Climate change induced by global warming has recently begun to inspire developed nations to introduce a new paradigm, called the sustainable (Green) growth, which entails both the prevention of environmental pollution and the attainment of sustainable growth. The sustainable (Green) growth is founded upon environmental factors that drive a new force of economic progress without deteriorating nature. Thus, the conservation of the environment under the new growth paradigm can be compatible with economic growth, although this was not feasible under conventional economic relations, called the Environmental Kutzets Curve. Sustainable (Green) finance is essential to achieving Green growth efficiently and effectively. Since the financial system for Green growth is at the early stage of implementation, the application of strategies for sustainable (Green) finance should be preceded by proper initiation and protection from the government. In order to establish a feasible strategy for financing green growth, we suggest an effective financial supporting system, taking different operational forms upon the broader stage of technological progress in each individual company.

국가간 지역간 물의 이동을 개념화하여 물 부족 현상을 정치경제학적 관점에서 접근하려는 가상수(virtual water) 연구가 국제적으로 진행되고 있다. 가상수를 양적 측면에서 산정하여 정확한 물 수지를 파악하면 수자원에 대한 국가의 계획과 전략 수립에 매우 유리한 여건이 조성된다. 우리나라의 국가계획인 수자원장기종합계획은 국가 간의 물 이동을 고려하지 않고 국내에서 발생하는 용수의 수요와 공급 측면만을 산정하고 있다. 그러나 현재에도 국내에서 소비하는 농산물과 축산물의 상당량은 수입에 의존하고 있으며, 향후 국제교역과 FTA의 확대 등으로 그 의존도는 더욱 증대될 것으로 추산된다. 따라서 국가 간 물 이동에 대한 양적 규모를 파악하여 국가전략을 수립하는 기초자료로 활용하기 위한 연구가 필요하다. 이에 본 연구에서는 산업연관분석법을 활용하여 국내 산업별(제조업, 서비스업) 가상수를 산정하여 국가 수자원계획 수립에 필요한 기초자료로서 제공하고자 한다. 산업연관분석(Inter-industry analysis)은 산업연관표를 바탕으로 산업 간의 상호 연관관계를 수량적으로 파악하는 방법이다. 이를 가상수 산정에 활용하여 직접수와 간접수를 포함한 물의 전체 사용량을 산정할 수 있다. 본 연구에서는 각 산업의 용수량을 총 생산량으로 나누어 물 강도($m^3$/원)를 계산하고, 생산유발계수와 최종수요를 곱하는 방식으로 산업별 가상수량을 산정하였다. 산업별 가상수 산정 결과는 경제총조사의 용수비와 산업연관표의 생산유발계수를 적용하였으며, 제2차 산업인 제조업 분야의 연간 가상수량은 60.4억 $m^3$, 제3차 산업인 서비스 분야의 가상수량은 연간 43.1억 $m^3$으로 분석하였다. 또한 향후 10년의 OECD 기술수준 제품군별 무역수지 전망을 고려한 결과, 기술수준 중 및 고 기술제품의 가상수 수출량이 2020년에는 2010년에 비해 약 3배 증가하는 것으로 산정하였다. 이와 같은 방법으로 산정된 산업별 가상수는 각 산업의 물 사용량을 추정하고 산업 전반의 수자원 활용도를 파악하는데 이용 가능하다. 더불어 국제 환경 및 기후변화가 반영된 가상수 시나리오 연구를 통해 장래 용수 수요변화예측 등 효과적인 물 관리 정책 수립에 기여할 수 있다.

We applied general equilibrium model to analysis the economic impact of international emission trading by sector and the efficiency of the Convention to study whether Climate Change Convention satisfy the efficiency. We divided the world as 4 groups : USA, OECD members w/o USA (OEC), Former Soviet Union (FSU) and Developing countries (DEV). Compared to no trading, global trading would accomplish the same environmental effect with less cost as much as 97.8 billion$, which is the surplus of trading. However, half of it is taken by USA and 20% by OEC. FSU and DEV have only 18% and 10%. This result suggest the two things. First, the emission trading is effective as far as the participation of developing countries are guaranteed. If they do not take part in the coalition and emit the leakage, it may threaten the stability of the international trading coalition. Second, we found the logical ground of the side payment for developing countries. The permit buying countries take more share of the surplus under the emission trading, while the energy sector of developing countries shrinks to sell permits, which may adversely affect to economic growth of the countries. Therefore, the Annex-I countries need to provide side payment to lead the participation of the developing countries.

This study analyzed changes on the best condition of temperature and relative humidity for making artificial snows in the Yongpyong Ski Resort using data from Daegwallyeong. Depth of snowfall and snowfall days have decrease since 1990s. If the Yongpyong Ski Resort has only to depend on natural snows, it would be difficult to make and maintain ski slope. There are two times of snowmaking during ski seasons: one is the first snowmaking (October-November) for opening ski slopes and the other is the reinforcement of snowmaking (December-March) for maintaining snow quality during the seasons. Days having the best condition for the first snowmaking (daily minimum temperature below $-1^{\circ}C$ and daily average relative humidity 60 to 80 percent) decreased after 1970s. Days having the best condition for the reinforcement of snowmaking also decreased. While temperature changes are more evident than humidity changes for the first snowmaking, humidity changes are more obvious than change of temperature for the reinforcement of snowmaking. In the future climate projection by A1B scenarios, the length of ski seasons projected to decrease a 10 to 40 percent against the period of 1973-2008. The climate condition for the snowmaking projected to be poor, especially the due to increase of temperature.

The Government of South Korea has continued its effort to fixate virtuous circle of economic growth and climate change response to cope with international demands and pressure to commitment for greenhouse gas reduction effectively. Nationally, Korean Government has established "Enforcement of the Framework Act on Low carbon, Green Growth"(2010. 4. 13) to implement national mid-term GHG mitigation goal(30% reduction by 2020 compare to BAU), which established the foundation for phased GHG mitigation by setting up the sectoral and industrial goal, adopting GHG and Energy Target Management System. Also, follow-up measures are taken such as planning and control of mid-term and short-term mitigation target by detailed analysis of potential mitigation of sector and industry, building up the infrastructure for periodic and systematic analysis of target management. Likewise, it is required to establish more accurate, reliable and detailed sectoral GHG inventory for successfully establishment and implement the frame act. In comparison to the $CO_2$ emission, Especially fluorinated greenhouse gases (HFCs, PFCs, $SF_6$) are lacking research to build the greenhouse gas inventories to identify emissions sources and collection of the applicable collection activities data. In this study, with the refrigeration and air conditioning sector being used to fluorine refrigerant(HFCs) as the center, greenhouse gas emission estimation methodology for evaluating the feasibility of using this methodology look over and mobile air conditioning, fixed air conditioning, household refrigeration equipment, commercial refrigeration equipment for the greenhouse gas emissions were calculated. First look at in terms of methodology, refrigeration and air conditioning sector GHG emissions in developing country-specific emission factors and activity data of the industrial sector the construction of the DB is not enough, it's 2006 IPCC Guidelines Tier 2a (emission factor approach) rather than the Tier 2b (mass balance approach) deems appropriate, and each detail by process, sectoral activity data more accurate, if DB is built Tier 2a (emission factor approach) can be applied will also be judged. Refrigeration and air conditioning sector in 2009 due to the use of refrigerant greenhouse gas emissions ($CO_2eq.$) assessment results, portable air conditioner 1,974,646 ton to year, fixed-mount air conditioner 1,011,754 ton to year, household refrigeration unit 4,396 ton to year, commercial refrigeration equipment 1,263 ton to year was estimated to total 2,992,037 tons.

Gangnam-gu, where the survey of residents' consciousness has been made in this study, is the district shows the highest rate of the energy consumption and greenhouse gas emission per unit area except some industrial districts such as Gwangyang, Ulsan, and Pohang. The greenhouse gas emission amount of Gangnam-gu is 4,863,765 $tCO_2$ which accounts for 10 % of the total discharging amount of Seoul, 50,330,356 $tCO_2$, which is ranked the top greenhouse gas emission rate in the commercial category and the 2nd place in the household category. The average recognition rate for the 5 subjects of the global warming phenomenons has indicated to be 83.58%. A survey questioning about the main agent to reduce the greenhouse gas, in all age groups except 20s have replied that it should be done by themselves, the residents of Gangnam-gu. For the question of the role of local government to respond to the climate change, the necessity of establishing infrastructure which is suitable for walking and biking. For the other question about the educational facilities to cope with the climate change, many answered the relevant education should be processed from the middle and high schools. For the practical activities in daily life to respond to the climate change, many replies have shown that the energy and resource conservation has been practiced pretty well broadly, but the ecomileage (former carbon mileage) has not been practiced well. Also, many replies have pointed that there were no benefits or rewards for the people who practiced the eco-mileage in their daily lives, which indicates that a kind of incentive is necessary for the efforts to respond to the climate change from the local government to execute the policy substantially and effectively. This study has the purpose to search the political countermeasures to improve the potentiality to reduce the green house gas emission rate through the residents conscious survey about climate change and the political solution by the local government to improve the certain items which showed the lower awareness rate.

The importance of environmental industry was recognized as a major issue for the environmental problems (climate change, exhaustion of fossil fuels) of the 21st century. Many country and korea as well are exerting an effort to make plans to develop the environmental industry, expand the domestic market, and make it a global industry. According to this trend, the gyeongbuk province has also designated the environmental industry as a strategic industry with high potential for development when recognizing new growth industries. Gyeongbuk province is faced with a number of unsolved tasks and has not quite grasped current situations of the environmental industry. Based on the policy tasks, the detailed plans for the environmental industry in the gyeongbuk province include: establishing a new organization which will be in charge of various works or strengthening the current organization to expend the supporting developing organization for the environmental industry and the efficiency guidelines.

In order to identify the economic impacts of forest-related industry on the national economy in general and the linkages between forestry and its related industries, an input-output analysis was conducted using the 2015 Input-Output Tables of the Bank of Korea. Production inducement effects are relatively high in paper products, lumber, and silviculture and relatively low in other wood industries. Value-added inducement effects are relatively high in silviculture and log production. With respect to the wood products industry, forward linkage effects are higher and backward linkage effects are lower. A Ritz-Spaulding multiplier analysis revealed that the growth of wood products production has only a modest impact on the growth of forestry. How to increase the linkage between forestry and the wood products industry is one of the most important policy tasks in Korea, given that it affects forest ecosystem management and climate change mitigation efforts.
