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!

Never miss a conference!

Why they attended our past editions

"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 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)

Green IO conference is not only for professionals of the intersection between sustainability and software engineering. It’s a space for developers, engineering leaders and business to connect and share their experiences. It’s for everyone, who want to integrate sustainable practices in their daily work, regardless in which area you are working. I am very glad to see how the community is growing and building connections that continue after the conference as well.

Bjorna Kalaja, Senior Software Engineer (foryouandyourcustomers Vienna)

Green IO is the conference for learning about sustainable computing. The discussions and workshops cover the latest advances, and it is the only place where you will meet the leaders in the field. As a conference speaker, this is the place where I most wanted to share insights on consulting in digital emissions. Sharing the stage with the experts will be a longtime memory.
