Retailers play an essential role in shaping product decisions via their own business choices—choices regarding which suppliers to work with, what items to stock, how to manage supply-chain operations, what information to provide to consumers, as well as how their own brand identity and market positioning will relate to sustainability. Retailers thus occupy a unique position in the product value chain, being intermediaries between producers and consumers, with considerable influence on which goods we enjoy as consumers, the means by which they come to us and the long chain of impacts related to our purchasing decisions.
