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.

The Korean government recently announced greenhouse gases (GHG) emissions reduction target as 30% of 2020 business as usual (BAU) emission projection. As carbon emissions trading is widely used to achieve reductions in the emissions of pollutants, this study deals with the sectoral allocation of initial carbon emission permits in Korea. This research tests the effectiveness of a variety of allocation rules based on the bankruptcy problem in cooperative game theory and hybrid input-output tables which combines environmental statistics with input-output tables. The impact of initial emission permits allocation on economic growth is also analyzed through green growth accounting. According to the analysis result, annual GDP growth rate of Korea is expected to be 4.03%, 4.23%, and 3.67% under Proportional, Constrained Equal Awards, and Constrained Equal Losses rules, respectively. These rates are approximately from 0.69% points to 0.13% points lower than the growth rate of 4.36% without compulsory $CO_2$ reduction. Thus, CEA rule is the most favorable in terms of GDP growth. This study confirms the importance of industry level study on the carbon reduction plan and initial carbon emission permits should reflect the characteristic of each industry.

Purpose: The purpose of this study is to quantitatively present the carbon dioxide(CO₂) emission change according to the application of autonomous driving technology at the network level for waste vehicles in the metropolitan area. Method: The target year was set to 2030, and the analysis method estimated the carbon dioxide (CO₂) emissions for each road link through user equilibrium assignment when unapplied scenario. The application scenario performed traffic assignment using route data on the premise that the group was running in accordance with the application of autonomous driving technology to waste vehicles. In addition, the other means estimated the carbon dioxide emissions through user balance allocation by reflecting the results of the waste vehicle allocation. Result: As a result of the analysis, carbon dioxide(CO₂) emissions were found to be reduced by about 56.9ton/day from the national network level, and the Seoul metropolitan area was analyzed to be reduced by about 54.7ton/day. Conclusion: This study quantitatively presented environmental impacts among various social effects that autonomous driving technology will bring, and in the future, development of various analytical methodologies and related studies should be continuously conducted.

Enforcement Decree of the Framework Act on Low Carbon, Green Growth for achieving the country's GHG emission reduction goal of 30% was in effect. The remarkable content of the Act is the managements of targets for GHG reduction. So, the entities that have reduced voluntarily have much interest in the recognition of 'early action'. The recognition of early action is necessary to induce the fair competence of business entities and promote the voluntary GHG reduction. The definite and concrete guidance should be prepared. The important principles for this are the environmental integrity and the additionality. Based on this, the early action activities must be restricted to the voluntary, real, permanent, quantifiable, verifiable reduction. In the early action recognition, its credit should be allocated additionally set aside from the GHG target allocation in the national total allowance. Through this, the reward for the early reduction should be realized on market mechanism. The effective period to award the early action should be addressed. This can be the period after the enactment of framework on GHG reduction in effect and before the beginning year of GHG target control. It should be set with flexibility through the collection and consultation of the sector's opinions. The appropriate allowance reserve of early action was estimated as approximately 1~1.5% by using the data from the 'Pilot GHG Emission Trading Program' operated by Ministry of Environment. Also, the concrete and detail guidance to construct the necessary infra which is used to register the related information of early action activities should be prepared.
