value chain vs supply chain

The difference between supply chain and value chain is subtle and is best explained as follows:Supply chain describes the end-to-end production, with customer satisfaction as the key objective.Value chain takes a wider view and is focused on the end-to-end creation and delivery of value, with competitive advantage as the key objective.As the term value chain includes processes and activities that aren’t captured by the term supply chain, it is therefore most appropriate to use in relation to a carbon footprint.
