Companies still need methods and tools that support them to reach sustainable development. The beginning of the discussion about sustainability can be dated back to 1732, but nowadays the expectation that companies are sustainable is more and more relevant to the companies. To develop the right methods, which are really helpful for the companies it is necessary to understand the current state of the art. What do companies already do, where do they have problems, and which barriers do they see when integrating sustainability. To investigate these questions we conducted an online-survey with German companies. Our study showed that companies are still at its beginning and that the level of sustainability integration in Germany is not very high. Especially the integration into business process management and the use of information and communication technology need more focus. The biggest problems companies see when trying to integrate sustainability are the missing resources and the missing methodological skills, which supports our assumption that companies still need support. The next step will be the development of these methods and tools.
