In this episode, Marta and Willem invite a long-time listener and supporter of the Bestek podcast and a postdoctoral fellow at PurpLE, Ezgi Uysal, to discuss her research on the topic of sustainability contractual clauses (SCCs) in public procurement contracts. The podcast begins with Ezgi briefly explaining what the SCCs are and what makes them unique, before quickly diving into a discussion about the contractualization of sustainability in public procurement. The speakers then examine different types of SCCs as well as challenges concerning enforcement. They discuss the potential consequences of the failure of contracting authorities to enforce said obligations. Additionally, the speakers argue in favour of the need for improvements in contract management to deliver sustainable public procurement and communication between the contract-drafting and contract-managing teams and discuss whether these problems could be solved by a legislative intervention. For dessert, Ezgi reflects on her PhD experience and provides some heartfelt advice for the first-year PhD students and beyond.
