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.

We look forward to receiving your submission!
