Kyoto Protocol against global warming came into effect in Feb 2005. Korea is expected to be put under obligation to decrease the $CO_2$ emission from 2013. Because the electric power plants burning fossil fuel occupy 25% of national $CO_2$ emission, calculating the amount is very important. This paper presents ; - a brief procedure of performance test of D thermal power plant - calculation and comparison of $CO_2$ emission of D power plant w.r.t the generator output for LNG and residual oil using the a, b, c coefficients obtained by the performance test - and a brief description on currently used chemical method for calculation of $CO_2$ emission

Our fossil fuels will be exhausted and replaced with renewable energies over tile next few decades. And rapidly increasing consumption of primary makes every country recognize the potential significance of climate change and necessity of greenhouse gas reduction. A critical part of the solution is to ratify the Kyoto Protocol and the UNFCC, and to develop and utilize the wind energy. One of the renewable energies, wind energy is increasing competitive in liberalised energy markets and shows annual growth rate of $20\~30\% in past five years. Thus, the purpose of this paper is to describe the necessity and characteristics of wind energy industries, to compare the international development policies of wind energy industries, and to suggest and discuss the alternative development policies of wind energies in Korea

Recently, the global warming phenomenon has been taken notice of. The global warming phenomenon has given enormous bad impact to social economic fields as well as ecological areas by rising sea levels and weather calamities. To cope with the phenomenon most developed countries adopted the Kyoto Protocol to reduce greenhouse gas emissions. To achieve the target of the Kyoto Protocol, the developed countries are operating organization-run green quality assurance and labelling systems with their standardized methods to evaluate the environmental and greenhouse gas impact for ICT products and services. This paper introduces several countries standards which can be applied to evaluate the reduction effect of greenhouse gas emission and green ICT quality assurance which also can be applicable for recycling and managing of ICT products. This paper is expected to be used as a policy data for ICT related government bodies and industry areas.

Environmental problems, such as the depletion of natural resources, global warming, and the destruction of ecological systems, are among the most serious problems facing the planet. Since the early 1990's, many OECD countries have undertaken green tax reforms by introducing new environmental taxes to protect the environment. Environmental taxes have been used as an instrument of environmental policy more than direct regulation because economic instruments have a comparative advantage over direct regulation in terms of cost effectiveness and pollution abatement incentives. However, one important reason why green tax reforms have not progressed is due to fears regarding the negative effect of environmental taxes on international competitiveness in the industry and trade sectors. The main purpose of this paper is to analyze the effects of environmental taxes on industry and trade by using a theoretical model to compare the effects of environmental taxes on pollution-intensive and energy-saving industries.

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.

Sulfur hexafluoride ($SF_6$), man-made compound, has been paid attention as a potent greenhouse gas. After Kyoto Pototcol on Climate Change in 1997, nations established the policy aimed at minimizing release of $SF_6$ to atmosphere. We have developed and operated an automatic analytical system for monitoring atmospheric $SF_6$ using gas chromatography with electron capture detector (GC-ECD) and packed separate-column. Here, we report and discuss 4-month record of atmospheric $SF_6$ concentrations monitored at Seoul National University (SNU) pilot station near the Kwanak Mountain, Seoul. Most of observed $SF_6$ concentrations were excessively high compared with Northern Hemisphere (NH) background trend obtained from National Oceanic and Atmospheric Administration (NOAA) Earth System Research Laboratory (ESRL) monitoring stations. And the observed $SF_6$ showed extremely wide variability ranging from 4.6 pptv to $1.1{\times}10^3$ pptv, which may be affected by local sources placed nearby. Simultaneous wind data with $SF_6$ measurements show that relatively high values of $SF_6$ correspond to weak wind as well as southerly. There are many engineering installations to the south of the station. The regional value of the atmospheric $SF_6$ estimated from the data selection by wind conditions is about 6.8 pptv. This value, which is similar to concentrations of urban areas, is higher than NH background concentration.

The dosage of intra-operative BNCT using near-threshold $^{7}$ Li(p,n)$^{7}$ Be direct neutrons was evaluated with the calculation method validated with the phantom experiment. The production of both neutrons by near-threshold $^{7}$ Li(p,n)$^{7}$ Be and gamma rays by $^{7}$ Li(p,p'gamma)$^{7}$ Li in a Li target was calculated using Lee's method and their transport in the phantom was calculated with MCNP-4B. As a result, the region satisfying the requirements of the protocol in intra-operative BNCT for brain tumors in Japan was acknowledged to be comparable to present BNCT, for the proton energy of 1.900 MeV for example. A boron-dose enhancer (BDE) introduced in this study to increase $^{10}$ (n,$\alpha$)$^{7}$ Li dose in a living body was effective. The void used to increase doses in deep regions was also valid with the BDE. It was found that intra-operative BNCT using near-threshold $^{7}$ Li(p,n)$^{7}$ Be direct neutrons is feasible.

In 1997, 180 countries signed the Kyoto Protocol in Kyoto, Japan. The Kyoto Protocol came into force in February 2005. The agreement calls for industrialized nations to cut greenhouse gas emissions by 5 percent from 1990 levels by 2008 to 2012. One of those polices is a modal shift that change from road freight to sea, inland waterway and railroad transportation that is eco-friendly. The increase of road freight brings road congestion, accidents, logistic costs, air pollution and greenhouse gases. Railroads are superior than the other modes of transportation in mass transportability, high speed, timeliness, safety and environmental-friendliness, but the railway industry has been pushed behind in competition. Korean railroads were used by passengers and freight transport popularly until the middle of 20th century, however, by the sudden change of logistics environments, a shaving time efficiency being most important, railroad logistic lost its competitive power against the transportation by truck. From the research which sees consequently investigated a various policy, a system and a law about Chinese logistics industry and present condition of the Chinese goods enterprise and instance analysis of the large Chinese corporation that branch out to undeveloped markets led and a Chinese logistics industry and problem point escape hereafter the heightening of competitiveness plan which is rational under prsenting boil.

The new paradigm called 'Low Carbon Green Growth' involved in reducing greenhouse gas is on the rise as a critical issue worldwide. The essential of Kyoto protocol issued in 1997 is to achieve the sustainable economic growth environments by converting existing production system to eco-friendly one. The protocol imposes the liability to reduce greenhouse gas to the countries joined to it. The paradigm is directly involved in the energy consumption and environmental pollution caused by construction activities. Value Engineering which are mainly applied in the design phase in practice is a measure to improve the value of a constructed facility by analyzing and/or appraising the functions and costs of it. However, an appropriate method which assesses eco-friendliness of constructed facility has not been propose by researchers. This paper proposes a method which assesses the performance involved in eco-friendliness of constructed facility using Value Engineering (VE) in the design phase. The method estimates the environmental cost relative to the amounts of energy consumption and environmental pollution occurred over the entire project life cycle. The database called "Life Cycle Inventory DB", which stores information about the amounts of environmental pollution, is used. The algorithm which retrieves the amounts of environmental pollutions from the DB and converts them into environmental costs is developed. The algorithm is implemented into a system which quantifies the eco-friendliness of constructed facility in the design phase using VE.

After Kyoto Protocol was adopted for green gas reduction, each nations are stepping up efforts to reduce $CO_2$ of a typical green gas. Construction industry also is trying $CO_2$ reduction with the techniques of two types which are software and hardware techniques. The software technique are Passive Design considered green gas emission and the environment impact assessment by LCA. The hardware techniques are adjustment of equipment system and development of eco- friendly material. But, it is nonexistent that a study related to $CO_2$ emission considered detail process in construction industry. This study analyzed the relativeness of equipment combination and $CO_2$ emission by calculate $CO_2$ emission follow to equipment combination on earth-work which is the process emitted most $CO_2$ among railway bedding construction.
