Universities can be considered a key element in promoting sustainable development through education, research, innovation and social leadership. In this educational-focused article, we discuss the need to provide students with the knowledge and skills needed to understand and address sustainability challenges. To do this, it will be very important to introduce sustainability – and also other related concepts – in university curriculums and, in particular, in Economic and Business courses, where future business leaders are currently being formed. For this reason, the article presented has a double objective, on the one hand, to answer this question: what are we teaching about this topic in universities and, in particular, in Economics and Business courses; and on the other hand: how are we integrating it into curriculum. The article reviews over time the main subjects that have covered this topic – from business ethics to ESG criteria, to CSR – and proposes different strategies to integrate this content into the curriculum.
