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)

“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 one of the most exciting forums for anyone who wants to understand and shape the future of sustainable and responsible digital infrastructure. It brings together the right mix of technical depth, practical insight, and real-world challenges!

Shaolei Ren, Associate Professor (University of California)

“I’m not new to sustainability, yet I am fairly new to finding like-minded people to talk to about it. My entry points were my local Green Software and GreenSEO meetup groups. So, coming to Green IO, I knew there were some good speakers, but I didn’t know what to expect in terms of vibe. How brilliantly surprised I was! This is not your standard corporate sales-fest; Green IO is the real deal. A conference full of people doing work they care about for the good of the planet – I’ve found my clan and I’ll be back!”

Fiona MacNeill, Director - UX (Research & Strategy, Macknowlogist)
