Captain Drawdown’s daily logbook on every CDR story, paper, and expert voice — so you don’t have to read them all.

Five numbers this week trace the same shape: CDR operators are retreating from headline tonnage promises and digging into narrow positions they can actually defend. The capital is going to certification rails, embedded products, and the power layer underneath removal. The gigatonne talk is getting quieter, and the invoices are getting more specific.

$40 million. Isometric’s Series A, led by AVP with Lowercarbon and Plural, per the CDR.fyi June 2026 recap. The notable part is where it goes: expanding the Certify platform beyond CDR into the broader environmental credit stack. Measurement, reporting, and verification (MRV) infrastructure is now attracting more operator-adjacent capital than tonnes are. Owning the rails that every credit rides on is a stronger position than selling any single credit, something visible in deals like Mombak’s first Isometric-verified enhanced weathering credits.

$134 million. Quaise Energy’s Series B for superhot geothermal in Oregon, reported by Canary Media. That is larger than most 2026 DAC raises. Clean firm power is the input cost that decides whether DAC pencils out, and investors are funding the input rather than the capture plant. If you run a DAC project, your power purchase agreement is your business model, and the money knows it.

10 years. Verde Resources signed a decade-long offtake for biochar in asphalt with Ergon, the largest US asphalt supplier, per Carbon Herald. The tonne here is a byproduct of a paving invoice. That inverts the usual model where credit revenue carries the project. A ten-year industrial contract is bankable in a way that spot credit sales are not, and other operators are noticing.

4.7x. Puro Registry reports a 4.7x increase in end-buyer beneficiaries of its removal certificates between 2020 and 2025 (Puro.earth on LinkedIn). Diversification is real. But more buyers splitting a still-small market means volume per buyer is shrinking. For an operator, that changes everything about delivery: more counterparties, smaller lots, higher transaction costs per tonne. It pushes projects toward platform intermediaries who aggregate demand, like the CUR8 and Isometric 2030 portfolio offering.

Negative $26 per tonne. Chris Bataille (@chrisbataille.bsky.social on Bluesky) puts the implicit global fossil subsidy in price terms: “we have a negative CO2 price of -$26/t CO2e,” dividing roughly a trillion dollars in support across 38.4 gigatonnes of annual emissions. Every operator revenue line in this brief, Verde’s asphalt margin, Isometric’s verification fee, Puro’s certificate flow, is being built against that headwind. Removal only makes sense as a complement to cutting emissions, never as a substitute, and this number shows how far the underlying incentives still tilt the wrong way.

The pattern. Put the five together and the operator playbook for 2026 is legible. Money flows to whoever owns certification infrastructure, controls clean firm power, or embeds removal inside an existing industrial contract. Pure-tonne pitches without one of those moats are getting harder to close, while buyer fragmentation raises the cost of selling each tonne. Ken Caldeira (@kencaldeira.com on Bluesky) noted a parallel suspicion in adaptation talk: “if you talk about adaptation, people suspect you are not serious about reducing greenhouse gas emissions.” The same suspicion now attaches to operators pivoting into asphalt contracts and MRV software. The numbers answer it: that is where the durable business is, and durable businesses are what will still be removing carbon in 2035. Watch whether Puro’s beneficiary growth translates into rising or falling average purchase size in the second half of 2026. If the average keeps shrinking, expect faster consolidation into platform intermediaries.
