2. Log in to the GreenSign tool & self-evaluation

After registration in the certification tool, the independent self-evaluation of your hotel takes place.

The more than 100 criteria of the eight areas of the test catalog were developed on the basis of internationally recognized frameworks for sustainability. These include ISO 14001 (EMAS/Environmental Management), ISO 26000 (Corporate Social Responsibility) and the Global Sustainable Tourism Criteria, which were developed by the GSTC for the hotel industry. Since 2022, the GreenSign Hotel Standard has also been officially recognized by the GSTC.

Within about 4 weeks, all questions will be answered in the online tool. To fill in the form, it is advisable to take a look at the marked obligatory criteria beforehand, which you have to prove at the latest for the audit, and to look for the corresponding documents. The classification of the sustainability performance is based on the number of points in GreenSign Level 1 to GreenSign Level 5. For a Level 1 rating, at least 19 percent of the criteria within the eight core areas must be met. The highest award of GreenSign Level 5 requires a sustainability performance of over 90 percent.

The audit ends with a qualified audit report that reflects the hotel’s sustainability performance. The certification takes place for three years and enables transparent documentation and authentic communication of the sustainable commitment for the period.

100 criteria. 8 areas. 3 pillars.
We explain them to you.
Management & Communication

Management and communication are central components of a sustainable corporate orientation. They stand for a system of values and responsible shaping of the future in dialog with stakeholders.


The environmental pillar comprises the ecological areas of energy, water and waste. As essential components and influencing factors on the ecological footprint, strategies and measures to reduce resource consumption are essential.

Biodiversity & Cultural Heritage

A biodiverse farm takes responsibility for the surrounding flora and fauna and does its part to protect and grow them.


Purchasing is a central control organ and indicator for sustainable management. Regional, seasonal, organic and fair-trade products are becoming increasingly important in society and the value chain in hotel purchasing.

Your added value?

After a successful certification process, the GreenSign Institute awards the GreenSign sustainability certificate at the achieved level. The certification highlights possible weaknesses and potentials for improving the sustainability performance. Recertification takes place after three years with a new on-site audit. With an environmental program on the part of the hotel, sustainability measures will also be implemented in the future. We support your hotel in achieving a better perception among guests, new target groups and stakeholders.
