YESS is built for event professionals who are ready to move beyond buzzwords and take meaningful action toward a more sustainable future. This one-day summit will bring together venues, suppliers, planners, agencies, and advocates for a day of inspiring conversation, knowledge-sharing, and practical takeaways.
Attendees will explore a wide range of topics- from reducing environmental impact to designing inclusive experiences, addressing mental health and neurodiversity in event planning, and making sustainability measurable and manageable.
"We created YESS because we’re tired of talk without action," says Ben Vollans, Co-Founder of Your First. "It’s time to move past performative gestures and drive real, collaborative progress across the industry."
The programme has been curated to prioritise peer learning and open dialogue, with a mix of panel conversations, interactive workshops and a small exhibition area.
Among the day’s highlights is a special session hosted by Anna Abdelnoor, CEO & Founder of isla, who will launch the second edition of the Temperature Check Report—an industry-defining study now expanded to include European insights.
The Green Action Labs will explore food sustainability in both indoor and outdoor event contexts, inclusive and community-driven alternatives to traditional offsetting, and how to harness technology to reduce waste and improve sustainability performance. With a core emphasis on inclusivity and collaboration, the event encourages knowledge-sharing and honest discussion—recognising that real sustainability doesn’t happen in isolation.
