Van der Valk Hotel Haarlem is certified with the "Green Key Gold" quality mark.
The Green Key is the international quality mark for companies in the tourism and recreation sector that are verifiably engaged in the company's environmental care.
In order to qualify for the Green Key, entrepreneurs have to take many measures with regard to environmental care and CSR. These measures are partly mandatory, partly optional.
Green Key Netherlands has three levels: Bronze, Silver and Gold. The more optional measures an entrepreneur fills in, the higher the final result.
The Green Key guarantees the voluntary commitment of the entrepreneur to do more for the environment than the laws and regulations require of him. This is also a means of communicating the company's sustainable image to guests, governments and business relations.
After a thorough inspection by the 'Stichting Keurmerk Milieu', Safety and Quality, the golden certificate of the Green Key has been extended year on year since 7 May 2013.
