Cui et al. (2026): Using Carbon Dioxide Removal for a Habitable Post-2050 Net-Zero Emission World: Contributions and Limitations

United Nations (UN) encourages sovereign states to take prompt and concrete measures to accomplish net-zero emissions by year 2050, requesting carbon dioxide removal (CDR) technologies to be prepared and implemented in such ambitious climate action roadmap. However, whether CDR technologies should be further promoted or discontinued post net-zero emission year remains unclear. In this Earth-system modelling research, the authors compare UN-suggested 2050 net-zero emission scenario against other common climate mitigation scenarios outlined by shared social-economic pathways (SSPs). They also simulate continued CDR implementations after net-zero emissions, which is hypothetically achieved in year 2050 and 2070 respectively, to investigate how CDR can impact the global climate throughout the whole 21st and 22nd centuries.
