Taking into account the serious greenhouse effect of the earth, drastic proposal which prevents the carbon dioxide emission from transportation system must be done. In Japan, over 20 percent of the carbon dioxide are emitted from transportation. Aero-train is the new zero-emission high speed vehicle, which is being proposed. Wing in ground effect is introduced to obtain highest lift to drag ratio and highest payload ratio. In order to compare the performance of the aero-train at 500 km/h, with several other traffic systems, eco parameter is newly created as E(sub c) = (L/D)(W/W(sub o))(V/500)(exp 2) and compared. Eco parameter of the aero-train was over six and showed the highest value among them. Because of such high energy efficiency, this system can run using only natural energy existing in the guideway area of the aero-train system. Namely, aero-train is the zero-emission vehicle.
