Diploma in Sustainable Business


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.

A 10-month team consulting project in the area of business sustainability is an integral part of the Diploma in Sustainable Business program. It is a unique opportunity for participants to engage in real-life projects with companies and work as advisors on strategic sustainability problems. Consulting projects include a wide range of relevant issues in product development, purchasing, supply chain, market analysis, labelling, employer branding, and communications. They are carried out by small, international and multifunctional teams of students (3-5 course participants) who work closely with the sponsoring company and are guided by the BSL-University of St. Gallen experienced faculty throughout the complete project cycle. The projects allow participants to increase their work experience prior to graduation, expand their professional network, and enhance their long-term career possibilities.

Participants who have successfully completed the program are awarded a Diploma in Sustainable Business by BSL and the University of St. Gallen.

New: The modular format of the program allows you to attend a course of your interest as a separate 2-day seminar. You can sign up for any seminar included in our offering or request a customized training tailored to the specific needs of your company (a minimum number of 8 participants is required).

Completing a single 2-day course will not only provide you with knowledge and insight on a specific topic, but can also help you assess whether the program is a good fit for you.

The most important personal insight for me was to see that my background in international development adds significant value to a for-profit business. Having mainly worked in the public sector, I was never sure about how I could leverage my knowledge and experience in the business world. As a result of the project experience I have gained a lot of confidence as regards leveraging my own capacities in a business context and I feel well equipped to embark on my further journey in leading change for a more sustainable future.
