  • The accelerated pace of climate crisis due to continuous industrialization and greenhouse gas emissions necessitates sustainable solutions that simultaneously address mitigation and adaptation to climate change. Naturebased Solutions (NbS) have gained prominence as viable approaches, with Green Infrastructure being a representative NbS. Green Infrastructure involves securing green spaces within urban areas, providing diverse climate adaptation functions such as removal of various air pollutants, carbon sequestration, and isolation. The proliferation of Green Infrastructure is influenced by the quantification of improvement effects related to various projects. To support decision-making by assessing the climate vulnerability of Green Infrastructure, the U.S. Department of Agriculture (USDA) has developed i-Tree Tools. This study proposes a comprehensive evaluation approach for climate change adaptation types by quantifying the climate adaptation performance of urban Green Infrastructure. Using i-Tree Canopy, the analysis focuses on five urban green spaces covering more than 30 hectares, considering the tree ratio relative to the total area. The evaluation encompasses aspects of thermal environment, aquatic environment, and atmospheric environment to assess the overall eco-friendliness in terms of climate change adaptation. The results indicate that an increase in the tree ratio correlates with improved eco-friendliness in terms of thermal, aquatic, and atmospheric environments. In particular, it is necessary to prioritize consideration of the water environment sector in order to realize climate change adaptive green infrastructure, such as increasing green space in urban areas, as it has been confirmed that four out of five target sites are specialized in improving the water environment.

  • Along with response of the Climactic Change Convention, the government is demanding a measuring and reporting system for green-house gas emission and energy consumption on the railroad sector in order to make a transition to a low carbon green railroad system. According to the plans to electric railway line and increase the number of electric rolling stock, the electric consumption is increasing more than the consumption of diesel. Therefore, the development of monitoring device for green-house gases became important issue. In this study we developed a prototype of the monitoring system for estimating electric consumption. This study is expected to make accurate GHG emission inventory and be used to have confidence of emission factor.

  • Since the Kyoto Protocol was released in 2005, there has been a number of mechanisms about funding and how to allocate the burdens. The UNFCCC(United Nations Framework Convention on Climate Change)have discussed establishing an international fund to support the reduction of a greenhouse gas. As the availability of adaption finance for developing countries increase, it's needed for a way of prioritizing countries. This article analyzes the carbon reduction system that includes a emission trading scheme, a carbon tax and examines GCF(Green Climate Fund)'s role and needs. A solution to finance Green Climate Fund is more preferred a harmonized carbon tax that across all nations with carbon tax. Especially the role of industrialized countries is important that based on their historical responsibility for fossil fuel emission. That is, they should get more shares of the global costs than developing countries.

  • Most countries have been focused on the CDM(Clean Development Mechanism). According to Wikipedia, the free encyclopedia, CDM is an arrangement under the Kyoto Protocol allowing industrialized countries with a greenhouse gas reduction commitment to invest in projects that reduce emissions in developing countries as an alternative to more expensive emission reductions in their own countries. There are many environmental problems which resulted from development of IT field. The main objective of this paper is to find an effective methodology as an initial stage for applications of green IT in a real life. Therefore this paper addresses worldwide reviews on green IT products.

  • This experiment was conducted to investigate changes of the components in steamed and roasted green tea after 10 min, 20 min and 30 min of heat treatment of heat treatment at $110^{\circ}C$. Vitamin C and tannin were determined by spetrophotometry. Total nitrogen, water-soluble nitrogen and water-soluble non protein nitrogen were determined by Kjeldahl analysis system. Aromas were identified by gas chromatography. After heat treatment, contents of most compounds decreased. Tannin and caffeine decreased a little bit, while vitamin C decreased considerably. There were both decreases and increases in aromas. Aromas which increased were geraniol, trans-2-hexenol, linalool, $\alpha$-ionone and $\beta$-ionone. From these results, it was concluded that the highest quality of green tea was one steam- treated for 10 min at $110^{\circ}C$.

  • Recently the government banners green growth promises as a paradigm of national development which are to reduce greenhouse gases and environmental pollution by exhaust gases from automobiles. Existing in all countries around the world by using fossil fuels to minimize environmental changes are developing a new alternative energy sources. Among the emerging alternative energy, using solar energy technology is applied across the industry, but the maintenance and repair to integrate solar cells and has been a problem occurs. To prolong the life of cells integrated on a solar cell is exposed when the non-eye, etc., when not integrated by the solar cells should not be exposed. In order to resolve these contradictions, a intellectual solar green street lighting was developed by using Q(Quick)-TRIZ.

  • Recently environmental regulations like the Kyoto Protocol, adopted in 1997, required the reduction of the greenhouse gas of 5.2% up to 1990's emissions and 13th General Assembly in 2007, held in Bali of India, have agreed to duty reduction even in developing countries in 2013. Korean government needs research on climate change and greenhouse gas management, such as carbon emissions calculation system and the introduction of greenhouse gas reduction program. Using Top-Down approach with method of IPCC, greenhouse gas emissions from energy, transportation, agriculture, land use and forest, and waste was calculated. Total amount from Shiheung-City in 2007 was about 3,299.581 tons of greenhouse gas $CO_2$. By sectors, the total greenhouse gas emissions in the energy sector mostly accounted for 78 percent, 12 percent from transportation, 6 percent of waste, the landuse/forest sector, 4% of the greenhouse gas emissions. Approximately 5,401,618 tons of the greenhouse gas $CO_2$ was total amount from Ansan-City in 2007. The share of energy sector greenhouse gas emissions was the highest portion of 79 % and 14 percent of transportation, 4% from the waste sector, 3 % from landuse/forest sector.

  • Climate change is one of the broadest and the most complex issues of international environmental cooperation. Concern about climate change has been steadily increasing and has become a worldwide issue. According to IPCC(Intergovernmental Panel for Climate Change)'s recently report, global warming has accelerated vest serious problems. GHG(Green House Gas) emissions trading schemes, including the Kyoto mechanism that spread to solving the problems. Based on the evaluation on GHG emissions trading schemes, we also find some policy implications on the future development of emissions trading the conventional air pollutants in Korea which start to 2007. The regulatory authority needs to make clear how to allocate allowances to new entrants and also to keep the balance between the opportunity costs of reduction between potential shutdown facilities and new entrants. Under the current rule that does not allow shutdown credits, an equivalent level of allowances needs to be allocated to new entrants free of charge. We believe our policy recommendations may be useful not only for Korea but also for a the other countries, since they are facing a similar policy environment as Korea, particularly in the case of climate change.

  • Carbon dioxide ($CO_2$) is a green-house gas which causes the global warming problems. Anthropogenic emissionspredominantly from the combustion of coal, oil, and natural gas in electricity generations are expected to increase continuously in the future, resulting in increased $CO_2$ concentration in the atmosphere. In this study, we investigated materials properties and process systems for $CO_2$ separation with an emphasis of the post-combustion process.
