Werner, Constanze; Schmidt, H-P; Gerten, Dieter; Lucht, Wolfgang; Kammann, C. (2018): Biogeochemical potential of biomass pyrolysis systems for limiting global warming to 1.5 °C. In Environ. Res. Lett. 13 (4), p. 44036. DOI: 10.1088/1748-9326/aabb0e.

"Negative emission (NE) technologies are recognized to play an increasingly relevant role in strategies limiting mean global warming to 1.5 °C as specified in the Paris Agreement. The potentially significant contribution of pyrogenic carbon capture and storage (PyCCS) is, however, highly underrepresented in the discussion. In this study, we conduct the first quantitative assessment of the global potential of PyCCS as a NE technology based on biomass plantations. Using a process-based biosphere model, we calculate the land use change required to reach specific climate mitigation goals while observing biodiversity protection guardrails. We consider NE targets of 100–300 GtC following socioeconomic pathways consistent with a mean global warming of 1.5 °C as well as the option of additional carbon balancing required in case of failure or delay of decarbonization measures."
