Together with Christian Heuss, Prof. Janina Grabs, a sustainability researcher at the University of Basel, talks about how global value chains for coffee, cocoa and palm oil can become more socially just and environmentally responsible. She explains why voluntary certification schemes are insufficient on their own, how emerging due diligence legislation can shift power structures along supply chains, and which practical challenges producers face in meeting new standards. She also reflects on the responsibilities of companies, governments and consumers in ensuring that sustainability efforts lead to real impact rather than symbolic compliance.
