Event Sustainability System
Defines a management system for planning, delivering, and improving events with environmental, social, and economic sustainability built into event decisions.

Measurable Event Legacy
Turns sustainability intentions into objectives, controls, performance monitoring, and continual improvement across the event lifecycle.

Who Needs to Comply?
Event owners, organizers, venues, sports bodies, conference operators, public-sector event teams, festivals, exhibitions, and suppliers that need a structured way to demonstrate sustainable event planning and delivery.
Key Requirements
Define the Event Scope
Set the boundaries of the event sustainability management system, including event types, sites, suppliers, interested parties, and activities under organizational control or influence.
Assess Sustainability Issues
Identify environmental, social, and economic impacts and risks such as waste, transport, accessibility, labor practices, community disruption, procurement, emissions, and legacy outcomes.
Control Suppliers and Venues
Translate sustainability objectives into procurement criteria, supplier requirements, venue controls, operational plans, and evidence expectations.
Monitor Performance
Measure progress against objectives, collect event evidence, review incidents and stakeholder feedback, and report performance in a form that supports accountability.
Improve the System
Use internal review, corrective actions, management review, and lessons learned to improve sustainability outcomes across future events.
Penalties & Enforcement
ISO 20121 is voluntary and has no direct statutory penalties. However, host-city requirements, sponsor commitments, public procurement rules, ESG promises, and venue contracts can make the standard commercially important; weak sustainability controls can create reputational, contractual, and permitting risk.
