  • Carbon Neutral is one of the magnifying pan-governmental tasks which aim for stabilizing pan-global ecosystem. The purpose of this study is to estimates carbon neutral degree in cities by using capacity of carbon storage, which is carbon sinks, on forest and to develop an indicator that could be utilized in establishing policy related to climate change respond. When the carbon emitted from city has been absorbed or stored, the value of the indicator aiming to achieve carbon neutral could be drawn. The result and implication are as follows. First, while the annual amount of carbon emission in Gyeonggi S city was 18,787 thousand (tons), which was the highest, that of Gyeongbuk U city indicated the lowest with approximately 112 thousand (tons). Second, Gyeongbuk U city represented the largest capacity of annual carbon storage with about 16,748 thousand (tons), whereas the smallest figure was shown in Gyeonggi B city with 151 thousand (tons). Third, as result of the estimation of carbon neutral degree, the value of the indicator in Gyeonggi B city was 3% referring the lowest point, while that of other cities demonstrated over 100%. Forth, it has the possibility to suggest the fixed quantity when the plan for achieving carbon neutral of city is being processed. In the near future, after the completion of the construction projects of greenhouse gas inventory in all local governments, by utilizing the relative dates, the value of the indicator can be calculated and a more general conclusion could be drawn. Moreover, as expanding case studies to all domestic cities, generalness is in need.

  • Climate change lead to environmental pollution caused by the radical economic growth and development of industry. The amount of damage from abnormal climate is increasing rapidly for this reason in Korea. In particular, the cities is a lot of carbon emission quantity from the radical growth. Thus the government present "low carbon green growth" for eco-friendly city planning. As one of the important factors effecting climate change, active researches on land use change is performed. In this study, we knew land use change of each scenarios using land use equilibrium model which is kind of predictive model of land use in Japan. First, we selected study area to Jeju lsland. For this study, indicators for input data were selected and spatial data for input data were established using GIS program. Second, we established future scenarios based in 2040s. There are 2 future scenarios: dispersion scenario, compact scenario. Third, we compared with residential area of current and residential area for future scenarios. Results showed that residential area of the difference between current and dispersion scenario were 1,230 ha and residential area of the difference between current and compact scenario were 1,515 ha. Finally, for comparing carbon dioxide absorption volume between dispersion scenarios and compact scenarios, we calculated carbon dioxide absorption volume according to residential area decreased of each future scenarios. Results showed that carbon dioxide absorption volume in dispersion scenario was 477,878 ton and carbon dioxide absorption volume in compact scenario was 588,606 ton. Therefore, the study showed that land use equilibrium model is expected to put to use for future enhancement in creating data for climate change stabilization.

  • The development of new energy has attracted consideration attention due to the high oil price and environmental problems. In advanced country, they have tried to carry out a long range plan for energy. We need to develop new energy for Low Carbon Green Growth in Korea. The building is 30% among ratio of energy consumption in Korea. And in the past, heating energy was high ratio for energy using at home. But recently, the demand for cooling energy keeps growing due to rising average temperature on the earth and improvement of life quality. In this situation, the energy of lake water and ocean water has studied to utilize in advanced country because of low temperature at underwater. But the study for deep water is still a lot left to do. In this study, we analyzed district cooling system and the present condition. Analyzing the deep lake water cooling system in Toronto, we found an application of district cooling system using deep ocean water. Deep lake water uses heat source for district cooling and water source for city in Toronto. So reducing the initial cost, this city had economic effect. When DLWC was applied at existing building, the heat exchanger was installed instead of cooling tower and refrigerator. And the heat exchanger used to connect main pipe with cool water on city. System using deep ocean water can be applied as a similar way to supply cool water from lake to building.
