CONGRATULATIONS TO ALL THOSE RECOGNISED IN 2026!

event:decision and micebook are proud to announce the launch of the  Power 30 Most Sustainable Agencies 2025-26.

This prestigious list celebrates the top 30 most sustainable event agencies based in the UK market, once again spotlighting those leading the way in delivering sustainable, responsible events.

This follows the results and success of the 2024-25 and 2025-6  Power 30 Most Sustainable Agencies UK.

New for 2026-7 is the Production Power Ten, recognising the invaluable partnerships that Technical Production and AV companies add to the event sector.

Who can enter?

Entries are open to all organisations with a UK operating office:

Power 30 Most Sustainable Agencies:

  • Full-service agencies
  • Logistics agencies
  • Exhibition design & build agencies

Production Power Ten:

  • Technical and Creative Production agencies
  • Creative AV specialists
  • AV & equipment hire

To those returning from the 2024, 2025 and 2026 cycle, welcome back! We’re thrilled to see your continued commitment. And to first-time entrants: thank you for joining this growing community – we’re here to support you every step of the way.

The submission process

Agencies and Production partners will each be assessed based on two key areas:

Part 1 – event delivery outcomes

Provide details for three separate events, or your supply within. Additional value is given for each from a different calendar year and for different clients. Events should contain a substantial in-person element, rather than be purely virtual. If you have entered in previous years, please provide new event examples, if available.

For each, we ask for details of sustainability practices across:

  • Environmental impact
  • Social responsibility
  • Governance process

Submission of event details is designed to be quick & easy and single-click format.

event:decision retain the right to request evidence relating to individual answers in this section, if required. Qualification and recognition is dependent upon delivering such evidence on request.

Part 2 – internal business practices.

This element of the submission refers directly to your own company.

The section asks for formally recognised accreditations, going back up to three years. If you have attained one level and are progressing to the next, please add these details in the comments. We further request details of the formal measurement of your own carbon footprint (excluding any event-related emissions), as well as detailing any socially beneficial activities that you undertake as a company.

It is possible to score well under the assigned criteria even if you have few formal accreditations but evidence of sustainable event delivery, and vice versa. Any information shared in relation to client events or internal operations will remain confidential, unless permission is requested from & granted by you.

You can pause and return to your form at any point using the Save & Continue feature. A unique link will be sent to your email, allowing you up to 90 days to complete your submission and time for you to collaborate with relevant departments.

  • Entry fee: £249 + VAT
  • Deadline: Friday 23rd October 2026

What happens next?

Once submissions close, entries will be scored – not judged —-against a consistent, criteria-based framework. This ensures a fair, evidence-based process that produces a benchmarked list of sustainability leaders in the UK event industry.

Part 1 data, relating to event outcomes is equally weighted between conference, activation and stand-delivery event types.

Part 2 data, relating to your company operations is consistant across Most Sustainable Agencies and Production Power Ten.

Save the date: 1-2 February 2027. Recognised P30 agencies and Production Power Ten winners will be celebrated at micebook EXPO, London. You will be notified by the end of November 2026, if you feature in the Power 30 or Power Ten Production.

If you have any questions, please contact power30msa@eventdecision.com

We look forward to receiving your submission!

Let’s Go!
