In this research, through LCA analysis, the environmental impact of automotive engine manufacturing and re-manufacturing was analyzed from the perspective of the entire process, and the greenhouse gas reduction effect was calculated based on this. The amount of greenhouse gas emitted from the process of acquiring and manufacturing raw materials for automotive engines is about 3,473 kg for new manufacturing and 872 kg for re-manufacturing. Thus, the amount of greenhouse gas reduction by engaging in re-manufacturing is about 2,601 kg; the analysis shows a reduction effect in each part of the entire process except for the processing stage. As a result of the LCA weighted analysis, the environmental impact of new product manufacturing was found to be 1.07E+03 Eco-point, and it was 2.67E+02 Eco-point for re-manufacturing. The share of GWP(Global Warming Potential) among the six major impact categories(Abiotic Depletion Potential, Acidification Potential, Eutrophication Potential, Global Warming Potential, Ozone-layer Depletion Potential, Photochemical Oxidant Creation Potential) as high at 99.72%(new manufacturing) and 99.68%(re-manufacturing).

최근 지구온난화로 인한 환경 문제의 심각성이 증가하고 있다. 이에 전 산업 부문에서 지구온난화에 가장 큰 영향을 미치는 온실가스 배출량에 대한 규제를 강화하고 있다. 건설 산업에서도 온실가스 저감 대책으로 친환경 에너지 개발, 친환경 건축물 인증제도등 녹색기술의 활동이 활발히 진행 중에 있다. 그러나 이러한 활발한 연구와 노력에도 불구하고 건설공사의 각 단계별 과정에 따른 온실가스 배출량과의 이해관계를 파악하기에는 어려움이 있다. 따라서, 본 논문은 기존 연구문헌을 조사하여 건설공사 과정을 원자재 생산, 시공, 유지 및 관리, 해체 및 재활용의 단계로 구분하여, 건설공사의 각 단계에서 온실가스 배출량에 영향을 미치는 요인을 도출하고, 시스템 다이내믹스의 인과지도 작성을 통하여 온실가스 배출 원인을 분석하였다.

IT 산업은 친환경적이라는 일반적인 인식과 달리 IT 기기의 생산, 사용, 폐기 과정에서 유해물질 유출 및 온실가스 배출 등의 다양한 환경 문제를 유발한다. 특히나 IT 산업은 모든 산업의 조달, 생산, 유통 효율화에 핵심 역할을 담당하고 있기 때문에 저탄소 IT 기술의 도입은 전 산업의 에너지소비감축 및 온실가스 저감을 이끌어낼 수 있다. 따라서 본 논문에서는 2009년 최고의 화두인 저탄소 IT 기술의 개요와 필요성을 알아보고, 국내외 추진되는 저탄소 IT 기술의 정책동향을 살펴본다. 그리고 향후 글로벌 시장을 선점하기 위해 기업들이 내놓은 IT 기기 및 장비를 위한 탄소 저감 및 관리 기술들에 대해 알아본다. 다음 기술들은 눈에 보이지 않는 탄소배출량을 기술적으로 측정해 이를 가시화하고, 관련 데이터를 분석하여 실질적인 저감 계획을 세움으로써 지구온난화를 해결할 수 있는 최적의 대안으로 제시되고 있다.

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.

This paper estimate the $CO_2$ reduction potential that can be achieved by improving the technical efficiency of input factors in the manufacturing sector. Technical efficiency in each manufacturing firm was estimated using the DEA technique. Depending on the returns-to-scale assumption selected, average technical efficiency was estimated to be between 0.467 and 0.643. These estimates suggest that, when the efficiency of electricity consumption in the manufacturing sector is improved, the overall $CO_2$ emissions can be reduced by 17.1-25.5%. Recently, the Korean government has adopted a low-carbon-green-growth policy with the goal of reducing greenhouse gas emissions by 30% below the BAU level by year 2020. The analysis of the paper suggests that this goal can be achieved through improved efficiency of electricity consumption.

In accordance with the global efforts to reduce greenhouse gas emissions, Korean government submitted its INDC (Intended Nationally Determined Contribution) of 25.7% for domestic reduction and the total of 37% reduction by 2030 including the purchase of emission reduction permit from abroad. In this study, 25.7% reduction target is being evaluated to see its impact on domestic energy system using the integrated assessment model, GCAM (Global Change Assessment Model). Results show that electricity generation from fossil fuel technologies using coal and gas decrease by 28.0%, 13.5% while that of biomass, wind power, solar energy increase by 47.6%, 22.0% and 45.4%, respectively. It is worth noting that so called new technology such as USC (ultra supercritical power generation) does not contribute to achieving the emission reduction target and careful and quantitative analysis is required for such categorization in the future.
