Abstract：Research purposes: Highway tunnel needs consumption of a large number of energy，the China＇s transport authorities focus on its energy － saving and emission reduction． Research shows that there are still many deep － rooted problems in the energy － saving and emission reduction of highway tunnel while making some progresses． On the basis of analyzing factors that effects the energy － saving and emission reduction of highway tunnel，the countermeasures for energy － saving and emission reduction of highway tunnel are proposes from the systematic engineering angle for providing the reference to the further energy － saving and emission reduction of highway tunnel．
Research conclusions: At present，the problems in the energy － saving and emission reduction of highway tunnel in China mainly relate to the balance of economic and social benefits，wide application of the of energy － saving products and technology，standardization of the statistical index system for energy － saving，special fund for energy － saving and emission reduction and the supported of the relevant policies and regulations． The factors that affect the energy － saving and emission reduction include civil engineering structures，mechanical and electrical facilities，traffic characteristics， economic capacity and natural conditions． The countermeasures for the energy － saving and emission reduction of highway tunnel include the energy － saving by the structure，the energy － saving by technology and the energy － saving by management．
