Dr Marcel Jeucken is author of many books on sustainability and finance. The financial sector plays a fundamental role in any society and can be a driving force for a sustainable development of the world. However, traditionally those working in the financial sector are largely unaware of the rationale and pressures for sustainable development and its bearing on their work, while those in the relevant research and policy areas commonly overlook how vital the financial sector is for progress.
