Sustainability extends economic thinking and the associated responsibility to include ecological, social, societal and ethical aspects. Among other things, we strive for sustainable and cost-efficient solutions from procurement to disposal that are compatible with the environment and society as part of a Sustainable Supply Chain. To this end, we have implemented a holistic environmental management system that is certified in accordance with DIN EN ISO 14001:2015.

These guidelines provide the framework for the conduct that Seminaris Hotels expects of itself as well as contractual partners, suppliers, cooperation partners and third-party companies in the supply chain.



We culture

Together with our guests and partners, we form a strong team that achieves more for the well-being of all. We attach great importance to constructive cooperation. We act at eye level.


We question all processes and fully exploit the opportunities for environmental and climate protection in the hotel industry. Since 2019, the entire Seminaris hotel group has operated a certified environmental management system in accordance with DIN EN ISO 14001:2015.

Green Meetings

Sustainable conferences, workshops and meetings are a matter of course with us: for example, events run on green electricity and the buffet is plastic-free.


Among other things, we expect our suppliers to always pay attention to safety, avoid conflicts of interest, comply with the law and treat others with respect and dignity.
