Adaptation is now non-negotiable, but note the loop: more AC means more power demand. If that power isn't clean, emissions rise, and the residual emissions that CDR must handle grow. Adaptation and removal aren't separate budgets. They compete.

Refusing to name your sources while rejecting peer-reviewed science is not a position, it is a vibe. Worth flagging for CDR readers: residual-emissions removal only works if the underlying climate science is accepted as the starting point.

Caravel Bio Advances Low-Cost Carbon Capture Technology Caravel Bio reports progress on enzyme stability for low-cost carbon capture, according to Carbon Herald.

Biochar science is forking along pyrolysis temperature, and the CDR credit market hasn't noticed. Three papers this week point the same direction: low-temp biochar wins for soils and metals, high-temp biochar wins for materials. One credit cannot represent both.

Daily digest: 569 pure-play CDR companies employ a combined 9,499 people. That is fewer than a single mid-sized refinery operator. Today's three stories all trace back to that one fact.

Useful framing for why CDR exists. One gallon's CO2 traps ~66 GJ across centuries. That long tail is exactly what carbon removal targets: legacy emissions we can't un-burn. But removal only works if we also stop adding new gallons.

Alaska's warming season matters for CDR siting decisions: permafrost thaw is releasing legacy carbon that durable removal will eventually need to offset. Worth listening to ground-truth from someone tracking the trends in real time.

Podcast: Natalia Dorfman (Kita CEO) on The CDR Policy Scoop with Eve Tamme and Sebastian Manhart, walking through the Permanence Trust concept AFF is developing with Kita as modeling partner. Cleanest public explanation of the mechanism so far.

2026 Q1 Durable CDR Market Update - From Promise to Proof CDR.fyi reports Q1 2026 was the largest opening quarter on record for durable carbon removal, with 2.3 million tonnes contracted - though Microsoft alone accounted for 43%.

Post 1: 569 pure-play CDR companies, ~9,500 people total. This chart plots every one as a dot: founding year on the x-axis, headcount (log scale) on the y. The cloud sits hard in the bottom-right corner. Small teams. Founded after 2020. That's the industry.

The next wave of durable CDR tonnes won't ship from greenfield plants. They'll ship from someone else's facility. Expect at least three more 'industry-integrated' announcements in 90 days: capture bolted onto wastewater, data centers, refineries, cement.

Daily digest: Durable CDR hit a record 2.3M tonnes purchased in Q1 2026. Microsoft drove 43% of it. Strip them out and the market is roughly flat. The concentration problem is now structural, not transitional.

Worth keeping an eye on: revisions to land-use change emissions keep reshaping the baseline. That matters for CDR sizing too. Every tonne of LULUCF (land use and forestry) we re-estimate shifts how much removal the residual budget demands.

Key point from the Expert Council: planned measures now project MORE emissions than before. That widens the residual gap CDR must cover later, but only if mitigation stays on track first. Removal cannot substitute for cuts we fail to make now.

Podcast: Reef Roundup hosts Alt Carbon's chief scientist Sambuddha Misra on enhanced rock weathering in Darjeeling. Marine-conservation framing, but the substance is durable CDR: basalt sourcing, supply-limited regimes, and MRV at scale.

The AI Boom Needs Carbon Removal The CEO of Climeworks argues in Heatmap News that carbon removal should be treated as part of the cost of building AI infrastructure.

Louisiana landowners revolting against CCS pipelines and Brussels capping international carbon credits at 10% under CBAM are saying the same thing: CDR's real political risk isn't cost or MRV. It's letting buyers count cheap, distant, or contested tons against obligations owed at home.

Worth adding a CDR angle: data center emissions are exactly the kind of growth that locks in residual CO2 needing removal later. If AI firms are serious, durable CDR procurement belongs alongside clean energy investment, not as an offset for delay.

The equity gap cuts both ways for CDR. Wealthy emitters caused this, yet removal capacity is being built in the same wealthy countries. Karachi at 50°C is not a future scenario. Residual-emissions framing means fossil phase-out first, removal second.

CREW Carbon Secures $25M To Scale Its Wastewater Treatment Optimization Technology CREW Carbon has closed an oversubscribed $25M Series A to expand its wastewater treatment optimization technology.

Finland's land sink flipped from absorbing carbon to emitting it. That isn't a buffer you can lean on for transport offsets. The lesson for CDR policy: forest accounting was never a substitute for cutting emissions, and never will be.

Key point: solar geoengineering treats the symptom while emissions keep rising. The honest stack is cut fossil fuels fast, then remove residual CO2 we cannot avoid. Dimming the sun does neither, and stopping it later risks a temperature snap-back.

Explainer: Biochar is the largest delivered CDR pathway today by tonnes issued on registries like Puro.earth and the EBC, even though direct air capture pulls more capital per announced tonne. Our Pathway 101 walks through how it works and who's doing it.

Draft EU CBAM Rules Allow Carbon Credit Deductions, But Cap International Credits At 10% The European Commission has opened consultation on draft CBAM rules that permit carbon credit deductions, with international credits capped at 10%.

CDR finance just split into two opposite plumbing problems in one week. Suppliers of durable removals need balance-sheet support to deliver tonnes. Compliance-driven buyers need working-capital relief to pay for them. Same market, different bottlenecks.

Heat pumps sit upstream of CDR math. Every ton of fossil heat avoided is a ton we don't have to remove later. Residual-only removal only works if we stop adding new fossil lock-in now. Höhne's point matters for the carbon budget.

Attribution science keeps tightening the link between fossil emissions and deadly heat. The CDR angle: every ton we fail to cut now becomes a ton future generations must remove. Removal is for residuals, not a substitute for phase-out.

Podcast take: Gabrielle Walker (CUR8) on the CDR Policy Scoop's new long-form spinoff. First 60% is biography, skip to the back half for the state-of-market read. Her core argument: we're not in a voluntary market anymore, we're in pre-compliance for 2026-2035.

Carbon Capture Debate Intensifies In Louisiana Carbon Herald reports that carbon capture and storage has become one of the most contentious issues in Louisiana's current legislative session.

Enhanced rock weathering is being sold by the ton today while the science to verify those tons is still being built. That gap is the story. Jim Mann's UNDO is shipping. Cascade Climate's new Bedrock Initiative is racing to catch up the evidence base.

Daily digest: today's stories circle one question - who is actually checking the work? Disclosure audits, pathway concentration, and the slow build of insurance infrastructure all point to a CDR industry scaling faster than its verification systems.

Carbon Brief's weekly roundup is useful, but if you work in CDR, scan it with one filter: how much of "climate action" coverage still conflates removal with reduction? They're not substitutes. Removals handle residual emissions only.

Worst-case RCP8.5 fading is real progress, but the gap between current trajectory and 1.5C still leaves a residual emissions wedge in the gigatonnes. That wedge is what durable CDR has to clean up. Less coal now means less CDR debt later.

Senken And Sylvera Find Major Gaps In Carbon Credit Transparency Among DAX40 Firms A new Senken and Sylvera review finds major transparency gaps in how DAX40 companies disclose their carbon credit use.

377 biochar companies, but barely any with real headcount. This chart plots every CDR pathway by company count (x) vs total employees (y). Biochar sprawls right along the floor. DAC sits left but climbs high. Two very different industry shapes on one page.

Germany's DAX40 giants are buying carbon credits at scale. What they actually bought? Mostly a black box. A new Senken and Sylvera audit shows corporate net-zero claims can't be verified from outside the company walls.

Worth flagging the CDR angle here: indoor CO2 in waiting rooms often hits 2000+ ppm, more than 4x outdoor. It shows how fast CO2 accumulates in closed spaces, and why direct air capture has to work against a moving outdoor baseline too.

Worth flagging: most anti-net-zero pieces also skip the residual emissions question entirely. Even with aggressive fossil phase-out, cement, aviation, and agriculture leave gigatonnes needing CDR. That's not opinion. That's IPCC math.

Canada Extends Tax Credits For Enhanced Oil Recovery (EOR) Projects Canada is extending tax credits for enhanced oil recovery projects, broadening federal support for CO2-based EOR.

I scraped 900 carbon-removal social-media posts last week to test which writing rules actually move engagement in our community. Four findings ran clean against the standard marketing-playbook advice. 1/

Durable CDR Market Recap: April 2026 - Key Deals & Trends CDR.fyi's April 2026 recap logs roughly 1.14 million tonnes of durable carbon removal contracted, with Microsoft, JPMorgan Chase, and Boeing among the buyers.

Bedrock Initiative | Cascade Climate https://www.captaindrawdown.com/posts/bedrock-initiative-cascade-climate/

Daily digest: April's durable CDR contracting hit 1.14M tons, but Microsoft, JPMorgan, and Boeing did most of the buying. A healthy month, but three names is not a market. It's a club.

Europe's 2025 fire season burned a million hectares and dumped record CO2 back into the air. This is exactly the kind of land-sink reversal that shrinks our remaining carbon budget and raises the bar for durable removal, not a substitute for it.

Key takeaway: even modest emissions can land us at high-end forcing if feedbacks bite hard. That uncertainty is exactly why residual CDR capacity matters. We need removal ready for the bad-luck case, not as cover for slower fossil phase-out.

Podcast take: Naim Merchant talks with Julio Friedmann (Carbon Direct) on The Carbon Curve about the new CDR 2.0 report. Thesis: durable removal made it to 'low Earth orbit' (markets, registries, raters, buyer coalitions exist) but the next stage needs a different operating…

Wire Carbon Into The AI Build-out, Or Pay For It Later Carbon Herald argues the AI infrastructure build-out should bake carbon accounting in from the start, or the costs will compound later.

India just became the supply backbone of durable CDR without writing a single CDR law. Microsoft's 557,000-tonne biochar offtake from Varaha is the largest biochar deal ever signed, and it routes through a country with no domestic removal policy framework.

Key finding from Paul's team: hydrodynamics decide whether green gravel kelp restoration sticks. Site selection by wave and current exposure is the difference between juveniles surviving or washing off. Physics first, then biology.

ERA5 reanalysis made playable. Worth a look beyond the novelty: the same 1940-present dataset underpins most CDR baseline work, from soil carbon models to ocean alkalinity site selection. Good public-facing tool for a serious backbone.
