Green Key is a voluntary eco-label for hotels and hostels, campsites, holiday parks, small accommodations as well as conference centres, attractions and restaurants. The Green Key award is based on compliance with strict criteria with the areas of environmental management (water, energy, waste, cleaning, etc.) and sustainability education (staff, guests, suppliers, etc.). Compliance with the criteria are confirmed through a rigorous application process and verified at onsite audits. The award is valid for one year at a time. Currently, more than 2,350 establishments in more than 50 countries are awarded with the Green Key. The programme is managed by the international charity, the Foundation for Environmental Education. Green Key is endorsed by the World Tourism Organization and recognised by Global Sustainable Tourism Council. www.greenkey.global
