TS ISO 20121

TS ISO 20121 sets out requirements, together with guidance for use, for an event sustainability management system covering any type of event or event-related activity. It is aimed at organizations that want to structure sustainability within event planning and delivery, helping them manage environmental, social and economic considerations in a systematic way across occasions such as conferences, exhibitions, sporting events, festivals or other public gatherings.

What the management-system model focuses on

The standard is concerned with the framework used to manage sustainability, not with prescribing a single sustainability outcome for every event. In practical terms, it aligns policy, objectives, responsibilities, operational control and continual improvement so that the organization can work consistently toward its stated sustainable development policy and intended results. In an event context, that typically means looking beyond the programme itself to related activities such as procurement, venue operations, logistics, attendee services and supplier coordination.

Conformity, use and practical context

The document also provides a basis for voluntary conformity claims through first-party self-declaration, second-party confirmation, or independent third-party assessment. In general technical terms, event sustainability management brings together disciplines that often sit apart in event delivery: resource use, waste prevention, community impact, accessibility, stakeholder engagement and supply-chain choices. A common system helps an organization define expectations, monitor progress and improve performance over time without limiting the standard to one event format or size.
