The evaluations are mainly based on publicly available information. On the one hand, this is information that the evaluated companies publish themselves, such as annual reports or sustainability reports. On the other hand, the actual behaviour of companies is also surveyed. This is done by analyzing publications of trustworthy third parties, such as media or NGO reports and studies.
In addition, data that we have modelled is also included in the evaluation, which is based on our own research and experience.
