Banking and borrowing under the ETS may affect the low carbon technology investment level. If the indirect implementation measures are allowed, firms can gradually adjust their carbon reduction costs between implementation periods based on their carbon reduction costs and emission price forecasts. This implies that banking and borrowing may reduce or increase the level of low carbon technology R&D investment. In an oligopoly market, the effects of the measures are quite different from the ones in a perfectly competitive market. This is because the indirect implementation measures can shift market competition in Cournot competition model. The effects of banking and borrowing on the carbon reduction R&D investments depend on emission reduction costs, marginal production costs, discount rate, initial free allocation, and the cost reduction effects of R&D investment.

The dominator tree presents the dominance frontier from directed graph to the tree. we present the effective algorithm for constructing the dominator tree from arbitrary directed graph. The reducible flow graph was reduced to dominator tree after dominator calculation. And the irreducible flow graph was constructed to dominator-join graph using join-edge information of information table. For reducing the dominator tree from dominator-join graph, we implement the effective sequency reducible algorithm and delay reducible algorithm. As a result of implementation, we can see that the delay reducible algorithm takes less execution time than the sequency reducible algorithm. Therefore, we can reduce the flow graph to dominator tree effectively.

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.

우리나라 전체 온실가스 배출량을 2020년까지 배출 전망치(BAU) 대비 30% 줄이기로 한 것에 맞춰 각 부문과 업종이 분담해야 할 감축 목표량이 정해 졌다. 수송 부문이 34.3%로 감축률이 가장 높고 다음은 건물 26.9%, 발전 26.7%, 공공 기타 25% 순이다. 관심을 끌었던 산업 부문 온실가스 배출량 감축률은 18.2%로 정해졌다. 폐기물은 12.3%이고, 농림어업은 상대적으로 부담이 덜하도록 5.2% 감축률을 배정받았다. 정부는 이같은 내용의 '부문별 업종별 연도별 국가 온실가스 감축목표'를 지난 7월 12일 국무회의에서 확정했다.

배출권 거래제의 가장 큰 장점은 주어진 감축목표를 최소의 비용으로 달성할 수 있다는 것이다. 따라서 감축목표가 명확하지 않을 경우 배출권 거래제는 정상적인 기능을 발휘하기 어렵다. 온실가스 감축목표의 경우 기후변화문제의 장기적 특성으로 인해 단기적 목표보다는 중장기적 목표의 설정이 중요하다. 결국 국가 차원의 중장기 온실가스 감축목표의 설정이 배출권 거래제의 선행 요건이 된다. 현재 우리나라는 2020년에 대한 국가 목표만 있는 상황인데, 배출권 시장의 원활한 운영을 위해서는 2030년은 물론 2050년에 대한 국가 온실가스 감축목표의 설정이 필요하다. 배출권 시장은 단기적인 목표 뿐만 아니라 중장기적인 목표가 감축여건과 동시에 가격 형성에 영향을 줌으로써 비용효과적 자원배분을 촉진할 수 있다.

중소기업중앙회 등 33개 경제단체 및 38개 발전 에너지기업은 지난 6월 16일 정부가 최근 발표한 2030년 온실가스 감축 목표에 대한 공동의견서를 발표했습니다. 경제계는 발표문에서 "정부가 본실가스 감축 목표를 과도하게 실정해 우리 기업의 경쟁력이 약해지고 산업공동화 현상을 초래할 수 있다"며 "2030년 온실가스 감축 목표치를 재조정해야 한다"고 주장했습니다. 7 8월 골판지포장물류지에서는 최근 정부가 제시한 2030년 온실가스 감축 목표안과 감축이유에 대해 자세히 살펴보도록 하겠습니다.

2008년부터 유럽연합국가, 일본, 러시아 등은 2012년 연간온실가스 배출량을 평균적으로 1990년의 배출량보다 약5%정도 낮은 수준으로 제한하여야 한다. 이러한 온실가스 배출량 감축을 위해서 선진국들은 국내적으로는 에너지효율향상, 신재생에너지 보급확대 등의 정책을 시행하고 있으며, 이를 보다 낮은 비용으로 감축하기 위하여 국내 또는 역내 온실 가스배출권 거래제도를 도입하여 시행하고 있다. 이들 국가들은 국내정책만으로는 최소의 비용으로 온실가스 감축목표를 달성할 수 없다는 인식하에 동유럽국가, 그리고 중국 등 개발도상국들에 대한 온실가스 감축사업에 투자를 하여 온실가스 감축의 일부 또는 전부를 자국의 감축실적으로 인정받는 공동이행체제(joint implementation), 청정개발체제(clean development mechanism)사업을 전개하고 있다.

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 bottom-up approach has been conducted to estimate greenhouse gas (GHG) emission and to analyze the marginal abatement cost for the Korean horticulture energy sector. With the systematically derived activity and energy balance data, the BAUs have been estimated, along with the marginal abatement cost over the period 2010 through 2030. The result from the marginal abatement cost analysis may provide general guidelines and procedures for the establishment of GHG abatement polices.

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.
