As UX designers we put the user into the center of our work. This is how we define our job: creating outstanding experiences for the users, but, in these times we have to take responsibility for more than just the users. As the great polar explorer Robert Swan once said: „The biggest threat to our planet is the belief that someone else will save it.“ But what can we as UX Designers do to drive sustainability and make our work more sustainable? What does Sustainable UX even mean? To answer these questions a group of designers created the non-profit initiative „SUX - The Sustainable UX Playbook“. SUX is a community with more than 1000 designers from all over the world sharing ideas as well as an active workshop space with more than 100 people actively working on ideas how to drive sustainability. Thorsten will give you an overview about Sustainable UX and the aspects of Sustainability in UX. And Thorsten will end with an overview about the initiative SUX.
