The purpose of this guide is to provide an overview of the importance of traceability for sustainability purposes, outline the global op- portunities and challenges it represents and summarize practical steps for implementing traceability programmes within companies. Research for this guide revealed that trace- ability is a tremendously impactful tool for advancing sustainability objectives, but it still has a long way to go before it is an integral part of sustainable supply chain management and is used widely by companies. At present, only a very small percentage of commodities are traceable on sustainability attributes.
