Extended Data Fig. 6: The abatement costs and interest costs of the 1.5 °C (RCP 1.9) scenarios as function of the percentage of carbon debt reduction compared with the baseline scenario.
a, b, The abatement costs (a) and interest costs (b) of the 1.5 °C (RCP 1.9) scenarios is compared with the baseline scenario (in which rd = 0) for all 468 RCP 1.9 scenarios, grouped by the carbon debt interest rate (rd) and the cost and capacity parameters of DACS. DACS cost parameters range from low to high (that is, LoCost, MedCost and HiCost); capacity limits include 10% and 30% of baseline emissions (that is, LoCap and HiCap). a, Total discounted abatement costs excluding interest costs (that is, ABM + RES + NNE as in Fig. 4 and Extended Data Figs. 3–5). b, Total discounted interest costs (that is, INT as in Fig. 4 and Extended Data Figs. 3–5).
