Holly Jean Buck is an associate professor of environment and sustainability at the University at Buffalo, as well as a geographer and environmental social scientist. Her research focuses on how communities can engage with emerging climate and energy technologies to help build a regenerative society. Currently, she is investigating the social and political pathways for returning carbon to the ground, and what it would take to deploy carbon removal in equitable and just ways.

She is the author of After Geoengineering (Verso, 2019), which explores best-case scenarios for climate intervention, and Ending Fossil Fuels: Why Net Zero Is Not Enough (Verso, 2021), which sets out how societies might carry out a deliberate and managed phase-out of fossil fuels. Through both teaching and research, Buck challenges conventional climate narratives while opening up new possibilities for collective action.
