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)

“Thank you Green IO 🎙️ team for the highly inspiring conference, bringing the experts and building the community!”

Maja Trajanoska, Software Engineer (G+D Netcetera)

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.

Pascal Joly, Founder, IT Climate Ed

"I've been attending (almost) all Sustainable IT conferences in Europe... and none of them has an equivalent line up, with so nice speakers and so much representants of all ecosystems across the continent. If you ever want to come and meet the EU Sustainable IT ecosystem, GreenIO Paris is the place to be!"

Amael Parreaux-Ey, CEO (Resilio)
