A standard that validates your responsible approach to events
Responsibility towards the planet and the community is now the standard. While sustainable event management is already common worldwide, Croatia is only just catching up. That’s why we developed the Green Leaf Excellence (GLE) certificates—to fill the gap and drive change.
GLE certificates help event organizers and venue owners demonstrate their commitment to sustainable practices, reduce negative impact, increase positive outcomes, and optimize costs in the process.
By obtaining a GLE certificate, you're not just formally confirming your commitment to sustainability—you're gaining a series of strategic advantages:
Our certificates are intended for anyone striving for excellence and responsibility in the event industry:
Event Organisers: Agencies and internal teams looking to certify their events
Companies: Validate the sustainability of your internal and external corporate events in line with ESG goals
Venue and Accommodation Owners: Those who want to position their spaces as sustainable and attractive
Schedule a preliminary meeting with the Eventful team to help us understand your goals and your event/venue's existing concept
Our certified EEE Event Managers will visit the venue or analyse the event concept. We'll create documentation and an evaluation of your current state of sustainability, along with specific recommendations for improvement
Based on the recommendations you receive, you'll work on implementing the sustainable criteria and practices
You'll submit your finalised documentation (for an event) or an application that meets the requirements (for a venue) to our Sustainability Decision Committee, which will also conduct an on-site inspection
The Sustainable Events Committee makes the final decision. Upon fulfilling all conditions and receiving a positive resolution, the Green Leaf Excellence certificate is issued
For certified venues, an annual review of the criteria is conducted to ensure continuous compliance
