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

“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.”

"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)

It was a joy to attend Green IO Munich! As a former Green IO guest and someone who has been championing more sustainable tech since 2016, the Green IO conference series embodies everything I have been advocating for. To experience it in person – the community, the passion, the solutions, the inspiring stories of how people are working to make a difference. It embodies what I had hoped to realize in this space, what I imagined it could look like. I am so grateful to Gaël for everything he's done to foster this community

Michael J. Oghia, Partnerships Manager & Co-producer (Datacenter Changemakers)

The GreenIO team put together a great conference; it was packed with enjoyable speakers, engaging content, and a great network of Green IT practitioners. It's a great place to learn practical tips on how to decarbonize your software stack and build out your network of sustainability professionals.
