	There are many approaches to the solutions of the global warming, and one of the important ones is the Intelligent Transport Systems (ITS). This paper surveys the effects of the ITS technologies on the energy conservation or the global warming. The ITS could contribute to the energy conservation on two aspects: one is to eliminate the congestion, which enables each automobile to drive at the fuel optimal speeds, and the other is to provide means for modal shift, which reduces the traffic. This paper surveys the ITS technologies including traffic signal control, ETC, route guidance, cruise control, automated driving.
