  • Climate change is the biggest environmental issue of our times. A variety of activities to reduce greenhouse gas emissions have been in progress to observe the Kyoto Protocol. Especially, the Energy Target Scheme is created to reduce greenhouse emission with the supervision of Korean government. This includes Green-house Gas Information Systems to promote activities in the private sector to reduce green-house gas emissions, to cut a cost of energy use, and to reduce GHG emissions. Also, the system has calculated the amount of greenhouse gases. Without any additional investment, 2.75% savings are increased over the previous year. In service sector, a cooperation of customers and employees is necessary. A reduction of GHG emissions requires a proper service organization, considering an amount of investment and payback period. Without any additional investment or replacement, employees can save energy easily turning off ventilation systems an hour before employees' departure, installing timers to turn off water purifiers and vending machines after some period of no use. The Green-house Gas Information System is similar to that of Environmental Management System. However, the Excel is the best program to calculate an amount of green-house gas emissions, and to assess for a reduced amount of GHG emissions. A goal of this research is to propose a practical method in the private sector to calculate an amount of green-house gases. The Green-house gas Information System based on Excel spreadsheet gives standards for good evaluation. The greenhouse gas information system establishes and executes the policies and objectives related to greenhouse gas emissions Similar to ISO 14001 environment management system structures, the advantages of using simplified Excel Sheet for calculating GHG emissions and reducing GHG emissions are easy to access.

  • 교통부문의 지속가능성(sustainability)을 유지하기 위하여 대중교통중심의 도시개발(transit oriented development, TOD), 자전거나 보행 등 녹색 교통수단의 이용활성화, 그리고 차량운행시 배출되는 온실가스(green house gas) 를 감축하는 정책 등 다양한 방안들이 제시되고 있다. 이중 온실가스 배출량에 대한 다양한 연구들이 제시되고 있으나, 교통측면의 행태적인 분석에는 한계를 가지고 있다. 본 연구는 교통측면에서 좀 더 행태적인 측면을 고려한 온실가스 배출량 추정식을 제시하는 것이 연구의 목적이다. 즉, 특정 존에서 발생하는 차량으로 인한 온실가스 배출량을 기종점간 통행수요(travel demand for each OD pair)와 통행거리(travel distance)를 반영하여 결정한다. 여기서 기종점간 통행수요는 통행비용의 함수로 중력모형(gravity model)을 이용하여 구해지며, 통행거리는 평균 통행거리가 아닌 기종점간 실제 통행거리를 고려한다는 점이 기존 연구와 차이가 된다. 또한, 본 연구에서 제시하는 온실가스 추정식의 적용성과 활용성을 검토하기 위하여 통행비용에 대한 온실가스 배출량의 민감도(sensitivity)와 탄력성(elasticity)을 유도하며, 정책적 측면에서 온실가스를 감축하기 위한 온실가스 통행료(green house gas pricing)의 부과 효과에 대해서도 검토해 본다.

  • Considerations for green house gas (GHG) monitoring over next generation network (NGN) are regarded as a green convergence service for the successful reduction of GHG emission leading to resolve global warming issue in that NGN is expected to provide secure connections to fixed-and-mobile converged (FMC) features. Model-based scenario approach is an appropriate way to standardize and actualize the desired service. This paper first describes the service scenario of GHG monitoring service over NGN.

  • The purpose of the study is to estimate the Green-House-Gas (GHG) emissions from domestic eel farm in the water recirculation system or still-water system by the assessment of energy consumptions and GHG emissions for establishing to reduce standards of GHG from a sustainable perspective. GHG emission components as seeds, feed, fuel, electricity, fixed capital, fish respiration, and others were analysed at the different culture type between water recirculation system and still-water system by 3 stage farm size of small, medium, large scale. The result showed that the mean GHG emission of the eel farm was $18.7kg{\cdot}CO_2$ in the stage of production per fish 1kg at different culture type and farm size. Therefore it could be useful for policy, planning, and regulation of aquaculture development with establishing GHG reduction standards.

  • 온실가스(green house gas: GHG) 감시는 지구의 기후변화를 방지하기 위해 필수적인 수단이 되고 있다. 기존 연구에서 글로벌 인프라인 NGN(next generation network)을 통해 온실가스감시를 수행하기 위한 서비스 시나리오가 제시되었으나 추상적인 단계에 머무르고 있어서 실제로 NGN에 적용하는 데에는 어려움이 있다. 본 논문에서는 NGN 내에 탑재될 기능들을 중심으로 온실가스감시서비스 시나리오를 제시하여 실제 NGN에서 적용이 가능하게 하기 위한 기반을 제공한다.

  • During the past decades, energy and Green House Gas(GHG) emissions has risen as a global issue. This paper is about the energy intensity and the GHG intensity in a university campus using the weighting factor of total occupied time to the members of the university. Through this analysis, we could separately estimate GHG intensity per full-time and part-time members under the situation that the measuring data is not perfect. This analyzing procedure could be applied to other non-manufacturing institutions such as school, hospital, governmental institute, office building etc.

  • The new climate regime for practical reduction in green house gas(GHG) emissions was launched in Paris at Dec. 2015. The Korea government would make various policies and plans in order to achieve the BAU 37 % emission reduction goals by 2030. In this study, the current situation and the possible corresponding methodology to the GHG emission reduction of Korea paper industry were investigated. Although the GHG emission reduction in KOREA paper industry has been successfully conducted compared with other industries until now, the more efforts for controlling GHG emission would be required to meet the new climate regime. The efficiency of various GHG reduction projects conducted by Korea paper companies was evaluated to find efficient way for GHG reduction. The certified methodologies of the external project based offset systems in Korea GHG emission trading scheme were also reviewed for providing the possible way to develope tailored methodology to the Korea paper industry.

  • 본 연구에서는 국내 음식물쓰레기 (food waste, FW) 분야에 대한 재활용 현황을 분석하고 green house gases (GHG) 배출 관리방안에 대해 고찰하였다. 연구 결과, FW의 자원 활용성을 향상시키고 GHG 배출을 부가적으로 저감시키기 위해서는 적절한 선순환체계가 필요하다는 결론을 얻었다. 효과적인 퇴비화를 위해서 우선 GW의 활용이 고려되었다. 특히 3세대 바이오매스로써의 GW (phytoplankton, periphyton, macrophyte etc.)는 퇴비화 공정에서 FW의 단점을 보완하고 질적 능력을 향상시킬 수 있는 좋은 기능성 첨가제로 판단된다. 또 하나의 접근법은 최종산물 (예: 토양개량제)을 오염물질 완충이 가능한 bio-filter로 가공하여 그린인프라에 적용하는 방안이다. 이러한 생태공학적 접근과 시도는 안정화된 재활용 산물의 기존 활용 이외에도 FW 자원화에 대한 새로운 적용처를 제시할 수 있으므로 향후 효과적인 탄소 넷제로 (Net-Zero) 시스템 구축에 기여할 수 있을 것으로 판단된다.

  • Global aviation is projected to grow in demand by an annual average of 4.1% between 2014 and 2034. It can be said that environmental impact from aviation will therefore be expected to increase on a similar scale. As regards civil aviation emissions, the sector contributes between 2~3% to International aviation GHG emissions. In the European Union(EU), aviation emissions account for about 3% of the EU's total green house gas emissions, of which a majority are said to come from international flights. In terms of traffic volume in 2013, Korea's international aviation industry 11th with regard to passengers and 3rd with regard to cargo, attaining the overall rank of 5th in the world. GHG emissions has been increasing steadily over the last 4 years, averaging 3.9 percent a year, due to the growth of low cost carriers and the increased demand for air transportations. As for aviation in Korea, there are a number of means intended to attain the Government's emission control objective in an efficient manner, such as AVA (Agreement of Voluntary Activity), TMS (Target Management System) and ETS (Emission Trading Scheme). In addition, the Government intends to better adapt to ICAO's Global MBM(Market-based Measures) that will come into performance on Year 2020. In the study, we focused on GHG mitigation measures that is fulfilling the AVA, TMS, ETS in the Government and suggest the effective measures to reduction the aviation GHG emissions.
