Going green has been a major initiative in companies including Whole Foods, IBM and Walmart. However, this initiative is not limited to larger or more successful companies who can afford to make large investments. Initiatives that increase awareness such as eco-driver training and campaigns like “Switch Off” can save 5% and 20% on fuel and energy costs respectively. Therefore revamping or making simple improvements to one supply chain can have significant impacts. It can also lead to serious cost savings which is a key element for companies in today’s economy. Other reasons companies choose to have green supply chains include to achieve regulatory compliance, to fulfill customer requirements, to improve the company's image, etc .
Despite the strong reasoning to do so, the U.S. is lagging behind globally in terms of possessing companies who have the largest environmental footprint. IBM was the only U.S. company to appear in a 2012 Newsweek ranking of the top 10 greenest global companies. With profit and the environment becoming intertwined components, it is not logical for more companies in the U.S. to not do even more to improve their environmental footprint, including greening their supply chains.
