Competences are intensively discussed in the context of cross-curricular themes, such as Sustainable Development and Education for Sustainable Development (ESD), especially in light of the United Nations Decade for ESD (2004-2015). Recent literature on ESD lists a number of competences for ESD in various fields with the exception of teacher education. A competence model for ESD for educators was generated in the Austrian research project KOM-BiNE (Competences for ESD in Teacher Education) as part of a large-scale EU project. The KOM-BiNE competence model consists of areas of competences within fields of action. The constituent elements of the competence model are described in detail and are illustrated with examples.
