Optimizing supply chain operations to cost less and be more effective has long been a top priority for businesses. Now, companies must consider new sustainability measures such as carbon. Identifying, tracking and managing supply chain emissions is quickly becoming essential to optimization efforts, with the primary goal of detecting inefficiencies in fuel, electricity and water consumption and then correcting those inefficiencies to help eliminate waste and reduce costs. But improving one benchmark in an optimization effort may adversely impact another. It's rare that everything aligns perfectly.
