自動車CO₂ 排出量の視点からみた都市集約化のあり方に関する研究

−都市特性の違いに着目して−

This study used multiple regression analysis to examine critical factors of urban characteristics affecting CO₂ emissions from automobiles. Its results suggest effective compaction of urban structures to reduce CO₂ emissions. Findings indicate that (1) the relation between urban characteristics and CO₂ emissions is stronger for larger populations. Moreover, (2) CO₂ emission reductive effects were identified by increasing populations around stations in cities in three major metropolitan areas and around schools in cities outside of three major metropolitan areas.
