Energy & water
Monitor consumption, reduce waste and consider solutions suited to each building when replacements are needed.
Thoughtful hospitality
With tomorrow in mind.
Hospitality also means caring for the places where we welcome our guests. At each hotel, we look at ways to use energy, water and materials more wisely and to consider local sourcing.

People & place
Involve our teams, consider local suppliers and help guests make informed choices.
Green Key
What is Green Key?
Green Key is an international sustainability certification for tourism establishments. It assesses individual properties against criteria covering management, energy, water, waste, purchasing and awareness. Certification is awarded after assessment to an individual property and requires renewal.
About certification
This page describes our ambitions and the Green Key framework. It does not confirm Green Key certification for the group or for each of our hotels. We communicate a current certification only for a property to which it has officially been awarded.
