초록

The number of electric vehicles (EVs) in Seoul has been increasing rapidly since 2017, reducing greenhouse gas (GHG) emissions compared to conventional fuel vehicles. However, the current GHG inventory in Seoul does not accurately reflect emissions from EVs, as they are erroneously categorized under the building sector instead of under transportation. Although the emissions from EVs are not significant, their expected growth necessitates proper classification within GHG inventories. Without adequately calculating emissions by sector, it becomes challenging to establish and analyze local GHG reduction policies. To address this issue, this study was conducted in Seoul's 25 districts to determine the amount of charging required for electric vehicles. The study then trialed two different approaches to calculate GHG emissions. Gangnam-gu had the highest amount of emissions in both calculation methods. However, Geumcheon-gu and Yangcheon-gu had much higher emissions when geographical boundaries of charging were used. In order to accurately calculate EVs emissions based on VKT (Vehicle Kilometers Traveled), clear guidelines for the calculation of HEVs (Hybrid Electric Vehicles) emissions are required. This study recommends measures to enhance the precision of the GHG inventory, ensuring that emissions from EVs are appropriately accounted for within the transportation sector.
