Let's make sure we clean our own house while helping to make the world a better place!

“Thanks again for inviting me to join the panel discussion at GreenIO. The energy and passion in the room was brimming which is always very encouraging! Great job on such a successful event.”

Lydia Tabbron, Digital Sustainability Lead (DEFRA)

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.
