Green Key
Last update: August 2026
Our Testimonials
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.
New Criteria & Processes Explained
To support establishments during this transition period, Green Key International hosted a second round of online information sessions on Wednesday 19 August. These webinars covered an overview of the most important changes and introduced practical guidance on what is important for the application process. To support a smooth transition, the Green Key team will host a Q&A session focused on confidently navigating the updated certification requirements.
