분은 약 3%에 이르는 것으로 계산 되었다. 또한 수도사업과 비에너지 제조업의 산업비중은 증가하였다. 이러한 결과는 소수력 발전 확대가 화석연료 대체를 통한 지속가능한 에너지 수요에 기여하고 지역개발과 물산업 발전 등 경제적 파급효과 등을 유발할 수 있음을 시사한다. 또한 본 연구에서 고려하지 못한 소수력 기술 개발은 에너지 대체 촉진으로 인한 온실가스 저감과 녹색성장에 기여할 것이다.

  • This study is to assess the reduction of greenhouse gas emission and economic contribution by operating nuclear power plants in Korea. According to the results of applying greenhouse gas emission coefficients to the current nuclear power generation and the estimated nuclear power generation of national energy master plan, it is confirmed quantitatively that nuclear power contributes to reducing greenhouse gas emission, controlling inflation, and substituting import of fossil energies. For the reliable and cost-effective supply of energy and the active respondency to climate change, a continuous expansion of nuclear power is implied to be necessary.
