At registration, attendees are asked how they plan to travel to the event as well as their home postcode. This data allows the organiser to map the travel modes of all participants and calculate an estimate of the CO₂ impact generated by transport to and from the event.
Sustainability added value: You cannot reduce what you do not measure. By collecting travel data at the point of registration, the organiser gains a concrete, evidence-based picture of the event’s transport footprint — creating the foundation for informed decisions, targeted communication and continuous improvement in reducing mobility-related emissions at future editions.
