Our award-winning streak continues in 2026 – we’re delighted to share we’ve earned a place on the micebook Power 30 Most Sustainable Agencies.

micebook and event:decision revealed the Power 30 Most Sustainable Agencies 2025-26 at the micebook EXPO this week, shining the spotlight on the agencies leading the way on ESG.

The list recognises 30 event agencies in the UK market, based both on their sustainable internal business practices and their ability to deliver sustainable outcomes for client events.

Matt Grey, director at event:decision said: “Benchmarking initiatives like the Power 30 Most Sustainable Agencies are about more than recognition. They enhance individual agency performance while contributing to the broader goal of creating a more sustainable event sector.

“By encouraging collaboration and knowledge-sharing, this campaign empowers agencies to navigate the complexities of sustainability while adapting to the ever-evolving events landscape. If you’re recognised in this year’s Power 30, congratulations – well done!”

Susie Harwood, micebook editor, added: “This list recognises agencies that are not only taking responsibility for their own business practices but are also actively enabling more sustainable outcomes for the events they deliver. It provides a valuable reference point for corporates looking to work with agencies that take sustainability seriously, in practice rather than just in principle.”
