In this study, the newest technology available to reduce GHG emissions, which can be applicable in energy industries of the future that has large reduction obligations by energy target management and large intensity of GHG emissions, has been investigated by searching the technical characteristics of each technology. The newest technology to reduce GHG emissions in the field of power generation and energy can be mainly classified into the improvement of efficiency, CCS, and gas combined-cycle technology. In order to improve the reliability of the GHG emission factor obtained from the investigation process, it has been compared to the technology-specific GHG emission factor derived from the estimated amount of emissions. Then the GHG abatement measures, using the derived estimation of factor, by using the newest technology to reduce GHG emissions have been predicted. As a result, the GHG reduction rate by technology of CCS development has been expected to be the largest more than 30%, and the abatement rate by technology of coal gasified fuel cell and pressurized fluidized-bed thermal power generation has been showed more than 20%. If the effective introduction of the newest technology and the study of its characteristics is continued, and properly applied for future GHG emissions, it can be prospected that the national GHG reduction targets can be achieved in cost-efficient way.

온실가스 감축목표의 달성을 위한 정책은 에너지 가격구조의 개선을 통해 국가 경제의 탄소 집약도를 낮추고 에너지 효율을 제고하는 방향으로 추진되어야 할 것이다. 우리나라는 대규모 배출권에 대하여 배출권 거래제를 시행하고 있으므로, 이를 보완하는 차원에서 배출권 거래제의 적용을 받지 않는 배출원에 대하여 탄소세를 부과하는 정책을 추진할 필요가 있다. 온실가스 감축을 위한 규제(탄소세, 배출권 거래제 등)는 기존세제 구조의 왜곡을 해소하거나 교역조건 개선 효과가 클 경우 경제성장에도 긍정적 영향을 미칠 수 있다.

The goal of this study is to analyse the effects of financial support by governmental on KERRP (Korea Emission Reduction Registration Project) in the case of descending clock auction. Result shows that about 60% of total reduction (612,000ton) can be achieved at the price of 8,000 Won/ton with the budget amount of 5 billion Won, if the benefit from energy saving by the project is not included. Also 100% of total reduction (1,015,713ton) can be achieved at the price of 4,900Won/ton, if the benefit from energy saving by the project is included. Because most projects get some benefits from the energy saving occurred by project performance, the financial support by government may not be needed. However, this type of support would be meaningful from the aspect of encouraging GHG (Green House Gas) reduction to be prepared for the potential obligation of national GHG reduction from 2013.

The International Maritime Organization (IMO) has been seeking measures to prevent climate change caused by shipping and actively discussing the initial strategy of reducing ship greenhouse gas emissions adopted in 2018. Member states are proposing various reduction measures in the IMO's 5th International Working Group on the Reduction of Greenhouse-gas emissions. However, each member country's method of measuring impact assessment differs, making it impossible to objectively compare impact assessment by country. As such, various measures have been proposed by each country to reduce greenhouse gas emissions, and it is necessary to determine a standard impact assessment measurement method that can be applied to all countries before 2023, when IMO's greenhouse gas reduction strategy is implemented. Therefore, this study seeks to develop detailed guidelines for impact assessment to objectively compare the impact assessment results of ships' greenhouse gas reduction measures. Drawing detailed guidelines that can compare the effectiveness of each country's reduction strategies will enable the IMO leading marine environment GHG reduction.

온실 가스 배출로 인하여 지구 온난화 문제가 심각성을 더해가고 있는 차제에 지난해(1997) 12월 일본 교토에서 제3차 기후변화협약 조약국 회의가 개최되었으며, 회의 결과 일차적으로 선진국에서 온실 가스 배출 감축 목표를 설정하여 2008년부터 시행토록 합의하였다. 우리 나라는 이 회의에서 온실 가스 배출 감축 대상국에서는 제외되었지만 OECD에 가입한 국가로서 멀지 않아 감축 목표 이행 대상국에 들게 될 것으로 예측된다. 이와 관련하여 OECD/NEA는 지난 4월 $\ulcorner$원자력발전과 기후변화$\lrcorner$라는 보고서를 발표하였다. 이 보고서는 비교적 최근의 연구 자료를 인용하여 원자력이 온실 가스 배출 억제에 어떤 역할을 하는가를 연구한 내용으로서 우리 나라에서도 에너지 정책 입안 등에 도움이 될 것으로 판단된다.

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.

청정개발체제(CDM)란 '기후변화의 부정적 효과 완화'와 '개도국의 지속 가능한 발전 지원'이라는 기후변화협약의 양대 목표를 비용 효과적으로 이행하기 위해 교토의정서에 마련된 수단이다. CDM은 선진국인 부속서 I 국가와 이에 해당하지 않는 비(非)부속서(non-Annex) I 국가 즉 개도국이 배출감축을 위해 공동으로 노력하고 그 결과 창출된 온실가스 감축 분을 이 두 그룹 국가간에 배분되도록 한 제도다. 즉 선진국은 개도국에 자본과 기술을 투자하여 온실가스 저감사업을 벌이고 이 과정에서 발생한 온실가스 배출감축 분을 자국의 감축실적(credits)으로 인정받게 되고, 개도국은 이 과정에서 기술이전 및 재정지원의 혜택을 받을 수 있게 되어 있다. CDM은 따라서 세계 대다수의 국가가 직 간접으로 영향을 받지 않을 수 없을 것이며, 이로 인해 CDM의 구체적 실천 방안을 둘러싸고 각 국간의 이해 관계가 좀처럼 좁혀지기 어려운 상황이다. 이에 따라 지난해 부에노스 아이레스에서 개체되었던 COP-4에서는 CDM 체제를 비롯한 기후변화협약의 핵심 쟁점사항을 오는 2001년(또는 2002년)에 개체될 COP-6까지 일괄 타결키로 한 부에노스 아이레스 행동계획을 채택하는 데 그쳤다. CDM이 향후 어떤 형태로 결정되는 가에 따라 우리 나라가 받는 영향도 상당한 차이가 날 것이다. 따라서 CDM의 전개 방향을 면밀히 주시하고 이에 대한 대응책 마련이 절실히 요구되고 있다.

The national accounting matrix including environmental accounts(NAMEA) includes informations on environmental pressures in relation to economic activities as developed in the national accounts. In the NAMEA, conventional national accounts tables have been extended with accounts in physical units. This paper describes the background for work carried out on environmental accounts in Korea and explains how the NAMEA-air is developed. The Korea's NAMEA-air provided here serves several purposes; (1) a consistent and systemic feature of the interrelationship between the economy and the environment; (2) a basis for environmental economic analysis; and (3) the vital information for climate and air policy planning.

The purpose of this study is to establish a methodology for evaluating quantitative effects of transportation GHG (greenhouse gas) reduction-related policies that were implemented based on the reduction goals of transportation GHG and effective implementation plans. This study uses a modal utility function and demand estimation models as well as a GHG emission basic unit estimation model by each transportation mode based on actual traffic and emission data. The results showed that the effects of GHG reduction policies such as electric vary from region to region, and from vehicle to vehicle. It is also confirmed that an eco-drive promotion policy, one of the lowest budget policies, is expected to contribute to high reduction in GHG. In addition, not only automobile emission improvement policies but also the promotion policies of public transportation are expected to highly reduce GHG as confirmed quantitatively in this study. The results of this study are expected to be useful for national and local governments' evaluation of GHG reduction policies to cope with the post 2020.

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.
