30 of the 35 hotels belonging to DSR Hotel Holding (as at September 2026) are certified to the GreenSign Hotel Standard. Certification is granted to each individual hotel and relates to the version of the standard and the period of validity stated on the relevant certificate.
The certificate confirms that the establishment in question meets the requirements of the GreenSign Hotel Standard relevant to certification.
Compliance with the criteria is verified on the basis of supporting documentation and an on-site audit. The audit results are then examined in a separate review and form the basis for the certification decision.
