In order to build up a comprehensive picture of each company, our analysts collect the information relevant to the rating both from the companies being analysed and from independent experts. During the rating process, considerable importance is attached to cooperating extensively with the company under evaluation. The companies regularly have the opportunity to comment on and add to the findings. The work of oekom research’s analysts is supported by a network of international experts from the fields of sustainability, human rights, employment rights and consumer protection:
Evaluation of company documentation such as annual and sustainability reports
Interviews with company representatives
Interviews with independent experts
Assessments from independent specialists from NGO's governmental and public institutions, business associations, research institutes, consumer protection groups etc.
