Abstract

This paper introduces the emission status and the mitigation technologies of non-CO2 greenhouse gas (GHG) in Korea. The total emission of GHG is 695 million ton CO2–eq at 2013. About 10 % of them are non-CO2GHGincluding HFCs, SF6, N2O and CH4 which mostly come from energy conversion plant, semiconductor and chemical industry, organic waste treatment facilities. Korean government has finalized its 2030 target of reducing GHG emissions by 37 percent from business-as-usual (BAU) levels of 851 million tons. Above 315 million ton CO2-eq has to be reduced to meet the target. The government has come up with a number of complementary measures in order to successfully implement its plan including an emission trading system. Several non-CO2 GHG mitigation projects from industrial facilities have been already executed by international project base such as CDM utilizing the direct incineration or decomposing technologies at high temperature. Although these incineration technologies are simple for installation and maintenance, the additional CO2 emission to atmosphere cannot be avoided due to CO2productionduring incineration and high energy consumption. The thermal energy consumption to raise the flue gas temperature is large because the non-CO2 GHG concentration from industrial facilities is very low. The various leading technologies are under development to lower the energy consumption for decomposing the non-CO2 GHG or conversion these to the useful by-products.
