Books, papers, blogs, and interviews


Dr. Marcel Jeucken is the 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 the sustainable development of the world. The 1998 (Dutch) and 2001 (English) book posited that as follows: "Traditionally, however, those who work in the financial sector are largely unaware of the rationale and pressures for sustainable development and their impact on their work, while those in the relevant research and policy fields usually overlook how essential the financial sector is to progress."
