We expect a lot from companies: not only should they offer good and inexpensive products and services, but they also should assume responsibility for the impact their products have on the public and environment. Companies must therefore consider ecological and social requirements as they relate to their core business, their local environment and along their supply chain. In short: companies should aim for a corporate strategy that follows the principle of sustainability. With research and advice, the IÖW supports companies on their way to adopting sustainable strategies. Our proficiency comprises the development, testing and evaluation of methods and instruments for sustainable corporate management as well as for communication with stakeholders.
