The objective of this work was to investigate how carbon sink and sequestration of vegetation and soil in the development project area can impact the land use plan, in addition to carbon emission capacity of the development project when we conduct environmental impact assessment. Especially, we did this work for a development project of solar power plant which would be constructed in forest area. Through this work, we found that 1) the amount of carbon sink and sequestration largely decreased due to reduction of the green area, 2) in terms of carbon sink and sequestration, conservation of natural green area is better than construction of newly vegetated area, 3) biochar application into soil can become an alternative for increase of carbon sink, and 4) even though a solar power production does hugely reduce carbon emissions and offset the carbon sink and sequestration capacity from the forest, it is necessary to consider the public value of the forest(reduction of heat island, habitat etc.) in siting for development area.

Ever since the United Nations Framework Convention on Climate Change(UNFCCC) was agreed to stabilized greenhouse gas(GHG) concentration in the atmosphere at 1992, most countries including Korea have been developing strategic plans and implementing a number of R＆D programs to develop the measures to reduce the emission of GHG. Therefore, it is necessary to investigate the plans and programs for our country to develop more competitive technologies and to be more active and attentive in international meetings. In this paper, the energy policies of advanced countries will be analysed and be compared each other along with the Korean policy. Furthermore, the carbon dioxide reduction and sequestration R＆D programs in the countries will also be studied.

As the sustaindble development becomes the main goal of the global world in the 21st century, it is important that technological innovations should be realized ecologically sound based on co-evolutionalry approach. From this perspective, the trans-disciplinary research method is gaining importance in the evaluation process of public funded R&D, especially in the environmental technology. In our evaluation research on the R&D projects of the $CO_2$reduction and sequestration technology in Korea, we attempt to apply a trans-disciplinary integrated method on the concept of the eco-innovation, the technology push and the market pull. Also, we try to develop the trans-disciplinary indicators of the environmental technology evaluation. This research confirms the necessity of trans-disciplinary research among the three academic perspectives, engineering, social sciences and public policy.

Global warming issues due to the $CO_2$(Carbon Dioxide) become increasing since the Industrial Revolution. After the Kyoto protocol at 1997, nations which have the prearranged quota drives their national project for the reduction of $CO_2$. Korean Government start to the related big projects in the view of three concepts which have consist of the $CO_2$ exhaust reduction on land, $CO_2$ capture and $CO_2$ storage. Furthermore, the storage method putting into depleted region underground is accepted by the London Convention while the ocean diluted method discharging the liquid $CO_2$ into the deep ocean using the long pipe which is towed by the surface vessel is underway for the research steps which means that there are many potentials for the R&Ds that need for the breakthrough. In this paper, the role and example of the Computational Fluid Dynamics for the feasibility study of the $CO_2$ ocean sequestration is mentioned.

이산화탄소($CO_2$)는 기후협약에 관한 교토의정서에서 적시한 온실가스 중에서 가장 중요한 물질이다. 이에 세계 각 국은 화석에너지 사용의 효율성 증가, 저탄소 함량의 에너지원, 대체에너지원 개발 등 이산화탄소 배출량을 조절하고 줄이기 위한 기술 개발에 상당한 노력을 기울이고 있다. 그러나 교토의정서에서 제시한 배출량을 만족시키기 위해서 는 이산화탄소 처분 기술의 개발과 적용이 필수적으로 요구된다. 현재까지 개발된 이산화탄소 처분 기술 중에는 심부 대수층 처분, 심부 석탄층 처분, 유전 및 가스전 처분, 탄산염광물화 처분 등의 지중(지질) 처분 기술이 그 안정성 및 환경적 친화성으로 말미암아 가장 적극적으로 고려되고 있다. 본 논문에서는 이산화탄소 지중 처분 기술, 특히 대수 층 처분 및 탄산염광물화 처분 기술의 지구화학적 개념과 기술개발 동향에 대하여 알아보고 또한 각 지중 처분 기술 의 장점과 단점에 대하여 검토하고자 한다.

As the Kyoto Protocol will come into effect starting February 2005, 55 member countries of the Conference of Parties of the Framework Convention on Climate Change (FCCC) will be under obligation to reduce the emissions of Carbon Dioxide $(CO_2)$ by 5.2 Percent from the 1990 levels before the year 2012. Hence the development of technology to prepare for this has been accelerated in Korea. The effect of technology varies with market size of technology, and it is necessary to control technology development period, according to the size and trend of technology market. Moreover it is essential that market analysis be finished before technology development, because market on the $(CO_2)$ Reduction and Sequestration Technology expands internationally. For that reason, it is needed to analyze domestic market and to consider technology development strategy according to analysis results. In this paper, we analyzed the domestic industry and forecasted the market size, both related to the Reduction and Sequestration Technology on $(CO_2)$ emission, which is the major component of global Green House Gas(GHG).

Forests potentially contribute to global climate change through their influence on the global carbon (C) cycle. The Kyoto Protocol provides for the involvement of developing countries in an atmospheric greenhouse gas reduction regime under its Clean Development Mechanism (CDM). Carbon credits are gained from reforestation and afforestation activities in developing countries. Bangladesh, a densely populated tropical country in South Asia, has a huge degraded forestland, which can be reforested by CDM projects. To realize the potential of the forestry sector in developing countries like Bangladesh for full-scale emission mitigation, the carbon sequestration potential should be integrated with the carbon trading system under the CDM of the Kyoto Protocol. This paper discusses the prospects of carbon trading in Bangladesh, in relation to the CDM, in the context of global warming.
