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)

Green IO New York brought together the forward-thinking and passionate leaders of sustainable computing for two days of knowledge sharing that created valuable new projects and partnerships in digital climate action. It was inspiring.

Susannah Hill, Co-Founder (Cloud Sustainability Watch)

Green IO is one of the most exciting forums for anyone who wants to understand and shape the future of sustainable and responsible digital infrastructure. It brings together the right mix of technical depth, practical insight, and real-world challenges!

Shaolei Ren, Associate Professor (University of California)

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)
