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. ...

Castorone Begins Laying UK's First Offshore CO2 Pipeline in North Sea

Castorone Begins Laying UK's First Offshore CO2 Pipeline in North Sea

Carbon Herald just published Offshore Heavyweight Castorone Arrives In North Sea To Lay Crucial CO2 Pipeline. Carbon Herald reports that the Northern Endurance Partnership has started heavy offshore work on a CO2 transport pipeline in the UK North Sea, a key piece of infrastructure for Britain’s industrial decarbonization plans. The arrival of Saipem’s Castorone, one of the largest pipelay vessels in operation, marks the start of the subsea installation phase. The pipeline is intended to move captured CO2 from Teesside emitters to permanent offshore storage as part of the East Coast Cluster. The project is a central element in the UK government’s CCS deployment strategy and its funding commitments to the sector. ...

Captain's CDR Log #248: 250 million allowances is the number that changes who the CDR buyer of last resort actually is

Captain Drawdown’s daily logbook on every CDR story, paper, and expert voice — so you don’t have to read them all. 250 million. That is the count of EU Emissions Trading System allowances the Negative Emissions Platform is campaigning to have redirected, by value, into permanent carbon removal purchases. The prior reference point is not another ETS proposal. It is the sum of every national CDR support cheque Europe has written to date. Finland is weighing a €23M subsidy for industrial biogenic capture. Alberta, outside Europe but a useful peer, just allocated $20M to hydrogen and carbon capture from its TIER fund. These are the cheques CDR developers currently model against. The NEP proposal is a different unit of account. ...

Captain's CDR Log #247: Five people, five hard numbers, one week that moved past the overshoot debate

Captain Drawdown’s daily logbook on every CDR story, paper, and expert voice — so you don’t have to read them all. This week’s numbers were set by named people making specific commitments, not by panels debating overshoot in the abstract. Five figures. Five decisions. A pattern worth logging. $2.3 million — Zeke Hausfather, climate research lead at Frontier Climate, announced four research grants for ocean alkalinity enhancement science. In his words, the money is meant to “help answer some of the big scientific questions needed to enable safe and scalable ocean alkalinity enhancement.” Zeke Hausfather (@zekehausfather.com on Bluesky) is putting Frontier Climate’s dollars directly on secondary precipitation and measurement, reporting and verification (MRV) - the two questions OAE preprints keep flagging as blockers. ...

CDR Daily Digest — 2026-09-03

CDR Daily Digest — 2026-09-03

Alberta put $20 million of industrial carbon-price revenue on the table today for hydrogen and carbon capture scale-up. That single line captures the day’s tension. Public CDR money is still flowing, but the conversation around it, from Wendell Berry to Grant Faber to the UNEP framing of removals, is getting sharper about what that money is actually buying. Alberta’s TIER bet, and what it signals Alberta’s TIER fund, the pool built from the province’s industrial carbon price, is directing $20 million toward hydrogen and carbon capture projects. TIER money is one of the few sources of public capital in North America that comes directly from emitters paying for their tonnes, so where it lands matters as a signal of what provincial regulators think will scale. ...

Podcast take: Removals, avoidances, and what Wendell Berry thought of making tonnes fungible

Take: Removals, avoidances, and what Wendell Berry thought of making tonnes fungible

Take on a podcast episode from Reversing Climate Change, originally published Thu, 03 Se. Listen: https://podcasters.spotify.com/pod/show/reversingclimatechange/episodes/Removals--avoidances--and-what-Wendell-Berry-thought-of-making-tonnes-fungible-e3o9d89 TL;DR Ross Kenyon’s solo reflection on Wendell Berry’s death, wrapped around an essay he wrote for Removr on removals vs. avoidances in one portfolio. Mea culpa: Nori tried to build a “better” registry from scratch; Kenyon now says the convergence of legacy registry designs is structural, not a willpower failure. Useful concession. Argues durable CDR’s cultural separatism from the broader voluntary carbon market has become a liability, not a moat. Fair, and increasingly the consensus. Would pick rainforest protection over carbon removal if forced to choose. Provocative framing, thinly defended. Name-checks Martin Freimüller (Octavia) and Robert Höglund as CDR-side voices moving toward portfolio thinking. Signal for where the discourse is drifting. Ross Kenyon, Nori cofounder and long-running host of Reversing Climate Change, delivers a solo episode (link) that pairs an obituary for Wendell Berry with a piece he wrote for the Removr registry on why durable removals and avoidances belong in the same portfolio conversation. It’s part personal essay, part market commentary — you’ll get more of the former than the latter. ...

Take: Somebody here needs to say this before an investigative journalist does. I’d rather it be one of us.

Take on a podcast episode from Carbon Removal Newsroom, originally published Tue, 01 Se. Listen: https://climateworkersanonymous.com/p/11-somebody-here-needs-to-say-this TL;DR Anonymous submitter argues artisanal biochar gets a scrutiny pass that industrial projects don’t — and that gap is where bad actors are hiding. Sharp, overdue take. Specific red flag: daily production logs on public registries showing identical output across monsoon and dry season. Concrete, checkable, damning if true. dMRV (digital measurement, reporting, verification) providers check data completeness/format, not plausibility against public rainfall records. That’s a real registry gap. Water-for-quench competing with irrigation water in rain-scarce regions — a farmer-cost story the “farmer-first” crowd doesn’t tell. First ~15 minutes is Ross’s AI-doom monologue. Skip to the submission unless you want that too. Ross Kenyon’s Climate Workers Anonymous publishes anonymous submissions from climate workers. This episode’s submission is a pointed critique of artisanal biochar carbon credits from someone who’s clearly been reading registry data. The first ~15 minutes is Ross editorializing about artificial general intelligence and Stripe’s “singularity is here” investor memo — you can skip to the submission without loss. ...

Take: What is really happening to DAC Hubs? - with Grant Faber

Take on a podcast episode from The CDR Policy Scoop, originally published Tue, 01 Se. Listen: https://shows.acast.com/the-cdr-policy-scoop/episodes/what-is-really-happening-to-dac-hubs-with-grant-faber TL;DR Only ~2.5% of the original $3.5B DAC Hubs budget has been disbursed; contract negotiation ate most of the Biden term before terminations froze things. $1B of hub funding was reprogrammed by Congress to nuclear; ~$1.3B sits unobligated but not rescinded — dormant, not dead. DOE admitted in court that project terminations were chosen on political basis; cancellations skewed toward blue-headquartered primes even when projects sat in red states. Both TA3 megahubs (Project Cypress, South Texas) survived the retention list — Grant credits BIL/IRA’s deliberate red-district geography strategy. Grant’s speculative but useful scenario: unspent CDR appropriations pile up, and 2029 brings a sudden multi-billion-dollar “we’re back” moment. Take with salt. Grant Faber — former DAC Hubs program manager at DOE’s Office of Fossil Energy and Carbon Management, now Head of Standards at Absolute Climate — joins Eve Tamme and Sebastian Manhart on The CDR Policy Scoop to walk through his recent Substack article mapping the actual state of the US DAC Hubs program. This is the most granular public accounting of what survived, what got killed, and what’s still sitting in an account somewhere. ...

Alberta Stakes $20M From TIER Fund on Hydrogen and Carbon Capture Scale-Up

Alberta Stakes $20M From TIER Fund on Hydrogen and Carbon Capture Scale-Up

Carbon Herald just published Alberta Allocates $20M To Scale Hydrogen And Carbon Capture. Carbon Herald reports that the Government of Alberta has committed $20 million from its Technology Innovation and Emissions Reduction (TIER) fund to support the scaling of hydrogen and carbon capture technologies in the province. TIER is Alberta’s industrial carbon pricing system, and revenues from it are directed toward emissions reduction initiatives. The allocation is framed as part of Alberta’s broader strategy to build out lower-emissions industrial capacity, with hydrogen and CCUS positioned as central pillars. Full details on eligible recipients, project timelines, and selection criteria are covered in the original article. ...

Captain's CDR Log #246: The UNEP-era dismissal of CDR treats forests and silicates as the same bet

Captain Drawdown’s daily logbook on every CDR story, paper, and expert voice — so you don’t have to read them all. The new UN Environment Programme overshoot report is being read as a verdict: engineered carbon removal is unsafe or expensive, and cutting emissions with existing clean tech is already cheaper. Niklas Höhne (@niklashoehne.bsky.social) summarised it bluntly on Bluesky: “Technologien zur nachträglichen Entfernung von Kohlendioxid aus der Luft sind unsicher / sehr teuer.” That thread has travelled far this week, and it is becoming the political shorthand for CDR-in-general. Climate policy circles, EU ETS watchers, and a good chunk of the climate-science Bluesky crowd are nodding along. ...
