Five stories today — ranging from a serious accounting warning for biomass credits to the EU putting rules on paper for carbon removal certification.

⚠️ Biomass Carbon Credits Face an Accounting Crisis

Biomass Carbon Credits Face Accounting Crisis Before They Even Scale

88% of all carbon removal credits sold involve biomass. A new CATF report examined 25 certification protocols for biomass-based CDR — and found nearly all have significant accounting flaws. The voluntary carbon market already crashed once from sloppy accounting in the offset era. CDR can’t afford a repeat. Getting biomass carbon accounting right now, before the market scales further, isn’t optional.

🇧🇴 Bolivia Gets Its First Large-Scale Biochar Facility

Bolivia Biochar Facility — 70,000 Tons CO₂/Year

Empacar, Puro.earth, Cula, and Bioflux are building a biochar production facility in Bolivia that will process local sawmill waste into stable carbon. Target: 70,000 tonnes CO₂ removed per year, with first Puro.earth-certified credits expected in 2027. CDR infrastructure in Latin America continues to grow — quietly but steadily.

🐚 What Happens to Mussels When You Add Alkalinity?

Ocean Alkalinity Enhancement & Mussel Shell Study

New research examined how ocean alkalinity enhancement (OAE) affects Mytilus edulis — common blue mussels. Scientists compared shell microstructure and molecular responses under acidified versus alkalinized seawater. For OAE to scale, we need evidence that adding alkalinity doesn’t just store carbon but also avoids harming marine ecosystems. This study adds a data point to that essential safety question.

🔍 Georgia Tech: CDR Needs Radical Transparency

Georgia Tech Research on CDR Transparency

Georgia Tech researchers argue that carbon removal won’t earn public trust or sustained policy support without radical transparency. They mapped which CDR pathways have the clearest benefits, what they actually cost, and where transparency gaps do the most damage. The takeaway: opacity isn’t just a PR problem — it undermines the entire field’s ability to attract funding and public acceptance.

🇪🇺 EU’s CRCF Gets Its Technical Rulebook

EU Carbon Removal Certification — Technical Rules Published

The EU’s Carbon Removal and Carbon Farming (CRCF) Regulation now has implementing rules. Regulation 2025/2358 specifies exactly how certification schemes, auditors, and accreditation bodies must operate. Europe is moving from “we should certify carbon removal” to “here’s how.” While the US stalls on climate policy, the EU keeps building the regulatory infrastructure for a functioning CDR market.

Also Noteworthy

Stories we tracked but didn’t cover as full posts today:

  • Google signed a 200,000-ton biochar CDR deal with AMP — one of the largest single removal purchases ever. AMP uses AI-powered waste sorting + pyrolysis. Multiple outlets covered this (Carbon Herald, ESG News) — we covered it in yesterday’s digest.
  • Tapestry (Coach, Kate Spade) signed a 10-year partnership with Climeworks — long-term corporate CDR commitments like this are exactly what the market needs for investment certainty.
  • New EGU abstract on enhanced weathering + organic carbon — how different organic carbon sources interact with metal slag reactivity and inorganic carbon dynamics. One for the EW researchers.
  • Marine carbon removal gains momentum but faces scaling and responsibility questions (Carbon Herald).
