The growing amount of using the fossil fuel is bringing about environmentally, economically serious problems like as global warming. To solve the problems, the international society has begun to decrease greenhouse gases through the international agreement like as the climate change convention. In South of Korea, it was presented practical goal of Green Development try to decrease greenhouse, which is the future 60 years vision. And, it contains the strategies of Green Development and 5th Plan of Green Development. Nowadays, the government accepted the active alternative scenario 3, which is the goal of 4% decrease in greenhouse gases until 2020's, presented by Presidential Committee on Green Growth. This study established the strategies of Transport Demand Management to decrease the greenhouse gases in transportation part, and then we measured the effect of them. As a result, if it takes effect the aggressive strategies annually, it will cut greenhouse gas pollution by 3.1%, which is 7,590,000t$CO_2eq$, in transportation part. So, we can expect that it would be the effective policy tool to achieve the goal of government, which is the Green Development, if it controls the strategies of TDM effectively by the political needs.

우리나라는 저탄소 녹색성장을 위한 국가 온실가스 감축목표 즉 2020년까지 BAU 대비 30% 감축을 달성하기 위해 총량제한 배출권거래제를 도입하는 "온실가스 배출권의 할당 및 거래에 관한 법률"이 2012년 5월 14일 제정됨에 따라 2015년 1월 1일부터 온실가스 배출권거래제가 본격 시행된다. 배출권거래제를 통해 기업은 온실가스 감축에 소요되는 비용부담을 줄일 수 있고 그 만큼 산업경쟁력 확보가 가능하게 된다.

2007년이면 온실가스 배출통계 시스템 구축이 완료된다. 산자부는 에너지∙산업공정부문 배출통계 작성, 관리에 관한 법적근거를 에너지기본법에 신설하고, 『온실가스통계 DB구축 추진협의회』를 구성, 온실가스 인벤토리시스템(KONIS：Korean National Inventry System)을 구축한다. 또한 산업, 가정∙상업, 수송부문 최종소비단계의 온실가스 배출량 조사를 추진하여 국가에너지종합정보DB를 구축한다. 산자부는 온실가스통계 체계 구축을 통해 기술적, 경제적 감축잠재량을 분석하고, 정부-산업계가 수용 가능한 수준의 자발적 감축규모를 산정할 계획이다. 이를 통해 Post-2012 국제협상에 대비한 우리나라 대응전략을 수립하고, 산업계의 기후변화협약 대응능력과 조기감축 노력을 촉진할 수 있을 것으로 기대한다.

The potential mitigation of greenhouse gas (GHG) is studied in the Pohang steel industrial complex (PHSIC). The total GHG emission in 2010 is estimated to be in the range from 4,174,000 to 4,574,000 $tCO_2-eq$ in PHSIC. To meet the target proposed by the government, it is needed to reduce 552,000 $tCO_2-eq$ at minium by 2020. To estimate the potential amount of GHG reduction, the technologies used in the voluntary carbon reduction projects are applied to 51 companies which are subject to GHG target management. From the viewpoint of technological availability and payback period, the fuel conversion and waste heat recovery have an advantage in the short term with a possibility to reduce 160,000 $tCO_2-eq$. In the mid term, the thermal technologies in steel and iron industry have the potential to cut 229,000 $tCO_2-eq$, while the electrical technologies have the potential of 125,000 $tCO_2-eq$ reduction. The gap between the target GHG mitigation and potential reduction using the short and mid term technologies is about 38,000 $tCO_2-eq$, which should be compensated by the fundamental process innovation and the implementation of the most cutting-edge technologies including renewable energy.

Although market stabilization measures have been triggered in the K-ETS, carbon price is still under uncertainty. Considering Korea's 2030 enhanced reduction target announced in October 2021, it is crucial to have practical stabilization measures to appropriately deal with price uncertainty. This study examines the quantitative effects of a price collar, which is considered as a means of alleviating price uncertainty, on expected cumulative emissions and abatement costs. There are three main scenarios: carbon tax, emissions trading system, and emissions trading system with a price collar. Monte Carlo simulation was conducted to reflect uncertainty in emission. There are several results as follows: 1) In a price collar, domestic emission target is likely to be achieved with a lower expected abatement cost than other scenarios. In addition, there is a small amount of excess emissions in this research and it would be not critical(0.1% excess than target); 2) Prohibiting banking increases the expected abatement cost. This is because firms can not intertemporally reallocate allowances to match the firm's optimal emissions path; 3) With the adoption of a price collar, government's net revenue can be positive even if the government's purchase volume of emissions allowances is more than sales volume. This is because the government sells them at price ceiling and purchases them at price floor.

세계는 기후 위기, Covid-19에 직면함에 따라 물 산업 분야 탄소감축에 대한 목소리가 높아지고 있다. GWI(Global Water Intelligence)에서는 2030 물 분야 탄소감축 목표를 달성하기 위하여 17억 8,500만 달러, 노후자산 교체를 위한 신규 인프라 건설에 40억5600만 달러의 비용이 들 것으로 추산하였다. 이에 본 연구는 국내 물산업의 탄소중립 목표 달성을 위한 물 기업 혁신 전략 마련에 앞서 '영국 물 산업 2050 혁신 전략' 사례를 고찰하였다. '영국 물 산업 2050 혁신 전략'은 물 산업의 변화를 자극하고 장기적으로 고객과 환경, 그리고 국제사회에 이바지하는 것을 목표하고 있다. 본 전략은 현재와 미래에 제공할 물 서비스에 영향을 미치는 주요 요인과 이해관계자의 요구(Needs)에 집중한다는 특징이 있다. 문제점에 대한 시스템적 관점을 취하면서, 물 부문이 더 넓은 사회적 요인(물, 식량, 에너지 등)에 대해 대응할 수 있는 역할을 제고하기 위함이다. 결과적으로, 산업 인프라 및 환경 관련 다양한 부문 간 협력에 의한 시너지 창출은 온실가스 배출 'Zero'(2050년) 목표 달성에 한발 다가설 것으로 기대되며, 에너지, 제조, 데이터 과학, 식량 안보, 생태 복원 등의 분야는 물 산업 간 연계성이 높아 물 분야 혁신의 기회로 작용할 것으로 예상된다. 본 연구는 물 산업 혁신 전략으로 첫째, 중장기적인 혁신을 제공할 수 있는 통합 혁신 센터를 설치하여 인적·물적 자원을 네트워크화하는 방안을 제시하였다. 둘째, 물 분야 데이터 개방을 통하여 일반, 학계, 중소기업, 스타트업 등과 공동성장 지원을 제시하였다. 셋째, 다양한 물 문제와 경영 의사결정에 환경성을 고려할 것을 제시하였다.

배출권거래제가 내년 1월부터 시행될 예정이다. 이에 기업들은 실제 온실가스 배출증가 추세와 신 증설 시설 투자계획 등을 고려한 현실적인 할당이 이루어지길 원하며 정부는 국가 감축목표 달성이 가능하도록 할당량을 결정하고자 한다. 온실가스 감축목표는 다양한 정책의 종합결과물로서 에너지정책, 산업발전정책, 온실가스 감촉기술발전 추이 등이 종합적으로 고려되어야 한다. 배출권거래제의 안정적 운영과 지속적인 경제성장을 담보하기 위해서라도 환경보전과 산업경쟁력을 동시에 고려하는 합리적 대안이 마련되기를 희망해 본다.

Since the release of mid-term domestic GHG goals until 2020, in 2009, some various GHG reduction policies have been proposed to reduce the emission rate about 30% compared to BAU scenario. There are two types of modeling approaches for identifying options required to meet greenhouse gas (GHG) abatement targets and assessing their economic impacts: top-down and bottom-up models. Examples of the bottom-up optimization models include MARKAL, MESSAGE, LEAP, and AIM, all of which are developed based on linear programming (LP) with a few differences in user interface and database utilization. The bottom-up model for electric sector requires demand management, regeneration energy mix, fuel conversation, etc., thus it has a very complex aspect to estimate some various policies. In this paper, we suggest a bottom-up BAU model for electric sector and how we can build it through step-by-step procedures such that includes load region, hydro-dam and pumping storage.

As GHG target management is introduced in Korea, designated establishment takes responsibilities to reduce more than 30% of expected GHG emission until 2020. Although decreasing GHG has been requested to universities which consume great amount of energy, there are difficulties to apply high cost countermeasures. Therefore, this research suggest a low cost, easily-applicable energy saving method, and derive potential GHG reduction amount in the case of SNU, Kwan-ak campus. First of all, 11 rooms of different use were chosen as the samples, and energy consumption in each room was measured. Standard models for each room were built through researching on the electric devices in each room. Moreover, energy consumption was computed for each devices through analyzing the pattern of electricity consumption. 32 GHG reduction technology and action program were chosen, and they were applied to the standard models for individual rooms. Through multiplying energy reduction rate of each program to energy consumption of each electric device, maximum energy reduction of each electric device is derived. Through that, Maximum GHG reduction for individual rooms and each month and the total GHG reduction capacity of Kwan-ak campus were computed. It was found out that approximately $5,311tCO_2$-eq can be reduced, when reduction technology and action program suggested by this research are applied. It appeared 24.48% of requested reduction amount to SNU can be reduced, till 2016.

A marginal abatement cost analysis has been conducted to analyze the effects of abatement measures on greenhouse gas (GHG) emissions for the Korean residential sector. A bottom-up model using MESSAGE has been developed by defining the energy demand and constructing the reference energy system for the residential sector. A great amount of activity data has also been analyzed. Abatement potentials and related costs of individual abatement measures are investigated. The result from the marginal abatement cost analysis may provide general guidelines and procedures for the establishment of GHG abatement polices.
