2. Complete the certification catalog

The certification process starts with a self-evaluation of the hotel, which takes place by filling out the certification catalog.

The 92 criteria of the test catalog were based on internationally recognized frameworks for sustainability such as ISO 14001 (EMAS / environmental management), ISO 26000 (Corporate Social Responsibility (CSR)) and the Global Sustainable Tourism Criteria (Sustainable Tourism (GSTC)), developed for the hotel industry.

The criteria include seven core areas for sustainable management:

  • Management and communication

  • Environment (energy, water and waste)

  • Purchasing

  • Regionality and mobility

  • Quality management and sustainable development

  • Social responsibility

  • Economic responsibility

All questions in the catalog are to be answered within about 4 weeks. In order to fill out the catalog, it is advisable to look at the marked mandatory criteria beforehand, which you have to prove during the audit, and to prepare the relevant documents.

3. Evaluation of the results by InfraCert

Based on the number of points, the sustainability performance is classified in GreenSign Level 1 to GreenSign Level 5.

For the classification with Level 1, at least 19 percent of the criteria within the seven core areas must be met. The highest award with GreenSign Level 5 requires a sustainability performance of over 90 percent.

The first steps towards fulfilling the sustainability concept have already been achieved in the hotel.

A well-founded focus on sustainability can be seen in the hotel.

The sustainability concept is implemented and lived in almost all hotel areas.

The requirements for sustainable management are met to a large extent by the hotel.

The sustainability concept in the hotel is a role model and the best possible objective.

4. Audit and award with GreenSign

All hotels undergo an on-site inspection by an independent expert (audit). The auditor requests the mandatory documents as well as various evidence. The hotelier receives an overview of the required documents in advance.

The audit ends with a qualified report, a so-called sustainability declaration. The certification takes place for three years and enables transparent documentation and credible communication of the sustainability performance for the period.

An interim audit is planned for each of the two following years of certification. The basis for this is a program of measures individually determined by the hotel at the beginning of the certification process, which shows defined sustainability aspects within the seven core areas with their objectives in the hotel.

After a successful certification process, InfraCert awards the GreenSign sustainability certificate at the achieved level. The certification shows possible weak points and potentials for improving sustainability performance. A further development of the hotel to the next higher level can take place at any time. The reclassification and verification require a separate audit.

Now, in addition to creating an action plan to expand sustainability measures, the focus can finally be placed on “green” marketing. InfraCert supports you in achieving a better perception of your hotel among guests, new target groups and stakeholders.
