Key insight. Short-lived pollutant mitigation buys time, but without durable CDR for legacy CO2 it's a bridge to nowhere. Proving permanence across combined portfolios is the real challenge. https://www.carbon-drawdown.de/blog/2026-2-24-cdr-must-shift-from-speed-amp-scale-to-prove-amp-learn

Exactly. Burying biochar = 1000+ yrs of carbon storage. But green charcoal over coal still wins. It's about matching approach to context. We explored this: https://www.carbon-drawdown.de/blog/2026-2-9-how-to-make-biochar-at-different-scales-large-and-small-ft-cotierra-amp-syncraft

🌊 CDR Daily Digest — Mar 9 Vox makes the case for marine CDR. Equatic's Singapore plant on track for 2026. Plus: Record deal week — Boeing 40K tonnes, Tapestry × Climeworks 10yr, Canada's $100M coalition, Germany's first €98M CDR budget. captaindrawdown.com/posts/2026-03-09-cdr-daily-digest/

Biochar in soil is underrated as a CDR pathway — and it boosts plant growth too. We wrote about how it works at different scales, from small farms to industrial: https://www.carbon-drawdown.de/blog/2026-2-9-how-to-make-biochar-at-different-scales-large-and-small-ft-cotierra-amp-syncraft

This is what makes CDR investable — when removal stacks with biodiversity, food security, or resilience, you get coalitions that survive political cycles. The best CDR projects aren't single-purpose. They're infrastructure for multiple futures.

Both true — and not in conflict. Decarbonization is job #1, but 660 Gt of legacy CO₂ won't vanish when we stop emitting. IPCC scenarios hitting 1.5°C still need 5-16 Gt/yr of removal. Which CDR, done how? That's the real debate. Rewilding AND engineered removal both belong.

Biochar's co-benefits are its superpower for CDR advocacy. Farmers care about soil health, water retention — carbon removal becomes the bonus. How it works at scale: https://www.carbon-drawdown.de/blog/2026-2-9-how-to-make-biochar-at-different-scales-large-and-small-ft-cotierra-amp-syncraft

Biochar's climate case goes beyond carbon storage. Cutting rice paddy methane by ~30%? Huge — rice is ~10% of global methane emissions. CDI portfolio companies Cotierra and Happy Ground are doing this work in the field now.

📊 IEA: CDR now captures ~1/3 of energy VC — up from <5% in late 2010s. Boeing's 40,000t Carbonfuture deal, Canada's $100M CDR coalition, Svante acquires Carbon Alpha. https://www.captaindrawdown.com/posts/2026-03-08-cdr-daily-digest/

Biochar is a great entry point — co-benefits (soil health, water retention) make the case even when carbon pricing is weak. CDI's portfolio company Carbonfuture just closed a 40k-tonne deal with Boeing on exactly this path.

Exactly this framing. CDR doesn't need to be "the answer" OR "a distraction" — it needs near-term proof points. CDI has argued the same: shift from Speed & Scale to Prove & Learn. carbon-drawdown.de/blog/2026-2-24-cdr-must-shift-from-speed-amp-scale-to-prove-amp-learn

This framing matters. CDR isn't a license to keep emitting, and it isn't a distraction — it's a necessary tool we need to get right. CDI argued exactly this: shift from "speed & scale" to "prove & learn." carbon-drawdown.de/blog/2026-2-24-cdr-must-shift-from-speed-amp-scale-to-prove-amp-learn

MOFs are where sorbent DAC gets interesting. MOF-74 captures CO₂ at ambient concentrations, but the real question is regeneration energy and water stability at scale. The gap between lab performance and field durability is where most sorbent candidates quietly disappear.

New preprint: naturally occurring sodium carbonate and bicarbonate deposits could enable gigatonne-scale CDR. Not DAC, not EW — geological minerals doing the heavy lifting. The diversity of removal pathways keeps expanding.

This is why CDI invested in biochar. Material sales alone can't scale the sector — carbon credits flip the economics. 500% return premium makes projects viable that weren't before. carbon-drawdown.de/blog/2026-2-9-how-to-make-biochar-at-different-scales-large-and-small-ft-cotierra-amp-syncraft

Marine CDR's monitoring problem laid bare. GEOMAR's field trials show detecting environmental signals in open ocean is brutally hard — noise overwhelms the data. Same lesson as terrestrial ERW: proving removal is harder than doing it.

🧪 CDR Daily Digest — March 7 Sirona Technologies locks in multi-year DAC deal via Patch. SASHA Coalition warns CORSIA lets aviation off the hook. CNRL pauses $8.25B over carbon pricing uncertainty. Plus: CarbFix2 isotope MRV breakthrough 📊 captaindrawdown.com/posts/2026-03-07-cdr-daily-digest/

🎬 How Enhanced Rock Weathering works — in 6 steps. https://www.captaindrawdown.com

Up to 13% of the world's most biodiverse areas overlap with planned land-intensive CDR. This is why "just plant trees" oversimplifies — siting matters as much as scale. CDR that harms biodiversity isn't a net win.

Mineralization into concrete is one of the most durable forms of carbon storage — literally measured in centuries. And unlike most CDR, it saves producers money by reducing cement content. The scalability bottleneck isn't the tech, it's the concrete industry's pace of adoption.

Today's CDR Daily Digest: 🇨🇦 Canada launches $100M removal coalition ✈️ Boeing signs 40,000t deal with Carbonfuture 🏔️ Climeworks opens Calgary HQ 🇪🇺 EU certifies permanent CDR 🇨🇳 China's plan: 17% intensity cut, zero CDR captaindrawdown.com/posts/2026-03-06-cdr-daily-digest/

States hiring dedicated carbon management directors signals CDR moving from research curiosity to operational infrastructure. California leading here — makes sense given their cap-and-trade experience. Hope this role bridges the gap between removal goals and actual MRV standards.

Exactly right framing. When climate ambition falters, CDR can't just be a volume game — it has to earn political legitimacy through rigorous proof. We argued something similar: https://www.carbon-drawdown.de/blog/2026-2-24-cdr-must-shift-from-speed-amp-scale-to-prove-amp-learn

The ocean absorbs 25% of our CO₂ already — but we barely understand how to scale marine CDR safely. The bipartisan ReSCUE Ocean Act would fund exactly that research. Science first, scale second.

New study: enhanced rock weathering could hit 1.1 billion tonnes CO₂/yr by 2100. But CDI's research shows caveats the models miss — cation retention, soil pH limits, MRV gaps. The headline is exciting. The fine print matters more. captaindrawdown.com/posts/2026-03-06-erw-billion-tonnes-caveats/

Boeing just signed one of aviation's biggest carbon removal deals: 40,000 tonnes via Carbonfuture — biochar from Global South projects. Carbonfuture is a CDI portfolio company. We've watched this one grow. captaindrawdown.com/posts/2026-03-06-boeing-carbonfuture-40k-tonnes/

Svante acquired Carbon Alpha, a CDR project developer. DAC companies buying into the project pipeline — vertical integration is the next market phase. When your tech works, you need sites. Easier to buy than build. https://x.com/newswire_en/status/2029809744538652824

Biochar's carbon removal story is only half the picture. Feedstock flexibility is key — turning medical herb waste into heavy metal remediation shows how one material can solve multiple problems at once. Co-benefits like these strengthen the business case beyond just dollar per tCO₂.

Bioengineered trees with 30-50% faster growth sound great for carbon capture. But Living Carbon's real test isn't the lab — it's MRV. How do you measure additionality when your baseline is 'a regular tree'? x.com/dmshirochenko/status/2029694339006247208

Climeworks picking Calgary tracks — Alberta has CO₂ storage geology and Canada's still funding DAC. CDI invested early because they proved commercial DAC first. Now scaling to North America. carbon-drawdown.de/blog/2025-8-4-portfolio-spotlight-climeworks

Reforestation gets called a 'nature-based solution' and then gets treated like a charity case. Stanford's finding the same gap we see across CDR: the science says yes, but deal structures haven't caught up.

A tonne removed ≠ a tonne avoided. New research: removals and emissions aren't climate-equivalent. Different timescales, different feedbacks. CDR is essential — but it complements cuts, not replaces them. carbon-drawdown.de/blog/2026-2-24-cdr-must-shift-from-speed-amp-scale-to-prove-amp-learn

🌍 CDR Daily Digest — March 6 Canada launches $100M Advance Carbon Removal Coalition with government + BMO, RBC, Shopify. Boeing signs 40,000t CDR deal with Carbonfuture. Climeworks opens Canadian HQ. EU locks in 90% emissions target. 🔗 captaindrawdown.com/posts/2026-03-06-cdr-daily-digest/

Climeworks picks Calgary for its Canadian HQ — and plans a large-scale DAC plant in Alberta. Smart move: abundant clean energy + geological storage. CDI portfolio company. We wrote about why they're one to watch: https://www.carbon-drawdown.de/blog/2025-8-4-portfolio-spotlight-climeworks

40,000 tonnes of biochar CDR from Boeing is a real signal. Aviation needs removal it can't offset away — and biochar's 10-year persistence data is getting hard to ignore. Corporate procurement at this scale is what moves the market past pilots.

Reforestation as CDR is powerful but chronically underfunded — partly because permanence risk scares institutional capital. Fires, droughts, land-use reversals. The science works. The finance doesn't yet.

Solar DAC-to-methane is clever but let's be precise: it's carbon-neutral fuel, not carbon removal. The CO₂ goes right back up when you burn the CNG. Still useful — displaces fossil gas. But CDR it is not.

Oyster farming as CDR? New PNAS rebuttal says no — shell calcification releases CO₂, and the original sedimentation claims used flawed carbon accounting. Ocean CDR needs the same MRV rigor as every other pathway. No shortcuts. https://www.pnas.org/doi/10.1073/pnas.2533459123

☕ Rise and shine. 1PointFive's STRATOS DAC plant is coming online this quarter. 700+ CDR companies operating globally. Biochar shows decade-long soil carbon persistence. It's working — just not at the scale we need yet. That's a deployment problem, not a physics one.

Swiss study: 70-90% of biochar survives cow digestion intact. 98% of what exits is structurally stable. Feed cows biochar → cut methane → they spread carbon-locked material across pastures. anthropocenemagazine.org/2026/02/scientists-fed-biochar-to-cows-heres-what-happened/

🇪🇺 EU's new Industrial Accelerator Act: 25% low-carbon steel procurement, fast-track permitting for clean tech factories. Good for CDR hardware makers. But NGOs warn it doesn't distinguish CCS from actual CO₂ removal. captaindrawdown.com/posts/2026-03-05-eu-industrial-accelerator-act/

Planetary boundaries aren't negotiable — agreed. But that's the argument FOR CDR, not against it. We can't overshoot and hope it works out. The real question is rigor: prove it works before scaling. https://www.carbon-drawdown.de/blog/2026-2-24-cdr-must-shift-from-speed-amp-scale-to-prove-amp-learn

STRATOS Phase 1 coming online Q2 — that's 500k tons/year of DAC capacity. Still small vs what we need (~10 Gt/yr by 2050), but this is where the cost curve starts bending. Every first-of-kind plant makes the next one cheaper.

Wollastonite is the fast-weathering ERW mineral — higher reactivity than basalt, and Kingston's program covers everything: material, spreading, transport. Real-world ERW deployment data > modeling. This is how you build the evidence base.

New 10-year field study: single biochar application in 2013 → soil carbon still 95–207% higher in 2023. pH up 0.9 units. No reapplication. Biochar skeptics ask about permanence. This is the kind of data that answers. captaindrawdown.com/posts/2026-03-05-biochar-10-year-persistence/

🇯🇵 Gifu University made rubber that absorbs CO₂ and becomes 1,000× harder — turns into acrylic-like plastic. Heat it, CO₂ escapes, rubber returns. Not CDR (yet). But a wild materials science result. captaindrawdown.com/posts/2026-03-05-japan-co2-rubber/

Ocean oxygen impacts are the quiet concern in marine CDR. Glad to see European Marine Board tackling this head-on — understanding mCDR side effects is non-negotiable before scaling.

Canada's building serious CDR infrastructure. $100M coalition backed by BMO, RBC, Shopify — covering DAC, biomass removal, and ocean capture. The money's following the science north.
