At the end of August, Bristol hosted one of the UK’s first large-scale music festivals powered entirely by clean energy, a milestone driven by pioneering efforts from Massive Attack. The Bristol-based band, fronted by Robert del Naja and Grant Marshall, known as 3D and Daddy G, has been grappling with the environmental impact of traditional touring for several years. Their efforts culminated in the Massive Attack x Act 1.5 Festival, held on Bristol Downs, a 412-acre protected common land in the city, which drew some 55,000 attendees over several days.
The concept for a fully green festival was born out of frustration in 2018 when Del Naja and Marshall realized that conventional tours generated carbon emissions far beyond targets outlined in the Paris Agreement. Tours can produce anywhere between 5,000 to 20,000 tonnes of CO2, equivalent to thousands of petrol vehicles running for a year. To tackle this, the band enlisted documentary filmmaker and climate activist Mark Donne to help coordinate a solution. Researchers from the Tyndall Centre for Climate Change Research developed a comprehensive plan, addressing all aspects of festival production with clean technology.
The festival successfully deployed an innovative power system using GeoPura hydrogen batteries instead of diesel generators. The batteries produce electricity quietly and emit only water vapor, eliminating noise and air pollution backstage. The festival’s organizers even offered the clean water produced to performers. This approach demonstrated that large-scale live shows could maintain high production values—including lighting and sound—without the environmental drawbacks usually associated with diesel-powered equipment.
Transportation logistics were also overhauled. The organizers reopened several train stations that had previously closed to facilitate electric train travel for attendees, reducing reliance on fossil-fuel vehicles. Haulage for equipment and supplies was shifted entirely to electric vehicles, marking an unprecedented comprehensive effort to minimize carbon footprints across all festival operations.
Despite the success, Del Naja expressed concern that much of the music industry remains resistant to change. He noted that, in contrast to their minimal convoy, other major artists on tour use dozens of trucks—often publicizing their fleets on social media—which he described as a status symbol that sidelines environmental responsibility.
Following the festival, momentum initially faltered. Helen Godwin, who became the metro mayor for the West of England in May 2025, emphasized the importance of extending the festival’s green approach across the region’s many events. With funding available from a clean energy fund attached to her office, Godwin has supported efforts to make sustainable power solutions more widely accessible for the area’s cultural and entertainment festivals.
Del Naja acknowledged the urgency of the situation, referencing their forced cancellation of a Primavera Sound Festival headline in Barcelona due to extreme weather conditions worsened by climate change. “Trying to contingency plan around so many elements of severe weather is becoming harder and harder,” he said. The festival’s clean energy trial in Bristol highlights a potential path forward for the live music industry amid growing environmental challenges.
