Global warming has been hot issue world wide. Korea has been dealing with the global issue under the slogan of low carbon and green-growth such as setting national greenhouse gas (GHG) reduction targets and allocation to each industrial sector. Infrastructure construction, in which enormous social overhead capital (SOC) is input, has great role as one of the actions. Road is one of the representative infrastructure and large amount of resources is utilized in its construction, operation and maintenance stage. The estimation methodology of life cycle carbon emissions was developed and applied to a case study of highway currently under construction in this study. Also, total carbon emissions of all the highway in South Korea at present (2009) and cumulative carbon emissions from 2009 to 2020 were estimated using the results of case study.

Roundabout has circular traffic island in the intersection center and is kind of intersection where the automobile bypass circular traffic island. In Korea, the provisional Roundabouts Design Guidelines were published in 2004 by MLTM (Ministry of Land, Transport and Maritime Affairs). This guideline did not discussed domestic traffic circumstance. It just only introduced foreign instances and their guidelines. In addition, the recent National Competitiveness roundabouts as part of the green growth has been concentrated on the interest. In this paper, 90 degree of the 4-legged roundabout was compared with 72 degree, 45 degree, and 30 degree 5-legged roundabouts by micro simulation VISSIM. As a result of analysis, average travel time is decreased when the inscribed circle diameter become bigger the roundabout. 5-legged roundabout until 2,000 volume per hour evaluated to be similar effect at 90 degree of 4-legged roundabout.

The value of Environment is so high and important that no one can estimate it correctly. In the area of Logistics, Environment protection is very important and keen subject for the present and for the future of this country and people. Environmental logistics, similarly used as Green logistics, means the protection of Nature and Environment and reduces all kinds of factors and behaviors that may destroy and deteriorate current Environment. It also include the preservation of Nature and sustainable development. Environmental logistics aims to save natural resources and to promote reuse of all kinds of materials and to increase the utilization of Environment friendly substitute goods. In this paper the concept and characteristics of Environmental logistics were summarized and described. Also the main previous studies were surveyed. Some of important cases and experiences which were introduced and applied in major countries such as Japan, Hongkong, USA and the case of PHILIPS were summarized and analyzed. With these cases and analysis, this paper suggested some alternatives and countermeasures for the improvement of Environmental logistics in terms of 3 dimensions such as Country, Company and Individual level. And a strategy model for enhancement of the Environmental logistics was suggested and limitations of this paper and future research directions were described.

It's been more than 30 years since global warming by the increase in CO2 became a cause celebre worldwide. Recently the government promulgated Framework Act on on Low-Carbon Green Growth and has been continuously putting much effort into saving energy and reducing carbon dioxide emissions such as an international climate change conference to prevent the increase in CO2. However, because most cities are not planned for energy saving, new cities should be planned as the active energy-efficient urban structure for 'sustainable urban development' from a long-term perspective. This study aims to design a new prototype for the sustainable energy-independent and environment-friendly housing estates which is the nation's new vision in the era of the Fourth Industrial Revolution. A study on the energy-independent site planning and the quantitative standardization of its factor will be conducted.
