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

“Sustainability is one of the most important subjects facing technology companies today. The Green IO conference is without doubt one of the best places to learn about industry best practices, to exchange ideas and to discuss with others facing similar challenges.”

Diarmuid GILL, CTO (Criteo)

Green IO conference is not only for professionals of the intersection between sustainability and software engineering. It’s a space for developers, engineering leaders and business to connect and share their experiences. It’s for everyone, who want to integrate sustainable practices in their daily work, regardless in which area you are working. I am very glad to see how the community is growing and building connections that continue after the conference as well.

Bjorna Kalaja, Senior Software Engineer (foryouandyourcustomers Vienna)

It was a joy to attend Green IO Munich! As a former Green IO guest and someone who has been championing more sustainable tech since 2016, the Green IO conference series embodies everything I have been advocating for. To experience it in person – the community, the passion, the solutions, the inspiring stories of how people are working to make a difference. It embodies what I had hoped to realize in this space, what I imagined it could look like. I am so grateful to Gaël for everything he's done to foster this community

Michael J. Oghia, Partnerships Manager & Co-producer (Datacenter Changemakers)

The GreenIO conference in NYC was an important reminder for us that technology is not just about growth at all cost. I got a lot of useful insights from the sessions on all aspects of digital sustainability, including indepth case study from employees at leading companies, and many great face to face interactions with sustainability leaders during the social events.
