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

“It’s a great place to learn from you peers [...] and it’s great energy to surrounded by people as passionate about the topic as I am”

Venetia FOO, Sustainability Lead (Palo IT)

The Green IO Conference is more essential than ever, especially with the rise of AI, whose environmental impact must also be measured and optimized within our organizations. But that is not all—the timing is critical. When sustainability comes rushing back to the forefront, faster than you might expect the teams that have already embedded it will be ready. And you will know that you persevered and made the right choices. While visiting the remarkable, small, and recently opened Fernand Léger Museum in Argentan, I came across one of his quotes that struck me. Léger, a master of contrast and modernity, inspired me to adapt his words by replacing “painter” with “IT professional.” It becomes: “As an IT professional, I believe in the significant role of my peers in the evolution of society.” Every IT professional carries responsibility for shaping society and for the environmental footprint of the digital sector. On one hand, we must understand, control, and reduce the environmental impact of digital transformation in organizations. On the other, we must also assess and measure its benefits.

Christophe Debuysscher, European, ICT Sustainability Manager (European Patent Office)

“Brilliant conference - been one of the highlights of my year. So great to see the room full for every talk and so many great questions!”

Richard Kenny, Founder and Managing Director (Interact)

“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)
