Events are often treated as one-off projects with sustainability addressed through isolated gestures, such as using recycled signage or offering a vegetarian menu option, rather than a structured approach applied across the entire event lifecycle. This **piecemeal approach** makes it difficult to demonstrate genuine sustainability performance or improve consistently from one event to the next. ISO 20121 addresses this gap by requiring organizations to embed sustainability considerations into every stage of event planning, from supplier selection to venue choice to post-event evaluation, rather than treating it as a marketing add-on. > **Tip:** Review your last major event and identify whether sustainability decisions were made systematically or only where convenient. Assess ISO 20121 for Your Events * * * ## **What ISO 20121 actually requires?** **Clause** **Requirement** Clause 4 Organizational context, stakeholder identification and event sustainability scope Clause 5 Leadership commitment and sustainable event policy Clause 6 Sustainability objectives, risk assessment and opportunity identification Clause 7 Resources, competence, supplier engagement and documented information Clause 8 Operational planning and control across the event lifecycle Clause 9 Performance monitoring, internal audit and management review Clause 10 Nonconformity, corrective action and continual improvement A distinguishing feature of ISO 20121 is its **strong emphasis** on stakeholder engagement and supply chain management, since events typically involve numerous third parties such as venues, caterers, contractors and transport providers whose practices directly affect overall sustainability outcomes. The standard requires organizations to identify these stakeholders early and set **clear sustainability expectations** for them, rather than only controlling what happens within the organizing team itself. * * * ## **Who should implement ISO 20121?** **Organization type** **Why ISO 20121 applies** Event management companies Core service offering benefits from demonstrable sustainability credentials Sporting event organizers High public visibility and scrutiny of environmental and social impact Conference and exhibition venues Repeated events benefit from a standardized sustainability system Corporate event and marketing teams Brand reputation increasingly tied to sustainability performance Festival and cultural event organizers Large temporary gatherings with significant local environmental impact Government and public sector event bodies Accountability for public funding and community impact Sporting and cultural events with high public visibility have driven much of the early adoption of ISO 20121, largely because the **London 2012 Olympics** used the standard as part of its sustainability commitments, demonstrating its practical application at a major international scale. Since then, corporate event teams and conference organizers have **increasingly adopted** it as client and stakeholder expectations around sustainability have grown across the events industry. > **Takeaway:** ISO 20121 is valuable across the full spectrum of event types, not just large-scale international events. Check ISO 20121 Applicability for Your Organization * * * ## **Core areas Auditors assess** **Focus area** **Examples of evidence assessed** Stakeholder engagement Documented consultation with local communities, suppliers and attendees Supply chain management Supplier sustainability criteria, contracts and monitoring records Resource and waste management Waste reduction targets, energy use tracking, water conservation measures Social impact Accessibility provisions, local employment, community benefit initiatives Legacy planning Post-event evaluation and plans for reusing materials or infrastructure Auditors typically look for evidence that **sustainability objectives** were set before the event, tracked during delivery and evaluated afterward, creating a genuine feedback loop for improvement. A common gap identified during audits is organizations that produce sustainability policies and post-event reports but cannot demonstrate that objectives were **actually monitored** or that lessons learned were applied to subsequent events. > **Writer's view:** Set measurable sustainability targets before your next event, not just aspirational statements and track them throughout delivery. * * * ## **The ISO 20121 certification process** - **Stage 1 audit:** Reviews the sustainable event policy, stakeholder analysis, risk assessment and planning documentation - **Stage 2 audit:** Verifies operational implementation through on-site observation, supplier records and post-event evaluation - **Certificate issuance:** ISO 20121 certificate issued upon successful Stage 2 completion, valid for three years - **Surveillance audits:** Annual audits confirm continued operation of the sustainability management system across subsequent events - **Recertification:** Full recertification audit conducted at the end of the three-year cycle - **Typical timeline:** 3 to 6 months for organizations with existing sustainability practices; 6 to 9 months for organizations building a system from scratch Organizations running one-off events face a particular scheduling challenge, since Stage 2 evidence often needs to be gathered during the live event itself, requiring careful audit planning around the event calendar. Organizations running recurring events typically find certification easier to sustain over time, since the management system can be refined and reapplied across each subsequent edition. Request Your ISO 20121 Certification Audit Plan * * * ## **Why organizations invest in ISO 20121?** Certified organizations typically report improved resource efficiency, stronger stakeholder and community relationships, reduced waste and associated costs and enhanced brand reputation among **increasingly** sustainability-conscious attendees and sponsors. In competitive event bidding, particularly for major sporting events, government-funded events and large corporate conferences, certification can serve as a **differentiating credential** that demonstrates genuine sustainability commitment rather than surface-level marketing. * * * ## **Author's views** Events are temporary by nature, which makes it tempting to treat sustainability as a **one-time checklist** rather than a system that improves over successive events. The standard's requirement to embed sustainability into supplier selection, stakeholder engagement and post-event evaluation forces organizers to think beyond the event itself and consider the full lifecycle of impact. Organizations that implement ISO 20121 well use it to build institutional knowledge across their event portfolio, rather than starting from scratch each time. The most effective implementations treat **post-event evaluation** as a genuine feedback mechanism, feeding lessons learned directly into planning for the next event, so that sustainability performance compounds over time rather than resetting with every new event cycle.
