Every trading day the gong is sounded in Amsterdam to mark the opening (9.00 am) and closing (17.30 pm) of the trading session.
Marjan Minnesma, director of Urgenda, opened trading in Amsterdam in honour of Sustainability Day (Dag van de Duurzaamheid).
Urgenda, the organiser of the event, invites everyone to take part in the activities on 11-11. Sustainable activities and events will be held throughout the Netherlands on that day. In addition to Sustainability Day, Urgenda has launched the Ik Spring Over (I'm going sustainable) campaign to stimulate the development of concrete sustainable projects.
