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 really cool to interact with such a great, international audience which was very focused on the topic at hand. The talks were amazing! I'm looking forward to the next edition.”

Tristan Nitot, Digital Commons and sustainable IT Ambassador (Octo Technology)

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)

"The engagement is so much higher than most conferences. The short format for presentations with a single stage works very well. Also avoiding the tiresome stock standard corporate pitches that can weigh down other conferences."

Kevin Leslie, Chief Revenue Officer (Greenpixie)

“Thank you Green IO 🎙️ team for the highly inspiring conference, bringing the experts and building the community!”

Maja Trajanoska, Software Engineer (G+D Netcetera)
