Speaker Bio
Named to the TIME100 Climate List of the world’s most influential climate leaders, Adam Gardner is a musician and environmental innovator who has spent more than two decades driving climate action through the power of live music. As frontman of the band Guster and co-founder of the nonprofit REVERB, Adam has transformed the way artists, fans, and the music industry confront the climate crisis.
Since 2004, REVERB has partnered with leading artists—including Billie Eilish, Dave Matthews Band, Harry Styles, Dead & Company, LORDE, Fleetwood Mac, Jack Johnson, Shawn Mendes, Tame Impala, and many more—to deliver measurable impact:
Eliminated 400,000+ tonnes of CO₂e
Prevented the use of 4 million+ single-use plastic bottles at concerts
Mobilized 8+ million fan climate actions
Supported 6,000+ nonprofits worldwide
Funded 150+ carbon-fighting and climate justice projects
Raised $22 million+ for environmental causes
Music Decarbonization Project
Through REVERB, Adam co-created the Music Decarbonization Project, an initiative fast-tracking innovative climate solutions to directly eliminate carbon solutions at their source. This effort has powered major stages at Lollapalooza, Austin City Limits, Portola, and Healing Appalachia with hybrid battery and solar systems, cutting diesel use by over 90%, avoiding thousands of gallons of fuel, and demonstrating a scalable path toward a fossil-free future for festivals. The project also released a first-of-it-kind Concert Travel Study in 2025, engaging 35,000 fans and charting strategies to reduce music’s largest carbon footprint—audience travel.
Adam has twice testified before Congress in support of environmental legislation, led delegations of musicians into the rainforests of Guatemala and Peru to witness the effects of illegal logging, and in 2019, REVERB was named the Official Music and Public Engagement Partner of the United Nations Environment Programme. A frequent voice in outlets such as Variety, TIME, and Pollstar, Adam continues to make the case that sustainable touring is both a cultural imperative and an economic opportunity.
