According to the U.S. Department of Energy, manufacturing and transportation account for 61 percent of energy consumption in the United States. Supply chains therefore are a key driver of carbon emissions and are poised to play a critical role in achieving any United Nations or local reduction targets. Participants will get a framework to help them identify sources of carbon throughout their supply chains along with recommendations on how to manage this new and intriguing decision variable. Tradeoffs between "classic" operational metrics, such as cost, inventory turnover, and carbon reduction, will be explored and analyzed. Following the presentation, participants will have a better understanding of sources of carbon in their supply chain, gain a better understanding of how to model carbon as a new operational decision variable, and get a clear picture on how to proceed in "greening" a supply chain.
