Five original posts today — anchored by a Princeton study that challenges one of CDR’s most relied-upon pathways, and bookended by a fashion-industry-first DAC deal and new soil science that matters for enhanced weathering.

⚠️ BECCS May Emit More Than Natural Gas for Decades

BECCS May Emit More Than Natural Gas for Decades, Princeton Study Finds

A preprint from Princeton, Hong Kong University, and WRI drops a bomb on bioenergy with carbon capture and storage. Their analysis: when you account for land-use change, supply chain emissions, and the decades-long carbon payback period of growing new biomass, BECCS could produce higher net emissions than just burning natural gas — for decades. That’s a problem, because BECCS underpins a large share of IPCC scenarios that keep warming below 2°C. The paper doesn’t say BECCS can never work, but it argues that the conditions under which it delivers net-negative emissions are far narrower than most models assume.

🏗️ Coach and Kate Spade’s Parent Signs 10-Year DAC Deal

Tapestry Signs 10-Year Carbon Removal Deal With Climeworks

Tapestry — parent company of Coach, Kate Spade, and Stuart Weitzman — has signed a decade-long carbon removal agreement with Climeworks. It’s the first deal of its kind from a North American fashion company. While the exact tonnage hasn’t been disclosed, the 10-year timeframe signals genuine commitment rather than a one-off offset purchase. Fashion is one of the hardest sectors to decarbonize (complex global supply chains, fast-moving inventory), which makes durable CDR purchases a logical piece of the puzzle.

🇨🇳 Chinese Startup Claims Competitive Synthetic Fuel From Air

Chinese Startup Claims Competitive Synthetic Fuel From Air and Water

Shanghai-based Carbonology, co-founded by a former Tesla VP, says it can produce synthetic petrol, diesel, and jet fuel from air and water at market-competitive prices. The claimed cost would undercut most Western e-fuel projects by a wide margin. Details are thin — no peer-reviewed data, no independently verified cost numbers. Worth watching, but the CDR community has been burned by bold claims before. If Carbonology’s process actually works at the stated economics, it would reshape the entire synthetic fuel landscape.

🔬 How Organic Carbon Changes Enhanced Weathering Reactivity

How Organic Carbon Changes Enhanced Weathering Reactivity

New EGU 2026 research digs into what happens when you combine crushed rock with organic amendments like compost and biochar — which is exactly what real-world farming looks like. The findings: the interaction between rock type and organic carbon source matters more than either factor alone. Metal slags reacted differently depending on whether compost or biochar was the amendment. For enhanced weathering companies relying on simplified lab models, this is a wake-up call. The soil is more complicated than the spreadsheet.

💡 CDR Misconception #2: DAC Uses Too Much Energy

CDR Misconception #2: DAC Uses Too Much Energy to Ever Work at Scale

Second installment in our misconception series. Yes, direct air capture needs substantial energy — roughly 1,500–2,000 kWh per ton of CO₂ for today’s leading systems. But “a lot” is relative. Global renewable capacity is growing faster than anyone predicted, and DAC energy costs are falling as the technology matures. The real question isn’t whether DAC uses energy, but whether the energy system can grow fast enough to supply it alongside everything else.

What We Didn’t Cover (But You Should Know)

  • Google signed a 200,000-ton biochar CDR deal using AI-optimized waste-to-carbon processes — another signal that Big Tech’s carbon removal purchasing continues to accelerate.
  • New OAE research mapped optimal global regions and uneven costs for ocean alkalinity enhancement — the economics vary wildly by geography.
  • CATF evaluated biomass CDR protocols and found widespread accounting weaknesses — echoing yesterday’s coverage of the biomass credit accounting crisis.
  • Carbon Business Council launched a Direct Storage of Biomass coalition — pushing buried biomass as a CDR pathway alongside biochar and BiCRS.
