Call for speakers open until 20 October 2026!
This year's theme: Bring Tech Home: From Dependency to Sustainability. We are looking for talks and workshops on four tracks:
- Silicon and Second Life: reshoring hardware, repair, reuse and e-waste
- Models Without the Detour, With Impact: sovereign inference, local fine-tuning, frugal AI and AI for good
- Infrastructure and the Energy Dividend of Local Inference: data centres closer to clean, local power
- The Builders of a Resilient Europe: the people, policies and organisations making it real
Tech practitioners and sustainability experts, academics and industry leaders alike: bring us what you have measured, built and learned. Talks in English or French.
... and more to come!
Why they attended our past Paris editions
"Attending the Green IO conference is an absolute must for anyone passionate about sustainable IT. It’s the perfect place to discover cutting-edge tools, proven best practices, and practical strategies to effectively measure and minimize your IT environmental impact."
Pierre Seroul,Head of Data & Energy Efficiency Domain (Eviden)“I am generally lukewarm on sustainability conferences these days, but one I always recommend is Green IO 🎙️. Why? 1. It is co-located with "mainstream" tech conferences, leading to the cross-pollination that we so desperately need. 2. Gaël DUEZ and team do an excellent job curating a technical yet accessible agenda (https://lnkd.in/gAEzz45W) focused on specific examples of action. 3. This heavily reduces the amount of empty corporate PR presentations.”
Boris GamazaychikovBoris Gamazaychikov, Head of AI Sustainability (Salesforce)“Thank you Green IO 🎙️ team for the highly inspiring conference, bringing the experts and building the community!”
