Wal-Mart and Interface collaborated on sustainability initiatives, with Interface mentoring Wal-Mart. Interface transformed itself from a carpet manufacturer into a sustainability leader after its CEO had an epiphany about the environmental impacts of industry. Interface advised Wal-Mart and helped shift its culture towards sustainability. In 2005, Wal-Mart's CEO announced ambitious sustainability goals to be powered by renewable energy and produce zero waste, looking to Interface for guidance on this transformation.
