The goal of the UN Framework Convention on Climate Change (UNFCCC) is to stabilize atmospheric CO2 concentration for preventing global warming in future. However, there are many unknown factors regarding stabilization of CO2 concentration. What level of concentration should be appropriate to prevent global warming？ When should we stop the increase of CO2 concentration\ulcorner What kind of countermeasures of reducing CO2 emission will be available for CO2 stabilization？(omitted)

Carbon dioxide Capture and Storage (CCS) is one of the key players in greenhouse gas (GHG) reduction portfolio for mitigating climate change. CCS makes simultaneously it possible not only to reduce a huge amount of carbon dioxide directly from the emission sources (e.g., coal power plant) but also to maintain the carbon concentrated-energy and/or industry infrastructure. Internationally, the United Nations Framework Convention on Climate Change (UNFCCC) is dealing the agenda for considering the possibility of including CCS project as one of Clean Development Mechanism (CDM) projects. Despite its usefulness, however, there are the controversies in including CCS as the CDM project, whose issues include i) non-permanence, including long-term permanence, ii) measuring, reporting and verification (MRV), iii) environmental impacts, iv) project activity boundaries, v) international law, vi) liability, vii) the potential for perverse outcomes, viii) safety, and ix) insurance coverage and compensation for damages caused due to seepage or leakage. In this paper, those issues in considering CCS as CDM are summarized and analyzed in order to suggest some considerations to policy makers in realizing the CCS project in Korea in the future.

The international community is paying close attention to the climatic changes caused by the meteorological anomalies. In response to such phenomena, after the adoption of the United Nations Framework Convention on Climate Change in 1992, efforts to actively respond to the meteorological changes are proliferating all over the world; even in the Republic of Korea, the issue to tackle the meteorological changes has emerged as a top-priority national agenda. In the year of 2008, after the declaration of the low-carbon, green-growth paradigm by the government, the UNFCCC COP15 has announced a 30% reduction target of the emission of the greenhouse gases by 2020 as compared to the "Business As Usual, BAU" and has also confirmed, as a commitment plan to achieve reduction in the emission of greenhouse gases, the reduction target of greenhouse gases for all sectors, industries and years. (26.9% for buildings) Since the construction of the new apartment houses in the year of 2001, the "Building Energy Efficiency Rating", has been applied to newly constructed building complexes, built in 2010; the accumulated emission reduction has been evaluated at around 450,000toe and the accumulated carbon dioxide emission reduction is at $826,000tCO_2$ And through the prediction of these values under various scenarios (New construction, new construction / expansion of existing uses, when transferred to 1stgrade), the effects on the degree of reduction of greenhouse gases by the increased certification of the Building Energy Efficiency Rating are an alyzed and it is our aim to express the importance of the certification system capable of carrying out a quantitative evaluation of the building energy in order to establish the strategy to reduce the emission of carbon dioxide.

The United Nations Framework Convention on Climate Change and the corresponding national low-carbon policy should be grounded on the scientific understanding of climate sensitivity to the increase in CO2 concentration. This is, however, precluded by the fact that current estimates of the climate sensitivity highly vary. To understand the scientific background, limitations, and prospects of the climate sensitivity study, this paper reviews, as objectively as possible, the most recent results on the sensitivity issue. Theoretically, the climate sensitivity hinges on climate feedbacks from various atmospheric and surface physical processes. Especially cloud and sea-ice processes associated with shortwave radiation are known to have largest uncertainty, resulting in an inaccurate estimation of climate sensitivity. For this reason, recent observational studies using satellite data suggest sensitivity lower than or similar to those estimated by climate models (2-5 K per doubled CO2).

The climate change has become one of the most important global issues that require global responses. As one of the leading contributions to climate change, greenhouse gas emissions and Ballast Water Management have attracted growing attention from the international community. The International Maritime Organization (IMO) received its mandate to regulate International Convention for the Control and Management of Ships' Ballast Water and Sediments in 2004. The convention requires that every vessel must be equipped Ballast Water Management System (BWMS) in 2017. Based on this situation, this study aims to analyze the present state and data from the exports of BWMS(HS842121). The results show that as the most leading country in the field, Germany has the largest market share (14.33%), Revealed Comparative Advantage (RCA) index 1.76, and Trade Specialization Index (TSI) 0.636 in the world. The two other leading countries such as Denmark and Netherlands follows the ability of Germany. The Korean market share of HS842121 shows market share (5.98%) which is a bit bellow high compared to other countries. However the RCA index (1.85) presents the state of comparative advantage. In addition, Korea's TSI index (0.453) indicates that it is in the state of export specialization. The Korean BWMS and Shipbuilding industry maintain the state of export specialization. They are also in the state of import specialty. For Korea to raise its export competitiveness and to ensure shipbuilding competitiveness, it is necessary to intensify supporting systems and related policies.

According to the United Nations Framework Convention on Climate Change (UNFCCC), all parties have to submit the national GHG inventory report. Estimating carbon stocks and changes in Land Use, Land-Use Changes and Forestry (LULUCF) needs an activity data and emission factors. So this study was conducted to develop carbon emission factor for Robinia pseudoacacia L., Betula platyphylla var. japonica, and Liriodendron tulipifera. As a result, the basic wood density ($g/cm_3$) was 0.64 for R. pseudoacacia, 0.55 for B. platyphylla, and 0.46 for L. tulipifera. Biomass expansion factor was 1.47 for R. pseudoacacia, 1.30 for B. platyphylla, and 1.24 for L. tulipifera. Root to shoot ratio was 0.48 for R. pseudoacacia, 0.29 for B. platyphylla, and 0.23 for L. tulipifera. Uncertainty of estimated emission factors on three species ranged from 3.39% to 27.43% within recommended value (30%) by IPCC. We calculated carbon stock and change using these emission factors. Three species stored carbon in forest and net $CO_2$ removal was $1,255,398\;t\;CO_2/yr$ during 5 years. So we concluded that our result could be used as emission factors for national GHG inventory report on forest sector.

Recent industrial development and technological breakthroughs have made our life much more convenient, however, at the cost of environmental degradation resulting from indiscreet focus on development in combination of disregard of impact on eco system. Notably, global warming is one of the most serious environmental issues, triggering attention for environmental protection in Korea and elsewhere. To address such issues, nations around the world are beefing up environmental regulatory framework such as UNFCCC(United Nations Framework Convention on Climate Change) to tackle environmental challenges from global perspective. Against the backdrop, Korea has been engaging actively in global initiatives to reduce climate change, ratifying UNFCCC in 1993 and the Kyoto Protocol in October, 2002. However, unlike the government responding to environmental degradation in earnest, construction industry is far from making efforts to reduce wastes. Construction waste is a source of environmental deterioration world wide and adds to the aggregate cost that construction companies should assume. Korean construction firms also need to develop initiative aggressively to respond to changes in environmental policies and reduce construction costs. Therefore, this study aims at examining sources of wastes in construction sites and suggest solution in order to prod local construction companies to develop countermeasures.

World Wide Views (WWViews) on Climate and Energy was an experiment of public deliberation which was held in 77 countries with over 10,000 global citizens on June 6, 2015. The coordinator of this project (the Danish Board of Technology with Missions Publiques and the French National Commission for Public Debate) developed the overal procedure, and local partners implemented the actual events in each country on the same day. The coordinator gathered the results of the events from all local sites in order to submit them as global citizens' voice to the COP21 negotiations at the United Nations Framework Convention on Climate Change (UNFCCC) in Paris. This study examines the extent to which such new method of WWViews, standardized at global level to be implemented in different local contexts, achieves its quality of public deliberation (representativeness, transparency, impartial inclusion, deliberativeness, influence) by evaluating the Korean WWViews held in Seoul.
