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

"Attending the Green IO conference is an absolute must for anyone passionate about sustainable IT. It’s the perfect place to discover cutting-edge tools, proven best practices, and practical strategies to effectively measure and minimize your IT environmental impact."

Pierre Seroul,Head of Data & Energy Efficiency Domain (Eviden)

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)

“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)

“There are few opportunities to compare our greentech practices with those of our colleagues and to get moving. Green IO Paris allowed us to mobilize a small Product and Engineering collective at leboncoin during the Sustainable Challenge to experiment on our platform with eco-design or optimization gestures for our product, but also to raise awareness among curious people during the conference."

Guillaume Grillat, Lead Tech Community Advocate (LeBonCoin)
