• Global problems require global solutions – so said Carlos Tavares, the 50-year-old, French-educated Portuguese gentleman in charge of product strategy at Japanese motor firm Nissan, during a speech made in the US last week. You can see where he gets his perspective. “Looking upon planet Earth, you see its characteristic colour is in fact blue,” he said, helping to explain the otherwise puzzling existence of environmental automotive brands like VW’s BlueMotion, Hyundai’s i-Blue, Mercedes’ Blue Hybrid, and Peugout’s Blue Lion. “‘Blue citizenship’ is Nissan’s commitment to the planet,” added Tavares. “Blue citizenship should be our goal rather than green cars.”
