The State of Carbon Dioxide Removal

The third edition of the independent and global scientific assessment of the State of Carbon Dioxide Removal report continues to analyse core developments in CO2 removal in May 2026.

The first edition (January 2023) established, among other things, the concept of the »CDR gap« - a quantitative estimate of the gap between the current or announced level of CO2 removal and the level that would be necessary to achieve the long-term temperature goal of the Paris Agreement. Building on this, the second edition of The State of Carbon Dioxide Removal improved and expanded the original approach, providing more comprehensive data collection and analysis, in the form of a status report and a new data portal.

In the third project phase, the status report expanded further, now including a chapter on the costs and potential of individual methods and a novel database for CDR-relevant policies in the G20. The data portal was considerably expanded and visually prepared for a wider audience. The project team is also developing concepts for the international institutionalisation of CO2 removal governance. Shorter Insight Reports, the first on CO2 removal in the national climate plans (NDCs) submitted under the Paris Agreement, will also be produced. In addition to these core products, The State of Carbon Dioxide Removal project also regularly produces peer-reviewed publications in which the analyses from the report are deepened and expanded.

The project is coordinated by the Smith School of Enterprise and the Environment at the University of Oxford, with the SWP as one of five organizations in the consortium. Over 70 authors have contributed to the third edition. SWP is represented on the consortium's executive team by Oliver Geden. Leona Tenkhoff works as a research associate primarily on the CO2 removal policy and governance chapter.

Project duration: since 2022

The third phase of the State of Carbon Dioxide Removal is funded by the UK Natural Environment Research Council, the European Research Council and the Quadrature Climate Foundation.
