The 2026 edition of the 4th Green and Solidarity Finance Meetings will take place from November 19 to 20, 2026, with an unusual start. The event, typically beginning on Friday, will open on Thursday, November 19, with a debate conference. This change aims to build anticipation and set the tone for the discussions that will follow. The theme of this edition is "Sustainable financing for robust companies," a concept that emphasizes the importance of creating resilient and environmentally responsible businesses. Olivier Hamant, a research director at INRAE in the Plant Reproduction and Development Laboratory (RDP) at the ENS de Lyon, will introduce the theme. Hamant is also the director of the Michel Serres Institute, an organization dedicated to exploring philosophical and scientific questions related to resilience and sustainability. He has written extensively on the topic of robustness, publishing several books, including Chronicles of a Cracking World, The Robust Company, On Inconsistency: A Political Philosophy of Robustness, The Third Way of Life, and Antidote to the Cult of Performance: The Robustness of Life. His work has appeared in the Gallimard Tracts collection, a series known for its sharp and critical analyses. Hamant has authored over a hundred scientific articles and is widely regarded as one of the leading experts on the robustness of life. His research explores how biological systems adapt and endure, and he applies these insights to help companies and institutions transition to more sustainable economic models. His work bridges the gap between science and practical application, offering real-world solutions to complex challenges. The debate will be moderated by Christian Apothéloz, a journalist from Gomet', the organization hosting the event. Due to the limited number of available spots, registration is required for attendance. The event aims to bring together experts, business leaders, and policymakers to discuss the future of sustainable finance and the role of robustness in building resilient economies.
