Responsible use of resources
We believe that every company, regardless of the industry, has a social responsibility to act in an environmentally, socially, and economically sustainable manner.
Sustainability is an overused term these days, but we still choose to embrace it. All employees should pay close attention to the efficient use of all resources. We are proud of our Green Sign 4 certification for all our establishments. However, more important than certifications is our responsible approach to resource management.
At HARBR., we take these principles to heart every day and continuously seek sustainable alternatives wherever possible.
GreenSign Level 4


The sustainable efforts and quality strategy of our HARBR. hotels are showing initial successes and were rewarded with the GreenSign Level 4 certification in January 2024.
The GreenSign sustainability certification is awarded by GreenSign Institut GmbH in Berlin. It is a recognized certification catalog for determining the level of sustainability of a hotel, developed by the globally renowned Global Sustainable Tourism Council. The certification is divided into five levels, which indicate how many of the certification criteria a hotel meets.
