  • The voluntary mid-term greenhouse gas(GHG) emission reduction targets for 2020 among major developed and developing countries were evaluated by using the global computable general equilibrium(CGE) model. The GHG emissions of developed countries were estimated to be reduced by 14.0% from 1990 level, which implies that the GHG reduction targets of developed countries should be strengthened to reach agreement in future post-Kyoto negotiations. The voluntary participation of developing countries for GHG emissions reduction contributed to global GHG emissions reduction by 15.9% from 1990 levels, which were led by the participation of China and India. These outcomes imply that the reinforcement of GHG emission reduction targets in developed countries and the wider participation of developing countries will be necessary for the environmental effectiveness of the post-Kyoto regime. Emissions reduction based on voluntary targets will decrease the global real GDP by 1.18%.

  • Traditionally, UNCLOS stipulates that States have the obligation and responsibility to protect and preserve the marine environment and exercise their rights in Principle of Non-Discrimination with respect to foreign ships visiting to port states. UNFCCC and Kyoto protocol established Common but Differentiated Responsibility as the basis which is established on the historic responsibility. The principle in which IMO is presently developing the regulations of Green House Gas emitted from ships is contradict with the principle of UNFCCC regime. In this paper, the development and the principle of UNFCCC and Kyoto protocol is surveyed and it provides the tendency of the IMO activities regarding GHG emission from ships. Also, through consideration of the problems and restrictions drawn from comparison between two principles, the conclusion suggests the fundamental theory and implementation means in order to carry out the purpose of IMO regulations in accordance with the principles of UNCLOS and IMO Convention.

  • As the seriousness of the global environment pollution is gaining our attention recently, researches on application of greenhouse gas emission of ship are being carried globally. However domestic study on greenhouse gas emission from ship was not carried out in various fields. In this study, quantitative data which was presented by greenhouse gas emission of training ship HANBADA and greenhouse gas emission was calculated by Tier 1 method based on total fuel consumption and amount of shore power. Actual voyage data for 1year in 2012 was used to analysis the greenhouse gas emission. This study showed how many weight of gases were exhausted per 1 gross tonnage and per 1trainee in the training ship. There is a need of further research to reduce pollutant and to respond to international environment regulation consistently.

  • In accordance with the enactment of 'the Paris Agreement' in 2015 and 'the Framework Act on Carbon Neutrality and Green Growth for Response to the Climate Crisis' in 2021, each local government has set appropriate reduction target of greenhouse gas to achieve the nationally determined contribution (NDC, the reduction target of 40% compared to 2018) of greenhouse gas (GHG) emissions in 2030. In this study, the current distribution of GHG emissions was analyzed in a time series centered on the Chungbuk region for the period from 1990 to 2018, with the aim of reducing GHG emissions in Chungbuk by 2030 based on the 2030 NDC and scenario. In addition, the prospected reduction by 2030 was estimated considering the projected emissions according to Busines As Usual in order to achieve the target reduction of GHG emissions. Our results showed that GHG emissions in Chungbuk and Korea have been increasing since 1990 owing to population and economic growth. GHG emissions in 2018 in Chungbuk were very low (3.9 %) relative to the national value. Moreover, emissions from fuel combustion, such as cement and lime production, manufacturing and construction industries, and transportation industries, were the main sources. Furthermore, the 2030 target of GHG emission reduction in Chungbuk was set at 40.2% relative to the 2018 value, in accordance with the 2030 NDC and 2050 carbon-zero national scenario. Therefore, when projected emissions were considered, the prospected reduction to achieve the target reduction of GHG emissions was estimated to be 46.8% relative to 2018. The above results highlight the importance of meeting the prospected reduction of GHG emissions through reduction means in each sector to achieve the national and local GHG reduction target. In addition, to achieve the 2030 NDC and 2050 carbon zero, the country and each local government, including Chungbuk, need to estimate projected emissions by year, determine reduction targets and prospect reductions every year, and prepare specific means to reduce GHG emissions.

  • This study analyzes correlation between methane gas production and injection of food waste water to motivate to expand renewable energy as a way of GHG (Green House Gas) mitigation to achieve the national GHG target proposed for the climate agreement in Paris last year. Pretreatment of food waste water was processed with pH 6 at $35^{\circ}C$ and used the fixed-bed upflow type reactor with the porous media. As a result of operation of pilot-scaled bioreactor with food waste water, the methane gas production was 6 times higher than the methane gas production of control group with rain water. The average production of methane was $56{\ell}/day/m^3$ which is possible to produce $20m^3$ of methane in $1m^3$ of landfill. As a way of energy source, when it is applied to the landfill over $250,000m^3$, it is also able to achieve financial feasibility along with GHG reduction effect. GHG reductions of $250,000m^3$ scale landfill were assessed by registered CDM project and the annual amount of reductions was 40,000~50,000 $tCO_2e$.

  • 온실가스배출권거래법이 2015년 1월부터 시행될 예정이다. 온실가스 배출권 거래제는 현재 시행중인 배출가스 목표관리제에서 한발 더 나아가 정부가 그동안 추진해 온 녹색성장 정책에 따른 국가 온실가스 감축 목표 달성을 적극적으로 이루기 위한 제도라 할 수 있다. 또한 배출권 거래제를 다른 개도국보다 빨리 도입함으로써 향후 기후변화협약 논의 과정에서 선진국과 개도국간의 갈등을 조정하는 역할을 수행하면서 국제적 리더십을 확보하고자 하는 정책적 의도도 담겨 있는 것으로 보인다. 여기서는 한국자동차산업연구소 신은주 연구위원의 '배출권 거래제 입법화 의미와 영향'보고서를 통해 배출권 거래제 추진의 의미와 영향, 외국의 배출권 거래제 현황 및 시사점에 대해 살펴본다.

  • 온실가스의 배출자료는 기후변화협약 참여협상 및 저감대책 수립에 없어서는 안될 중요한 기초자료이다. 그러나 국내에서는 현재 에너지와 농업 분야를 제외하고는 온실가스의 배출원 및 배출량 조사가 미미한 실정이다. 이번 연구에서는 기후변화와 관련된 온실효과에 커다란 기여를 하고 있는 메탄($CH_4$)의 매립지 표면으로부터의 국내 배출량을 조사하고자 한다. $CO_2$, $CH_4$, $N_{2}O$, $O_3$, CFC 등의 주요 온실가스들은 여러 경로를 통해서 대기로 배출되고 있으며, 온실가스의 배출기여도를 보면 도시쓰레기의 매립이 전체 배출량에 약 3%정도 기여하는 것으로 보고되었다.
