Think about ways that you, as the organisers, might influence transport choices to and from the event. Study the transport options and share information with participants about how to emit the fewest CO2 emissions in the easiest way possible. Always encourage the use of public transport.
You can set targets for transport, e.g. CO2 emissions per participant or percentage who travel by train. The participants are not obliged to accept your suggestions or to inform you of their choices, but telling them about your targets and the transport options may have a positive influence on what they opt to do. Remember to make it clear that the information will be processed anonymously.
If the venue is not centrally located or near a transport hub, you can offer a shuttle bus that runs on electricity or biogas.
When transporting materials, demand environmentally-friendly delivery and CO2 reporting. Send as few materials and in as few shipments as possible.
When booking transport for participants, ask for their full name, date of birth or ID number and other needs, e.g. restrictions on means of transport, accessibility considerations, extra seat or baggage, early or late arrival. Process personal data securely and delete it afterwards. This makes participants with special needs feel safe, and they do not have to worry or feel they are being difficult.
