  • Summary

    On the CDR side of our toolbox, the go-forward imperative is to stomp the accelerator. We have costly and early-stage but viable technologies by which to remove carbon both from flues and from direct air, with industrial interventions holding more promise than biological ones. The challenge is to mature and scale these technologies as rapidly as possible. A 2019 report from the National Academy of Sciences, Engineering and Medicine laid out a thoughtful agenda for the path forward and suggested an expenditure of $9 billion over the subsequent 10 years to mature the technologies for DACCS, BECCS, several biological removal processes, and geologic storage. The Trump administration did not act on this recommendation, but the imperative remains.
