Named in micebook’s Power 30 Most Sustainable Agencies 2025-26

Brighter is proud to have been named one of micebook’s Power 30 Most Sustainable Agencies 2025-26.

The line-up celebrates the UK event agencies leading the way in ESG excellence and sustainable event delivery.

Brighter Event Executive Ellie Cunningham was on hand to pick up our award at micebook’s EXPO in London, where micebook and event:decision revealed the 2025-26 Power 30 line-up during a launch ceremony.

The Power 30 list evaluates agencies based on both internal sustainability commitments and their ability to deliver low‑impact, high‑value events for clients.

Brighter had to complete a rigorous questionnaire covering strategy, accreditation and real event case studies, with submissions scored and bench marked to provide the clearest view of sustainability performance across the sector.

This year, the list includes eight new entrants and 22 returning agencies, demonstrating industry‑wide momentum.

To see Brighter named among some of the most respected and forward‑thinking agencies in the UK is a testament to the work our team has been doing for years to embed sustainability into every stage of the event lifecycle.

Sustainability has long been a core pillar of how Brighter plans and delivers events.

Over the past year, we have taken significant steps to expand and formalise that commitment, achieving the ISO 20121 certification for Sustainable Meetings and Events following a comprehensive audit.

Our sustainability journey also runs deep into the experiences we create with our ethos centring on sourcing sustainable venues, leveraging smart tech and designing immersive, meaningful moments that inspire people while reducing impact.

Susie Harwood, editor of micebook, said:

“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.”

Being named one of micebook’s Power 30 Most Sustainable Agencies reinforces our mission to create unique connections and unforgettable experiences, with no compromise to the planet.

While we’re honoured to be recognised as one of micebook’s Power 30 for a second time, we also know there is much more to do.

We’ll continue investing in our people, our processes and our partnerships to ensure sustainability remains at the heart of everything we do.

Thank you to micebook and event:decision for this acknowledgement and congratulations to all the agencies featured this year.
