With the 'twin transition', the European Union aims to combine digitalisation and sustainability in order to achieve the United Nations Sustainable Development Goals. The research project "Digitalisation and sustainability at EU level" examined the opportunities and risks of digitalisation for the implementation of the 2030 Agenda for Sustainable Development. The analysis showed that these two topics are often not integrated. Recommendations were developed for digital circular economy, sufficiency and environmental justice. The research findings suggest that environmental and social justice should be at the forefront of future efforts to promote a sustainable digital future.
