Our Testimonials
More than 9,000 hotels and other establishments in 90+ countries are Green Key certified.
Green Key is an international sustainability certification programme for tourism establishments and hospitality businesses. The certificate represents a commitment by establishments to operate according to environmental and social sustainability criteria set by the Foundation for Environmental Education (FEE). A Green Key certificate signals that an establishment has undergone an assessment process, including an on-site audit, to verify conformity with the applicable criteria. The certification process is based on documented evidence, regular assessments, and periodic renewal requirements to support continuous improvement in environmental and sustainability practices. Green Key is available for hotels, hostels, small accommodations, campsites, holiday parks, conference centres, restaurants, and attractions.
