WE FORMALIZE WHAT YOU ALREADY DO
We'll write the procedures to make your events sustainable. We'll take care of the rest.
Choosing local suppliers, on-site waste management, and venue energy consumption: your company already manages these aspects every time you organize an event. We map them, identify the requirements of the ISO 20121 standard, and build the event sustainability management system.
Work without surprises
Your Sustainability Management System monitored every day, not just in audits.
The ISO 20121 certification journey doesn't end on the day of the audit: it requires demonstrating sustainability at every new event you organize, with periodic surveillance audits. The platform monitors suppliers, consumption, and sustainability objectives event by event, and flags any non-conformities before they become a problem upon renewal.

Prepare to grow
Maintain access to sponsors and grants, event after event.
Sponsors, public bodies, and major clients verify certification with each new edition, not just the first time. The platform keeps your ISO 20121 compliance up to date, and if you also manage quality, environment, or safety with ISO 9001, 14001, or 45001, your Lead Auditor keeps everything aligned on the same system, so access to sponsors and tenders remains open over time, without having to manage parallel systems.

OFTEN COMBINED
Start from 20121, build the complete management system.
Those who already have ISO 20121 have an advantage over other standards: same structure, same Lead Auditor, same platform.
ISO 20121 cost and timelines
ISO 20121 certification: cost and timelines.
The cost and timelines of ISO 20121 certification depend on a few key factors. Here is what drives them, and how Complaion makes the whole path faster and more predictable.
Cost
ISO 20121 certification cost
There is no single answer to how much ISO 20121 certification costs. The ISO 20121 cost varies with the number of employees, sites and processes in scope, the number and type of events managed, and what is already in place. Complaion starts with a free analysis and then sends a tailored quote, with no surprises along the way.
Timelines
ISO 20121 certification timelines
The ISO 20121 certification timeline depends on your organization: employees, sites and processes in scope, the sustainability practices already applied to events, and the maturity of what already exists. With Complaion, how long ISO 20121 takes changes radically: the Lead Auditor and platform work in parallel, cutting timelines to a few months, or even weeks, without cutting corners.
FREQUENTLY ASKED QUESTIONS
Do you have any questions about ISO 20121 or how Complaion can help you?
What is ISO 20121 and why is it important for my company?
ISO 20121 is the international standard for sustainable event management: it covers the environmental, social, and economic impact of every event you organize, from supplier selection to on-site waste management. This is important because sponsors, public bodies, and large clients are increasingly selecting certified organizers, especially for events funded by public funds or linked to green tenders.
How can you help my company achieve ISO 20121 certification?
A Lead Auditor maps how you currently manage suppliers, consumption, and waste at your events, identifies regulatory requirements, and works with you to develop your event sustainability management system. The platform generates documentation and monitors objectives and deadlines event by event.
How long does it usually take to get ISO 20121 certified with Complaion?
It depends on the number and frequency of events you organize, and how well structured your sustainability practices are. Your Lead Auditor will give you a precise estimate after the initial analysis.
What kind of support does Complaion offer during the ISO 20121 certification process?
A dedicated Lead Auditor oversees every critical phase, from gap analysis to audit preparation, while the platform automates documentation and monitors suppliers, consumption, and sustainability objectives for each new edition of the event.
