Abstract

Due to its rapid economic and population growth, Northeast Asia has emerged as the most emitting region in the world, contributing significantly to global air pollution. To address this issue, our study aimed to develop and enhance the emission inventory for Northeast Asia, building upon the Comprehensive Regional Emissions inventory for Atmospheric Transport Experiment (CREATE) framework previously developed. The primary objective of this research was to provide a comprehensive and up-to-date emission inventory for the region, which plays a crucial role in understanding air pollution processes and forming effective policy directions. To achieve this, we integrated the existing CREATE emission framework with the latest information on activities, emission factors, atmospheric policies, and reduction efficiencies specific to Northeast Asia. For activity data, we utilized official national data from Korea and the most recent energy statistical data provided by international organizations. Our focus was on eight significant air pollutants: CO, SO2, NOx, NMVOC, NH3, PM2.5, and PM10. The developed inventory is designed to be efficiently integrated with air quality model processing systems like SMOKE, KU-EPS, and others, facilitating further analysis and research in this critical area. This new CREATE inventory has been used to compile project-based regional emission inventories, such as KORUS-AQ, LTP, and SIJAQ. In this presentation, we will present the enhancements made to the CREATE emissions framework and present the outcomes of the emissions achieved through the updated inventory.
