그간의 성과와 과제 : 2012년은 우리 정부가 저탄소 녹색성장을 새로운 국가발전 비전으로 선언하고 환경과 경제가 상생하는 사회로의 전환을 위해 다양한 정책을 적극적으로 추진한지 5년차를 맞이하는 해이다. 그동안 우리나라는 녹색성장을 국제적인 화두로 제시하고 온실가스의 자발적 감축목표 발표, G-20 정상회의 개최 등을 통해 국제사회에서 향후 인류의 발전방향을 제시하는 주도적인 역할을 수행하는 국가로서 위상을 높여 왔고, 국내적으로는 4대강 사업 등을 통해 기후변화에 대한 대응능력을 높이고 세계적인 금융 경제 위기 속에서도 안정적인 성장을 지속하는 성과를 거두었다. 환경적인 측면에서도 2007년과 비교하여 수도권 미세먼지 농도를 $58{\mu}g/m^3$에서 2011년에는 $50{\mu}g/m^3$으로 개선하고, 상수도 보급률과 하수도 보급률의 경우에도 2007년 각각 92.1%, 87.1%에서 2011년에는 94.5%, 90.3%로 제고하는 성과를 거두었다. 그러나, 세계적 경기 침체로 인해 국민들이 녹색성장의 성과를 체감하는 데에는 한계가 있었던 것이 사실이며, 4대강 사업이 소기의 목표를 달성하기 위해서는 변화된 환경에 맞는 수질관리시스템을 차질 없이 마련 시행하고, 도시에 비해 낮은 농어촌의 상하수도 보급률과 서비스 수준을 제고하는 등 여전히 해결해야 할 과제들 또한 상존하고 있는 것이 사실이다.

Low-carbon Green Growth is highlighted as the main issue from in and outof Korea. Recently Korean government and local goverment constructed a master plan and related database. Considering this as a starting point the carbon gross emission has become an important factor in the city planning and management of local goverment unit. This research was focused on the analysis of carbon gross emission and the environment of carbon occurrence using statistics and digital forest map for the Gyeonggi-do. Further research need to analysis the carbon absorption using satellite image for periodic database. These database will be available basic data for the policy making.

This study analyzes United Nations Framework Convention on Climate Change and domestic-foreign support policy for renewable, also confirms the need for sound and sustainable development to minimize adverse impacts on the environment. Main source of greenhouse gas emissions leading to global warming needs to be resolved through the introduction of renewable energy system by developing low-carbon city. Case studies show the directions for practical response to climate change on the basis of introduction of renewable energy. This case studies can be served as the base model that reduces greenhouse gases with the introduction of renewable energy facilities in the new land development project and obtains economic benefits from CDM project.

최근 철도는 미래의 핵심교통수단이자 저탄소 녹색성장을 대표하는 교통수단으로 주목받고 있다. 그 중 자기부상열차는 바퀴 마찰에 따른 소음 진동 분진이 없는 차세대 교통수단이며, 이를 지지하는 구조물(교량)은 열차의 운행 안정성(동적거동)을 고려한 설계가 필요하다. 또한, 상부 구조물은 자기부상열차의 연행이동등분포하중을 지지하며, 이러한 하중조건을 갖는 차량이 운행할 때 상부 구조물은 설계기준사항들을 만족해야한다. 도시형 자기부상철도 토목구조물 설계기준에 의하면 도시형 자기부상철도의 운행 안정성(동적거동)을 평가하기 위한 항목들로 대상 구조물의 고유진동수, 승차감을 고려한 연직처짐 등이 요구된다. 따라서, 본 연구에서는 자기부상열차의 실 열차하중을 고려하여 연행이동등분포하중으로 철도교량의 동적거동을 검토하였으며, 설계기준을 적용하여 대상 철도 교량의 운행 안정성을 평가하였다.

In order to make the best choice for $CO_2$ abatement using renewable energy technologies, it is important to be able to adapt these technologies on the basis of their sustainability, which may include a variety of environmental indicators. This study examined the comparative sustainability of renewable technologies in terms of their life cycle $CO_2$ emissions and embodied energy, using life cycle analysis. The models developed were based on case studies of bioenergy pilot plant in P city of Kyungki province. Final results were total emission of $CO_2$ in Pocheonsi is 670,041 $tCO_2$, around 500,877 $tCO_2$ for electricity and for heat generation, and 169,164 $tCO_2$ for transportation. When used $1,984\;m^3$/day of waste (pig manure etc.) and operated CHP with wood chips of 144,664 ton/year, the $CO_2$ emission in P city was left as is an emission of 449,274 $tCO_2$ and an abatement of $CO_2$ in this region was increased by 32.9%.

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.

In this study, Urban Climate Simulation was performed by 3-Dimensional Urban Canopy Model. The characteristics of urban climate was analyzed combining artificial land coverage, building size, heat production from the air conditioning and topographic conditions as physical variables which affects urban climate characteristics. The results are as follows. (1)The aspects of the urban climatal change is derived to be related to the combination of the building coverage ratio, building height and shading area. (2)Whole heat generation was influenced by the convective sensible heat at the lower building height and by the artificial heat generation at the higher one over 20-story building influence to some extent of the building coverage ratio. The effect of the altitude is not more considerable than the other variables as below $1^{\circ}C$ of the air temperature.

The purpose of this paper is to draw main characteristics of local climate change plans of 8 pilot cities through a serious of comparative analyses. The results of the analyses on the mitigation plans and the adaptation plans are the followings; Firstly, climate change plans have two types of distinctive frameworks. Secondly, vision, objectives, and main strategies are composed of main key words. The key words of mitigation plans are low carbon, GHG, green city, energy, and green growth. Adaptation, ecosystem, healthy, safe, disaster, water are the key words that frequently shown in adaptation plan. Thirdly, the mitigation plans tend to place emphasis on transportation and common area. The adaptation plans tend to weigh on water control and forestry. The main characteristics of both mitigation plans and adaptation plans of 8 pilot cities are summarized and policy implications are suggested.

Sustainability has already become one of the most important innovation policy agendas in many countries. Korea has tried to emulate this global trend in various forms, unfortunately with little success. A very strong tradition of centralized administration in Korea has meant that local communities and municipalities have remained more or less passive in tackling their own sustainability issues and problems. In recent years, with the impetus of huge democratization attempts in Korea since the late 1980s, there have been some local attempts to remedy these imbalances since the early 2000s. A series of local experiments to try and test green alternatives against the very hostile environment have been implemented, with varying degrees of success. This study analyzed cases of transition experiment to sustainable socio-technical system such as MUSIC project, Low Carbon Green Village and Citizens' Sunlight Power Stations. To draw politic meanings for sustainable socio-technical system, these content, process of conversion and feature were examined.

Renewable and unutilized energy (biogas power generation, wind power, solar, small hydro-power, sewage heat source, etc.) seems to be suitable to install for the sewage treatment facilities. There are 357 sewage treatment plants in 2007. 17 plants among these have been operating for self-supporting energy by using solar power, small hydro-power and biogas in 2008. Newly built sewage treatment plant of 96,000 $m^3$/day for a newtown is expected to get up to energy consumption of 10 GWh/yr. If solar energy, small hydro-power and biogas-equipments were applied to the new treatment plant, self-supporting energy of the new sewage treatment plant will get up to 56.1%. As a results, about 2,379ton $CO_2$/yr $CO_2$ emission reduction can be expected by using renewable energy. These efforts for self-supporting energy will lead sewage treatment plant to new energy recycle center.
