Korean government established the Nationally Determined Contribution (NDC) in 2015. After revising in 2019, the government updated an enhanced target at the end of last year. When the NDC is addressed, the emission targets of each sector, such as power generation, industry, and buildings, are also set. This paper analyzes the emission target of each sector by applying a claims problem or bankruptcy problem developed from cooperative game theory. The five allocation rules from a claims problem are introduced and the properties of each rule are considered axiomatically. This study applies the five rules on allocating carbon emission by sector under the NDC target and compares the results with the announced government target. For the power generation sector, the government target is set lower than the emissions allocated by the five rules. On the other hand, the government target for the industry sector is higher than the results of the five rules. In other sectors, the government's targets are similar to the results of the rule that allocates emissions in proportion to each claim.

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.

Reducing emissions across all sectors requires a well-designed policies tailored to fit specific national circumstances. And every climate policymaker would like to have an accurate method of assessing the quantitative impacts of future policies to address GHG-related problems. Estimates of future changes in a nation's GHG emissions, the expected environmental impacts of future energy sector developments, and the potential costs and benefits of different climate technology and mitigation policy options are desirable inputs to policy making. Various mitigation analysis and modeling approaches helped to fill the needs for these kinds of information, and as such has been an important part of national mitigation policy making in many countries for most of two decades. This paper provides a overview of GHG mitigation policies and mitigation analysis, and sectoral mitigation circumstances and potentials.

It is necessary to determine the current and future energy consumption by farm households for the rational specification of energy related policy in the Korean agricultural sector. Especially, It is important to identify the consumption by source of energy and by the crops. On the other hand, the world has tried to reduce the production of greenhouse gases and, in line with this, the Korean government established related legislations to contribute to this reduction (30% reduction in emissionsby 2020). The reduction target of the agricultural sector is specified as 5.2% of the national total. This study focuses on sampling design to determine the energy consumption and emission of greenhouse gases, and suggests several alternatives to improve the confidence level and to make a dent survey and estimation errors. The population for the energy consumption survey of the agricultural sector was derived from agricultural census data. In the case of commodities with high skewness, we cut the sample range to within the statistical significant range. The number of samples in each class is specified using the Neyman allocation method and 95% significance level. The estimation results are compared with the population to verify the statistical significance and several management methods of sampling errors are suggested.

The purpose of this paper is to analyze the sector-specific greenhouse gas reduction implementation strategies priority using the multi-criteria analysis methods (AHP and Feedback ANP). Our analysis demonstrates that the highest priority among the evaluation criteria is given to the feasibility compared to the efficiency and the effectiveness in most of the sectors. In the public and the building sectors, it has been found that the governmental driving force is absolutely crucial in technological dissemination and diffusion. The results and the main findings are as follows. Firstly, the priority of the policy evaluation criteria has been changed by analysis methods. Secondly, the total weight and the priority of each sector's alternatives also have been changed. Finally, the priority of the alternatives for criteria has been changed by the analysis methods.

Since the release of mid-term domestic GHG goals until 2020, in 2009, some various GHG reduction policies have been proposed. In case of the transportation sector for the mid-term domestic GHG goals, it targets to reduce about 30% regarding the doemstic economic growth until 2020. A major reduction method in passenger cars considers an electric car. In this study we analyze some various scenarios to compare between internal combustion engine car and electric car using break-even analysis. Through the analysis we suggest a subsidy policy for electric car.

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.

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.

To meet sectoral emission target by 2020 and prepare for the emission trading scheme from 2015, decomposition analysis of energy consumption and GHG emission is required by 18 subsectors in industry sector where emission targets are established. Log Mean Divisia Index decomposition method was used to analyze factors' effects on energy and emission in the industry sector and by 18 subsectors from 2004 to 2011. Industrial energy consumption was increased due to the production effect and energy intensity effect. However structure effect contributes to the decrease of energy consumption. In terms of emissions (including indirect emission due to electricity consumption) in the industry sector, only structure effect contributed to the emission reduction. Factors' effects by subsectors were different. Cement industry, which is included at Nonmetal shows different results from those of Nonmetal industry and machinery industry, which is a subsector of Fabricated Metal, was also similar. In this regard, we should not apply the policy implications from decomposition analysis of aggregated industry such as Nonmetal or Fabricated Metal to its subsectors uniformly and develop a differentiated policy for each subsector industry.
