SBTi's refusal to let removals substitute for cuts is CDR's biggest demand block

Marginal Carbon just published The main thing holding carbon removal back. Robert Höglund writes that voluntary demand for durable carbon removal is capped because corporate standards reserve it for residual emissions only. Under SBTi rules, CDR cannot substitute for other mitigation options such as biofuels or CCS, and is allowed only after steep gross reductions - roughly 91% for general Scope 3, 97% for aviation, and 100% for shipping. He contrasts this with the EU Commission’s new ETS proposal, which treats durable removals as equivalent to emission reductions rather than limiting them to hard-to-abate categories. Höglund notes an asymmetry: companies can over-rely on biofuels or CCS beyond what pathways model and stay compliant, while CDR is categorically excluded from target implementation. ...

Charm Industrial lands J.P. Morgan debt deal to scale bio-oil carbon removal

Heatmap News just published Transcript: What Barbecue Sauce Has in Common With Carbon Removal. Heatmap News has published the transcript of a Shift Key episode featuring Peter Reinhardt, CEO of Charm Industrial. Host Robinson Meyer frames the conversation around wildfire risk in the US, noting that roughly 1.6 million acres of forest were burning at the time and that accumulated dead fuel raises fire likelihood. Charm’s model converts biomass, including material from forest fuel clearing, into bio-oil that is injected underground for durable carbon removal. The episode covers Charm’s recent agreement with J.P. Morgan, under which the bank committed to purchase more than 60,000 tons of removal and extended a $20 million debt facility to the company. Reinhardt’s broader background across climate tech ventures also comes up. ...

569 pure-play CDR startups employ just 9,525 people worldwide

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. ...

EU Proposes 250 Mt of Permanent CDR in ETS — a Breakthrough for Carbon Removal

DVNE just published : EU Emissions Trading: Breakthrough for CDR. DVNE reports on the European Commission’s proposal to revise the EU Emissions Trading System, which would for the first time bring carbon dioxide removal into the bloc’s compliance market. Up to 250 million tonnes of permanent, domestic removals are to be integrated between 2030 and 2040. Eligibility would initially be limited to CRCF-certified DACCS and BioCCS projects, with other pathways left to future review cycles. The Commission would procure removals centrally, financed by auctioning additional EU Allowances, using a cost-optimised portfolio approach with payment on delivery. DVNE frames this as a shift from voluntary market financing toward long-term regulatory demand, giving developers and investors greater planning certainty, while noting that refinements will be needed during negotiations. ...

EU Proposes Buying 250M Tonnes of Permanent CDR With ETS Auction Proceeds

CDR.fyi just published The EU ETS Proposal Explained. CDR.fyi analyses the European Commission’s proposal to amend the EU Emissions Trading System under a new Article 9c. The plan would auction 250 million additional EU Allowances and use the revenue for central procurement of permanent removals, initially naming BioCCS and DACCS as eligible methods. Individual emitters would not be able to surrender removals in place of allowances; instead the Commission would run a public procurement programme within the ETS architecture. The piece stresses that the 250 Mt figure is a ceiling on demand, not a signed order, since adoption, eligibility rules, funding, contracting and delivery all remain open. It also highlights the principle that removals used against fossil emissions must offer like-for-like durability. ...

CDR Daily Digest — 2026-07-23

CDR is professionalizing on every axis at once, and every axis shows the same shape: fast growth on the surface, churn and concentration underneath. Today’s six stories cover talent, company formation, policy, and technology, and the pattern repeats in each. The field is bigger than it has ever been. It is also more lopsided than the headline numbers suggest. The workforce tripled. It also leaks. The CDR Researcher Census shows the active research workforce has tripled to roughly 32,000 people. That is the good half of the story. The other half: the pool of dormant researchers, people who published in CDR and then stopped, grew even faster than the active count. ...

Take: #5: maybe CDR is a good decision that just feels bad right now.

Take on a podcast episode from Carbon Removal Newsroom, originally published Tue, 21 Ju. Listen: https://climateworkersanonymous.substack.com/p/5-maybe-cdr-is-a-good-decision-that TL;DR Not an interview: two anonymous written submissions from CDR practitioners, read aloud by curator Ross Kenyon. Sentiment data, not market data. Submission one names the current mood — Microsoft pausing, buyer scarcity, VC pullback, quiet consolidation — then argues second-time founders re-entering is a real signal. Submission two calls for cutting 2050 novel-CDR targets to 2–3 gigatons and abandoning the “compensate for residuals” framing entirely. Provocative, worth arguing with. The “reverse legacy damage, don’t offset ongoing emissions” reframe is the most substantive idea here — it has real implications for credit-market design. Twenty minutes, no numbers you can cite in a memo, but an unusually honest read on practitioner psychology. Climate Workers Anonymous #5 is not a normal podcast episode. Ross Kenyon (formerly of Nori and Carbon Removal Newsroom) curates anonymous submissions from climate workers, PostSecret-style, and this installment carries two longer analytical pieces from people evidently inside carbon dioxide removal. There’s no guest, no dataset — just what practitioners will say when their names aren’t attached. ...

Take: Removals Enter the EU ETS: What Brussels Actually Proposes - with Mette Quinn

Take on a podcast episode from The CDR Policy Scoop, originally published Wed, 22 Ju. Listen: https://shows.acast.com/the-cdr-policy-scoop/episodes/removals-enters-the-eu-ets-what-brussels-actually-proposes-w TL;DR The European Commission confirms a commitment to buy 250 Mt of permanent, domestic removals (bioenergy with carbon capture / direct air capture) for the EU Emissions Trading System — with a 2034 review clause. Commission cost modeling assumes no national subsidies layered on top. Given Nordic BECCS economics today, that looks optimistic. ETS operators can use certified removals for their own compliance from 2031 — no volume cap beyond deduction from the 250 Mt. Pay-on-delivery is the default, but Quinn signals openness to prepayment and offtake structures via Innovation/Modernisation Fund mechanics. Details unwritten. Commission’s own supply projection: ~48 Mt/year by 2040. The gap to the headline target is the real story. Eve Tamme and Sebastian Manhart got Mette Quinn — Deputy Director for Carbon Markets and Clean Mobility at DG CLIMA, and the official who led the ETS revision — on The CDR Policy Scoop five days after the Commission published the proposal. This is the closest thing to primary-source commentary you’ll get on the removals provisions right now. ...

Take: Sustaera - electric DAC

Take on a podcast episode from Reviewer 2 does geoengineering, originally published Sat, 04 Ap. Listen: https://podcasters.spotify.com/pod/show/reviewer2geoengineering/episodes/Sustaera---electric-DAC-e3heke1 TL;DR Sustaera embeds Joule heating directly into a monolithic sorbent structure using a carbon-based resistor — no steam, no gas-phase heat transfer. Claims >90% heating efficiency in a 3.4L lab prototype. Sorbent is alkali carbonate on alumina, not amine: claimed 18,000–24,000 cycles (~3 years) before 30% degradation forces recoating. If real, that’s a meaningful operating-cost lever. Full adsorption/desorption cycle in 30–45 minutes; desorption at just 80°C, ramping in seconds. Host pushes back hard on whether this actually meshes with curtailed-power economics — worth hearing both sides. Manufacturing piggybacks on catalytic-converter production lines. Buried at the end of the episode, but arguably the most important claim. technology readiness level (TRL) 5 (1 t/yr indoor), raising $8.6M for a first 500–750 t/yr outdoor unit against $700/t pre-purchases from Stripe and Shopify. Andrew of Reviewer 2 Does Geoengineering interviews Corey Sanderson, CTO and co-founder of Sustaera, the North Carolina direct air capture (DAC) startup that spun out of incubator Sustion in 2021. It’s a proper technical grilling — sorbent chemistry, desorption physics, cycle economics — from a host who knows his physisorption from his chemisorption. Episode here. ...

569 pure-play CDR companies employ just 9,525 people

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. ...
