Creating a green business has become a rallying cry heard by many supply chains over the past few years. However, As David Blanchard of Industry Week points out, not every U.S. Manufacturer believes going green is really going to help their bottom line. However, there are times when going green can save big green as well. For instance, consider the savings Nike achieved by using ocean vessels for shipping: For instance, shipping goods by rail is much more economical for manufacturers than shipping by truck. In some cases, rail transportation uses less fuel and produces fewer GHG emissions than trucks, and substantially less than airplanes. A recent study produced by the Environmental Defense Fund (EDF) points out that if ocean vessels are used as the benchmark, rail produces 1.6 times as much GHG emissions as ships, trucks produce 10 times as much, and planes produce 47 times as much. Apparel producer Nike, for instance, reportedly saved $8 million in annual transportation costs by shifting most of its trans-oceanic cargo from air freight to ocean vessels. Also take into account the savings of Colgate-Palmolive, Co., which created an intermodal strategy to move freight via container for as much as possible by train. The overall result was a reported 300,000 gallon fuel reduction in its transportation supply chain.
