Evidence is based on what you already use to run the event well, such as sustainability policies and management plans, supplier and vendor contracts, site layouts and operations plans, website or ticketing copy, email templates, training and briefing records, monitoring logs, metrics exports (for example meter reads, fuel logs, waste tickets, survey results), photos or videos, and post-event reports. You provide these as links to your existing cloud folders rather than uploading raw files, and as long as the evidence is legible, dated, clearly linked to the event, and mapped to the relevant credit, it can be used by our verifiers to confirm completion.
