At PINO Switzerland – Professional International Norms Organization College – our mission is to support organizations that aim for excellence through meaningful, voluntary standards. One of the most important topics we’re seeing this week in our inspections and client consultations is the rising interest in ISO 20121, the international standard for Sustainable Event Management.
In today’s world, events are more than just moments of celebration or business gatherings—they are platforms with real environmental, social, and economic impacts. Whether it’s a corporate conference, a cultural festival, or a trade exhibition, the way an event is planned and delivered can make a big difference. That’s why ISO 20121 is gaining more attention—it helps organizers embed sustainability into every stage of their events, from concept to cleanup.
What is ISO 20121, and Why Does It Matter?
ISO 20121 is not just about being “green.” It’s about smart planning, responsible decisions, and future-focused leadership. The standard gives organizations a practical management system to identify and reduce the negative impacts of events while enhancing the positive ones. This includes reducing waste, cutting energy use, improving accessibility, involving local communities, and creating a lasting legacy.
The best part? ISO 20121 is flexible. It can be applied to events of all sizes and types. It doesn’t prescribe fixed steps; instead, it encourages each organization to set its own sustainability goals and work toward them in a structured, measurable way.
This week, our inspection team has seen a noticeable increase in pre-certification assessments related to ISO 20121. More and more event planners are reaching out, recognizing the value this framework brings—not only for the environment but also for their reputation, stakeholder trust, and long-term savings.
How Events Are Changing for the Better
We’ve observed that certified events tend to be more efficient, inclusive, and future-ready. For example, they often replace paper programs with mobile apps, choose venues with renewable energy, offer plant-based catering options, reduce unnecessary packaging, and provide access for people with disabilities. They also actively involve suppliers, staff, volunteers, and attendees in the sustainability journey.
These are not just trends—they are becoming expectations. Guests are increasingly drawn to events that reflect their values, and ISO 20121 provides a clear signal that an organizer is taking sustainability seriously.
The Role of PINO Switzerland
As a private, independent inspection body, PINO Switzerland is proud to support voluntary certification for ISO 20121. We operate with full neutrality, offering professional audits that help organizations assess and improve their sustainability practices. Our audits are based on international norms, but our approach is always personal and constructive.
We don’t act as a regulatory authority. Instead, we work side by side with clients, providing honest feedback and clear recommendations. Our goal is to guide each organization through a journey of improvement—not just to issue certificates, but to foster real change.
This Week’s Momentum
In our most recent fieldwork, we reviewed sustainability management systems for upcoming events across various sectors. Many of these organizers are seeking ISO 20121 recognition not because they have to, but because they want to lead by example. One of our inspectors described a current client’s effort as “a perfect blend of ambition and responsibility,” with innovative solutions being built into every part of the planning process.
While we keep client information confidential, we can say this: the shift toward sustainable event management is no longer niche—it’s becoming the new normal.
Looking Ahead
ISO 20121 is more than a certificate—it’s a commitment. It shows that an event is thoughtfully planned, respectfully delivered, and positively remembered. At PINO Switzerland, we’re proud to help organizations make this vision a reality. As the events industry evolves, so must the standards that guide it—and ISO 20121 is leading the way.
