  • 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.

  • World have been encouraged to develop technologies that contribute to CO$_2$ emission reduction for many years. Those technologies can be categorized into capture, storage or sequestration, utilization, etc. There have been lots of efforts, in Korea, to develop the technology as well. In this paper, the impact factors of the technologies, especially in CDRS (Carbon Dioxide Reduction & Sequestration Center), were selected and were weighed by SMM (Storing Models Method) and AHP (Analytic Hierarchy Process) in order to evaluate the four representative areas of the technologies.

  • 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.

  • Carbon dioxide ($CO_2$) is the greatest contributor among the major greenhouse gases covered by the Kyoto Protocol. Therefore, substantial efforts for the control and reduction of $CO_2$ emissions, including increased efficiency of fossil fuel energy usage, development of energy sources with lower carbon content, and increased reliability on alternative energy sources, are being performed worldwide. However, development and industrial application of $CO_2$ sequestration techniques are needed to meet the requirements of the Kyoto Protocol. Among the $CO_2$ sequestration methods developed, geological sequestration methods such as the storage in deep aquifers, deep coal seams and oil and gas reservoirs and the mineral carbonation is considered most favorable because of its stability and environmental effectiveness. In this review, geochemical concepts and technologic development of geologic sequestration technology, especially the storage in deep aquifers and the mineral carbonation, are discussed. The weakness and strengths for each of geologic sequestration methods, are also reviewed.

  • 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.
