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

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

James Martin, Founder (BetterTech)

The GreenIO team put together a great conference; it was packed with enjoyable speakers, engaging content, and a great network of Green IT practitioners. It's a great place to learn practical tips on how to decarbonize your software stack and build out your network of sustainability professionals.

Will Alpine, Cofounder (Enabled Emissions Campaign)

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)

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.
