The importance of green innovation management is growing both in practice and in academia. This paper provides a current overview of the existing body of literature in the field of green innovations, identifying the most active scholars, institutions and relevant publications. It also contributes to a clarification of the concept 'green innovation'. The review explains that three different notions of green, eco/ecological and environmental innovation are used largely synonymously, while the notion of sustainable innovation broadens the concept and includes a social dimension. According to this review, the most active scholars are situated in Europe (especially the Netherlands, Italy and Germany). A ranking is provided of innovation management journals by their total number of green innovation publications. The paper stimulates discussion about the adequacy of research in this subject area (managing green innovation) and the dearth of comprehensive literature reviews.
