　　This study applies the LMDI decomposition analysis approach to identify the key factors which affect greenhouse gases (GHGs) emission from Taiwan’s road transportation sector during the period of 1995-2005. The results indicate that per capita energy consumption for road transport and the population growth are two primary factors causing its GHGs emission to increase. Popula-tion growth is the secondary primary factor causing GHGs emission to increase, however, along with Taiwan’s decreasing birth rate in recent years the emission increase presents a reducing trend. It is noticeable that the emission increase inducing by per capita energy consumption presents a growing trend due to con-tinuously increasing private transport in Taiwan. It implies that cutting down per capita energy consumption is an important way to reduce GHGs emission from this sector. The promotion of a public transport system, however, is a pivot strategy to reduce the growth of private transport and per capita energy con-sumption for road transport as well. Besides, the development and application of non-fossil energy technologies is the essential way to further cut GHGs emis-sion from Taiwan’s road transportation sector.
