We take responsibility
Admiral Hotel is a member of the international environmental organization Green Key and follows the established criteria for energy consumption, waste sorting, environmentally responsible purchasing, and sustainable resource use.
Admiral Hotel is also certified with the Nordic Swan Ecolabel.
This certification confirms the hotel’s commitment to sustainable operations and to creating a healthy and responsible environment for both guests and employees. The Nordic Swan Ecolabel also requires continuous improvements, meaning that Admiral Hotel consistently works to optimize its processes.

Furthermore, as a member of the professional business organization Dansk Erhverv, we respect and comply with requirements regarding wages, benefits, and employment conditions, and we follow the UN Convention on Economic, Social and Cultural Rights, including the UN Sustainable Development Goals.
Help us, help the environment
In line with responsible hotel operations, the environment is something we think about and incorporate into our daily work. We are constantly working for a greener agenda, such as less less waste and less plastic as well as more recycling and securing resource use.
We continuously inform all our employees about how they best contribute and help take responsibility for a sustainable future. It is also important to us that you as a guest are informed about our sustainable initiatives and how you can contribute when you stay with us.

Waste sorting
Throughout the hotel – in the restaurant, on guest rooms, and in common areas – we sort our waste, and we kindly ask our guests to do the same where possible.
In your room, cans, plastic, and glass bottles can be placed next to the trash bin for easy sorting by housekeeping. Newspapers and clean paper should be placed in the marked compartment of the bin. The other compartment is for general mixed waste. Batteries can be dropped off at the reception, where we ensure proper recycling.
Our housekeeping team also takes care of additional sorting behind the scenes to maximize recycling.
The more we sort – the more we recycle
Help us sort your waste at the hotel and we will help with a more sustainable agenda. We sort the following ourselves:
Cardboard is sorted and compressed in cardboard presses for recycling.
Paper from our offices is collected in a separate container that is picked up for processing recycled paper.
Bottles are collected for recycling.
Glass and porcelain are sorted into separate containers and picked up for recycling, and used as a base in road pavement.
Food waste and other organic waste are collected and used for production.
Residual waste, the waste that is left over when everything else has been sorted out, is taken to an incineration plant, where the waste is converted into new energy.
Plastic and metal are sorted into separate containers and picked up at a recycling station.
Batteries, electronic waste and light sources are sorted and driven to a recycling station by our own employees.
Food waste and sustainable food
We are focussed on minimizing food waste as well as purchasing more sustainable food.
We portion our dishes and adjust according to the number of guests. We make sure to use seasonal and local Danish or European products and strive to always buy organic and eco-labeled products when possible.
There is less and less clean water – both in Denmark and in the rest of the world. New water-saving products and methods save more clean water.

Intelligent rooms
In connection with the renovation of our 366 rooms in 2019, intelligent control of heating, lighting and Aircool was installed. With new light types, control and measurement, we save energy throughout the building.
All rooms lights are automatically switched on and off via key cards, and there is dimming, night light and clock control in common areas as well as in the hotel’s outdoor area. Energy-saving LED bulbs are installed in all luminaires, lamps in rooms, in guest areas and in the restaurant.
Energy-efficient water use
We secure energy-efficient water use by using seawater for our AirCool system in our guest rooms. We took measures to reduce the hotel’s wastewater consumption through efficient water use by installing aerators in all taps and showers, which limits water consumption up to 50%.
Water consumption and water waste are further limited by the possibility of using small and large flushes in all toilets.
We cool down with water from the harbour
From October through May, when the seawater temperature is low, cooling is produced for the hotel’s rooms by drawing the cold seawater from the Copenhagen Harbour into the central cooling systems, via pipelines from HOFOR.
Using an exchanger, the cold water is used to cool the water in the hotel’s own systems, after which the water is sent back to HOFOR.
Dynamic change
As we are constantly becoming wiser about new initiatives and new ways of working more sustainably and environmentally friendly, we are constantly evolving.
