The Institute for Carbon Responsible Removalis an initiative of American University’s School of International Service. It was founded in 2018 in response to growing scientific and political attention to carbon removal technologies and practices. The Institute grew out of the Forum for Climate Engineering Assessment, a separate research initiative dedicated to assessing the social, ethical, political, and legal implications of emerging technologies that fall under the broad rubric of climate engineering.

The Institute’s work is made possible through the generous support of the The New York Community Trust, the Sloan Foundation, Preston Werner Ventures and the Chan Zuckerberg Initiative.


Simon Nicholson Co-director

Simon Nicholson, PhD, is an associateprofessor for the Global Environmental Politics program at the School of International Service at American University. His work focuses on global environmental governance, global food politics, and the politics of emerging technologies. His work on carbon removal is informed by a deep sense of concern about the lack of effective response to climate change coming from mainstream political and social processes. At the same time, prior work on the politics of technology tells him that promising technological responses to complex social problems can too easily go awry, can fail to fulfill expectations, can be repurposed for ill-conceived or nefarious ends, or can entrench the very dynamics that drive the problems to which the technologies are attempting to respond. He brings cautious optimism to the carbon removal conversation, with emphasis on “cautious.” Among his publications, Nicholson is co-editor (with Sikina Jinnah) of (MIT Press, 2016), and (with Paul Wapner) of (Routledge, 2015).
