| At the 24th Conference of the Parties (COP) detailed implementation of the transparency system under the Paris Agreement was established. Accordingly, the United Nations Framework Convention on Climate Change change (UNFCCC) national greenhouse gas statistics calculation method from 1996 IPCC G/L to 2006 IPCC G/L, and from 2024, Korea also needs to report the inventory applied with 2006 IPCC G/L. Following entry into the Paris Agreement, Korea established an implementation plan to lay the groundwork for early application of the 2006 IPCC G/L. According to the National Greenhouse Gas Statistics Management Plan (Cooperation of related agencies, 2020) the first plan (2015 ~ 2020) included improving the reliability of the national greenhouse gas inventory system and characterizing domestic emissions by expanding the national emission coefficient as well as preparing for application. The second plan (2020 ~ 2024) included expanding the scope of statistics on greenhouse gas emissions and improving the method of statistics calculation. According to Article 25 of the Enforcement Decree of the Framework Act on Low Carbon, Green Growth, the goal was to reduce total national greenhouse gas emissions based on 2017 data by 24.4%. Of the total greenhouse gas emissions of 709.1 million tons of CO2eq in 2017, 173 million tons of CO2eq should thus eliminated. As of 2017, Korea's energy sector's greenhouse gas emissions amounted to 615.8 million tons of CO2eq, up 156% from approximately 240.4 million tons of CO2eq in 1990. Greenhouse gas emissions from the energy sector accounted for 86.8% of Korea's greenhouse gas emissions in 2017. In order to apply the 2006 IPCC G/L to the domestic energy sector inventory, all energy sources must be considered. Among sources not previously quantified, by-product gases (Coke Oven Gas, blast furnace gas, linze donawitz gas) are generated from steel production and are recycled as energy sources in power generation and processes. In this study, the carbon emission factor for coke oven gas (COG), which was not included in the current national energy balance for the 2006 IPCC G/L, was calculated and compared with the IPCC default emission factor to confirm the necessity of developing the carbon emission factor. In addition, the uncertainty was calculated to confirm the reliability of the carbon emission factor. | |
