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)

“This was my second year at Green IO and I was so honoured to be on stage for a second year as well and the growth, and bigger stage! gave me goosebumps. I walked away inspired and having learnt things that we’ll be applying to our own digital sustainability projects. But mainly the sense of community that I felt at the conference was incredible and uplifting and it has inspired me to reignite getting more involved in the wider digital sustainability community as well.”

Andri Johnston, Digital Sustainability Lead (Cambridge University Press and Assessment)

Whether a newbie or a practitioner, there's something for everyone's taste on the GreenIO menu. The GreenIO conference is a perfect opportunity to share Digital Sustainability practices in the industry and explore new solutions from amazing startups. Regardless of your company's size, you'll be inspired by both the audience and the speakers, leaving you wanting more.

Laurie Servais, Sustainable IT Officer (Airbus)

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.
