Events are becoming more sustainable by taking into account the location, the caterer and the building where the event is planned.
A location close to a central station has the benefits of public transportation as a sustainable transportation alternative. Also, less transportation is needed when you choose suppliers who have their business close to an event location. The same applies to the products of your caterer: products from a close distance and preferably vegetarian or vegan cause less emissions. Ask event organizers for the possibilities of organizing a sustainable event.
