Professor Ottmar Edenhofer examines why large-scale carbon dioxide removal (CDR) is essential for meeting climate targets and establishing a third pillar of climate policy alongside abatement and adaptation.
Even with rapid innovation, projected levels of carbon dioxide removal (CDR) remain far below what is required to stay within internationally agreed temperature limits. The main barriers to technology development and deployment are institutional, economic, and political – reflected in governance gaps that undermine incentives to invest in and deploy CDR at scale. He presents market and governance solutions, including innovative “clean-up certificates” and a European Carbon Central Bank to manage net-negative emissions within carbon market frameworks. By “cleaning up” the atmosphere, CDR can also help reduce free-riding incentives in international climate co-operation.
Professor Edenhofer identifies planetary carbon management as the central challenge of 21st-century climate policy, a necessary third pillar of climate policy, alongside emissions reduction and adaptation, and as a critical enabler of net-zero and net-negative pathways.
