“…To assess and quantify the air pollutant emissions, GHG emissions are calculated by introducing the emission factors of fossil-fueled power plants (coal, natural gas, oil). Many studies have shown that these emission factors are not constant, but there is an underlying variability even for the same type of fossil-fueled power plant [9][10][11]. There are different reasons for this variability.…”

“…The air pollutant emission factors of power plants can be taken from several studies [10,11] and the resources of various organizations such as the emission factor database (IPCC Emission Factor Database, n.d.) provided by the Intergovernmental Panel on Climate Change (IPCC), the Updated Greenhouse Gas and Criteria Air Pollutant Emission Factors of the U.S. Electric Generating Units in 2010 [13], and the Umweltbundesamt (UBA) emission factors.…”

Germany and South Korea are the world's sixth and seventh largest emitters of greenhouse gases, respectively; their main sources of pollution being fossil-fueled power plants. Since both countries signed the Paris Agreement in 2016, renewable energy transition is emerging as an effective means and method for avoiding air pollutant emissions and for replacing old fossil-fueled power plants. This paper attempts to evaluate-by using a grid emission factor dependent on a series of energy mix scenarios-the potential for South Korea and Germany to reduce their air pollutants (CO 2 , NO x , SO x , PM (particulate matter)) until 2030. South Korea plans to reduce greenhouse gas emissions by increasing nuclear power, while Germany aims to do so by shutting down its nuclear power plants and expanding the proportion of renewable energy in the energy mix to over 50%. Therefore, both countries are able to achieve their voluntary greenhouse gas reduction targets in the power sector. However, since the uncertainty of the CO 2 emission factor of coal power plants in South Korea is as high as 10%, efforts to reduce that uncertainty are required in order to produce a reliable assessment of the avoided emissions.

“…The fourth and fifth stages calculate the emission factor per 1 ton of fuel by dividing the carbon emission from the third stage from activity (fuel usage) and multiplies 44/12 to calculate the CO 2 emission factor. Here, the CO 2 emission from the Korean coal briquette may be calculated by multiplying annual briquette consumption and the oxidation rate using the CO 2 emission factor of the briquette from above (Jeon et al, 2010).…”

Korea adheres to the basic emission factor proposed by the Intergovernmental Panel on Climate Change Guidelines to calculate the greenhouse gas emission. However, the Intergovernmental Panel on Climate Change Guidelines recommends applying an emission factor unique to a country, which reflects its features in fuel consumption. Especially, there has been little research in emission factors and in the amount of Korean coal briquettes used in Korea, and even worse, the Intergovernmental Panel on Climate Change Guidelines has not proposed the basic emission factor for such briquettes. Recently, the Korean government has made efforts to calculate greenhouse gas emission factors for each sector, and it is requiring research and development be conducted in the greenhouse gas emission factors of Korean coal briquettes in household and commercial sectors. The amount of carbon, hydrogen, and calorific values in the input fuel was measured using a calorimeter, elemental analyzer and proximate analyzer. For fuel analysis, the CO 2 emission factor for Korean coal briquettes is 95,558 CO 2 Kg/TJ. It is lower than the local anthracite CO 2 emission factor, 111,100 CO 2 Kg/TJ and the 2006 IPCC Guidelines, 87,399 CO 2 Kg/TJ by about 13.99 and 2.79%, respectively.

“…For ordinary combustion facilities, particularly for a largescale combustion facility like power plants, the combustion process is designed and managed in such a way as to maximize the oxidation ratio of carbon, fuel energy source, since efficiency will improve only if the maximized energy is utilized. In the fourth stage, carbon emissions were to be multiplied by 44/12 and divided by activity (energy input and fuel consumption) to assess CO 2 emission factors depending on the activity (Jeon et al, 2010). …”

Greenhouse gas emissions of the nation should be precisely assessed in order to effectively tackle the problems stemming from climate changes. To do so, country-specific data that reflect a nation's distinct characteristics must be applied to more precisely assess greenhouse gas emissions. In this research, carbon emission factors were assessed for emission sources making up over 53% of the domestic anthracite consumption with calorific values of fuels and elementary analysis. Furthermore, oxidation rates were assessed based on measurement results of unburned carbon produced from tested power plants to calculate CO 2 emission factors. Ultimately, the CO 2 emission factor was calculated at 106,747 kg/TJ, about 9% higher than the anthracite emission factor presented by the Intergovernmental Panel on Climate Control. Such differences are assumed to mainly come from disparities of anthracite properties along with combustion technology and differences of oxidation rates depending on the combustion conditions. Therefore, continued research on a wide variety of fuels and energy consumption facilities should be conducted in order to establish countryspecific data, which will help more accurately assess greenhouse gas emissions and subsequently will lead to reliable greenhouse gas reduction goals.
