In his keynote, Torsten Jäger of the German Banking Association gave practical insights into how financial institutions can support companies through transformation, even in challenging times.

International perspectives on ESG and pragmatism

After lunch, Prof. Dr Robert Eccles of Harvard University, KKR, Saïd Business School and the University of Oxford connected perspectives from the real economy and academia.

His international perspective on the ESG debate and the need for so-called “Sustainability Pragmatists” provided further food for thought for the subsequent discussions moderated by Prof. Dr Timo Busch of the University of Hamburg.
