Summary/Abstract
This roadmap explores the potential for direct air capture of carbon dioxide to contribute to climate mitigation (and provide feedstock for commercial processes). Chapter 1 of the roadmap examines the need for carbon dioxide removal broadly and surveys the range of CDR approaches available. Chapter 2 describes direct air capture technologies. Chapter 3 discusses the advantages of direct air capture. Chapter 4 explores challenges facing direct air capture, and Chapter 5 considers research pathways for addressing them. Chapter 6 discusses policy options. Chapter 7 offers findings and recommendations.
