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)

The GreenIO team put together a great conference; it was packed with enjoyable speakers, engaging content, and a great network of Green IT practitioners. It's a great place to learn practical tips on how to decarbonize your software stack and build out your network of sustainability professionals.
