The purpose of this paper is to examine the effect of urban spatial structure on transport sector CO2 emission using system dynamics simulation method and to find policy implication for urban planning. For this purpose, system dynamics model containing two competing arguments on the impact of high density development on air pollutant emission from transportation was built and simulated for four selected case cities representing different types of urban spatial structure; high density-monocentric city, high density- polycentric city, low density-monocentric city, and low density-polycentric city. Simulation results show that increasing both development density and mixed land use decrease number of car users, increase number of public transportation users, and decrease total CO2 emission from transport sector. And cities with higher density show higher CO2 reduction result in transportation sector than cities with lower density. In addition, high density-monocentric city shows better CO2 reduction rate than high density-polycentric city, indicating that monocentric compact city is better in reducing CO2 emission from transport sector.
