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

The actual certification process begins with self-evaluation when filling out the certification tool. The more than 100 criteria of the SPA certification follow recognized frameworks such as ISO 14001, ISO 26000 and GSTC. The ACTUAL status of your SPA operation is evaluated in eight areas.

For an ambitious sustainability strategy at the corporate level, it is essential to consistently incorporate the “17 Sustainable Development Goals” (SDGs). Therefore, the GreenSign SPA criteria are largely based on the fields of action of the 17 goals.

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, GreenSign Level 5, requires a sustainability performance of over 90 percent.

3. Audit and award of GreenSign SPA

All SPAs then undergo an on-site inspection in the form of an audit. During the audit, the auditor requests the mandatory documents and various verifications. The SPA manager receives an overview of the required documents in advance.

The audit ends with a qualified audit report, which reflects the sustainability performance of the SPA business. 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.

SDG 6 (clean water and sanitation), SGD 7 (affordable and clean energy), SDG 12 (sustainable consumption/production), SDG 13 (climate action).

    Your added value?

    After a successful certification process, the GreenSign Institute awards the GreenSign SPA sustainability certificate at the level achieved. The certification shows possible weak points 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 SPA operation, sustainability measures will also be implemented in the future. We support your SPA in achieving a better perception among guests, new target groups and stakeholders.
