  • 온실가스의 배출자료는 기후변화협약 참여협상 및 저감대책 수립에 없어서는 안될 중요한 기초자료이다. 그러나 국내에서는 현재 에너지와 농업 분야를 제외하고는 온실가스의 배출원 및 배출량 조사가 미미한 실정이다. 이번 연구에서는 기후변화와 관련된 온실효과에 커다란 기여를 하고 있는 메탄($CH_4$)의 매립지 표면으로부터의 국내 배출량을 조사하고자 한다. $CO_2$, $CH_4$, $N_{2}O$, $O_3$, CFC 등의 주요 온실가스들은 여러 경로를 통해서 대기로 배출되고 있으며, 온실가스의 배출기여도를 보면 도시쓰레기의 매립이 전체 배출량에 약 3%정도 기여하는 것으로 보고되었다.

  • Today, more than thiry countries around the world are designated as a mandatory GHG(GreenHouse Gas) emissions country from the UNFCCC(United Nations Framework Convention on Climate Change). Korea is also possible to designate a mandatory GHG emissions country after Second mandatory emissions which will be started in 2013. Accordingly, Korea government has made efforts to reduce GHG and has enforced energy-related policies to deduce building energy. But there is no process such as providing of existing building improvement recommendations or expert verification for building remodeling in Korea energy-related policies compared with policies in other countries. For this reason, improvements of Korea which divided governments and city provinces are suggested. However suggested improvements are directions, so additional research is needed for detail methods.

  • Reducing emissions across all sectors requires a well-designed policies tailored to fit specific national circumstances. And every climate policymaker would like to have an accurate method of assessing the quantitative impacts of future policies to address GHG-related problems. Estimates of future changes in a nation's GHG emissions, the expected environmental impacts of future energy sector developments, and the potential costs and benefits of different climate technology and mitigation policy options are desirable inputs to policy making. Various mitigation analysis and modeling approaches helped to fill the needs for these kinds of information, and as such has been an important part of national mitigation policy making in many countries for most of two decades. This paper provides a overview of GHG mitigation policies and mitigation analysis, and sectoral mitigation circumstances and potentials.

  • 최근 IMO에서는 온실가스 배출을 규제화 하고자 하는 동향이 있으며 조만간 선박에서 온실가스 배출의 규제가 실현될 것으로 예상된다. 선박에서 배출되는 온실가스는 CO$_2$가 대부분을 차지하고 있으며 세계경제상황에 따른 영향이 고려되지만 지속적으로 증가추세에 있는 CO$_2$를 감소시키기 위한 아국의 대처방안이 필요한 시점이다. 또한 향후 발효될 EEDI를 소개하고 결과적으로 GHG를 저감시키기 위한 방안인 선형개선, 폐열회수시스템, 친환경연료사용기관, SEMP 등에 관한 내용을 다루어 보았다. 이 보고서에서는 GHG를 비롯한 NOx, SOx 및 PM과 같은 유해배출물질을 Top Down방식으로 평가함으로써 선박에서 기인하는 대기오염물질 관련 국내정책 및 해운산업의 장기적인 발전전략에 유용하게 사용될 것으로 기대한다.

  • According to governmental policies for green growth, the increase in the traffic volume of railroad is a representative method to reduce total greenhouse gas (GHG) emitted from transport. Comprehensive assessment for the GHG emission of railroad has been studied to compare the difference of transport modes just in the operating step excluded the construction step. The purpose of this study was to evaluate GHG emissions in railroad construction sector. The targets were some construction works for civil, track, building, and electric system in A line. The GHG emission source of constructing railroad infrastructure was mainly the energy consumption of heavy equipments. As a result, the civil construction sector showed more than 96% of total GHG emissions and its specific GHG emission was 2.191 ton $CO_2e/m$. Also, the specific GHG emissions of civil construction works were of the order: earthworks > tunnels > bridges > station. In future, it will be required to calculate the overall GHG emission of railroad through life cycle approaches including operation, maintenance and disposal step.
