With　the　development　of　economy,　the　service　industry　has　become　a　new　field　of　energy　saving　and　emission　reduction　needed　to　explore.　As　the　most　major　component　of　service　industry,　the　energy　saving　and　emission　in　transportation　industry　are　paid　more　and　more　attention.　The　carbon　emission　in　Beijing　from　2005　to　2012　is　accounted　in　this　paper.　With　2005　as　the　baseline　year,　the　complete　decomposition　method　is　used　to　analyze　Beijing＇s　transportation　energy　consumption　and　carbon　emission.　The　conclusions　are　as　follows:　The　overall　transportation　energy　consumption　and　carbon　emission　show　an　upward　trend　in　Beijing,　and　scale　factor　and　energy　consumption　intensity　factor　are　playing　the　catalytic　role　in　transportation　energy　consumption　and　carbon　emission.　Among　them,　the　industrial　scale　factor　plays　a　major　role　on　the　growth　of　carbon　emission　in　transportation　industry.　Energy　consumption　structure　factor　plays　a　smaller　role　on　carbon　emission　in　transportation　industry,　and　it　almost　has　no　effect　on　energy　consumption.　This　paper　also　proposes　recommendations　for　future　low-carbon　development　in　Beijing　transportation　industry.
