Digital technologies are seen as enablers of green transition, circular economy, social progress, and more resource efficient societies. At the same time, digital technologies are also criticised for being unsustainable in terms of energy and resource consumption and the division of labour on which they rest. On this background, this article conducts a scoping review on how digital technologies are related to sustainability in compulsory education. The review finds a dichotomous approach to digital technologies as either tools for learning and sustainable development or, conversely, as problems for sustainable development. Sustainability is either approached as a political goal towards which (educational) technologies can contribute; a problem to be solved through technological solutions; something which requires increased human awareness (created with technologies); or something which is challenged by technologies themselves.
