CDR Week and notes

Take: CBAM and International Credits: What’s Just Changed? - with Dan Maleski

Take on a podcast episode from The CDR Policy Scoop, originally published Fri, 15 Ma. Listen: https://shows.acast.com/the-cdr-policy-scoop/episodes/cbam-and-international-credits-whats-just-changed-with-dan-m TL;DR Draft Carbon Border Adjustment Mechanism implementing act (published 13 May 2026) lets importers deduct carbon costs paid abroad — including, controversially, international credits. First-time clarity worth knowing. Hard cap: international Article 6 credits can offset at most 10% of a CBAM liability. But most third-country ETSs already cap offset use at 5-10%, so binding impact is modest. No quantitative cap on domestic credits used inside a third-country mandatory regime. Maleski can’t justify the asymmetry; nor can the hosts. Genuinely odd policy choice. “Effective” carbon cost is net of free allocation — so Brazil, Turkey, Korea ETSs in ramp-up phase deliver near-zero deduction regardless of headline carbon price. Important reality check. Anti-gaming safeguard is “independent persons” verifying paid prices. Maleski openly notes clients ask how to inflate intra-group credit prices. Thin guardrail. The CDR Policy Scoop (episode link) reconvened Dan Maleski of Ruby Advisors one day after the Commission dropped its draft implementing act on Article 9 of CBAM — the provision letting importers deduct carbon costs already paid in the country of origin. Sebastian Manhart and Eve Tamme spend 30 minutes parsing what the act actually says about international credits, the 10% cap, and why the consultation (closing early June) still leaves big pieces missing. ...

569 pure-play CDR companies share just 9,499 employees

This violin plot sorts every pure-play CDR company in the Directory by its pathway (columns) and its headcount (vertical axis, log scale from 1 to 100+). Each dot is one company, coloured by its current liveliness tier — Active, Moderate, Suspect, or Likely Dead. The grey shape behind each column is the size distribution: where it bulges, that’s where most companies in that pathway sit. The value here is comparative. A raw company list tells you who exists; this view tells you where the weight sits. Pathways with most dots stacked at the bottom are dominated by sub-10-employee firms — many small entrants, few that have grown. Pathways with dots reaching up the column have produced operators that scaled past the founder-and-a-few-engineers phase. Colour (not vertical position) is what tells you the health story: red dots high up the column mean a sizeable operator went quiet; red dots on the floor are the long tail churning as it always has. ...

CCS Gets Its Own Carbon Certificates: Mitchell Foundation Opens 60-Day Review

Carbon Herald just published Foundation Opens Consultation On CCS EACs Methodology. Carbon Herald reports that the Cynthia and George Mitchell Foundation has launched a 60-day public consultation seeking stakeholder input on a draft methodology for carbon capture and storage Environmental Attribute Certificates (EACs). The framework is intended to standardize how captured and stored CO2 can be tracked and credited through tradable certificates, similar in concept to renewable energy attribute systems. The consultation invites feedback from industry, researchers, NGOs and policy groups before the methodology is finalized. The piece situates the effort within broader work to build credible market infrastructure for CCS deployment and accounting. ...

Captain's CDR Log #141: One skeptic, one number, and the 1000x gap modelers keep assuming away

Captain Drawdown’s daily logbook on every CDR story, paper, and expert voice — so you don’t have to read them all. 1,000×. That is the gap between durable carbon removal we are actually delivering today and what the median IPCC 2°C scenario quietly assumes we will be removing each year by 2050. The prior reference point most CDR boosters cite is purchases, not deliveries. CDR.fyi’s Q1 2026 market update puts cumulative durable purchases near 10 Mt and calls Q1 the largest quarter on record. That framing flatters the sector. Switch the denominator to tonnes physically delivered and verified, and the annual run rate sits under 1 Mt/yr. IPCC scenarios consistent with 2°C require 5 to 10 GtCO₂/yr by 2050. One million versus five to ten billion. Three orders of magnitude on the delivery line, four on the cumulative line. ...

Pathway 101: Enhanced Weathering

The pathway Enhanced weathering (EW) accelerates a chemical reaction that the Earth already runs at geological pace: the dissolution of silicate rocks by carbonic acid in rainwater. When fast-weathering rocks like basalt, olivine, or wollastonite are crushed to fine particles and spread — usually on cropland, sometimes in rivers, forests, or mine pits — the surface area available for reaction increases by orders of magnitude. CO₂ dissolved in soil water reacts with the minerals, producing dissolved bicarbonate ions that drain through soils to groundwater and eventually the ocean, where the carbon is stored on timescales of 10,000 to 100,000+ years. That long-tailed durability is why EW sits alongside direct air capture and mineralization in most “durable CDR” portfolios, even though it borrows infrastructure (quarries, ag spreaders) from existing industries. ...

Caravel Bio boosts enzyme stability in low-cost carbon capture push

Carbon Herald just published Caravel Bio Advances Low-Cost Carbon Capture Technology. Carbon Herald reports that US startup Caravel Bio has made gains in stabilizing the enzymes it uses for carbon capture, a step the company frames as central to lowering the cost of biologically assisted CO2 removal. Enzymatic approaches typically rely on carbonic anhydrase or similar biocatalysts to accelerate CO2 absorption into solvents, but degradation under industrial conditions has been a long-standing barrier. The outlet positions Caravel’s work as part of a wider push to bring biological capture methods closer to commercial deployment alongside conventional amine-based systems. ...

Captain's CDR Log #140: Three new biochar papers expose a pyrolysis-temperature fork the credit market ignores

Captain Drawdown’s daily logbook on every CDR story, paper, and expert voice — so you don’t have to read them all. Three biochar papers landed this week that, read together, expose a fork in the road the credit market is pretending isn’t there. Pyrolysis temperature, not feedstock or region, is becoming the variable that decides what biochar actually is: a durability-first carbon sink, or a functional soil and industrial input. You cannot have both at full strength, and current credit methodologies price them as if you can. ...

CDR Daily Digest — 2026-05-19

The CDR industry is still tiny, and that shapes everything else Today’s three stories point to one underlying fact: pure-play carbon dioxide removal is a very small industry trying to deliver very large promises. Across 569 pure-play CDR companies, total headcount sits at just 9,499 people. That is fewer employees than a single mid-sized refinery operator. It explains why durable tonnes are increasingly shipping from facilities the seller does not own, and why Alberta thinks it can rewrite its carbon market without much pushback from removal buyers. ...

569 pure-play CDR companies share just 9,499 employees

This chart plots every pure-play CDR company in the Directory as a single dot. The horizontal axis is the company’s founding year (estimated from its primary domain registration), the vertical axis is its current headcount on a log scale, and the colour codes the company’s pathway. The shaded blue background traces overall company density — darker patches mark where the crowd of pure-plays sits. The value here is shape, not ranking. A bar chart would tell you how many companies exist in each pathway; this view tells you the entire industry’s growth contour at one glance — when did the wave of small startups hit, where are the rare big older operators, what cluster sits on the floor of “still under five people”. Outlier dots near the top of the chart are the names everyone already knows; the dense low band is where most of the industry actually lives. ...

Alberta carbon market revamp could unlock new Pacific oil export pipeline

Carbon Herald just published New Alberta Carbon Market Deal Could Clear Path For Pacific Oil Export Route. Carbon Herald reports that Canadian Prime Minister Mark Carney and Alberta Premier Danielle Smith have agreed to overhaul Alberta’s industrial carbon pricing system. The deal links carbon market reforms to a broader package that could pave the way for a new oil pipeline carrying Alberta crude to the Pacific coast for export. The arrangement is positioned as a compromise between federal climate policy and provincial energy ambitions, tying continued carbon pricing stability to infrastructure approvals. Details on credit pricing floors, compliance timelines, and the specific pipeline route are part of the negotiated framework outlined in the article. ...
