  • 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.

  • PURPOSES: To analyze the specific factors of drivers behaviors that amount of cause the greenhouse gas emissions per vehicle. METHODS: Drivers behaviors at intersections are analyzed on the conditions of acceleration and deceleration. RESULTS : First, it is resulted greenhouse gas emissions per vehicle is produced more at intersections than at the main lines of highway. Second, it is resulted that the average speed, the average acceleration rate and the maximum speed are three major factors to produce greenhouse gas per vehicle in acceleration sections. Third, it is resulted that rapid deceleration 20m before entering intersections is the major factor to produce greenhouse gas per vehicle in deceleration sections. CONCLUSIONS: At intersections, sudden acceleration and deceleration is not good for greenhouse gas emissions. Thus, and the average speed, the average acceleration rate and the maximum speed are the chosen as factors to be controlled for drivers' behavior to reduce vehicles' greenhouse gas at intersections.

  • The purpose of this study is to propose a methodology for estimating greenhouse gas emission reduction through HFCs used in the foam industry. This study investigated characteristics of HFCs and greenhouse gas emissions from production processes in the foam industry, which uses HFCs as a blowing agent. Also, we investigated fluorinated gas removal technology to determine a proper technology for the foam industry. And we confirmed the criteria and characteristics of External Project for methodology development. According to criteria of External Project and foam industrial process emission, a methodology for calculating the amount of greenhouse gas emission reduction in foam industry was developed. Lastly, we analyzed the amount of greenhouse gas emission reduction and KOC (Korea Of Offset) in the foam industry based on the domestic government's plan to reduce HCFCs and imported amount of HFCs used as a blowing agent. The results of this study demonstrate that linking greenhouse gas reduction in the foam industry and the domestic greenhouse gas reduction system can contribute to achieve the domestic greenhouse gas reduction goal.

  • Republic of Korea announced the reduction target to be around 30% of business as usual greenhouse gas emissions by 2020. College campuses were ranked at the 5th of high energy consumption areas in the building sectors. Target management scheme was designed to set greenhouse gas emissions target including several college campuses. Previous studies showed the amount of greenhouse gas emissions with several assumptions such as the applications of renewable energy systems and light emitting diode lamps, etc. Long-range Energy Alternatives Planning model was utilized to simulate future greenhouse gas emissions. This study sets standard model labs for energy saving action programs by applying guidance studies. It has been deduced that energy saving action programs was responsible for reducing 949.5 kWh for each standard model lab and the total reduction of all 59 model labs in the Engineering College building has been calculated to 56,020.5 kWh. The objective of the study is to provide guidelines on standard model laboratory for greenhouse gas emissions reduction on the campus.

  • In this study, the researchers have developed the greenhouse gas emission coefficients targeted at sewage sludge incineration plants that treat sewage sludge by incineration. Among the gases emitted from the sewage sludge incineration plants, the greenhouse gases showed concentrations of 6.84% for $CO_2$, 4.51 ppm for $CH_4$, and 86.34 ppm for $N_2O$; calculated into greenhouse gas emission coefficients, these gave $276.06kg\;CO_2/ton$, $0.0066kg\;CH_4/ton$, and $0.35kg\;N_2O/ton$. As the result of calculating the greenhouse gas emission quantity in sewage sludge incineration plants using the greenhouse gas emission coefficients, the gross greenhouse gas emission was $84.63ton\;CO_2\;eq./day$, and the net emission was $23.90ton\;CO_2\;eq./day$; this was $37.52ton\;CO_2\;eq./day$ less than the net greenhouse gas emission that was calculated using the standard values of IPCC, which was $61.42ton\;CO_2\;eq./day$. This difference is probably because unlike the standard values of IPCC, the greenhouse gas emission coefficients of this study reflected the special properties of subject facilities. Thus, it is thought that emission coefficient research on the facilities that deviated from the standard values of IPCC should continue to achieve the development of national greenhouse gas coefficient that reflects the special properties of Korea.

  • With the signing of the Paris Agreement, an accord concerning the post-2020 climate change regime, in December 2015, all nations around the globe recognized the problem of climate crisis and are proactively reducing the emission of greenhouse gases. The South Korean government has announced plans to reduce the country's greenhouse gas emissions by 37% from the business-as-usual level of 850.6 million tons of carbon dioxide equivalent (Mton CO2e). The plans have set a target of 32.7% minimization for the building sector, which is expected to have a high reduction potential. This study aims to forecast the greenhouse gas emissions in Korea's building sector after 2020 based on its current state of emissions. This study proposes a statistical predictive modeling approach to discover the greenhouse gas emissions projection in building sector by 2030 using regression analysis models, time series models, growth curve model. To this end, the Bass model was applied as the optimal forecasting model as it is assessed to have high predictability. According to the Bass model's predictions of greenhouse gas emissions in the building sector, the level is expected to increase from 156.8 Mton CO2e in 2020 to 173.3 Mton CO2e in 2025, and eventually to 189.0 Mton CO2e in 2030. Compared to the nationwide greenhouse gas emissions forecast, these predictions are higher by approximately 9.8% to 12%. Considering the lack of research on the prospects of domestic greenhouse gas emissions, this study is meaningful as it provides significant results that are necessary for analyzing potential reductions in greenhouse gas emissions and establishing measures for their cutback. Additional research is required on forecasting long-term greenhouse gas emissions through the establishment of optimization models.

  • This study has conducted greenhouse gas emission reduction test as using Oyster-shells originated PCC paper filler compare to non-Oyster shells used PCC. This examination was estimated and calculated in accordance with both IPCC (Intergovernmental Panel on Climate Change) and World Business Council for Sustainable Development (WBSCD). The greenhouse gas emission reduction estimation result indicates that, when oyster shells are recycled and used as paper filler, it reduces $27.97tCO_2\;per\;100\;ton$ of oyster shells. It is greenhouse gas emission $44.27tCO_2$ from PCC production changed to carbon emission reduction when replaced with oyster shell. LNG greenhouse gas emission $16.3tCO_2$ in relation to the pre-treatment with oyster shell per 100 ton is also reflected. As a result, it is assumed that roughly $0.2797tCO_2/oyster\;shell{\cdot}ton$.
