Biochar leads CDR with 377 companies but Enabling Tech employs 7,700

Each dot on this scatter is a single CDR pathway - direct air capture, enhanced rock weathering, biochar, ocean alkalinity, mineralization, and the rest. The horizontal axis counts how many companies are working that pathway; the vertical axis sums the employees across those companies. Linear scales on both, so distance on the page matches distance in the numbers. What this view reveals that a headcount table cannot is the shape of the industry. A pathway sitting high and to the right is crowded with firms and staffed deeply. One sitting high but to the left is a pathway dominated by a few large companies. Low and to the right means many small teams chasing the same idea. The spread between these corners is the story of where capital and talent have actually landed, versus where the field is still a cottage. ...

Soil carbon dominates CDR with 15,849 active researchers in 2025

This chart tracks Soil Carbon researchers over time on a diverging axis. Above the line are researchers who published a Soil Carbon-relevant paper that year (active); below the line are dormant researchers, split into those who published the previous year and those who published only earlier. New entrants join at the base of the active band each year as a teal block. Soil Carbon is the largest pathway by headcount, sitting closest to mainstream soil science. The top envelope is the number actually publishing in the pathway each year. ...

569 pure-play CDR startups employ just 13,571 people

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. ...

Take: Canada's Next Industrial Play: A New Revenue Line for the Mill

Take on a podcast episode from The Carbon Curve, originally published Thu, 10 Se. Listen: https://carboncurve.substack.com/p/canadas-next-industrial-play-a-new TL;DR Mercer’s Peace River pulp mill is developing a BECCS project with Svante that could store ~500,000 tonnes CO2/year — FID still ~a year out. Alberta’s stack (15 km to sequestration, CCUS ITC + provincial top-up, permitting precedent) is doing real work here — worth noting for site selection debates. Mercer wants BECCS bumped to the 60% ITC tier that DAC gets, plus a CDR price floor. Legitimate ask, but “we need a backstop” tells you unit economics don’t yet close on voluntary demand alone. Meadow Lake’s Northstar (majority Indigenous-owned, 90 kt/yr, 15-year 626 kt Microsoft offtake) is the most structurally interesting BECCS deal in Canada right now. Sheila Harrison’s point lands: without a viable primary forest sector, there’s no host infrastructure for pulp-mill BECCS. Fibre security is a CDR risk factor, not just a forestry one. Na’im Merchant’s second episode in the Canada’s Next Industrial Play miniseries goes into the forest products sector with three guests: Bill Adams (CSO, Mercer International), Sheila Harrison (VP Policy, Alberta Forest Products Association), and Tina Rasmussen (CBO, MLTC Industrial Investments). The episode is essentially a pulp-mill BECCS deep dive with a policy and Indigenous-ownership wrapper. Episode link. ...

Take: Live From Brussels: The Carbon Removal Policy Summit - with Rodica Avornic

Take on a podcast episode from The CDR Policy Scoop, originally published Wed, 16 Se. Listen: https://shows.acast.com/the-cdr-policy-scoop/episodes/live-from-brussels-the-carbon-removal-policy-summit-with-rod TL;DR Live from Carbon Gap’s first Carbon Removal Policy Summit in Brussels — four governance levels (international, EU, national, local) as the frame. EU “Buyers Club” is now the “Buyers Coalition” — open, not membership-based — and being positioned as a test ground for a future Emissions Trading System purchasing facility, possibly by 2029. Carbon Gap dropped a Policy Levers Library (~165 levers) plus a forthcoming Foundations of Carbon Removal book. Genuinely useful reference infrastructure if it lands as demoed. Real unresolved problem surfaced: Carbon Removal Certification Framework credits don’t yet map to national greenhouse gas inventories under IPCC methods. Without that link, Member State targets can’t pull on CRCF supply. Achim Steiner’s line — removals concentrated in few buyers, few countries, few technologies — is the honest diagnostic of where European durable carbon dioxide removal (CDR) actually sits. Sebastian Manhart and Eve Tamme record live from Brussels across two days of Carbon Gap’s inaugural Carbon Removal Policy Summit, with a mid-day sit-down with Carbon Gap policy director Rodica Avornic. The episode is a running commentary on what got said on stage — Buyers Coalition futures, ETS integration guardrails, post-2030 Member State targets, and the awkward plumbing between CRCF credits and national inventories. ...

Podcast take: Which story is carbon dioxide removal actually in?—w/ Rudy Krehbiel of EcoEngine

Take: Which story is carbon dioxide removal actually in?—w/ Rudy Krehbiel of EcoEngineers

Take on a podcast episode from Reversing Climate Change, originally published Thu, 17 Se. Listen: https://podcasters.spotify.com/pod/show/reversingclimatechange/episodes/Which-story-is-carbon-dioxide-removal-actually-in-w-Rudy-Krehbiel-of-EcoEngineers-e3ovfja TL;DR Krehbiel argues CDR is still at the innovator stage, not in a hype-cycle trough — useful reframing if you buy his diffusion-curve lens. Numbers cited: <50Mt contracted, ~2Mt delivered, Microsoft ~78% of disclosed volume, median non-Microsoft biochar purchase <100t. Consistent with public CDR.fyi data. Core argument: CDR is a public good with diffuse, delayed, non-excludable benefits — venture-scale expectations may be the wrong operating system for building it. Worth chewing on. Three-layer de-risking frame (financial / buyer / societal) is the most portable takeaway for operators. Long detour into Whig-theory-of-history, AfD, and Charlie Kaufman films — signal-to-ramble ratio is not great. Skim-friendly. Ross Kenyon hosts EcoEngineers’ Rudy Krehbiel for a meandering two-hour conversation about which narratives the CDR industry is unconsciously operating inside — diffusion curves, Moore’s Law analogies, compliance-market inevitability — and which ones will not survive contact with 2026 politics. Episode link. It is more meta than technical, but Krehbiel earns his airtime. ...

Enabling tech dwarfs CDR with 7,700 workers versus 13,571 pure-play producers

This chart is a stacked horizontal bar showing CDR-attributable headcount across pathways on the vertical axis, with each bar segmented by business focus: pure-play companies whose entire reason for existing is CDR, divisions inside larger firms where CDR is one line of business, and “ecosystem” firms, the directory’s label for companies that sell tools, verification, brokerage, or software to those operators. Bar length is total attributed workers; the color split is where those workers actually sit. ...

CDR Industry Update - September 2026

CDR Industry Update - September 2026 A quiet month on the headcount, a busy one under the hood: 114 existing companies edited, zero net additions or removals. The directory held flat at 1,470 active companies this month, the first time in over a year we’ve seen a true zero on both the add and remove columns. That is worth pausing on. Through 2024 and most of 2025 we tracked steady monthly churn in the 15-40 range on each side, with the net often positive by single digits. September broke that rhythm entirely. ...

Pathway 101: Additionality & Baselines

Additionality & Baselines: The Counterfactual That Decides Whether a Tonne Is Real Every carbon dioxide removal (CDR) credit is, at bottom, a claim about a parallel universe. Additionality asks whether the tonne of CO₂ subtracted from the atmosphere would have been subtracted anyway, absent the credit revenue. Baselines are the quantitative expression of that parallel universe: the reference scenario against which “extra” removal is measured. Get the baseline wrong and everything downstream — the price, the corporate net-zero claim, the registry’s reputation — is built on a number that doesn’t correspond to any physical reality. This is why buyers doing serious diligence spend more time on counterfactual assumptions than on capture chemistry, and why what “net zero” actually means depends on the integrity of the removals it invokes. ...

569 pure-play CDR companies and most red dots are tiny

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. ...
