Motorcycles And Other Vehicles CO2 Emissions

　　As we all know, most forms of transportation emit CO2, and that's a bad thing for our fragile planet. The more CO2, the worst it is. Motorcycles have often been labelled enormous CO2 emitters by the overzealous ecologists. They have never been able to offer real proof, while the opposite is true. Not only do they push less CO2 in the air per kilometer, but since our trips take less time, we therefore emit less CO2.

　　In France there's been a study, and an average per transportation calculated. Here's what it looks like (the 1st column is the grams per kilometer per person):

CO2 g/km pp	Transportation 交通工具
0	Walking, Bicycles 行走/自行车
20	Tram/Train 电车/火车
65	Moped 机动脚踏两用车
80	Bus 公交汽车
85	125 cc motorcycle 125CC摩托车
115	400 cc motorcycle 400CC摩托车
115	Car (unleaded fuel) 汽车（无铅燃料）
133	Car (diesel fuel) 汽车（柴油燃料）
160	Large displacement motorcycle 大排量摩托车
205	SUV
230	Small truck (less than 3.5 tons) diesel小型卡车（小于3.5吨）

　　So with smaller motorcycles, the CO2 is less than any type of normal car, while even the very big motorcycles have less than big cars, and if you take the time your engine is running, less than any car.
