Changing the brief: a day to rethink professional events

On October 6, 2026, in Nantes, the Nantes Saint-Nazaire Convention Bureau will launch the first edition of “Changer le brief,” a one-day event dedicated to the changes taking place in the professional events industry and the concrete solutions emerging within the sector.

How can we design events that are useful, appealing, and responsible, given the current context of ecological transition, economic pressures, and changing participant expectations? The Nantes Saint-Nazaire Convention Bureau is hosting a day of discussions and workshops featuring a diverse panel of stakeholders to explore these fundamental questions in the organization of professional events.

Supported by ADEME and UNIMEV, this event will bring together experts, organizers, agencies, event venues, service providers, and institutions around a shared goal: to evolve practices in order to build a more sustainable, more resilient events industry that creates greater value for local communities.

Moving from Thought to Action

Event professionals today are facing numerous changes: environmental requirements, budget constraints, new work practices, shifts in mobility, and growing expectations regarding impact and value. Changing the Brief offers a step back to reflect on these changes, but above all, it aims to share solutions and experiences that can be directly applied.

The day’s program includes lectures, plenary sessions, hands-on workshops, feedback, and testimonials from people working in the field—all designed to bring together different perspectives and provide professionals with the tools they need to advance their projects.

Among the prominent figures gathered in Nantes:

  • Valérie Martin, head of ADEME’s Citizen Engagement and Media Division;
  • Thierry Gintrand, UNIMEV regional representative and CEO of Angers Loire Tourisme Expo Congrès;
  • Marie Barsacq, CEO of Paris Entertainment Company, who will speak on the challenges of legacy and evolution in major events;
  • Aurore Deliancourt, Director of Impact at Auditoire;
  • Geneviève Leclerc, co-founder and CEO of Meet4Impact—an international leader in the field of event impact and legacy—will kick off the day with a presentation on the value, purpose, and legacy of events.

Practical solutions led by the industry

Because the transformation of the events industry is also taking shape on the ground, *Changer le brief* will give prominent coverage to the initiatives and expertise of professionals involved in these changes.

Several participants will share their experiences and offer training workshops on specific topics:

  • Climeet, a specialist in measuring the environmental impact of events;
  • MUTO, focused on the reuse of event sets and materials;
  • Stéphane Mira, instructor in generative AI applied to the events industry;
  • REEVE, a network dedicated to the ecological transition of events;
  • La Ressourcerie Culturelle, on the issues of Reuse and eco-design;
  • The Acclimatization Office, which will share its findings on participants' mobility;
  • Mixt, a Nantes-based venue designed around the principles of simplicity, Reuse, and the circular economy, will host this first edition.

Adapt the brief to evolve the event

Beyond simply taking stock of the changes underway, *Changer le brief* aims to highlight the initiatives that are driving change across the entire industry.

The goal: to provide professionals with concrete courses of action to address the new challenges facing the events industry, while examining the role and contribution of events in local communities.

A day to share experiences, try out new approaches, and—together—rewrite the brief.
