It is the nature of powerful ideas that they can summarize a ground-breaking concept in a plain and simple message. In this sense, the concept of sustainability is one such idea. It translates into a compelling orientation towards the future. It is this orientation towards the future that is needed today in order to understand and address the challenges of tomorrow. However, many critics object that sustainability is not (yet) a clear-cut concept for definite implementation. They argue that although we have already learned a great deal about sustainable development, the concept itself still fails to provide us with a straightforwardmanual for solving everyday problems in society, management, or politics. Companies in particular are said to still lack a clear understanding of how to put sustainability into practice.
