Why Organize Sustainable Events?
In 2026, sustainability is no longer an option but an expectation. 78% of event participants state they prefer environmentally conscious organizations. Companies running sustainable events record +23% engagement and a better brand perception.
Additionally, European regulations are becoming increasingly stringent. The Plastic Tax, SUP directives (Single-Use Plastics), and ESG requirements for listed companies make the transition to sustainable events not only ethical but strategically necessary.
1. Planning and Strategy
- Define measurable sustainability goals (e.g. -50% plastic, carbon neutral)
- Appoint a Sustainability Manager for the event
- Allocate a dedicated sustainability budget (5-10% of total budget)
- Identify KPIs to monitor before, during, and after the event
- Choose a venue with environmental certifications (ISO 14001, EMAS)
- Plan sustainable communication to participants and sponsors
2. Materials and Setups
- Eliminate single-use plastic (cups, cutlery, plates, bottles)
- Use reusable or biodegradable setups
- Choose materials printed on FSC-certified paper
- Prefer useful and sustainable giveaways (no useless plastic)

3. Food & Beverage

4. Logistics and Transport
