The fishing industry has a negative effect on the environment due to greenhouse gas (GHG) emissions with the high use of fossil fuels, the destruction of underwater ecosystems by bottom trawls, reduction in resources by fishing, and altered ecosystem diversity. GHG emissions from fisheries were discussed at the Canc$\acute{u}$n meeting in Mexico in 1992 and are part of the Kyoto protocol in 2005. However, few studies have investigated the GHG emissions from Korean fisheries. To find a way to reduce GHG emissions from fisheries, quantitative analysis of GHG emissions from the Korean fishery industry is needed. Therefore, this study investigated the GHG emissions from the Korean Danish seine fishery using the life cycle assessment (LCA) method. The system boundary and input parameters for each process level are defined for the LCA analysis. The fuel-use coefficient of the fishery is also calculated. The GHG emissions from the representative fish caught by the Danish seine fishery are considered and the GHG emissions for the edible weight of fishes are calculated, considering consumption in different areas and different slaughtering processes. The results will help to understand the GHG emissions from Korean fisheries.

Increase of the greenhouse gases emissions during last century has led remarkable changes in our environment and climate system. Continuous monitoring of atmospheric constituents over the world is positively necessary to understand these changes around us. The concentrations of greenhouse gases ($CO_2,\;CH_4,\;N_2O,\;CFCs$) have been continuously measured at Global Climate Change Monitoring station in Gosan, Jeju since January, 2002. In this study, the variation characteristics of greenhouse gases as well as their annual, seasonal and diurnal trend using the data from January, 2002 to December, 2005 were analyzed. The raw data which was used in the analysis were validated with the methods recommended by WDCGG (World Data Center for Greenhouse Gases). The concentration of $CO_2$ was increasing continuously by 2.1 ppm/year, while $CH_4$ did not show any increasing or decreasing trend clearly for 4 years. The concentration of $N_2O$ was slightly increasing and CFCs were decreasing except CFC-12 which has longer lifetime compared with other CFCs. The variations of the greenhouse gases at Gosan were shown to be consistent with the global trend. But the concentration level of $CO_2$ in Korea was more or less higher than abroad.

The field of agriculture, forestry, and other land-use (AFOLU) is concerned with greenhouse emissions of agriculture (crop and livestock), as is the field of land-use, land-use change, and forestry (LULUCF). The 1996 IPCC guideline and the 2006 IPCC guideline are used in combination for calculation of greenhouse gas emission from the agricultural sector, and the 2003 IPCC guideline is used for that from the land-use sector. In this research, we analyzed GHG emissions of the cropland sector in AFOLU based on the 2006 IPCC guideline. The results showed that GHG emissions of 1990 was $-504Gg{\cdot}CO_2-eq$, while that of the last year was $2,871Gg{\cdot}CO_2-eq$. Compared with the 2003 methodology, total emissions according to the 2006 IPCC was lower except in 1997 and 2003. This trend is due to difference of analyzed emission sources, lower default values, and global warming potential by the 2006 IPCC. The results are estimated using limited data at the Tier 1 level and the first issue to be solved is the activity data from the land-use change matrix. Although this result should be improved, it can be used as the basis for calculating GHG emissions of the AFOLU sector.

온실가스로 인한 세계 기후 변화가 심각해지고 있다. 이를 방지하기 위해 세계 각국에서는 온실가스 배출 규제를 하고 있다. 국내는 온실가스 배출량을 2030년까지 BAU(Business As Usual) 대비 37% 감축하기로 하였다. 국내 온실가스 배출 비중 중 교통부문이 18.58%에 해당하는 데 그중 도로가 93.75%에 해당하는 대부분의 수치를 기록했다. 대중교통 또한 온실가스 감축 대상에 포함되는데 본 연구는 도로 교통 중 비용이 상대적으로 적게 들면서 온실가스 감량을 할 수 있는 버스 대중교통의 온실가스 감축을 위해 진행했다. 본 연구는 애니 로직을 활용하여 온실가스 시뮬레이션 모델을 구현해 버스의 배차 간격을 조정하여 승객의 대기시간 대비 최적의 온실가스 배출량을 예측하는 시뮬레이션을 진행했다. 향후 더욱 정밀한 모델을 구현한다면 버스 온실가스 감축에 활용될 것으로 기대한다.

The present study attempts to understand the emission pattern of greenhouse gases in people's daily life through the estimation and analysis of the amount and characteristics of the greenhouse gases. Based on the survey of 1,000 people throughout the nation, monthly emission of greenhouse gases per-capita was estimated from their use of fuels, electricity, water, and personal and public transportation means in addition to their waste generation. In the case of personal car drivers, greenhouse gas emission was the greatest from their cars, followed by the emission from electricity, fuels, and public transportation. Emission from water consumption and waste generation was relatively low. Fuel consumption varied depending on the number of household members, their housing type, and the size of their living spaces. Results showed that single-person households emitted the largest amount of per-capita greenhouse gas while greenhouse gas emission from electricity was inversely proportional to the number of persons in a given household.

최근 온실가스 감축을 위한 세계 각국의 노력이 다각도로 진행되고 있으며, 국제적인 협력 또한 시급히 요구되고 있다. 이러한 노력의 일환으로 해운 업계에서는 항내에서 유발되는 선박 기인 온실가스 배출량 중 탄소에 대한 배출량 감축과 선박운항 비용 절감을 위한 친환경 항만 체계 구축 방안이 활발히 논의되고 있다. 이 논문에서는 탄소 배출량 감축 및 친환경 항만 체계 구축의 기초 연구로 정박 중인 선박에 자체 생산 전력을 공급하는 대신 육상전력을 공급하는 방안을 모색하였다. 이를 위하여 실제 운항중인 목포해양대학교의 실습선 새누리호를 대상으로 정박 중인 선박이 육상전력을 사용함으로써 얻을 수 있는 환경적 비용적 효과에 관해 고찰하였다. 연구 결과 육상전력을 사용한 경우에 $CO_2$ 배출량은 약 32.5%가 감소되었고, 운항비용은 약 33%가 절감된 것으로 나타났다.

The aim of this study is to calculate process emission of GHGs(greenhouse gases) in nonferrous-metal industry, such as Zn, Pb, Cu and Ni. In addition, variation and emission of GHGs generated from these company were defined. And then, GHGs algorithm and calculation formular which were considered as production process in each part of nonferrous-metal industry were developed to develop calculation program of GHGs emission. These algorithm and calculation formular would present fundamental direction about other nonferrous-metal industry in the future.

한국 및 여타 국가들의 온실가스 배출 관련 정책들은 기본적으로 배출 전망치를 바탕으로 수립되는바, 노동생산성이 높은 증가세를 보이는 부문에서 낮은 증가세를 보이는 부문으로 진행되는 구조적 변화-산업별 노동생산성 증가, 산업 전반의 배출 저감, 인구 증가를 고려한-의 예상경로가 핵심 요소가 된다. 따라서 구조적 변화의 원인을 모델화하는 작업은 배출량의 정확한 예측을 위해서 중요하다. 본 보고서는 한국경제 데이터를 활용하여 구조적 변화와 녹색성장 모델을 수립 및 평가함으로써 한국과 국제사회의 온실가스 담론을 위한 정책 함의성을 도출한다.

The aim of this study is investigated greenhouse gas emissions of glass industry, and when calculates greenhouse gas emission, using formula(Tier 3) advising in IPCC(Intergovernmental Panel on Climate Change) and using self designed formula(Tier 3+) authors of this study. Studied to propose calculation formula that can compare these two calculation results and apply to domestic. Formula of Tier 3 calculated to theoretical composition of carbonate material, And Formula of Tier 3+ calculated on the basis of chemical substance formation table that get from glass manufacture company(The S company). As a result, Dolomite, Soda ash, Limestone, Industrial Barium carbonate is calculated value of Tier 3+ lower than value of Tier 3, And Industrial Potassium carbonate, Industrial Strontium carbonate was calculated value of Tier 3 lower than value of Tier 3. This study finding, formula of Tier 3+ has higher confidence than formula of Tier 3 when consider revision about purity of injection raw material. And hereafter, When calculate greenhouse gas emissions about nonmetallic mineral industry, use of Tier 3+ is considered that should be encouraged.
