Operational guidance
01
Define dates, venue, delivery format, attendance and calculation boundaries. Ask the venue and key suppliers which actual activity records they can provide.
02
Calculate a baseline, identify the largest sources, record reduction actions and open attendee travel collection early enough to improve coverage.
03
Replace estimates with actual venue, catering, material, freight and waste records. Reconcile attendee submissions and recalculate.
04
Confirm the residual footprint after reductions, review eligible project records and allocate the required quantity.
05
Retain purchase, allocation and retirement evidence. Generate a new report version and publish only the approved event status.
Working checklist
Create the event, calculate emissions, plan reductions and maintain a documented path from residual emissions to retirement.
