Talking Supply Chain: Sustainable procurement moves from optional to essential

In this episode of Talking Supply Chain, host Brian Straight explores the growing importance of sustainable procurement—a practice that has quickly moved from a “nice-to-have” to a business imperative. As governments, investors, and customers increasingly demand accountability, procurement is no longer just about efficiency and cost; it is about building resilience, reducing carbon impact, and delivering long-term value across the supply chain. Brian is joined by Dr. Luan Ho, Science Team Co-Lead at Tunley Environmental, a consultancy helping organizations embed sustainability into their procurement processes. Dr. Ho outlines Tunley’s evolution from an engineering-focused firm into a sustainability leader.
