As regulatory requirements tighten and sustainability expectations rise, forward-thinking event teams are discovering that carbon measurement isn’t just about compliance—it’s driving real business value with 15-25% cost reductions through strategic optimization. The event planners who build these measurement capabilities now will have a significant competitive advantage as the industry shifts toward mandatory sustainability reporting.
