Extended Data Table 2 The effect of feasibility constraints at formative, acceleration, and stable growth phases used in this study on long-term cumulative capture and storage of CO2 in Gt by 2070 and 2100 for meeting climate targets

From: Feasible deployment of carbon capture and storage and the requirements of climate targets

  1. The table shows different groups of pathways before (’all pathways’) and after imposing feasibility constraints (that is by 2030, 2040, and over the long-term) for 1.5°C- and 2°C-compatible IPCC AR6 pathways (top) as well as for IPCC Scenario Categories (bottom of each panel). Categories vary by the global mean surface air temperature change by 2100: C1 pathways stay below 1.5°C with no or limited overshoot with a 50% probability; C2 - below 1.5°C with high overshoot; C3 - likely below 2°C; C4 - below 2°C10. C1 and C2 are thus grouped as 1.5°C-compatible; C3 and C4 as 2°C-compatible. Numbers in brackets in the first column show the number of pathways in each group. Numbers in the following columns show median values of CO2 captured and stored by 2070 (upper panel) and 2100 (lower panel); numbers in square brackets show the interquartile range of these values. Full ranges are reported for pathway groups with N < 10
