Great hopes have been placed in IT and Digital Technologies to support our transition towards a low-carbon economy, but the digital sector itself emits as many greenhouse gases as the world's entire road freight. Let's make sure we clean our own house while helping to make the world a better place!

Why they attended our past editions

Green IO is one of the most exciting forums for anyone who wants to understand and shape the future of sustainable and responsible digital infrastructure. It brings together the right mix of technical depth, practical insight, and real-world challenges!

Shaolei Ren, Associate Professor (University of California)

“The Green IO conference in Paris this year was highly appreciated for its practical approaches to digital sustainability, grounded in the real-life experiences and shared insights of development teams and architects.”

Maija Fournier, Platform Architect (OECD)

“Brilliant conference - been one of the highlights of my year. So great to see the room full for every talk and so many great questions!”

Richard Kenny, Founder and Managing Director (Interact)

Thank you Gaël DUEZ for hosting a fantastic conference. I loved participating and as a speaker I was grateful for the warm welcome from the audience. Additionally, I was able to make hugely valuable connections, which will no doubt be helpful to to meet our ambitious Carbon Zero targets at Cambridge University Press & Assessment. Can't wait for next year!!

Julie Dennis, CTO (Cambridge University Press & Assessment)
