As the remaining carbon budget for limiting warming to 1.5 °C rapidly diminishes, it is clear that, besides decarbonization, the world will need to remove 100–1000 GtCO2 from the atmosphere by the end of the century. Yet, Africa, where many carbon removal schemes are planned, remains a ‚blindspot‘ in existing studies. There is limited understanding of the trade-offs and synergies associated with carbon removal within Africa’s energy-land-water system. To address this research gap, a stylized net-zero emissions in Africa by 2050 was modeled, with focus on three land-based biological carbon removal approaches: afforestation/reforestation, bioenergy with carbon capture and storage, and biochar.
