Figure 2: Illustration of the default mitigation floors and corresponding gross negative emissions.
From: Negative emissions physically needed to keep global warming below 2 °C
(a) Only one compatible emissions trajectory (Ecomp) and all the possible mitigation floors (Efloor) for this trajectory. (b) In a given year, the requirement for negative emissions (Eneg) corresponds to the gap between the mitigation floor and compatible emissions, should there be any.
