Green Key
The Green Key certification is based on compliance with strict internationally recognised criteria in the areas of environmental management (water, energy, waste, cleaning, etc.) and sustainability education (staff, guests, suppliers, etc.).
Compliance with the criteria is confirmed through a rigorous application process and third-party verified after regular on-site audits. The certification is valid for one year at a time.
Currently (May 2023), there are more than 4,000 establishments in 60 countries certified with the Green Key.
Green Key is endorsed by various institutional partners, international hotel chain and tour operator partners and cooperating with a range of web partners.Â
The Green Key programme is managed by the international charity, the Foundation for Environmental Education (FEE) and its national member organisations.
