Cheerful Twentyfirst has been named one of the Power 30 Most Sustainable Agencies 2025–26, an industry accolade curated by event:decision and micebook that celebrates UK agencies leading the way in embedding sustainability across both internal operations and client delivery.
The Power 30 list recognises agencies that demonstrate meaningful, measurable action across environmental, social and governance priorities. For Cheerful Twentyfirst, the award reflects the agency’s long-term commitment to sustainability as outlined in its latest CSR Charter 2025–2027, built around two core pillars: Accountable Carbon and Access to Industry.
Sustainability has been embedded into Cheerful Twentyfirst’s operations since 2019, when the agency began formally measuring its carbon footprint. Since then, the business has offset its operational emissions annually through Gold Standard carbon credits, supporting clean water programmes in Buenos Aires, Vietnam and across Asia. This data-led approach has informed the agency’s Net Zero roadmap and science-based reduction targets.
As part of its current CSR commitments, Cheerful Twentyfirst has pledged to reduce Scope 3 emissions by a further 24% by 2030, representing an overall 30% reduction in total emissions since 2019, and is joining the Science Based Targets initiative (SBTi) in 2026 to strengthen accountability and transparency.
Beyond its own footprint, Cheerful Twentyfirst supports clients in reducing the environmental impact of their events through carbon and ESG reporting and sustainable production practices. To date, the agency has supported over 100 event marketers in making informed, data-driven decisions to reduce emissions across live experiences.
Andrew Harvey, Managing Director at Cheerful Twentyfirst, shared:
“We were so proud to be recognised in the inaugural Power 30 Most Sustainable Agencies in 2025. Now our second year on this list, 2026 is just as meaningful because it reflects the work happening behind the scenes every day across our teams. Power 30 is a wonderful motivation to continue that important work.”
