  • The purpose of this paper is to a develop model for generation expansion planning that can support diverse environmental policies for the reduction of greenhouse gases (GHGs) of South Korea. South Korea is required to reduce its GHG emissions by 30% from the BAU level by 2020. The Wien Automatic System Planning Package currently used in South Korea has limitations in terms of the application of renewable energy policies and GHG targets; this paper proposes the use of an equipment planning model named generation and transmission expansion program, which has been developed to resolve such limitations. For verification of the model, a case study on the 6th Basic Plan of Long-Term Electricity Supply and Demand has been conducted. The results show that for the year 2020 South Korea's annual GHG emissions will be 36.6% more than the GHG Target Management System (GHG TMS) target set for the same year (30%). To achieve the GHG TMS target, the costs involved amount to about 72 trillion KRW (70 billion USD). Consequently, the South Korean government needs to review the performability of this target.

  • Since national GHG reduction target by 2020 has been presented in Korea, the role of railroad has been reinforced within transport system due to the allocation of reduction target into sector. So, it is necessary to manage activity data systematically for the calculation of GHG emission in railroad. Now, the activity data of diesel consumption for NIR(National Inventory Report) are provided from oil supply and demand statistics. On the other hands, the activity data collected directly from railroad operating companies are used for GHG & Energy Target Management Act. This study aimed to assess the GHG emissions using two kinds of activity data related to the diesel consumption of railroad in 2009 and 2010. As a result, GHG emissions based on oil supply and demand statistics was 636 thousands ton $CO_{2e}$, but the activity data collected from railroad operating companies showed 649 thousands ton $CO_{2e}$ in 2009. Also, the gap of $CO_{2e}$ emission was increased in 2010. These trends were caused because oil supply and demand statistics included total diesel sales volume during 1 year and the activity data collected from railroad operating companies were the amount of diesel consumption only at railcar operation and maintenance step. In conclusion, it is important to develop the management and verification system of activity data with high reliability to substitute oil supply and demand statistics in railroad sector.

  • 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.

  • The Energy and Green House Gas target management system was launched by the Korean Government in 2010. The Korea Emission Trading System will start in 2015. Therefore, simultaneous pursuit of energy saving and greenhouse emission reduction through energy use rationalization is an important obligation of Korean engineers, who import about 97% of domestic energy consumption. Economic analysis of the GHG emission reduction methodologies registered and approved by Korea Voluntary Emission Reduction (KVER) program was conducted. The results for waste heat recovery employed in an energy intensive pulp, paper and wood industry were reported. The emission reduction intensities were 9.7 kg $CO_2$/ton_pulp production. Net Present Value analysis showed that the GHG emission reduction was economically beneficial with an internal rate return of 60%. The results of exergy analysis indicated that the second law efficiencies of waste heat recovery system employed in KVER program were 77.3% and 53.6%. NPV decreased as the exergy decreased.

  • 우리나라에서 시행되고 있는 '온실가스 에너지 목표관리제'의 효율적인 운영을 통하여 실질적인 온실가스 배출을 감축하고 향후 예정되어 있는 '탄소배출권 거래제'의 원활한 추진을 위해서는 온실가스배출량의 정확한 산정이 요구된다. 폐기물부문에서 주요 온실가스배출원인 폐기물 매립시설에 대해서도 목표관리제 운영지침에서 온실가스배출량 산정방법이 제시되어 있으나 계산방법과 매개변수 등에 오차요인이 있어 적정 산정방법에 대해 검토 제안하고자 하였다. 그 결과, 메탄회수율 0.75를 기준으로 산정방법을 구분하고 그 단일값과 메탄회수량으로부터 메탄발생량을 계산하는 방법은 삭제하여 온실가스배출량 산정과정의 중복적용과 과대평가 발생요인을 해소할 필요가 있음을 알 수 있었다. 메탄발생량은 일차분해모델로 추정하고 메탄회수량은 매립시설에서 측정한 값을 사용하도록 하되 과거 메탄회수량 데이터를 확보하기 곤란한 경우에는 메탄회수량을 산정할 수 있도록 일일복토나 중간복토가 포설된 사용중 매립시설에서는 가스배제공과 간이소각 0.60, 강제포집 시스템 0.65로, 최종복토가 이루어진 사용종료 매립시설은 자연적인 포집이나 강제포집이 수행되면 0.90으로 국내 매립시설에 적합한 조건별 메탄회수율 기준값을 제시하였다. 주요 매개변수 중 분해 가능한 유기탄소 비율(DOC)과 메탄으로 전환 가능한 DOC 비율($DOC_f$)은 국내 폐기물의 조성별 특성을 반영할 수 있도록 국내 연구결과를 이용하여 기준값을 도출하여 사용할 수 있으며, 메탄보정계수(MCF)는 매립시설의 설계나 설치 등의 단순한 기준으로 판단할 수 없으므로 명확한 기준이 요구되는 것으로 나타났다.

  • Post-kyoto regime has been discussing with the GHG reduction commitment. GHG energy target management system also has been applied for the domestic measures in the country. Universities are major emission sources for GHG. It is very important for campus to built the GHG inventory system and estimate the potential GHG emission reduction. In general, GHG inventory on the campus was taken by the IPCC guidance with the classification of scope 1, 2, and 3. Electricity was the highest portion of GHG emission on the campus as 5,053.90 $tonsCO_2eq/yr$ in 2009. Manufacturing sector was the second high emission and meant GHG in laboratory. Potential GHG reduction was planned by several assumptions such as installation of occupancy sensor, exchanging LED lamp and photovoltaic power generation. These reduction scenarios was simulated by LEAP model. In 2020, outlook of GHG emission was estimated by 17,435.98 tons of $CO_2$ without any plans of reduction. If the reduction scenarios was applied in 2020, GHG emission would be 16,507.60 tons of $CO_2$ as 5.3% potential reduction.

  • This research shows the improved methodology which can be applied for universities which want to set up their GHG inventories. In other words, we tried to make guideline in problems due to the unique characteristics of universities. This guideline will help university to deal with the problems they are facing: For example university has less enforcement in operational control compared to the business sector. And it also has various usage of facilities, although these facilities are not maintained by same principal agent. The difference between owner and manager is an another reason for difficulty in setting group organization. The improved and adaptable methods responding to these problems were suggested from this research. The results of this research says the new definition of function for various actors in university for quality control and quality assurance. Because the suggestions made in this research which concerns with criteria for building of universities' GHG inventories were all read by current legislation, there is an anticipation that this can be an official guideline that can be applied to the universities right away.

  • Climate change has been identified as one with the greatest challenges facing nations, government, business and over future decades. Activities to reduce greenhouse gas emissions by the Kyoto Protocol, the international community has been in progress. Korea also has introduced the Emission trading system to reduce greenhouse emission from the supervision of the government. Greenhouse gases emissions quantity should be internationally recognized. Mutual Recognition Arrangement should be recognized as the same greenhouse gas emission. International recognition of domestic verification body of international mutual recognition is required. Efforts are needed to secure the equivalence between the emission rights through direct cooperation with the relative nation accreditation body. Early entry into the IAF/PAC GHG MLA is essential for demonstrating equivalence between greenhouse gas emissions. Emissions trading will also require connection to the EU ETS, California, USA, and Tokyo, Japan to link Emissions trading. In the case of establishing accreditation standards and accreditation criteria, it will be necessary to distinguish between the domestic Energy Target Management System and the Emission Trading System. Independent greenhouse gases verification bodies should be established to meet the requirements of IAF and PAC. It is necessary to revise the qualification criteria for the verification of the greenhouse gas verification body according to international standards requirements. It is necessary to support the role of accreditation bodies of domestic greenhouse gas verification bodies. It is required to join international organizations of international mutual recognition of international trade and the need for pilot projects to link greenhouse gas emissions. The core link to our emission trading system is called EU-ETS, and we will need to join the IAF/PAC GHG MLA GHG. The International Mutual Recognition Agreement (IAF) is expected to allow international interoperability of GHG emissions verification between EA and the PAC. By signing a PAC GHG MLA, it will need to be prepared to prepare for the pilot project to link the emission trading system.

  • 2011년부터 온실가스 에너지 목표관리제와 같은 국가적 온실가스 감축 규제가 대학에도 적용되기 시작하면서 2000년대 급속한 증가를 보이는 것으로 알려졌던 대학의 온실가스 배출량은 2011년 이후 안정세 및 하락세를 보여 오고 있다. 따라서, 온실가스 배출 규제의 시행을 계기로 대학사회가 온실가스 에너지에 대한 관리를 강화하고 있고 그 효과가 나타나고 있다고 이야기할 수 있게 되었다. 특히, 보다 강력한 제도적 속성을 지닌 배출권거래제 시행 준비 시기에는 총량이 줄어드는 결과를 보이는 등 온실가스 다배출 대학을 중심으로 감소하는 추세로 전환되었다고 평가할 수 있다. 본 연구에서는 개별 대학의 온실가스 감축 활동을 세부적으로 추적하지는 않았지만 온실가스 배출에 영향을 끼치는 주요 활동도 자료를 분석하였고, 그 결과 대학의 온실가스 배출이 2011년 이전에는 연구수혜액, 그리고 2013년 이후에는 연면적의 변화가 영향을 주는 것을 확인하였다. 이에, 향후 대학의 온실가스 감축 목표 설정 원단위는 연면적을 기준으로 하는 것이 바람직하다고 판단되며, 보다 체계적인 대학의 온실가스 감축을 지원하기 위한 면적 단위 온실가스 배출량의 기준 수립과 관련 정보 공유가 필요하다고 할 수 있다.
