Tractor and semi-trailer transportation's effect on the reduction of CO2 emission in China

Tractor and semi-trailer (T&St) transportation is helpful to promote productivity of freight transportation and to reduce CO
₂
(carbon dioxide) emission according to different countries' experience. The supervisors of China have released certain policies to encourage the development of T&St transportation, while logistics enterprises and academia haven't adapted timely to practice. It is analyzed in this paper some basic characters of T&St transportation. The practice periods of T&St transportation in China have been reviewed and the most necessary issues of T&St transportation are brought forward. A descriptive model has been set up to analyze the relationship between economic profits and CO
₂
emission of T&St transportation. It is found out that T&St transportation could generate considerable economic benefits and effects on CO
₂
emission reduction.
