Abstract

In this study has been attempted to investigate energy efficiency in transportation sector by using an index decomposition analysis approach IDA and LMDI method. In this method, at first analysis the Changes of energy consumption to it's effects and then by using intensity effect savings from improving efficiency is specified, then checked efficiency trend using energy performance index. Transportation sector due to use of the physical measurement indexes are divided to two subsectors: goods transport sector and passenger transport sector. Results in passenger transport sector, shows lack of efficiency in this sector. Only in 2007, improving efficiency causes to positive savings in this sector.  In goods transport sector, despite of passenger transport in most years except for 2005 and 2008, efficiency has been increased and savings from increased efficiency has been positive.
