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 was a blast! Thanks again Gaël & team for gathering such a positive & optimistic bunch of responsible technologists 💚”

James Martin, Founder (BetterTech)

"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)

“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 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.
