The word ‘Green’ is being overused and isn’t very specific, but it’s a widely used adjective seeming to mean cleaner ways or products. This web site is about exploring the intersection of “Green” and “Transportation” but goes beyond simply cleaner ways to transport ourselves around.
A better phrase than ‘Green Transportation’ would be ‘Sustainable Transportation’. The word ‘Sustainable’ clearly means activities that support the long term livelihood of our society.
The negative effects of our transportation system is large and the “greening” of the transportation system is very important. Unfortunately “Green such-and-so” is widely used in many areas, without a precise meaning. That leaves us lacking precision for “Green Transportation”. Even the phrase Sustainable Transportation is not very clear. Basically, sustainable means something that can survive for a very very long time. For example sustainable farming practices would produce food for several generations without applying external inputs like fertilizers.
