The Standard provides guidance on how to implement an event sustainability management system through process management; it is really about managing an event, or aspects of an event through a series of processes that aim to achieve the sustainability objectives of your event.
The Standard can be first, second or third party certified. The event organiser can claim that they have complied with the Standards. The event, or aspects of it, can be audited by a second or third party. A second party may be one of your suppliers or stakeholders and a third party is when you pay an accredited auditing company to audit and certify that your event complies with the requirements of the Standard.
