Sustainability leadership: Conceptual foundations and research landscape

Sustainability leadership (SL) is a complex and relevant phenomenon that can contribute to several types of organisations during the process of becoming more sustainability-oriented. Over the past few years, a considerable number of publications have increased the level of knowledge in this field; however, on the other hand, it also has generated more complexity, literature dispersity and lack of complete understanding of the possible research avenues on SL. This paper aims to address this by complementing and building on previous qualitative and quantitative studies of SL by unveiling and exploring the landscape of the research field. This study differs from prior research in three main ways: (1) explores how the term SL evolved from the leadership theory, (2) explores the research streams that scholars have been conducting in the field by adopting a robust search string revised by specialists and considering a wide range of terms related to formal and informal leadership, as well as sustainability-related terms and (3) understands how the several leadership theories and styles are connected to sustainable development (SD) and corporate social responsibility (CSR). After applying the inclusion and exclusion criteria, a total of 1,813 well-cited papers published in top journals that directly tackle sustainability leadership were selected. This sample was then used for the bibliometric assessment based on the co-occurrence of terms technique. The results indicate the existence of four main clusters and twelve subclusters, which can be considered research strands. In addition, this study also explores how the selected studies build on several leadership theories in order to understand how leadership aspects can contribute to SD and CSR adoption
