Gidden et al. (2023): Fairness and feasibility in deep mitigation pathways with novel carbon dioxide removal considering institutional capacity to mitigate

Matthew J Gidden, Elina Brutschin, Gaurav Ganti, Gamze Unlu, Behnam Zakeri, Oliver Fricko, Benjamin Mitterrutzner, Francesco Lovat, Keywan Riahi IN: Environ. Res. Lett. 18, 074006, DOI 10.1088/1748-9326/acd8d5

The authors analyzed scenarios that include direct air capture of CO₂ with storage (DACCS), a novel CDR technology that is not dependent on land potential and can be deployed widely, as well as regional variations in institutional capacity for mitigation based on country-level governance indicators. They find that including novel CDR and representations of institutional capacity can enhance both the feasibility and fairness of 2 °C and 1.5 °C high-overshoot scenarios, especially in the near term, with institutional capacity playing a stronger role than the presence of additional carbon removal methods.
