Calling all UK event agencies! Applications are open for the Power 30 Most Sustainable Agencies 2026-27 list – an annual ESG benchmarking initiative by micebook in partnership with event:decision.
Now in its third year, the Power 30 is designed to recognise the agencies leading the way on sustainability and social impact.
Agencies taking part are evaluated based on both sustainable internal business practices and the ability to deliver sustainable outcomes for client events.
Submissions are scored according to pre-published credentials rather than being subjectively judged, resulting in a qualified, scored, and benchmarked list of the best performers in sustainability, showcasing real capabilities and proof points for responsible events.
This year’s initiative is proudly supported by Worlds Better, a sustainability consultancy specialising in the events and experiential sector, and Olio, the food-sharing platform tackling food waste by redistributing surplus food to local communities.
Enter your agency now for the opportunity to be included. The deadline for applications is 30 October 2026 and the Power 30 2026-27 list will be revealed at micebook EXPO 2027. Winners will receive accreditation in the dedicated Power 30 publication and could also feature in a spotlight as a top scorer across several categories.
“Power 30 is designed to be a meaningful benchmark, one that celebrates progress, encourages transparency and raises standards across the sector,” said micebook editor Susie Harwood. “We’re excited to be partnering with event:decision for a third consecutive year on this important initiative.”
Matt Grey, event:decision director, added: “This has been a mixed year for event agencies, with cost, resource and time pressures compounded by geopolitical uncertainty, even as investment and acquisitions continue across the sector. Against this backdrop, sustainability is growing up.
“It’s no longer enough to have a policy on file or an accreditation on the wall. Clients, investors and regulators increasingly want proof of performance. The Power 30 recognises agencies that are turning sustainability into a commercial advantage by delivering better outcomes for both clients and the business.”
It costs £249 to enter and submissions are welcome from organisations who act as agencies within the event sector, including full-service agencies, logistics agencies, exhibition design & build agencies, creative agencies, production agencies and creative AV agencies.
