Post-kyoto regime has been discussing with the GHG reduction commitment. GHG energy target management system also has been applied for the domestic measures in the country. Universities are major emission sources for GHG. It is very important for campus to built the GHG inventory system and estimate the potential GHG emission reduction. In general, GHG inventory on the campus was taken by the IPCC guidance with the classification of scope 1, 2, and 3. Electricity was the highest portion of GHG emission on the campus as 5,053.90 $tonsCO_2eq/yr$ in 2009. Manufacturing sector was the second high emission and meant GHG in laboratory. Potential GHG reduction was planned by several assumptions such as installation of occupancy sensor, exchanging LED lamp and photovoltaic power generation. These reduction scenarios was simulated by LEAP model. In 2020, outlook of GHG emission was estimated by 17,435.98 tons of $CO_2$ without any plans of reduction. If the reduction scenarios was applied in 2020, GHG emission would be 16,507.60 tons of $CO_2$ as 5.3% potential reduction.

This study examines the contribution level of greenhouse gas(GHG) emission reduction and installation costs of renewable energy facilities. The GHG emission forecasts and industrial structures in the 16 regions of Korea are then analyzed to identify the proper supply of renewable energy sources for each region. The results show that water power is the most effective and efficient renewable energy source to reduce GHG emissions, followed by sunlight, wind power, geothermal heat, and solar heat, respectively. The 16 regions are then categorized into 4 groups based on their GHG emission forecast and industrial structure: high emission and manufacturing group, low emission and manufacturing group, low emission and service group, and high emission and service group. The proper supply of renewable energy sources for each group is then determined based on the contribution level and cost efficiency of GHG emission reduction.

United Nations Framework Convention on Climate Change(UNFCCC) is one of the international environmental convention with the goal of stabilizing Greenhouse Gas(GHG) concent in the atmosphere and preventing potentially dangerous change in the earth's climate. The purpose of this convention is to reduce fossil fuel consumption and to prevent GHG emission. The Republic of Korea was one of the Annex-II parties submitted its national communication to the UNFCCC. As a developing county, there is no GHG emission reduction commitments made by South Korea during first commitment period(2008~2012). On the contrary, South Korea' status as an OECD member, joining in 1996, ranks 6th in GHG emission. Furthermore the rate of increase of GHG is first among OECD countries in year 2005. As a result, Korea will probably be incorporated into Annex-I in second commitment period (after 2013). So, Korea government established and announced Voluntary GHG Reduction scheme to reduce emissions of 4%(accounting for 30% reduction base on Business As Usual) from the 2005 level by the year 2020 for mitigation of reduction duty impact. In specific case of Korea, transportation section occupied almost 21% of total energy consumption and nearly 17% of total GHG emission at 2005, so systematic emission management is required. To do so, in this research, we focus on systematic way of GHG management system to handle GHG reduction duties in Railroad section.

The new climate regime for practical reduction in green house gas(GHG) emissions was launched in Paris at Dec. 2015. The Korea government would make various policies and plans in order to achieve the BAU 37 % emission reduction goals by 2030. In this study, the current situation and the possible corresponding methodology to the GHG emission reduction of Korea paper industry were investigated. Although the GHG emission reduction in KOREA paper industry has been successfully conducted compared with other industries until now, the more efforts for controlling GHG emission would be required to meet the new climate regime. The efficiency of various GHG reduction projects conducted by Korea paper companies was evaluated to find efficient way for GHG reduction. The certified methodologies of the external project based offset systems in Korea GHG emission trading scheme were also reviewed for providing the possible way to develope tailored methodology to the Korea paper industry.

In Korea, various efforts to cope with the Post-Kyoto system have been recently performed because a duty for the GHG(Greenhouse Gas) reduction may be allocated from 2013. Especially, the role of railroad has been strengthened to decrease total GHG emission of transportation system. Therefore, it is necessary to investigate the GHG emission and the reduction strategies of railroad. The purpose of this study was to develop the calculation method of GHG emission released from railroad. Main source of GHG emission was the energy consumption of railroad vehicle and infrastructure. Based on the emission factor and the equation reported in IPCC 2006 guideline, the total GHG emission of railroad was about 1.4 million tons CO2e in 2007. Using this calculation method, the GHG data of railroad can be calculated quantitatively and managed systematically in the future.

Quantifying greenhouse gas (GHG) emissions in the waste sector is important to evaluating measures for reduction of GHG emissions. To forecast GHG emissions and identify potential emission reduction for GHG emissions, scenarios applied with environmental policy such as waste reduction and structural change of waste treatment were developed. Scenario I estimated GHG emissions under the business as usual (BAU) baseline. Scenario II estimated GHG emissions with the application of the waste reduction policy while scenario III was based on the policy of structural change of waste treatment. Scenario IV was based on both the policies of waste reduction and structural change of waste treatment. As for the different scenarios, GHG emissions were highest under scenarios III, followed by scenarios IV, I, and II. In particular, GHG emissions increased under scenario III due to the increased GHG emissions from the enhanced waste incineration due to the structural change of waste treatment. This result indicated that the waste reduction is the primary policy for GHG reduction from waste. GHG emission from landfill was higher compared to those from incineration. However, the contribution of GHG emission from incineration increased under scenario III and IV. This indicated that more attention should be paid to the waste treatment for incineration to reduce GHG emissions.

The Climate Change has been emerged as one of the most important social and economic issues and is affecting our daily life. The Post-Kyoto Protocol aims to reduce GHG(Greenhouse Gas) emission and mitigate climate change. Under this protocol, developed countries which are classified as Annex I implements programmes and strategies confronting against the climate change. South Korea has set voluntary GHG reduction goal of 30% reduction compared to BAU(Business As Usual) in 2020 and prepares National GHG inventory system and Negotiated Agreements(NA) with industries. It will affect seriously to industry and transport sector and its obligation to reduce GHG emission will be strengthened gradually. Therefore, there will be large impact on industry structure. In Korea, various strategies against climate change are being prepared as researches of development of GHG emission reduction technologies and integrated GHG emission management system in transport sector. In this study, strategy on climate change in transport sector is proposed by being based on developed countries' respond to climate change in transport sector.

The Energy and Green House Gas target management system was launched by the Korean Government in 2010. The Korea Emission Trading System will start in 2015. Therefore, simultaneous pursuit of energy saving and greenhouse emission reduction through energy use rationalization is an important obligation of Korean engineers, who import about 97% of domestic energy consumption. Economic analysis of the GHG emission reduction methodologies registered and approved by Korea Voluntary Emission Reduction (KVER) program was conducted. The results for waste heat recovery employed in an energy intensive pulp, paper and wood industry were reported. The emission reduction intensities were 9.7 kg $CO_2$/ton_pulp production. Net Present Value analysis showed that the GHG emission reduction was economically beneficial with an internal rate return of 60%. The results of exergy analysis indicated that the second law efficiencies of waste heat recovery system employed in KVER program were 77.3% and 53.6%. NPV decreased as the exergy decreased.
