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

After registration in the certification tool, the independent self-evaluation of your gastro takes place. The criteria of the test catalog are based on the global sustainability goals defined by the United Nations, the SDGs. Together with the international frameworks ISO 14001 (environmental management), ISO 26000 (corporate social responsibility) and EMAS, this results in a comprehensive questionnaire that analyzes the current status of your company.

3. Audit and award with GreenSign Gastro

All catering establishments are then inspected during an on-site audit. The auditor requests previously announced documents as well as various verifications. The audit ends with a qualified audit report that reflects the company’s sustainability performance. The certification is valid for three years and enables transparent documentation and authentic communication of the company’s sustainable commitment for this period. Subsequently, the sustainable measures are reviewed and evaluated again on the basis of the eight core areas.

Purchasing and food offer

Purchasing is a central control organ, especially in the catering industry, and therefore an indicator of sustainable responsibility. The strategic and conscious selection of products supports climate and resource protection, animal welfare and humane working conditions. When selecting products, particular attention should be paid to quality and sustainability characteristics.

Social responsibility
