Scott-Wicker-UPS.jpg With nearly 100,000 ground vehicles globally, and operating as the ninth largest airline in the world, UPS has an expansive fleet that is both logistically incredible and, as it turns out, increasingly green. Scott Wicker, UPS’ Chief Sustainability Officer, is on a mission to make both the ground and air fleets more efficient and environmentally friendly. UPS views its fleet as a “rolling laboratory” to test out the latest energy-saving technologies, alternative fuels and logistical eco-improvements.
