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

“The Green IO conference in Paris this year was highly appreciated for its practical approaches to digital sustainability, grounded in the real-life experiences and shared insights of development teams and architects.”

Maija Fournier, Platform Architect (OECD)

"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)

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

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.
