Sustainable Hybrid Congress London - Carbon Neutral AGM for 450 Members
Date
May 2025
Location
London
Transformed a leading professional association's Annual Congress and AGM into a cutting-edge hybrid event that achieved carbon neutrality while engaging 450 members across 12 countries. Through innovative sustainable technology integration, local speaker partnerships, and comprehensive digital solutions, we delivered a 72% reduction in carbon footprint compared to traditional in-person events. The hybrid format increased international participation by 35% while maintaining high engagement levels and achieving zero waste certification for the London venue.
