Green Key certification

Green Key is a seal of approval for companies in the recreation industry. Companies with a Green Key seal of approval are committed to sustainability. For example, they use solar panels, energy-saving light bulbs, light sensors and timers for air conditioning and heating. These companies meet the standards set by the KMVK Foundation (Stichting Keurmerk Milieu, Veiligheid en Kwaliteit).
