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

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 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)

"I've been attending (almost) all Sustainable IT conferences in Europe... and none of them has an equivalent line up, with so nice speakers and so much representants of all ecosystems across the continent. If you ever want to come and meet the EU Sustainable IT ecosystem, GreenIO Paris is the place to be!"

Amael Parreaux-Ey, CEO (Resilio)

"The engagement is so much higher than most conferences. The short format for presentations with a single stage works very well. Also avoiding the tiresome stock standard corporate pitches that can weigh down other conferences."

Kevin Leslie, Chief Revenue Officer (Greenpixie)
