ISO 20121: Event sustainability management systems

A certifiable system for planning and running more sustainable events.

ISO 20121 sets requirements for an event sustainability management system, from venues and organisers to suppliers. It is used for conferences, exhibitions and major sporting and cultural events.

Who it is for

  • Event organisers, venues and exhibition centres

What you gain

  • Credible sustainability claims for events

Your path to certification

  1. Gap assessment

    We compare what you do today with every requirement and control, then give you a prioritised gap report and a realistic timeline.

  2. Design and documentation

    Scope, policies, procedures, risk methodology and records, written to fit how your teams actually work, not a template binder.

  3. Implementation and training

    We help owners put controls in place, train the people who run them and start collecting evidence.

  4. Internal audit and management review

    An independent internal audit and a structured management review prove the system works before the certification body looks at it.

  5. Certification audit support

    We prepare you for Stage 1 and Stage 2 with your chosen accredited certification body and help close any findings quickly.

  6. Surveillance and continual improvement

    Optional managed support keeps evidence current through annual surveillance audits and the three-year recertification.
