“…This study used fuel analysis method (Quick and Brill 2002) suggested by IPCC that consists of a five-step worksheet to calculate CO 2 emission factor of bituminous coal, such as (Lee et al, 2013):  Examining the amount of carbon and water, which have the biggest influence on the emission amount of CO 2 . The amount of carbon is changed into the "asr basis" amount at this stage.…”

Climate change will become the priority for the air quality management. It focuses more on carbon dioxide emission. Indonesia which has power generation dominated by coal combustion is expected to develop the national CO2 emission factor. Due to the high variation in Indonesia coal rank and its growing magnitude in CO2 emission caused by the future coal-fired power plant development, the characteristic emission value becomes an important concern. The method used in this study is developed from the IPCC Guidelines for Energy. The conversion unit plays an important role in the calculation method. The result shows that the higher in C content, the lower in its CO2 emission factor. It means that coal classified as high C content or high heating value will produce low carbon dioxide emission factor. The average CO2 emission factor obtained in Indonesian coal is 99,718 kg CO2/TJ with an average value of carbon content 27.2 kg C/GJ, and NCV equal to 19.8 TJ/Gg. Coal rank is categorized as lignite to subbituminous or bituminous.

While the Intergovernmental Panel on Climate Change classifies coal as anthracite, bituminous coal, and sub-bituminous coal, Korea only distinguishes coal as anthracite and bituminous coal while sub-bituminous coal is considered bituminous coal. As a result, Korea conducted research in the CO 2 emission factors of anthracite and bituminous coal, but largely ignored sub-bituminous coal. Therefore, the purpose of this research is to develop the CO 2 emission factor of sub-bituminous coal by classifying sub-bituminous coal from resources of bituminous coal activities collected in Korea between 2007 and 2011. The 2007-2011 average carbon content of sub-bituminous coal was analyzed to be 69.63 ± 3.11 %, the average hydrogen content 4.97 ± 0.37 %, the inherent moisture 12.60 ± 4.33 %, the total moisture 21.91 ± 5.45 %, and the dry-based gross calorific value was analyzed to be 5,914 ± 391 kcal/kg; using these analyzed values, the as-received net calorific value was found to be 20.75 ± 7.59 TJ/Gg and the CO 2 emission factor was found to be 96,241 ± 4,064 kg/TJ. In addition, the 62.7 million ton amount for the 2009 greenhouse gas emission from sub-bituminous coal as estimated with the analyzed value of this study is an amount that is equivalent to 11.1 % of the 2009 total greenhouse gas emission amount of 564.7 million tons, and this amount is larger than the 9.3 % for the industrial processes sector, 3.3 % for the agricultural sector and 2.5 % for the waste sector. Therefore, it is important to reflect the realities of Korea when estimating the greenhouse gas emission from such subbituminous coals.

This study analyzed a change trend of ambient tem perature over the last sixty years in the largest in dustrial city in Korea, Ulsan. Linear warming rates in Ulsan over the last 25 (1985 to 2009), 40 (1970 to 2009), and 60 (1950 to 2009) years were 0.0507, 0.0416, and 0.0277°C/yr, respectively. The annual average temperature (AAT) and the annual average of the daily lowest temperature (AADLT) in Ulsan in creased 1.3 and 2.9°C, respectively, over the last fifty years (1960 to 2009). The increasing slopes of the AAT and AADLT over the fifty years in Ulsan were higher or much higher than those in neighboring cit ies and on a global scale. In the comparison analy sis of daily average temperature over the most re cent ten years, the highest (15.9°C) was observed in the industrial area followed by the downtown, coas tal, suburban, and rural areas with 14.6, 14.5, 14.0, and 12.8°C, respectively. The number of cold days less than 5.0°C decreased, while the number of hot days higher than 20.0°C increased. The decreasing slopes in the cold days in lower latitude cities were steeper than those in higher latitude cities in Korea.
