Figure 6.27 | Net regional (R6) CO2 emissions from energy across 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 with NDCs until 2030, during 2020–2050 (Source: AR6 Scenarios Database). Boxes indicate 25th and 75th percentiles, while whiskers indicate 5th and 95th percentiles. Most mitigation scenarios are based on a cost-minimising framework that does not consider historical responsibility or other equity approaches.
