The Global Reporting Initiative develops internationally recognised guidelines for sustainability reporting by incorporating a variety of stakeholders and is constantly adjusting these. The GRI is a partner to the United Nations Environment Programme.


HAMBORNER REIT AG has a long history of reporting on ESG and sustainability issues. The sustainability reports are an integral part of our sustainability management and provide non-financial information that supplements the respective annual reports. In preparing the reports, we are guided by the internationally recognised Sustainability Reporting Guidelines (Standards) of the Global Reporting Initiative (GRI). Other frames of reference for our sustainability management and external reporting are the Sustainability Best Practices Recommendations (sBPR) published by the European Public Real Estate Association (EPRA) and the Practical Guidelines for Effective Social Action of the German Property Federation (ZIA).

More information on this can be found in our sustainability report.
