As a part of efforts to reduce the global emissions of greenhouse gases, the Kyoto Protocol was signed by major developed countries ("Annex I" countries). According to the Kyoto protocol, the Emission Trading Scheme that derives a trading market of the $CO_2$ emission rights is appeared. It causes that business institutions give lots of efforts to reduce $CO_2$ by using new environmentally sound technologies or increasing efficiency in production. On the while there have been several studies trying to develop a methodology to measure the effect of $CO_2$ reduction and its monetary value. In this research we suggest ECRE (Evaluation of $CO_2$ Reduction in E-transformation) model which can measure the $CO_2$ reduction effect through the introduction of G2B system. ECRC model was developed based on the IPCC methodology. ECRC model measures the two major effects of the $CO_2$ reduction which are '$CO_2$ reduction effect from transportation' and '$CO_2$ reduction effect from the decrease of paper use'. In this paper, we calculate the economic effect of $CO_2$ reduction with the case of the G2B system in Korea. This research suggests a basic methodology to measure the $CO_2$ reduction performance for the e-transformed institution.

Carbon dioxide is considered a major greenhouse gas that contributes to global wanning. $CO_2$ is a major component of the exhaust in the combustion of any hydrocarbon fuel. The regulation for $CO_2$ emission from vehicles has become much more stringent in recent years. These more stringent regulations require vehicle manufacturers to develop alternative fuels that reduce exhaust emissions. This paper evaluated the correlation of $CO_2$ emission and fuel economy in the Gasoline, Diesel, and LPG vehicles according to FTP-75 and NEDC(ECE15+EUDC) driving mode. From this study, we discovered that the decrease rate of $CO_2$ emission is higher for fuels of lower carbon concentration. When the relationship between $CO_2$ emission and fuel consumption rate according to used fuels is expressed as a function, one can find out that they have a high correlation. LPG vehicles produce less $CO_2$ emission than gasoline and diesel vehicles.

The purpose of this paper is to measure economy and environment efficiencies under fossil fuel and environment regulation by countries for 2000-2009. Distinguishing 83 countries with three groups of OECD, upper-middle, and low countries, we compare four models such as environment oriented, economy-oriented, environment-economy oriented, and two-stage types, which include a desirable output, GDP and an undesirable output, pollutant together in the production possibility set. OECD countries relatively showed high economy efficiency and low environment efficiency, whereas Non-OECD countries showed high environment efficiency and low economy efficiency. OECD countries reported a higher possibility to reduce fossil fuel and $CO_2$ emission.

Lean premixed combustion was successful in meeting current NOx emission regulations. However, these often leads to combustion instability. This phenomena results from the feedback relationship between heat release perturbations and acoustic pressure oscillations in the combustor. Researches on the combustion instability in an annular combustor have recently received great attention due to the enhanced NOx requirement in aero-engines. In this study, the thermoacoustic network model has been developed in order to calculate the acoustics for longitudinal as well as circumferential modes in the annular combustor. The combustion model in the network model is calculated by flame transfer function(FTF). Numerical and analytical results are compared to an measurement data.

The emission trading system implemented in Korea is a system in which the government allocates or sells emission rights by setting the emission allowable amount to economic players subject to the emission trading system, allowing companies to freely trade shortfall or extra money through the emission trading market. Korea also had implemented its first emission trading system scheme period of time from 2015 to 2017. As a result of the first planning period in which total of seven Korean airlines were targeted, the emission amount was about 5.51 million KAU, while the quota amount was only about 4.85 million KAU, about 116% of the actual quota was emitted and Domestic airlines have incurred additional costs of about 10.7 billion won. Due to ICAO's implementation of CORSIA, the airlines are expected to have to shoulder additional costs because purchasing exceed quota will be increased in order to offset excess emissions not only on domestic but also on international routes. Thus, this paper had analyzed the characteristics of the carbon trading system of air transport industry and suggested a mix of regulatory policies as an improvement method.

유럽 국가들이 해양환경 오염의 심각성을 인식하여 1972년 최초로 해양투기를 규제하기 위한 지역협정인 오슬로 협약(Oslo Dumping Convention)을 체결하게 되었다. 이를 모체로 하여 런던에서 범세계적인 규제의 필요성이 제기되어 국제협약인 런던협약(London Convention)이 1972년에 체결되었다. 그 후 1990년대에 들어 런던협약 당사국들은 협약을 보다 근본적으로 개정할 필요가 있다는데 의견을 같이 하게 되었다. 1993년 제1차 개정그룹회의 이후 3년간의 작업 끝에 1996년 11월 7일 IMO 본부에서 열린 특별회의에서 1996년 의정서('96 의정서)가 채택됨으로써 협약의 전면적인 개정작업이 완성되었다. 우리나라는 2009년 1월 22일 가입하였으며 2009년 2월 21일에 발효되었다. 이에 따라서 우리나라는 폐기물 해양배출량을 지속적으로 감축하고자 노력 중이다. 본 논문에서는 폐기물 해양배출의 감축과 관리를 보다 효율적으로 하기 위하여 필요한 기술개발과 시스템 구축, 그리고 정부 및 지방자체단체의 정책수립과 법률개정을 위한 자료를 제공하고자 한다.

In this paper, a portal system compatible with MRV regulation was designed to monitoring, reporting and verifying $CO_2$ emission and fuel consumption data from an international ship. A portal system supports monitoring and reporting task of international shipping companies and calculates national greenhouse gas inventory. EU MRV law, MRV discussions of IMO, responses of international shipping companies to ship energy efficiency and greenhouse gas regulation, and greenhouse gas statistics on international shipping were analyzed to drive portal system requirements. For ship energy efficiency and $CO_2$ emitted monitoring, a data collection module was designed based on on-board equipment, energy efficiency measuring device and navigation report. Data transfer module with easy management and minimized usage to transfer ship data to shore was designed. A portal system was designed to convert the collected data into the standard reporting format, perform monitoring, statical analysis, verification and auto report generation, and support national greenhouse gas inventory.

This paper described the estimation methods of CO2 emission of vehicles. The important of energy and environment has emerged in the world, and the field of vehicle's development as well. CO2 was particularly the object of emission-regulation that caused of global warming. There are performance comparison methods by driving mileage, International Panel on Climate Change (IPCC) and chemical equation for the combustion of Octane. We took the measurement by getting data through OBD-II port from vehicle covered 5 km on road. We got the diagnosis information, specific mileage and fuel consumption in this experiment. We are able to expect similar CO2 emission by the methods in the normal speed driving. Also, we can make more realistic approach of CO2 emission by the method of estimation by IPCC and chemical equation for the combustion of Octane in rapid acceleration driving.

Integrated Pollution Prevention and Control(IPPC) has become an idealistic environmental prevention concept in developed countries and corresponds with principles of Industrial Ecology. The concept of emissions regulatory integration is a key factor for an integrated environmental management system. While most EU member countries have a cross-media regulatory system, Korea has a media-specific regulatory system which was found to have significant environmental management problems. The purpose of this study is to integrate the emissions regulatory system by resolving difficulties through procedural, organizational, and substantive analysis of integration. To this end, the following research was performed: The first task was to determine the target of the integrated emissions regulatory system. In connection with this, the "IPPC directive" of the EU and the "PPCA 2000" schedule 1 of the UK, as well as environmental laws in Korea were compared and analyzed. The second was to design a regulatory system model. This model was divided into three groups after considerations were made regarding the time it would take for the pre-application,application, and permission stages. Lastly, on the basis of this research, a revised bill for an integrated emissions regulatory system was suggested. Nevertheless, substantive analysis of integration focused on BAT requires supplementation in order to make the integrated emissions regulation system operate normally as an environmental management policy and regulation method. To this end, the specific characteristics of Korean society, culture, and law should be actively considered.
