ALT Six-panel line graph showing CDR deployment in GtC/yr, the social cost of carbon in USD/tCO2, gross and net emissions in GtC/yr, atmospheric carbon concen-tration in GtC, and temperature increase in °C from 2020 to 2200. DACCS and OAE deployment increase strongly after mid-century, reaching about 8–10 GtC/yr each by 2200, while OIF remains below about 0.5 GtC/yr throughout. Relative to the scenario without CDR, combined CDR leads to net-negative emissions, lower atmospheric carbon concentrations, and lower temperature increases by 2200. Differences in gross emissions and the social cost of carbon remain comparatively small.

ALT A waterfall plot. It consists in a big black bar on the left side (initial emissions), with smaller bars stacked side by side showing changes in emissions in each country compared to the baseline. The small bars cumulate to another bar on the right, which shows the emissions in the counterfactual emissions. A horizontal line shows how much emissions are reduced in the coalition countries (EU, Canada, Japan, Korea, Taiwan) compared to the baseline (953 MtCO2) and another line shows how much emissions are reduced in total (691 MtCO2). The difference between these two numbers correspond to the contribution of non-coalition countries to the change in emissions (691).
