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!

Never miss a conference!

Why they attended our past editions

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)

“There are few opportunities to compare our greentech practices with those of our colleagues and to get moving. Green IO Paris allowed us to mobilize a small Product and Engineering collective at leboncoin during the Sustainable Challenge to experiment on our platform with eco-design or optimization gestures for our product, but also to raise awareness among curious people during the conference."

Guillaume Grillat, Lead Tech Community Advocate (LeBonCoin)

“It’s a great place to learn from you peers [...] and it’s great energy to surrounded by people as passionate about the topic as I am”

Venetia FOO, Sustainability Lead (Palo IT)

“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)
