This report presents a preliminary literature review and frameworks analysis used for the preparation of the initial phases of the design process of the European Sustainability Competence Framework (GreenComp). Specifically, it includes a literature review conducted between October 2020 and February 2021, and an initial set of competences, to be used as a synthesis of the work done in the fields that contributed to the definition of the sustainability competences or for subsequent expert consultations. This preliminary set of competences especially aimed to be functional for all levels and areas of Lifelong Learning, from early childhood to old age, in formal, non-formal and informal contexts. The report also includes a section on Education for Sustainability as a unique tool to facilitate the learning of the competences. Furthermore, it provides examples of Education for Sustainability behavioural learning objectives and examples of the contribution that the acquisition of sustainability competences can potentially give to the implementation of the EU policy instruments conceived to accelerate the shift to a circular and low carbon economy (e.g., EU Ecolabel, Green Public Procurement or the EU taxonomy for sustainable activities). Finally, benefits and recommendations for scaling up Education for Sustainability are presented.
