Read an article several years back in Machine Design magazine about a study done on the environmental cost of a Hummer, and a Prius. Seems the Hummer might use more fuel than a Prius but it's actual environmental impact (cost to the environment) was less than the Prius by a large amount. Basically the Hummer uses easily recyclible materials, used alot of off the shelf technology that didn't require the effort and expense of teams of engineers to design, no special handling of the recycliables (like the Prius batteries, etc), etc, etc, etc. Ultimately the Hummer's total cost to the environment from conception to scrap yard was about half of the cost of the Prius. Now if you wanted to be really environmentally friendly one of the old, origional, VW bugs was way below either of the others listed.
True or not I don't know, but when you think about the facts stated they really make sense. Too, they did tell who did the study, etc so it would have been fairely easy to look it up and read the whole thing.
