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

“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 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)

"Apidays London was a great conference, specifically the Green IO sustainability conference. Not something I have seen before but thought provoking and inspirational.”

Michala, Chief of Staff for SRE (Goldman Sachs)

Green IO is the conference for learning about sustainable computing. The discussions and workshops cover the latest advances, and it is the only place where you will meet the leaders in the field. As a conference speaker, this is the place where I most wanted to share insights on consulting in digital emissions. Sharing the stage with the experts will be a longtime memory.
