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

“This was my second year at Green IO and I was so honoured to be on stage for a second year as well and the growth, and bigger stage! gave me goosebumps. I walked away inspired and having learnt things that we’ll be applying to our own digital sustainability projects. But mainly the sense of community that I felt at the conference was incredible and uplifting and it has inspired me to reignite getting more involved in the wider digital sustainability community as well.”

Andri Johnston, Digital Sustainability Lead (Cambridge University Press and Assessment)

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.

Susannah Hill, Co-Founder (Cloud Sustainability Watch)

“The Green IO conference in Paris this year was highly appreciated for its practical approaches to digital sustainability, grounded in the real-life experiences and shared insights of development teams and architects.”

Maija Fournier, Platform Architect (OECD)

"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)
