Yahoo! this morning has an article on how un-green certain modes of transportation might actually be. We all think mass transit (buses, trains, etc.) are the way to go, rather than the lone driver behind the wheel of their own car. But if those buses and trains are not at capacity, they’re now saying you could be better off driving than in one of those beasts. And we’ve all seen the buses belching smoke from their exhaust. If there are only five people on the bus, is it really a green ride? Apparently not. There’s more that goes into these calculations than simply the number of cars on the road.
A saloon (sedan) car or even an 4×4 that is fully occupied may be responsible for less greenhouse gas per kilometer travelled per person than a suburban train that is a quarter full, the researchers calculate.

You still can’t argue with a bike.

I think mass transit is hyped too much, as a greener way to trave. I work on the railway here in Wales, and see at close hand the amount of pollution they belch out.

I’ve always wondered about that, more so with buses since trains aren’t used much for travel in my area. There’s a reason the exhaust is vented out of the roof of the bus, rather than at ground level like cars.
