Green Events Hamburg is an open, participatory and future-orientated network that is dedicated to ecological, socially responsible events. Since 2019, the network has advised companies on how to achieve that goal on behalf of the Ministry for Environment, Climate, Energy and Agriculture in Hamburg. "We would like all events held in public spaces to actually benefit those areas." To this end, Green Events Hamburg has developed guidelines for holding sustainable events. "This year, a pilot phase was due to start with 23 event organizers, who tested our guide and from which we would have developed a point system for events in public spaces." But then corona hit, and the pandemic forced the cancellation of most events. Green Events Hamburg eventually extended the pilot phase until 2021.
