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 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.
