The key to sustainable tourism and hospitality
More than 9,000 hotels and other establishments in 90+ countries are Green Key certified as of August 2026
Green Key is an international sustainability certification programme for tourism establishments. The certificate is awarded to establishments that have been assessed against Green Key’s published criteria, developed by the Foundation for Environmental Education (FEE) in consultation with external relevant stakeholders. The criteria cover various areas including environmental practices, social responsibility, sustainability education and operational management.
The assessment process includes a review of documented evidence and an on-site audit based on a representative sample of evidence to determine whether the establishment meets the applicable criteria at the time of assessment. Regular assessments and periodic renewal requirements encourage continuous improvement in the areas covered by the programme.
Green Key is available to hotels, hostels, small accommodations, campsites, holiday parks, conference centres, restaurants, and attractions.
