This paper provides a scoping review of European sustainability reporting studies. Previous sustainability studies do not offer a comprehensive discussion of features key to the European setting. Despite their important role in the European economy, research on small and medium-sized enterprises (SMEs) and financial institutions (i.e. insurers and banks) is limited. Furthermore, regions in southern and particularly eastern Europe, which are critical given regulators’ objectives for European Union-wide and global sustainability standards, are neglected. Finally, studies on non-financial effects of sustainability reporting are also limited, and only a few studies differentiate between stakeholder- and shareholder-oriented countries. This is needed for a holistic view on sustainability beyond financial performance. Based on material issues identified for the European context, our study provides a research agenda based on comprehensive and rigorous scientific evidence on the state of the art of sustainability research in Europe.
