Sustainable Finance has become an important phenomenon in financial markets but is still a new field. That means, there are new things happening every day. It is important to keep innovating in this field, and to critically evaluate what is going on. In this podcast, Julian Kölbel discusses ideas in sustainable finance. New ideas, good ideas, even dangerous ideas. He invites guests who are doing something novel, something interesting, something different that is worth discussing. His goal is to learn from them, to connect their ideas to academic insights, and contribute to the future development of the field of sustainable finance. Julian Kölbel works as an Assistant Professor in Sustainable Finance at the Center for Financial Services Innovation at the University of St.Gallen (FSI-HSG). https://www.unisg.ch/ https://fsi.unisg.ch/
