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.
More than 4,000 establishments in 60 countries are 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.
The Green Key programme is managed by the international charity, the Foundation for Environmental Education (FEE) and its national member organisations.
Planting trees together, shaping the future

We’re in – for one million trees
With our dripdrop certification, we are making a clear statement for sustainability. For every project we implement together, a tree is planted – locally, transparently, and with real impact.
The initiative “OneMillionTrees” aims to plant one million trees worldwide and thereby contribute to climate and environmental protection. We are proud to be part of this movement and to make the world a little greener together with our customers.
