Abstract

This study analyzes the factor decomposition of greenhouse gas(GHG) emissions in the domestic paper industry of Republic of Korea using the log mean Divisia index (LMDI) method. Five factors were decomposed: active effect, structural effect, intensity effect, energy mix effect, and emission increase/decrease effect(total effect). Analyzing GHG emissions by paper type from 2010 to 2021, the study finds that emissions from the domestic paper industry have been decreasing since 2010, with the major factors for this decrease being structural and intensity effects. The structural effect is the most significant factor in reducing GHG emissions, representing approximately twice the impact of the intensity effect. The active and intensity effects appear differently depending on paper type. Even though the active effect increases GHG emissions, the total GHG emissions decrease due to the intensity and energy mix effects. Therefore, to reduce GHG emissions in the paper industry, it is necessary to focus on the structural and intensity effects; however, differences exist depending on paper type. Furthermore, expanding support for decarbonization policies not only from companies but also from governments is essential.
