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

The actual certification process starts with the self-evaluation of the company 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, and are answered as the current status in the SPA is.

To fill in the GreenSign SPA tool, we recommend that you look at the marked mandatory criteria beforehand and look for the relevant documents. You must provide evidence of these at the latest for the audit.

They include eight core areas for sustainable management:

  • Management and communication
  • Environment (energy, water and waste)
  • Biodiversity and cultural heritage

  • Purchasing
  • Regionality and mobility
  • Quality management and sustainable development
  • Social responsibility
  • Economic responsibility

The assessment is based on a weighting factor and the fulfillment of international frameworks for the respective indicators.

The classification of the sustainability performance of your company is based on the result of the completed certification tool in GreenSign SPA Level 1 to GreenSign SPA Level 5.

The first steps towards fulfilling the sustainability concept have already been achieved in the SPA (up to 19%).

A well-founded focus on sustainability can be seen in the spa (up to 39%).

A sustainability concept is implemented and lived in almost all SPA areas (up to 59%).

The requirements for sustainable management are met to a high degree by the SPA (up to 79%).

The sustainability concept in the SPA is a role model and the best possible orientation (more than 80%).

3. Audit and award of the GreenSign SPA

All SPAs then undergo an examination by an independent expert in the form of an on-site audit and receive a qualified report - the sustainability declaration with helpful tips on the potential for improvement in sustainability performance.

After a successful certification process, InfraCert awards the GreenSign SPA sustainability certificate at the level achieved. A further development of the company to the next higher level can take place at any time and requires a separate audit.

The certification takes place for three years and enables transparent documentation and credible communication of the sustainability performance for the period. GreenSign SPA supports thermal baths, bathing and wellness landscapes in the further expansion of the sustainable orientation.
