ESG ratings and rankings

Based on high-quality company data, ESG ratings often form the basis for sustainable investment strategies. We have been in close contact with the leading ESG rating agencies for years. Our goal is to achieve a fair and transparent assessment of our company. At the same time, through the comparison with other companies, we have also gained important information for the extension of our sustainability activities.

Through targeted and constructive dialogue, we have been able to make significant progress in recent years with what we consider to be the most important rating agencies. These include, among others, elimination of the respective MSCI and ISS-ESG red flags, an improved position in the Access to Medicine Index and a leading position in the Access to Seeds Index.

Here you will find an overview of the most important ratings for us:
