Let's make sure we clean our own house while helping to make the world a better place!

Why they attended our past editions

“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)

What makes GreenIO special is how it bridges the gap between the technical realm and the climate crisis. As a designer, I was surprised to find myself riveted by even the most esoteric and technical topics. The quality of the speakers and the breadth of content were exceptional.

James Christie, User Experience Director (SustaianbleUX)

“It was a blast! Thanks again Gaël & team for gathering such a positive & optimistic bunch of responsible technologists 💚”

James Martin, Founder (BetterTech)

“Sustainability is one of the most important subjects facing technology companies today. The Green IO conference is without doubt one of the best places to learn about industry best practices, to exchange ideas and to discuss with others facing similar challenges.”

Diarmuid GILL, CTO (Criteo)
