We are in contact with various environmental, social and governance (ESG) rating agencies as part of our sustainability activities and we participate in their rating processes on a regular basis. In so doing, we seek to ensure that the rating agencies are optimally placed to reach their evaluations based on robust information and in some areas additional data provided confidentially. At the same time, the questions and comments in the rating surveys give us important pointers for potential improvement. Our goal is to be listed in at least two recognised sustainability index families. In addition, we strive to continuously improve our ESG ratings results.



Since 2007, we have participated annually in the CDP rating process. The UK non-profit organisation CDP – formerly known as the Carbon Disclosure Project – collects transparency and climate protection data from 8,000 companies around the world every year. Our current rating: B (scale D- - A)


Since 2008, Hannover Re has been assessed by ISS-ESG. The Institutional Shareholder Services group of companies (“ISS”) empowers investors and companies to build for long-term and sustainable growth by providing high-quality data, analytics, and insight. Hannover Re has been rated with an overall ESG rating of C+ and decile rank 1 by ISS-ESG since February 2020. In September 2021, the rating was verified by ISS-ESG and our company awarded “prime status” for the seventh time in a row. We were also acknowledged for a very high transparency level.


We have been participating in the rating process since 2014. MSCI ESG Ratings aim to measure a company’s resilience to long-term, financially relevant ESG risks. In 2021, Hannover Re received a rating of A (on a scale of AAA-CCC) in the MSCI ESG Ratings assessment.


We have been assessed by Sustainalytics since 2014. Sustainalytics is a provider of ESG and Corporate Governance research and ratings. Hannover Re received a score of 17.9 and was assessed as a low risk in terms of major financial impacts based on ESG factors (March 2024).



In March 2020, Hannover Re was also included in the newly created sustainability index of Deutsche Börse, the DAX50 ESG.


FTSE Russell confirms that Hannover Re has been independently assessed according to the FTSE4Good criteria, and has satisfied the requirements to become a constituent of the FTSE4Good Index Series. Created by the global index provider FTSE Russell, the FTSE4Good Index Series is designed to measure the performance of companies demonstrating strong Environmental, Social and Governance (ESG) practices.
