We had this at my works last year - I did the official photo's - its was basically a load of b******s!
Just an excuse for your company to say how envnro friendly it is which is pretty damn hard for mine as it manufactures assorted chemical products for house and home etc!!
Of course local toyota dealer got on the act and they had a Prius and Lexus doodar on show at the front of the building - talk about sales opportunity or what! Don't beleive the hype most companies just use it as a PR exercise as does the government!
Defence rests your honour!
