Winners announced!

Yesterday saw the live session at micebook EXPO where we announced the Power 30 Most Sustainable UK Agencies 2026!

See the winners & headlines here.

The Power 30 Most Sustainable Agencies, now in it’s second year, are evaluated based on your sustainable internal business practices and the ability to deliver responsible & sustainable outcomes for client events. Unlike many industry recognition programs, this initiative is scored according to pre-published credentials rather than being subjectively judged. The results are qualified, scored, and benchmarked to produce a list of the best performers in sustainability, showcasing real capabilities and proof points for responsible agencies.

View this year’s entry criteria for Power 30

As responsible & sustainable event delivery becomes a growing priority for clients, agencies that leverage industry data are able to progress and position themselves as leaders in environmental and social responsibility. Recognition in the Power 30 enables agencies to showcase their commitment to sustainable practices and attract clients who value stewardship and ethical delivery. More broadly, the campaign helps raise the standard across the industry. It encourages continuous improvement, collaboration, and knowledge-sharing, equipping agencies to navigate the complexities of sustainability while adapting to the evolving demands of the events sector.

Let’s continue our journey together

Congratulations to the recognised agencies this year and those recognised in the 2024-25 Power 30. For those striving to be included in next year’s edition, the campaign serves as both a benchmark and a motivation to continue advancing sustainable practices. The journey toward a more sustainable events industry is ongoing—and every step forward counts.
