Estimates of how much we will be able to scale-up carbon removal tech vary widely.
Direct air capture and bioenergy with carbon capture and storage could produce permanent removals that are not at risk from wildfires like trees are - but we should not rely on them entirely. Conservative estimates of their potential suggest the two technologies combined could only produce a fifth of the removals we will need.
