T02SUSTAINABILITY CRITERION
Travel
Measure travel associated with the event using a declared traveller boundary, activity data and versioned emission factors.
Event travel emissions intensity
kgCO₂e / attendee
Traveller groups, origin bands, mode, distance, vehicle occupancy, attendance, emission-factor set.
Σ(trips × distance × occupancy adjustment × emission factor) ÷ attendees.05 · TARGET
Good / Better / Best
Use the threshold as an assessment reference. If an event adopts a different threshold, publish it before measurement and keep it stable for comparison.
GOOD≥70% trip coverage
BETTER≥85% trip coverage + mode split target
BEST≥90% coverage + verified year-on-year reduction
Minimum evidence
Survey extract; ticket/transport data; factor table and version; boundary note; calculation workbook.
Without source data, the criterion score is capped at 40/100.
Pre-publication check
- ✓Traveller groups are defined before calculation
- ✓Return trips and multi-purpose trips have a stated rule
- ✓Survey coverage is reported
- ✓Emission-factor source and year are named
- ✓Raw origin/mode data are retained
