To obtain the concept of sustainability, it is not enough to analyse the economic and ecological aspect. Therefore the social aspect was defined as the third dimension of the concept of sustainability. To be able to evaluate the social relevant aspect of a product or technology, United Nations Environment Programme has defined five major stakeholders including their subcategories. With the guidelines from UNEP and the already existing social compatibility analysis – this paper seeks to create a new method. Therefore the SCA and the guidelines from UNEP will be combined to be able to evaluate social hotspots from any product. First of all it was necessary to combine the already existing methods and tools like SCA with UNEP properly. This is why the Relevance Analysis was created – which suits the needs of both methods extremely well. By using the Social Hotspots Database to fill the gaps of the Relevance Analysis, a first result has been achieved. To evaluate the result, a second method has been developed. With the Performance Reference Point is it possible to highlight possible social hotspots and compare them with other products or aspects. It has shown that both methods are working very well together. Depending on the quality of the data source it is thus possible to locate social hotspots with their impact on the product. In a second approach it is necessary to calculate the needed working hours to replace the mass in order to achieve better results.
