All establishments shall undergo audits as part of the Green Key application process, conducted by a third party auditor. On-site audits are carried out as minimum in year 1 (before receiving the certificate), year 2 and thereafter every third year.
The primary objective of the audit is to confirm compliance with the Green Key criteria through on-site inspections and document reviews. Additionally, the audit serves to educate about Green Key and FEE, and to offer guidance and share best practices. During the years, when there are no on-site audits, an off-site audit (document evaluation) is carried out.
