  • Environmental Impact Assessment (EIA) in Korea has worked toward environmental conservation and decision making since the Environmental Impact Statement of 1981. In order to implement the EIA process effectively, we have developed a system for and various methods of EIA. Among these methods, the Environmental Information System, which was introduced recently in Korea, can be used to integrate geographic and attribute data effectively. This study includes methods by which we may use the Environmental Information System. First of all, it explains building EIA factors on the natural environment, the living environment, and the socio-economic environment defined by Environmental Impact Statement regulations in Korea. This study also presents some applications of the assessment methods concerning suitability analysis of landfill sites. Finally, it shows the effectiveness of the Environmental Information System in odor impact assessment. Based on these analysis, the study makes some conclusions for the applications of the Environmental Information System.

  • In this study, LCA(Life Cycle Assessment) on 'Saemangum CSO Project' was carried out to evaluate environmental impact which occurred during the construction and operation periods and the potential environmental impact reduction was analyzed by comparing production and reduction level of pollution loads. LCA was conducted out according to the procedure of ISO14040 which suggested Goal and Scope Definition, Life Cycle Inventory Analysis, Life Cycle Impact Assessment and Interpretation. In the Goal and Scope Definition, the functional unit was 1 m3 of CSO, the system boundary was construction and operation phases, and the operation period was 20 years. For the data collection and inventory analysis, input energies and materials from civil, architecture, mechanical and electric fields are collected from design sheet but the landscape architecture field is excepted. LCIA(Life Cycle Impact Assessment) was performed following the procedure of Eco-Labelling Type III under 6 categories which were resource depletion, eutrophication, global warming, ozone-layer destruction, and photochemical oxide formation. In the result of LCA, 83.4% of environmental impact occurred in the construction phase and 16.6% in the operation phase. Especially 78% of environmental impact occurred in civil works. The Global warming category showed the highest contribution level in the environmental impact categories. For the analysis on potential environmental impact reduction, the reduction and increased of environmental impact which occurred on construction and operation phases were compared. In the case of considering only the operation phase, the result of the comparison showed that 78% of environmental impact is reduced. On the other hand, when considering both the construction and operation phases, 50% of environmental impact is increase. Therefore, this study showed that eco-friendly material and construction method should be used for reduction of environmental impact during life cycle, and it is strongly necessary to develop technology and skills to reduce environmental impact such as renewable energies.

  • Environmental Impact Assessment(EIA) in Korea has developed as a tool for environmental conservation and decision making since Environmental Impact Statement(EIS) preparation in 1981. For effective implementation of it, we do system development and method enhancement continuously. The recently introduced GIS (Geographic Information System) can integrate geographic and attribute data, which will be applied to scoping, assessment, and alternative assessment, etc. in EIA. This study has three major components. First, it explains building of EIA factors of natural environment, living environment, and socio-economic environment of the study area defined in EIS preparation regulation. Second, the study presents applications of assessment method concerning suitability analysis of landfill site using GIS. Finally, it shows integration of GIS and odor impact assessment. Based on these analysis, the study makes some recommendations and conclusions.

  • Purpose: A lot of active researches have addressed the impact of a building on global environment, but most of the researches focus on a residential building and a large office building. Hereupon, this study assessed the impact on environment quantitatively through the analysis of input materials targeting a school building. Method:This study calculated embodied energy of input materials suggested in a construction statement on a school building using the input-output analysis. This study finally carried out environmental impact assessment by applying LCIA DB shown in the preceding researches to the calculated embodied energy. Result: The analysis result revealed that the environmental impact per unit area(/$m^2$) at a school building was $4.11E-02PE{\cdot}yr$, among which Construction was found to be $3.59E-02PE{\cdot}yr$, being analyzed to account for about 87% of the total environmental impact. Also, as a result of detailed environmental impact, the impact on global warming among the total environmental impact was analyzed to be high, accounting for about 76%.

  • Small-scale environmental impact assessments have limitations in terms of survey duration and evaluation resources, which can hinder the assessment and analysis of the current situation. In this study, we propose the use of drone technology during the environmental impact assessment process to supplement these limitations in the current situation analysis. Drone photography can provide rapid and accurate high-resolution images, allowing for the collection of various information about the target area. This information can include different types of data such as terrain, vegetation, landscape, and real-time 3D spatial information, which can be collected and processed using GIS software to understand and analyze the environmental conditions. In this study, we confirmed that terrain and vegetation analysis and prediction of the target area using drone photography and GIS analysis software is possible, providing useful information for environmental impact assessments.

  • Recently, construction industry makes a great effort on minimizing the environmental impact. While various environmental-friendly technologies are applied to the operating phase of buildings, few equipment or machinery are partly used during the construction phase. For this reason, this study carried out a comprehensive analysis on environmental-friendly technologies for the whole construction process. In this study, appropriate environmental-friendly technologies of each construction activity were elicited to improve the environment of construction sites. Environmental-friendly technologies and construction activities were selected by professional consultation and descriptive statistics analysis, and proper environmental-friendly technologies were elicited from Cross-Impact Analysis. As a result, waste disposal and recycling technology was highly effective for demolition work while development of replacing materials was for reinforced concrete work.

  • The choice of economic development over environmental protection has been used to explain the decline in the quality of the environment in developing countries. The authors reject this explanation and propose a theory of negligence to explain this decline. They point to the advantages of environmental impact assessments in dealing with the problem of negligence and presents case studies from four countries. Organizational models for Environmental Impact Assessments in Developing Countries are proposed as useful policy measures.

  • Mitigation measures in EIS are the important factors in the effectiveness of EIS. This paper analyzed the content of mitigation measures described in the 30 EISs selected, using 7 analysis items in order to discover the degree of effectiveness of mitigation measures. 30 EISs used in this study were selected through variance maximization strategy, and the 7 analysis items were; 1) thoroughness of mitigation content, 2) quantification of mitigation content, 3) explicit description of mitigation effect, 4) likelihood of mitigation effect, 5) impacted area of mitigation effect, 6) time frame of mitigation effect, and 7) environmental impact of mitigation measures. The results showed that the effectiveness of mitigation measures in the analyzed EISs was relatively low both in the appropriateness and in the specificity. It was suggested that in order to improve the appropriateness of EIS as a decision making tool, the effect of mitigation measures, as well as the mitigation measures themselves, should be studied and described more thoroughly and specifically.
