Is your organisation concerned?
Your organisation could consider ISO 20121 certification if:
You organise or manage events, whether one-off or recurring, such as conferences, trade shows, festivals, seminars, sporting or cultural events
Your clients, partners or institutions expect concrete evidence of responsible event management
You respond to public or private tenders requiring a sustainable event approach
Your activity involves a reception venue, a public-facing site, or an event-related service such as catering, logistics, stands or audiovisual production
Organisations concerned range from event agencies to local authorities, associations and reception venues. There is no size or sector requirement, the standard applies to any organisation involved in designing, organising or delivering events.
Our structured approach
Phase 1: Diagnostic and scoping
Before starting the process, we assess:
- Your level of maturity against the standard's requirements
- What still needs to be implemented to achieve certification
- Kick-off meeting, training on the standard and project scoping
Objective: get a complete overview and start off on the right track.
Phase 2: Action plan
We define:
- The priority actions needed to meet the standard's requirements
- The responsibilities and implementation timeline
- The resources required, on both your side and ESGlogic's
Objective: have a clear, validated roadmap before deployment.
Phase 3: Operational deployment
We translate the action plan into concrete initiatives:
- Raising awareness and training teams on the standard's requirements
- Drafting the required formal documentation, procedures, policies and records
- Implementing the necessary actions, processes and tools on the ground
Objective: meet all the standard's requirements ahead of certification.
Phase 4: Audit and certification
We support you through to official certification:
- Preparation for the internal audit, carried out by an ESGlogic partner, and correction of non-conformities
- External audit and certification, issued by a recognised third-party body
Objective: achieve formal recognition and public credibility.
