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

“Great set of speakers with a shared passion to have a conscious awareness of a sustainable use of tech to have a real positive impact on people and planet”

Rob Price, Founder (Accelleo)

Most tech conferences are marketplaces dressed up as content. Green IO is one of the few that’s about the cause – finding new approaches, sharing what actually works, and connecting the people who can move the industry forward. That's rare, and it's why I will certainly be back.

Matthias Haymoz, Executive Director (SDEA)

“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 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)
