Honda: Honda H2O

A wall-sized, 1966 quote from Soichiro Honda greets visitors to Honda's head office saying, "Leave blue skies for our children". This commitment to a cleaner future led Honda to develop the world's first mass production car that runs only on hydrogen - the Honda FCX, so the only emission from its exhaust is water. Water so pure and clean, you could put it in a bottle and drink it.

To demonstrate just how clean Honda's hydrogen fuel technology is, Honda Australia and Leo Burnett Melbourne decided to put it into the hands (and mouths) of the audience, launching H2O - the first water brand created by a car company. Agency: Leo Burnett, Melbourne.
