In order to receive the certificate, the hotels must positively answer up to 90 percent of the total of 92 questions in accordance with the desired level. This is checked by an independent auditor on site before GreenSign Level 1 to 5 is awarded.
During the certification process, each hotel individually defines a targeted program of measures with clearly defined sustainability aspects of all seven core areas. This qualitative management system is therefore more than just an award, but has the constant development of the sustainability of the hotel as its goal.
The hotels certified with GreenSign meet the highest quality requirements for sustainable management. With the sustainability barometer on GreenLine-Hotels.com in the hotel view, you get a transparent overview of the actual sustainability of each hotel in the individual core areas.
Die GreenSign Zertifizierung muss alle 3 Jahre erneuert werden, was eine Steigerung des GreenSign Levels bei erhöhter Nachhaltigkeitsleistung ermöglicht.
Sustainably managed hotels that have been certified with one of the following recognized seals can also be booked on GreenLine-Hotels.com. We also accept these certificates because they consider the main criteria for sustainable hotel operations and thus grant a high standard in the review of sustainability performance.
