After the Kyoto Protocol has been ratified in Feb. 16 2005, the developed countries which is involved in Annex-1 have tried to mitigate GHG to the reduction objective. To accomplish this objective, EU developed EU-ETS, CDM project, and so on. Korea has faced pressure to be a member of Annex-1, because Korea and Mexico are only non-Annex-1 countries in the OECD nations. In this study, we simulated power plant expansion plan and calculated $CO_2$ emission with changing Carbon Tax. Especially, we focused on the competitiveness of IGCC and carbon capture technology. In our result, even though carbon tax rise, nuclear power plant does not always increase, it increase up to minimum load. LNG combined cycle power plants substitute the coal fired power plants. If there are many alternatives like IGCC, these substitute a coal fired power plant and we can reduce more $CO_2$ and save mitigation cost.

In this study, consumption-based greenhouse gas emissions from 1990 to 2021 are calculated by the industry sector, and greenhouse gas emissions transferred due to trade between countries are compared to analyze what implications Korea has. As a result, production-based and consumption-based emissions in the United States, Germany, the EU, and the OECD are gradually decreasing. Production-based emission in Korea is larger than consumption-based emissions because Korean economic structure is import-oriented. However, unlike other developed countries, Korea cannot trade energy by land, so it can be said that it is reasonable to establish a greenhouse gas reduction plan considering Korea's unique characteristics.

한국의 ESCO업체들이 에너지사용 및 온실가스 생산을 절감하는데 있어 중요한 역할을 할 것이라고 생각한다. ESCO사업이 성장하고 강력해질수록 프로젝트 수행에 있어 장애요인을 제거하는데 더욱 효과적일 것으로 본다. 따라서 우리의 첫번째 목표는 한국에서 에너지를 절약하고 온실가스를 저감시킬 수 있는 ESCO사업이 성장하도록 돕는 것이다.

Many countries have implemented a variety of climate and energy policies to reduce greenhouse gas emissions and expand renewable energy production. The ultimate goals of those policies are associated with transition to a low-carbon economy that aims to combat climate change and economic growth. This study aims to examine empirically if the countries which implement overlapping climate policies and renewable energy policies show additional reduction of the GHG emissions than the countries which implement single climate or renewable energy policy. The result shows that overlapping policies contribute to reduce additional GHG but not all cases. In particular, only overlapping policies mixing 'ETS and RPS(renewable portfolio standards)' and 'Carbon Tax and FIT(Feed-in Tariff)' can lead to additional reduction of GHG emissions.

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.

서울특별시는 지구온난화 방지를 위한 국제적인 온실가스 감축 노력의 일환으로 공공기관을 중심으로 신재생에너지 보급 사업을 추진중에 있다. 서울시는 이 사업을 추진하면서 대기오염물질 저감과 더불어 연간 1만2162톤 $CO_2$ 정도의 온실가스 감축효과로 연간 2억1800만원을 절약하고, 향후 10년간 총 21억8900만원에 이르는 경제적 부가가치가 창출될 것으로 전망했다. 현재 서울시에는 공공기관, 학교 등에 태양광, 태양열 등 신재생에너지 시설이 총 297개(2009년 기준, 가정집 제외) 기관에 설치되어 있다. 이는 연간 약 522만9812kg의 온실가스를 저감한 것으로 어린 소나무로 환산하면 약 188만2732 그루를 심는 환경효과가 있다. 본지는 서울시 녹색서울 시민위원회와 에너지나눔과 평화에서 지난 2007년부터 조사한 자료를 바탕으로 정부의 신재생에너지 정책 및 서울시 신재생에너지 설치 현황에 대해 소개한다.

This paper analyzes the relationships among the energy consumption, renewable energy production, real gross regional domestic product(GRDP), and greenhouse gas(GHG) emissions. It uses the metropolitan city and province level data for Korea from 2010 to 2018, employing a panal vector autoregressive(VAR) model. We find that an increase in energy consumption has a limited impact on boosting renewable energy production or gross regional domestic product, while it leads to an increase in greenhouse gas emissions. A rise in renewable energy production can increase gross regional domestic product, but it has no meaningful effects on energy consumption and the reduction of green house gas emissions. Our finding indicates that it is crucial to expand the supply of renewable energy as well as to decrease energy consumption in order to achieve the goal of reducing greenhouse gas emissions and reaching economic growth.
