As resources become scarcer, the interest of politics and research has recently focused increasingly on new concepts of economic action. Behind this are catchwords such as green economy and entrepreneurs with social and societal responsibility. In the beginning, the sustainability debate included the economical use of finite resources. In the course of time, the perspective broadened. In addition to the ecological point of view, all factors used for production have now been included, i.e. sustainable management refers to the preservation of the natural basis of life as well as to the long-term existence of the company and finally also to the well-being of the people working in it.
