No fewer than three Stage Venues locations were granted a Green Key. During the national presentation in Driebergen, the AFAS Circus Theatre The Hague, the Beatrix Theater Utrecht and the Amsterdam Convention Factory received the much-coveted Green Key from Mayor Naafs. The event locations received one golden and two silver Green Keys, respectively. The Green Key is the international eco-label for environmentally-conscious companies in the tourism and leisure industry.
