As carbon neutrality becomes an issue around the world, research is actively being conducted to achieve reduction targets for each industry by declaring 2050 carbon neutrality in Korea and implementing the greenhouse gas target management system and emission trading system. The construction industry quantitatively predicts and evaluates carbon emissions by stages through the evaluation of the entire building process, but research on this is insufficient in the case of the construction process. Therefore, as part of the research on predicting and reducing carbon emissions generated at construction sites, data from actual construction sites were collected to analyze the facilities and characteristics of each energy source, and a scenario was proposed to quantitatively predict the use of each energy source.

The cap-and-trade system against the air pollutants in the Seoul Metropolitan Area (SMA), Korea has been implemented since 2008 and will be implemented other areas in Korea on 2020. In this study, to identify the outcome and effectiveness of the cap-and-trade system in the SMA, (1) the rate of change for NOx and SOx emissions, (2) differences between the real emission and allocated amount, and (3) the status of trading are reviewed. It was found that the NOx and SOx emissions from the sources under the cap-and-trade system decreased in the SMA but the reduction was mainly due to the reduction of fuel usage not related to the system. It was found that the average percentage of annual emission in the SMA to the allocated amount between 2008 and 2018 was 66.9% for NOx and 69.3% for SOx, respectively. It suggests that there was over allocation of the emission amounts. The average trading prices in the SMA were 0.193 $/kg for NOx and 0.128 $/kg for SOx, far lower than those in RECLAIM, 131.942 $/kg and 81.677 $/kg, respectively. It was suggested that (1) the cap system for NOx and SOx emissions should be implemented only for the area with high emission ratio from large point sources, (2) the trade system is not suitable for the effective implementation of the cap system, and (3) Korean government should not allow over allocation in order to ensure sound market function without delaying the introduction of technology.

배출권거래제는 대표적인 기후정책으로 온실가스 총배출량의 87%(2021년 기준)에 대한 감축 유인체계를 형성한다. 상당량의 감축이 기대되는 가운데 배출권가격 변동이 경제, 에너지 및 환경 부문에 미칠 파급 효과에 대한 심도있는 이해가 필요하다. 본 고는 거시계량 기반 연립방정식 모형을 통해 배출권거래제의 정책효과를 분석한 국내 최초의 연구로, 한국표준산업분류(경제), 에너지밸런스(에너지), 국가온실가스인벤토리(환경)를 연결해 현실 설명력을 제고한 데 의의를 지닌다. E3 동학에 대한 분석결과에 따르면 4년에 걸친 배출권가격의 50% 인상 충격은 온실가스 배출량 감소(-0.043%)와 함께 주요 거시변수인 실질GDP(-0.058%), 민간소비(-0.003%) 및 투자(-0.301%) 등의 하방 이동으로 귀결된다. 배출권가격의 인상은 온실가스 감축목표 달성의 필수불가결한 요소로, 가격 인상 충격에 따른 이행리스크에 대응함으로써 거시 경제의 지속가능성을 담보하기 위해 경매수익을 활용한 세수환원 방안을 검토할 수 있다. 본 연구는 법인세 경감 및 경상이전지출 확대 등 세수환원 수단 중 성장 측면에서 후자의 정책 비교우위를 확인했다.

Purpose - This paper examines South Korea's potential status as a carbon leakage country, and the level of risk posed by the Korean emissions trading scheme (ETS) for Korean industries. The economic effects of border carbon adjustments (BCAs) to protect energy-intensive Korean industries in the process of achieving the carbon reduction target by 2030 through the Korean ETS are also analyzed. Design/methodology - First, using the Korean Input-Output (IO) table, this paper calculates the balance of emissions embodied in trade (BEET) and the pollution terms of trade (PTT) to determine Korean industries' carbon leakage status. Analyses of the risk level posed by carbon reduction policy implementation in international trade are conducted for some sectors by applying the EU criteria. Second, using a computable general equilibrium (CGE) model, three BCA scenarios, exemption regulations (EXE), reimbursement (REB), and tariff reduction (TAR) to protect the energy-intensive industries under the Korean ETS are addressed. Compared to the baseline scenario of achieving carbon reduction targets by 2030, the effects of BCAs on welfare, carbon leakage, outputs, and trading are analyzed. Findings - As Korea's industrial structure has been transitioning from a carbon importing to a carbon leaking country. The results indicate that some industrial sectors could face the risk of losing international competitiveness due to the Korean ETS. South Korea's industries are basically exposed to risk of carbon leakage because most industries have a trade intensity higher than 30%. This could be interpreted as disproving vulnerability to carbon leakage. Although the petroleum and coal sector is not in carbon leakage, according to BEET and PTT, the Korean ETS exposes this sector to a high risk of carbon leakage. Non-metallic minerals and iron and steel sectors are also exposed to a high risk of carbon leakage due to the increased burden of carbon reduction costs embodied in the Korean ETS, despite relatively low levels of trade intensity. BCAs are demonstrated to have an influential role in protecting energy-intensive industries while achieving the carbon reduction target by 2030. The EXE scenario has the greatest impact on mitigation of welfare losses and carbon leakage, and the TAF scenario causes a disturbance in the international trade market because of the pricing adjustment system. In reality, the EXE scenario, which implies completely exempting energy-intensive industries, could be difficult to implement due to various practical constraints, such as equity and reduction targets and other industries; therefore, the REB scenario presents the most realistic approach and appears to have an effect that could compensate for the burden of economic activities and emissions regulations in these industries. Originality/value - This paper confirms the vulnerability of the Korean industrial the risk of carbon leakage, demonstrating that some industrial sectors could be exposed to losing international competitiveness by implementing carbon reduction policies such as the Korean ETS. The contribution of this paper is the identification of proposed approaches to protect Korean industries in the process of achieving the 2030 reduction target by analyzing the effects of BCA scenarios using a CGE model.

Studies on the regulation and measurement of greenhouse gases(GHGs) emissions have been carrying out for global wanning. In order to reduce greenhouse gas emissions, many countries have been promoting the Emissions Trading System and projects of the Joint Implementation(JI) and Clean Development Mechanism(CDM). These country's GHG emissions have been measured calculation criteria based on the Intergovernmental Panel on Climate Change(IPCC) Guidelines. In order to respond to GHGs regulation, in each country, it is planing to build a Low-Carbon City. The system has been developed for calculating GHGs emissions from companies and institutions in their respective countries. However, the system can monitor the GHGs per city, has not been developed. In this paper, it is studied to design the User Interface and to develop integrated monitoring program for Low-carbon city. This program will make possible monitoring and management, statistics, and reports written by using each data in units of cities.

Globally, South Korea is a country that has a lot of $CO_2$ emissions and has steadily increased its total greenhouse gas emissions since the 1990s. With the recent implementation of the carbon emission trading system in Korea, the importance of calculating $CO_2$ emissions of construction equipment is increasing, hence the need for accurate calculation of environmental penalties through allocating carbon emission rights. This study presents a methodology to predict the price of carbon credits using big data analysis method. This methodology is based on correlating and regression analysis of trends in carbon emission prices and search volumes. This study aims to support faster and more accurate budget calculations in the planning of the construction process based on the predicted price of carbon emission rights.

"온실가스 배출권의 할당 및 거래에 관한 법률"과 "제1차 기본계획"에 의하면 거래제도의 설계 시, 제도 도입에 따른 기업의 시장지위 변화를 최소화하는 방향으로 이루어져야 한다. 본 연구는 쿠로노 복점에 기초한 이론모형 분석을 통해 배출권의 회계처리 방식에 따라 기업의 자본 부채 비율, 자본비용, 그리고 기업의 시장지위가 변할 수 있으며, 그 결과 사회후생효과 측면에서 차이가 발생할 수 있음을 보여준다. 분석결과에 따르면, 1기 배출권거래제의 할당방식(무상할당)과 가장 보편적으로 이용되는 회계처리방식(무상할당된 배출권을 무형자산으로 인식하고 그 가치를 0으로 계상하는 방식)이 결합될 경우, 기업의 시장지위에 미치는 영향을 최소화할 수 있다. 이어지는 분석을 통해 본 연구는 이 방식이 자산시장을 통해 감축신호가 기업에 전달되지 않으면서 거래제도의 도입목적인 비용효과적 감축에는 한계를 가진 회계처리방식임을 보여준다.

Kyoto Protocol is an international convention on concrete performance program for UNFCCC(United Nations Framework Convention on Climate Change), which regulate and prevent to global warming and officially came into effect on February 16, 2005. Kyoto flexible mechanisms, the agreed environmental system in March 1997 in the Third Conference of Parties in UNFCCC General Assembly, Emission Trading System(ETS), Clean Development Mechanism(CDM) and Joint Implementation(JI), are key policies related to environment. In advanced countries, greenhouse gas emissions should be reduced average 5.2% level compared to 1990 in total emissions during 2008-2012. World leading carbon market finished the trial on the EU ETS I greenhouse gas emissions trading system, EU ETS II is operated regularly after 2008. World Bank leads to make 'Prototype Carbon Fund(PCF)' in April 2004, which is the world first carbon fund and a representative public carbon fund type, World Bank operate various funds including present PCF. Thus, I would like to propose as follows in relation to this study: First, in the validity analysis of carbon funds, it would be needed to analyze the Emission Reduction Cost Efficiency(ERCE) of carbon. The ERCE is a break-even value which brings the Net Present Value(NPV) to zero. NPV approach is used among projects and it enables potential projects to be compared and evaluated the ERCE on the basis of the net present value of net future cash flows. Therefore, according to results of analysis, carbon funds should be developed and invested. Second, it would be necessary to allow of issuing bonds together with carbon funds, carbon finance etc. Third, carbon funds, it would be reasonable to have a relatively enough maturity in project and as a financial derivatives in the international financial markets, it is needed various types of transactions. Fourth, it would be needed to standardize the carbon emissions trading for more efficiently. Fifth, it would be necessary to establish and invest in various kinds of domestic and overseas global carbon funds, including governments, privates, governments and privates sectors. And it is also needed to establish the medium and long term plans for carbon funds. Sixth, it would be needed to foster the advanced trade mechanisms for carbon funds in the most effective ways. Finally, carbon funds should be used in harmony with international societies to reduce global warming as the social responsible investing funds and it should be contribute to sustainable development. In addition, it would seem that carbon funds should be studied on establishing the contributable standard of sustainable development in the future assignment.

배출권거래제는 온실가스 감축과 저탄소 사회로의 전환을 위한 핵심 정책이다. EU 배출권거래제(EU ETS)는 운영기간, 핵심 설계 노하우 등에서 국내 배출권거래제보다 앞서 있는 좋은 벤치마크 대상이다. 이에 본 연구는 EU ETS 4기의 주요 제도 설계를 배출허용총량(Cap), 배출권 무상할당방식, 유·무상할당업종 선정 방식, 시장안정화 조치, 감축지원제도 등을 중심으로 살펴보았다. 그리고 EU ETS 1-4기의 주요 설계와 주요 설계 변경이 향후 국내 배출권거래제의 설계 및 운영에 미칠 영향을 각각 분석해보았다. 우선, 국내 배출권거래제 설계에 대한 영향으로는 벤치마크 갱신 방안 마련, 국내 산업구조 및 특성을 반영한 무상할당업종 선정 기준 마련과 2단계 평가 도입, 경매 수익의 구체적 활용방안 마련의 세 가지 요구가 증대될 것으로 예상된다. 다음으로 향후 배출권거래제 운영에 미칠 영향으로는 제도 개정의 객관적이고 심도있는 영향평가, 계획 및 제도 개정의 이른 확정을 통한 제도 안정성 및 대응 기회 제공, 배출권 거래제 거버넌스 조정 및 이해관계자 참여 확대 유도 세 가지를 들 수 있다.

본 연구는 개별 국가 혹은 지역 단위 배출권 거래제도의 국제적 연계 가능성에 대비하기 위해 한 중 일 3국간의 배출권 거래제도 연계 시 예상되는 경제 환경적 영향을 분석하기 위해 수행되었다. 이를 위해 연산가능 일반균형모형을 통해 3국간 배출권 거래제 도입의 경제 환경적 영향을 분석하였다. 분석결과 한 중 일 3국간 탄소시장의 연계는 국가별로 다양한 측면에서 복잡한 영향을 미치게 됨을 확인할 수 있다. 한 중 일 배출권 거래제 연계 시행은 3국 전체의 실질 GDP를 증가시키는 긍정적 효과가 있음에도 불구하고 연계로 인한 이익의 국가간 분배가 불균형적임은 물론 실질 소비나 고용 등의 측면에서는 탄소시장 연계가 3국 전체적으로도 오히려 부정적인 영향을 초래할 수 있다는 점에서 반드시 긍정적인 효과만을 담보하는 것은 아니다. 특히 배출권 매입국인 한국과 일본의 소득 소비 고용 감소 및 에너지 의존도 증가, 배출권 매출국인 중국의 생산 감소 및 해외 이전 가능성은 3국간 탄소시장의 연계의 장애요인으로 작용할 수 있다. 3국간 탄소시장 연계를 통한 긍정적 효과를 최대한 유지하면서 예상되는 부정적 효과를 최소화하기 위해서는 배출권 수입 관세나 수입배출권 할인과 같은 보완적 정책수단의 개발 적용이 필요하다.
