John and Mike speak with Kory Lundberg, Senior Manager and Head of Sustainability Communications at Walmart. The company is the largest retailer in the U.S., and its three-point sustainability outline that it is working toward is a paramount example for others to follow: Be supplied by 100% renewable energy, create zero waste and sell products that sustain people and resources. “Walmart is about lowering costs and operating more efficiently,” Lundberg says. The company operates highly efficient stores across the world, but is always looking for ways to use less. “When you have 8,400 locations across 15 countries, it really makes an impact. We can share our learnings in the U.S. with our teams around the world.”
