Green Key criteria


Educate: We put huge focus on informing and involving visitors in the measures being taken by an establishment towards being more environmentally friendly and sustainable. We are also ensuring that the staff operating at the establishment are well informed and trained in the fields of environmentally friendly and sustainable practices.

Innovate:Green Key is constantly searching for new and sustainable methods of operation and use of technology in a bid to reduce the overall environmental footprint through lower use of energy, water and waste. The change helps the establishments engaged in Green Key in saving costs.

Add value: Positive environmental credentials are becoming more and more important to travellers when they are trying to decide on a place to stay. Green Key symbolises a commitment to the environment and sustainable development which is extremely attractive to potential guests.
