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

“Sustainability is one of the most important subjects facing technology companies today. The Green IO conference is without doubt one of the best places to learn about industry best practices, to exchange ideas and to discuss with others facing similar challenges.”

Diarmuid GILL, CTO (Criteo)

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)

“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.”

Boris GamazaychikovBoris Gamazaychikov, Head of AI Sustainability (Salesforce)

The GreenIO conference in NYC was an important reminder for us that technology is not just about growth at all cost. I got a lot of useful insights from the sessions on all aspects of digital sustainability, including indepth case study from employees at leading companies, and many great face to face interactions with sustainability leaders during the social events.
