Corporate sustainability has become a topic of increasing importance for business leaders. A growing number of them are committing their organisations to corporate sustainability, a form of self-regulation which seeks to preserve social, environmental, and economic capital. This requires leaders to engage in transformational change, challenging organisational paradigms and introducing sustainable values into their organisations. Despite a considerable body of research on leadership in business, there is limited work to date on understanding the relationship between leadership and corporate sustainability. This conceptual paper begins to address this gap by exploring the concept of sustainable leadership. It proposes four types of leaders and the business context in which those leaders may be appropriate. This paper aims to locate sustainable leadership within a leadership typology which compares leadership approach with environmental beliefs. This may be used to better understand how leadership influences corporate sustainability within organisations.
