Green Key is built on verifiable standards that cover responsible water and energy management, waste separation and reduction, the use of environmentally preferable products, and ongoing education for employees and guests. For the hotel, the certification is therefore not only recognition of its achievements to date, but also a commitment to continual improvement.

Sustainability as part of the hotel experience
The hotel encourages guests to make considered choices throughout their stay, including reusing towels and bed linen, conserving water, switching off lights and air conditioning when leaving their rooms, separating waste and choosing more sustainable forms of transport. Its culinary offering also emphasises seasonal and locally sourced ingredients.
The Green Key environmental certification complements the hotel’s broader commitment to sustainability. Four Points by Sheraton Ljubljana Mons is also the first hotel in Slovenia to obtain BREEAM In Use certification. The hotel generates part of its energy through its own solar power plant, operates its own heat pump and provides guests with numerous charging points for electric vehicles.
By obtaining Green Key certification, the hotel continues its development towards a model of responsible hospitality in which guest comfort, service quality and environmental stewardship complement one another.
