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)

"I've been attending (almost) all Sustainable IT conferences in Europe... and none of them has an equivalent line up, with so nice speakers and so much representants of all ecosystems across the continent. If you ever want to come and meet the EU Sustainable IT ecosystem, GreenIO Paris is the place to be!"

Amael Parreaux-Ey, CEO (Resilio)

“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)

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.

Susannah Hill, Co-Founder (Cloud Sustainability Watch)
