Retailers have often been perceived as not only playing a passive role in sustainability, but in some cases being part of the problem. According to UNEP the world's 200 largest retailers account for 30% of worldwide demand. Therefore, actions by retailers have a significant effect in this area, and in many cases, retailers are actually leading the charges. One example is Wal-Mart, whose website states, ' With roughly 61,000 suppliers, 176 million customers each week and more than 2 million associates, we have the ability to reach and influence people on a level unattainable by are other company'. Their strategy, known as Sustainability 360, includes goals and targets in their supply chain, in the products they sell, their employees and the communities they operate in and source from. Wal-Mart aims to be supplied by 100% renewable energy, to create zero waste, and to sell products that sustain our resources and the environment.
