Is CO₂ removal (negative emissions) needed in 1.5°C scenarios?

Highly likely. There are two 1.5°C scenarios with no or limited overshoot in #SR15 that do not have CO₂ removal (from the POLES) model, all others use afforestation, BECCS, DAC, etc
And here are the CO₂ emissions for the 1.5°C scenarios with no or limited overshoot. The black lines are the 4 Illustrative Scenarios used in the SPM. The red are the two POLES scenarios without CO₂ removal.
A reasonable question is how much of the CO₂ removal is afforestation?

Initially, almost all CO₂ removal is afforestation, but that share gets smaller over time as BECCS (in particular) grows. A few scenarios only use afforestation (from LED & C-ROADS).
