ISO 20121 Global Register

The Sustainable Event Alliance has created a Global ISO 20121 Registry for all organisations, events and venues claiming conformity to ISO 20121. The register allows those that have undertaken a conformity assessment to log their details including scope of management system, date, audit level achieved,  auditing body competency,  and  to upload a casestudy or other information to share with industry peers.
