Program overview

The Diploma in Sustainable Business will enable you to comprehend and respond to global challenges from the perspective of business as a force for good.

The Diploma in Sustainable Business is a joint program of Business School Lausanne and the Institute for Economy and the Environment of University of St. Gallen (IWÖ-HSG), and is endorsed by the World Business Council for Sustainable Development (WBCSD). This is a one-year, part-time executive program which includes not only subject knowledge in the field of sustainable business, but also leading change and project management experience as part of the course. Participants who have successfully completed the program are awarded a Diploma (DAS) in Sustainable Business by BSL and the University of St. Gallen.

Program Objectives

  • You will undertake a transformational journey of self-discovery through personal development classes and reflective thinking. You will redefine leadership from the perspective of leading yourself and others towards a better world.
  • You will discover state-of-the-art concepts and tools for tackling global challenges related to the economic, environmental, and social impact of business. You will turn business on its head and will explore an outside-in perspective which redefines business strategies as being driven by sustainability challenges.
  • You will move beyond academic exploration from day one and will have the chance to make a positive contribution to a real organization within the program. You will apply what you learn straight away by immersing yourself in a 10-month company consulting project with fellow course participants.

Consulting Project

The Consulting Project is an integral part of the program experience and a stepping stone in your preparation as a business sustainability professional. Consulting projects are given by organizations based in Switzerland and include a wide range of strategically relevant challenges in product development, purchasing, supply chain, market analysis, labelling, employer branding, and communications. Projects are assigned to small, multi-faceted teams of 3-5 course participants. Teams are mentored by experienced faculty, providing continuous support and feedback throughout the program.
