Adopting common standards like unique identifiers, labels, and data exchange could improve interoperability between stakeholders in last mile delivery. This would provide benefits like lower costs, reduced environmental impact, and improved customer service. The presentation outlines opportunities for common standards in areas like parcel identification, data capture and sharing, and logistics labeling. Case studies show examples where common standards networks have significantly reduced costs and carbon emissions for last mile delivery.
