Who produces the most CO2 emissions for trips in the Seoul metropolis area?

This study identifies the largest producers of CO₂ emissions in the Seoul metropolis area, focusing on land-based passenger transportation activities as revealed by the 2006 household travel diary survey. Combining modal CO₂ intensities and travel distances, the amount of daily individual CO₂ emissions is estimated. The cumulative distribution of the CO₂ emissions revealed that the top 10% emitters in Seoul, who produce daily about 4.5kg of CO₂, were responsible for 63% of transportation's emissions. CO₂ emissions are found to be strongly associated with emitters' socioeconomic characteristics, with adult males being the largest emitters producing about 3.9kg of CO₂ daily.
