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)

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)

"Apidays London was a great conference, specifically the Green IO sustainability conference. Not something I have seen before but thought provoking and inspirational.”

Michala, Chief of Staff for SRE (Goldman Sachs)

“I am generally lukewarm on sustainability conferences these days, but one I always recommend is Green IO 🎙️. Why? 1. It is co-located with "mainstream" tech conferences, leading to the cross-pollination that we so desperately need. 2. Gaël DUEZ and team do an excellent job curating a technical yet accessible agenda (https://lnkd.in/gAEzz45W) focused on specific examples of action. 3. This heavily reduces the amount of empty corporate PR presentations.”
