We need to integrate socioecological issues into our activities. Engineers and designers need to develop competencies in sustainability, but it exists a lack of support in an academic context and for the training of professionals. The aim of this article is to demonstrate that the Doughnut is a support for developing sustainability competencies. In the literature, these competencies are identified and pedagogical experiences on their integration in engineering curricula are reported. We use the doughnut in a workshop as an element of understanding and developing competencies for sustainability.
