Why Talk about Carbon Removal?

Abstract

Talk of removing carbon dioxide from the atmosphere is spilling out of scientific circles and into the realm of climate politics and policy. Civil society has a vital role to play in ensuring that this conversation is responsive to social needs and develops in constructive and appropriate ways. This report provides a starting point to help environmental and social justice non-governmental organizations (NGOs) engage in the growing conversation about carbon removal.

Section 1 of the report argues that the world needs to grapple seriously with large-scale carbon removal and long-term storage, exploring both the rationale for considering carbon removal and the associated risks and downsides. Section 2 provides a brief introduction to the range of options for large-scale carbon removal. Section 3 surveys the existing conversation in different domains, from academia to philanthropy to civil society. Section 4 considers the relationship between carbon removal and mitigation. Section 5 sketches a research agenda for assessing various approaches to carbon removal.
