On a recent episode of The Responsible Edge, host Charlie Martin sat down with Lauren Wilkinson, a sustainability professional with experience at a leading global drinks brand and a recently completed master’s in Energy, Society and Sustainability at the University of Edinburgh.

Through her experience, Lauren uncovered a hidden weakness in corporate sustainability strategies — the environmental blind spot created by marketing supply chains. From branded bar mats to pop-up displays and giveaway merchandise, these materials often escape sustainability oversight, despite being produced at scale.
