Attendees who arrive by carpool with at least three people in the vehicle park for free. Those arriving with fewer than three occupants pay a €5 parking fee. This policy is clearly communicated in advance, encouraging attendees to coordinate shared travel before the event day.
Sustainability added value: By making the financial incentive concrete and immediate, the free parking policy turns carpooling from a good idea into an easy and rewarding choice. Reducing the number of single-occupancy vehicles travelling to the event directly lowers its transport-related carbon footprint — and clear advance communication ensures the measure reaches attendees early enough to influence their travel planning.
