We’re excited to announce the return of the Power 30 Most Sustainable Agencies initiative in partnership with event:decision for a second consecutive year.

Following the success of the inaugural campaign, applications are now open for 2025-26, giving agencies the opportunity to once again be included in a definitive list of the most sustainable event agencies in the UK market.

As with last year, agencies will be 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.

“We’re thrilled to be partnering with event:decision again to shine the spotlight on the UK agencies that are leading the way in that lead the way in sustainable event management. We hope to widen the net this year and encourage more agencies to take part in the initiative,” said micebook editor Susie Harwood.

Matt Grey, event:decision director, added: “It’s great to see the agency community working hard to demonstrate more responsible accreditations and delivery for client’s events. It’s clear that agencies have identified sustainable and responsible delivery to be a clear differentiator when it comes to winning and retaining business – ultimately delivering a better product.”

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.

The deadline for applications is 19 September, and the Power 30 Most Sustainable Agencies 2025–26 will be revealed at micebook EXPO on 2-3 February at Convene Sancroft.
