What can I do for you?

SustFin brings broad managerial, project management and executive experience to any organisation in need of an interim position or project management on the crossroads of sustainability and finance. These services can be very focussed or broad in scope depending on your needs. SustFin also assists organisations with trainings, communication and stakeholder management, and with second opinions on internally developed RI policy and implementation initiatives. SustFin builds on extensive expertise and experience in fiduciary advice,  asset management, and banking, across all product lines and practices.

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.
