The aim of this talk is to critically analyse the use of digital technology in the current context of global ecological injustice and the collapse of ecosystems.

The challenges are huge and include the digital world's hunger for energy as well as the exploitative global practices of tech companies or the discussion of the current AI sustainability hype. But which digital tools make sense, which do not and how can we achieve global social emancipation from self-destructive structures and towards ecological sustainability and a and a just world?
