This article examines the technocentric bias that characterizes climate mitigation literature, focusing on the reports of the IPCC’s Working Group III.

With the emergence of new carbon dioxide removal technologies and the generation of new empirical data on relevant sources and sinks, it may be valuable to consider new methods in the IPCC Guidelines. If adopted, these new methods will broaden the base of sinks and sources that inventory compilers should routinely monitor and facilitate their estimation and reporting in future national inventories. With this context in mind, the IPCC tasked the Task Force on National Greenhouse Gas Inventories (TFI), in January 2024, to develop a Methodology Report on Carbon Dioxide Removal Technologies, Carbon Capture Utilisation and Storage activities (Decision IPCC-LX- 9). An Expert Meeting on this topic was also mandated by the IPCC and held in Vienna on 1-3 July 2024. This was the first step along the journey to prepare the Methodology Report and this document is a Report of that Meeting.

National greenhouse gas inventories (NGHGIs) and scientific assessments of anthropogenic emissions follow different accounting conventions for land-based carbon fluxes resulting in a large difference in the present emission estimates, a gap that will evolve over time. Using state-of-the-art methodologies and a land carbon-cycle emulator, the authors align the Intergovernmental Panel on Climate Change (IPCC)-assessed mitigation pathways with the NGHGIs to make a comparison.

“Öl- und Gasproduzenten wollen mit CO2-Speichern ihr Geschäft grün waschen. Doch auch der Weltklimarat rechnet mit technischen CO2-Speichern. Warum wir sie brauchen, erklärt IPCC-Autor Oliver Geden.”

“Das UN-Klimasekretariat legt eine erste weltweite Bilanz vor: Die Architektin des Paris Klimaabkommens spricht von einem „Moment der Wahrheit“. […] Der Entwurf der Bestandsaufnahme fasst nun zahlreiche Beiträge von Regierungsfachleuten, Wissenschaftler:innen und der Zivilgesellschaft zusammen. Er muss von den Staaten noch akzeptiert werden. Das Dokument findet durchaus deutliche Worte. Um die Klimaziele zu erreichen, sei „eine radikale Dekarbonisierung aller Wirtschaftssektoren erforderlich“, steht in dem Entwurf. Weiter heißt es, zentrale Elemente einer gerechten Energiewende seien der Ausbau von erneuerbaren Energien sowie das Aus für fossile Brennstoffe ohne CO₂-Abscheidung und -Speicherung (CCS). Allerdings stellt der Bericht auch klar, dass die umstrittene CCS-Technologie nur in Ausnahmefällen zum Einsatz kommen soll.”

The IPCC reports, and in particular the respective Summary for Policy Makers (SPM), provide a scientific basis for negotiations under the United Nations Framework Convention on Climate Change (UNFCCC). They are a key reference in the global climate debate. The most recent Synthesis Report (SYR) is considered one of the most important sources of information for the first Global Stocktake under the Paris Agreement, which is to be concluded at the UNFCCC Conference of the Parties (COP28) in Dubai in December 2023. The knowledge politics surfacing in controversies that were visible during the report’s adoption reflect the conflicting interests that will shape the upcoming round of new emission reduction and financing pledges.

The authors analyze the range in CDR volumes in AR6 WGIII pathways by exploring relationships between variables as potential driving forces, focusing on CDR in 2050 and scenario properties linked to reaching net-zero CO2. It is also shown how the relative and absolute contribution of CDR to total mitigation up until reaching net-zero CO2 substantially differs across scenarios.

Carbon Brief’s team of journalists has delved through each page of the IPCC’s AR6 full synthesis report to produce a digestible summary of the key findings and graphics. “The synthesis report is the last in the IPCC’s sixth assessment cycle, which has involved 700 scientists in 91 countries. Overall, the full cycle of reports has taken eight years to complete. The report sets out in the clearest and most evidenced detail yet how humans are responsible for the 1.1C of temperature rise seen since the start of the industrial era. It also shows how the impacts of this level of warming are already deadly and disproportionately heaped upon the world’s most vulnerable people. The report notes that policies in place by the end of 2021 – the cut-off date for evidence cited in the assessment – would likely see temperatures exceed 1.5C this century and reach around 3.2C by 2100.”

“Summary report by world’s leading climate scientists sets out actions to stave off climate breakdown.[…] What should governments do? Reduce emissions sharply and give up fossil fuels, through investments in renewable energy and other low-carbon technologies, increase energy efficiency, rethink agriculture and restore forests and degraded natural landscapes. It may also be necessary to develop technologies that suck carbon dioxide from the air, called “direct air capture”, or explore other means of “climate repair”.”

The high-level webinar features IPCC authors, government representatives and leading carbon removal experts to discuss how carbon removal is a critical tool in our toolbox to address the climate crisis. Speakers will examine what the latest IPCC report says about carbon removal, which approaches are progressing the fastest, who are the frontrunners in the carbon removal market, how to address equity concerns, and what investments governments and businesses need to make now to rapidly scale up CDR deployment over the next 10 years.
