Green Key was launched in Denmark in 1994 and has been managed by the Foundation for Environmental Education (FEE) and its national member organisations since 2002. With more than 6,000 certified business in over 70 countries, Green Key is the most widespread tourism certificate. Our hotels agree to comply with the strict FEE guidelines as part of this collaboration. The plan is for all 25hours Hotels to have obtained Green Key certification by the end of 2024. This will involve the launch of numerous initiatives in guest areas and in the background. Some of these measures include encouraging the use of tap water, reducing water consumption in the rooms, minimising food waste and social cooperation with local and national partners.
