Fig. 3: Global net carbon dioxide removal from expanding biomass plantations for BECCS under consideration of planetary boundary constraints.

From: Multiple planetary boundaries preclude biomass crops for carbon capture and storage outside of agricultural areas

a Impacts of incremental consideration of planetary boundary (PB) constraints on global BECCS potential. Net carbon dioxide removal (CDR) is displayed for three carbon removal efficiency (CEff) pathways (optimal, moderate, low, assuming a biomass-to-electricity conversion). The error bars reflect the range based on mid-century RCP4.5 climate change scenarios from five general circulation models (2036–2065). Percentage changes refer to the relative incremental effect of each constraint. b Projected CDR demand in scenarios likely limiting warming to <2 °C (C1–C3) included in IPCC’s 6th assessment report (AR6)1, boxplots show median and interquartile ranges for 2050 and 2100 respectively (see Supplementary Methods). c Single mean effect of the PB constraints relative to the unconstrained CDRonly scenario.
