Resumen
Organizations worldwide have adopted sustainability strategies to enhance their productivity and develop a competitive advantage. More often than not, organizations and their leaders develop a narrow view of sustainability and consider only the aspects of sustainability that are directly related to their sphere of performance (internal sustainability). Yet, sustainability issues impact all business and non-business organizations, as well as the long-term sustainability of international business relations and quality of life issues worldwide (external sustainability). An increase of appropriate sustainability efforts often requires expanding beyond conventional thinking. Economic necessity can drive both internal and external sustainability measures. Leadership effort is essential to enable shifts in organizational culture that enable sustainability efforts to succeed. This article discusses the sustainability movement. After defining internal and external sustainability, this paper discusses the philosophy of sustainability, internal and external sustainability, measurements, leadership, and best practices.
