The 2022 NASEM report ranked six mCDR pathways; this update narrowing in on OAE (ocean alkalinity enhancement) tracks where the field has actually moved. The governance gap is the binding constraint now, not the chemistry.

A formal comment from Lunstrum, Keller, Hartmann and colleagues on an OAE manuscript shows the measurement bar is rising fast. Apply that standard to river alkalinity enhancement and the hard question is retention: what fraction of added alkalinity reaches the sea as durable bicarbonate.

River alkalinity enhancement has no registry methodology. Not at Isometric, Puro, or Frontier. The Kvina proof-of-concept lands into a protocol vacuum, and OAE templates will not lift-and-shift into freshwater chemistry.
