GreenSign Certificate

Hamburg, 31 August 2022

Our great commitment to ecological, economic and social sustainability has proven successful.

From now on, the Empire Riverside Hotel at Hamburg's harbour belongs to the certified GreenSign Hotels and has been awarded Level 4 out of 5 for its sustainability.

At a sustainability event, our General Manager Enrico Ungermann got to know the GreenSign team and they exchanged information about the current status of our hotel, successfully implemented projects, challenges and goals.

After a comparison with other providers who could support us on our way to becoming an even more sustainable company, we finally decided on GreenSign. In addition, GreenSign has also recently reached a huge milestone - the seal has been recognised by the international Global Sustainable Tourism Council (GSTC) and is now also looking forward to the international expansion of the seal.

„The international recognition by the GSTC Board was a very big and important milestone for us. We are very proud of this and are now optimistic about the international expansion of our GreenSign. Many large international hotel groups are already waiting for us and we are well prepared.”
