With its Sustainability Report on the 2015 financial year Hannover Rück SE is publishing information on social, environmental and governance topics within the Group for a fifth consecutive year. Our Sustainability Report was drawn up in accordance with the G4 Guidelines of the Global Reporting Initiative (GRI) as well as the G4 Sector Disclosures for the Financial Services industry. The report has been compiled in conformity with the "Core" option, which contains the essential elements of a sustainability report. Furthermore, with a view to satisfying the information requirements of our stakeholders and the rating agencies as comprehensively as possible, we are providing additional information (Link GRI Content Index). The reporting period is from 1 January to 31 December 2015. Significant developments in 2016 have been included up until the editorial deadline in October 2016. Unless otherwise indicated, the particulars refer to the entire Hannover Re Group.

The report was submitted for the GRI Materiality Disclosure Service and GRI has confirmed the correctness of the location of the G4 Materiality Disclosures (G4-17–G4-27).

The present Sustainability Report reflects the issues and challenges of sustainable development that are material to our company. It takes into account the requirements of stakeholders who are of major significance to Hannover Re. The fundamental principles on which the report is based are materiality, the inclusion of stakeholders, the sustainability context and comprehensiveness. A materiality analysis was carried out in 2014 in order to identify the issues most relevant to the company.

Survey methods and calculation bases for the data

Unless otherwise stated, we report on Hannover Re's activities Group-wide.

The stated environmental indicators refer to the Hannover location (degree of coverage: 52,1 % of worldwide workforce). We use data collected internally from various departments as well as consumption data contained in the bills received from our electricity and district heating supplier.

For the purpose of calculating our CO2 emissions from business travel we adopt the calculation methods of our offset provider "atmosfair" and of Deutsche Bahn AG. We establish the CO2 savings from the use of videoconferences by utilising data from our service provider "Tata Communications" as well as Hannover Re's own internal calculations and estimates made on this basis.

In order to make the report more easily readable we have avoided gender-specific duplications and instead used the masculine form throughout.
