Captain's CDR Log #197: Why 22 days at Puro just rewrote the working-capital math for durable suppliers
Captain Drawdown’s daily logbook on every CDR story, paper, and expert voice — so you don’t have to read them all. Puro.earth says its median time from carbon removal supplier submission to credit issuance dropped to 22 days in 2026, down from 40 days in 2025, per its own LinkedIn announcement. That figure is self-reported and not independently audited, so treat it as a claim, not a verified statistic. But if it holds, my forecast is this: by Q1 2027, time-to-cash, not price per tonne, becomes the primary axis of competition among durable CDR registries, and registries that cannot clear issuance in under 30 days will lose material share of new biochar and BECCS (bioenergy with carbon capture and storage) supplier registrations. The reason is arithmetic. Every day a verified tonne sits unissued is a day of working capital a thin-margin operator must finance. Cutting median latency from 40 to 22 days shortens the cash conversion cycle by nearly three weeks per batch. On a simple 12 percent annual cost of capital, that is roughly 0.6 percent of credit value saved per cycle, illustrative math on my part, and it compounds across every batch a facility ships. ...
