+1Short answer from the current literature: probably not at the scale required, under current cost trajectories, without policy support that does not yet exist in any major economy. But "probably not" is not the same as "no," and the detailed picture matters. Direct air capture, enhanced weathering, and BECCS each have different cost curves, energy requirements, land-use implications, and deployment timelines. This review would assess whether any credible combination of technologies could reach gigaton-scale removal by 2055 under a range of policy scenarios - not to offer false hope, but to identify where research investment would have the highest expected return.
