Figure 6.29 | Reductions in CO2 emissions relative to 2020 levels for scenarios that limit/return warming to 1.5°C (>50%) with no or limited/after a high, overshoot, and scenarios that limit warming to 2°C (>67%), with action starting in 2020 or NDCs until 2030, during 2030–2050. Boxes indicate 25th and 75th percentiles while whiskers indicate 5th and 95th percentiles. Source: AR6 Scenarios Database.
