sustainability leaders from ups, the hitachi foundation and verizon discussed how their businesses are reducing their carbon footprint while adding green to their revenues at the new green economy conference on january 22 in washington, d.c. ups avoids left hand turns as much as possible to save fuel waiting at intersections and uses advanced routing systems to find the most efficient ways to get from point a to point b while delivering thousands of packages a day. no left hand turns may seem like a random act of greenness, but even simple tasks such as turning off vending machine lights is saving ups thousands of dollars a year. verizon is expanding its broadband and hitachi is using recycled materials for their electronic equipment.
