Summer School 2025

Thomas Breuzard is a major family shareholder in the Norsys Group and Chair of the Norsys High Committee for Nature, where he is currently leading the roll-out of ‘permaentreprise’, a viable development model for a liveable future invented at Norsys. He is also co-Chair of the B Corp movement in France and sits on the board of directors of Mouvement Impact France.  

Thomas Breuzard holds an MBA in international trade and marketing. He began his career in sustainable development consultancy and worked with major groups and SMEs on defining and implementing their CSR strategies. This pragmatic utopian now works in the family business founded by his father, the Norsys Group, a digital services company with over 750 employees, which he has led along the path of B Corp and the société à mission (a status reserved for certain companies whose activity has a societal purpose) to strengthen the alignment between its business and its societal commitment.  

Frantz Gault is one of the few specialists in the representativeness of Nature in corporate governance. As such, he has been appointed Nature's representative on the Norsys Group board of directors (with 10% voting/veto rights) and recently published “La nature au travail” (Nature at work) with EPFL (École polytechnique fédérale de Lausanne) that proposes a new way of thinking about the relationship between Nature and work. He is the author of Apocalypse Work, an essay published by Dunod which examines work, its meaning and its methods, in the light of the ecological crisis. 

A graduate of Sciences-Po in organisational sociology, he studied the anthropology of Nature at the Collège de France, which led him to produce “Natura Naturans”, a documentary questioning the concept of Nature. From 2010 to 2020, Frantz has been a major reference in the field of teleworking in France. In this capacity, he has supported most of the major companies and taken part in public consultations on the subject.

His work focuses on the relationship between well-being and sustainability through the social-ecological approach, in particular the exploration of the sustainability-justice nexus (just transitions) and planetary health-human health nexus (“full health nexus”).
