Abstract
This study analyzed the greenhouse gas (GHG) emissions from the transportation sector in Korea from 1990 to 2013 using Logarithmic Mean Divisia Index (LMDI) factor decomposition methods. We decomposed these emissions into six factors: The population effect, the economic growth effect due to changes in the gross domestic product per capita, the energy intensity effect due to changes in energy consumption per gross domestic product, the transportation mode effect, the energy mix effect, and the emission factor effect. The results show that some factors can cause an increase in GHG emissions predominantly influenced by the economic growth effect, followed by the population growth effect. By contrast, others can cause a decrease in GHG emissions, predominantly via the energy intensity effect. Even though the transportation mode effect has contributed to a reduction of GHG emissions, it remains relatively small compared to other factors. The energy mix and emission factor effects contributed to the reduction of GHG emissions in the early 2000s, however the effects have led to an increase of GHG emissions since the mid-2000s. Altogether, based on these results, this study suggests some GHG mitigation policies aimed at achieving the national target for this sector.
Highlights
Transportation is one of the major sectors that emit greenhouse gas (GHG)
The results yielded for each year represent the values of the individual effects of the impact factors used for the decomposition analysis of the increase in GHG emissions from 1990 to that year
The year 2000 results showed that GHG emissions during 1990–2000 increased by 29,306 Gg due to the economic growth effect, 4665 Gg due to the population effect, 1412 Gg due to the energy intensity effect, and 32 Gg due to the emission factor effect, and reduced 145 Gg due to the transportation mode effect and 139 Gg due to the energy mix effect
Summary
Transportation is one of the major sectors that emit greenhouse gas (GHG). World GHG emissions from transportation sector accounted for one quarter of total emissions in 2016, a 71% increase compared to 1990. Most of the transportation sector’s GHG emissions result from fossil-fuel combustion. In 2013, Korea’s GHG emissions from the transportation sector accounted for 12.6% of total emissions—below the world average. Their growth rate is higher than those from the industrial or power sectors. This high growth rate is due to an increase in vehicle use due to economic growth
