Preparation for the greenhouse gas emission issues in the national defense

다국어 초록 (Multilingual Abstract)

This study reviewed the current readiness levels and future strategies for greenhouse gas emission issues in the military sector of the Republic of Korea (ROK). First, it considered greenhouse gas management policies of foreign and ROK military sectors and analyzed the completeness of the greenhouse gas inventory calculations of the USA, UK, and EU. Although it was not possible to quantitatively analyze the levels of the considered military sector policies and the degree of participation currently underway, it was clear that the military's role in responding to future climate change crises is expanding globally. After that, the study reviewed the research on calculating the greenhouse gas inventory of the ROK military sector and newly calculated the greenhouse gas inventory using its own methodology, including ammunition use and absorption sources creatively. As a result, it was confirmed that approxi-mately 3.45 Mt CO2-eq (0.5% of the total national emissions) greenhouse gases were emitted by the military sector in 2020. Moreover, the net greenhouse gas emissions were calculated to be high in the order of the air force, army (including units under the direct control of the Ministry of Defense), navy, and marine corps. Most of the emission sources were the uses of aircraft and electricity. From the inventory calculation results, to reduce the greenhouse gas emissions of the ROK military sector, it was concluded that it is necessary to change the fuel use, improve the efficiency of military facilities, and improve the utilization rate of new renewable energy.
