COEUS tackles the challenge not only of ensuring that digitalisation is achieved in Central Europe (CE), but that it is achieved with social, economic, technological and environmental responsibility. It does so by supporting Corporate Digital Responsibility (CDR) skills for traditional and innovative SMEs, with a focus on smart specialisation priorities for digitalisation. COEUS uses transnational cooperation to co-design and co-implement a transnational pilot to test and validate a SME CDR upskilling/reskilling programme. In parallel, the project builds capacities of public authorities and stakeholders to support CDR skill uptake. COEUS is the first transnational project in the programme area to address all areas of the relatively new and complex topic of CDR.
