Fig. 5: Regional outcomes and equity implications.

Regional outcomes under a 2 °C end-of-century temperature target, including: a cumulative CO₂ emissions for fossil fuels and industry from 2020 to 2100 in the Plan High & Learn High scenario, b cumulative CO₂ removal from DACCS and BECCS (in both electricity and liquids) from 2020 to 2100 in the Plan High & Learn High scenario, c ratio of the difference in cumulative CO₂ emissions in the Plan High & Learn High scenario and the Plan High & Learn Low (Keep Target) scenario over cumulative CO₂ emissions in the Plan High & Learn High scenario (i.e., the percent reduction in CO₂ emissions necessary to meet Paris goals if actors are wrong about high CDR), d ratio of the difference in cumulative CO₂ emissions in the Plan Low & Learn High (Keep Target) scenario and Plan Low & Learn Low scenario over cumulative CO₂ emissions in the Plan Low & Learn Low scenario (i.e., the allowed percent increase in CO₂ emissions if actors are wrong about low CDR).
