Loam Bio is an Australian climate-bio company aiming to 'strengthen crops' carbon fixation with the power of microbes, turning farmland into a giant carbon sink.' Founded in 2019–2020 in Orange, NSW, on soil-microbe research from the University of Sydney, its flagship CarbonBuilder inoculates seeds with endophytic fungi (dark septate endophytes), converting the CO2 crops take from the air, via their roots, into a 'stable, hard-to-decompose form' stored in soil for a long time. Alongside it, SecondCrop measures and verifies that soil carbon and turns it into carbon credits as farmer income. It raised $150M, the most for Australian agritech (with backers including the government-linked Clean Energy Finance Corporation), and has run many field trials in Australia, the US, Canada and Brazil. Its banner: gigaton-scale carbon removal using farmland worldwide.

Loam Bio: Using microbes to strengthen crops' carbon fixation—climate tech at the projected stage. At present independent evidence is scarce, so the assessment is on hold. Unconfirmed concerns are placed under “Watching.” (As of 2026-Q3; estimate based on public information.)

- Independent verification of the carbon effect in real-world crops; establishing MRV (permanence/additionality/rigor); ensuring carbon-credit quality; scaling from field to implementation.
A second look
The intended plus is removing atmospheric CO2 and increasing soil carbon through farmland, and the resulting soil health and resilience (Nature), grounded in University of Sydney science, CEFC investment, and multi-country trials. But at present it is at the projected stage—scientists themselves say 'it is doubtful whether microbial-fungi field trials translate into a meaningful carbon effect in real-world crops, and further verification and monitoring are needed'; soil-carbon MRV (measurement, reporting, verification) is unestablished, with permanence, additionality and rigor varying greatly between protocols; and there is industry debate over the integrity of the carbon-credit model itself. There is no confirmed minus, but because the plus realized is not yet established, it is on hold.

How to read this assessment
- Reachable upper bound (ceiling): a confirmed − sets the ceiling, and independently verified + decide the position within it. + do not cancel out −.
- The weight of evidence is not symmetric: only confirmed − are counted; the volume of disputes or allegations goes under “Watching.” + are counted from independent evidence, while an organization’s own PR is treated as “reference.”
- Size is not value: scale is not used in the assessment. Matters that stay within money or competition—investors, shareholders, sanctions, trade secrets—are also excluded.
- The letter (assessment) and certainty (how reliable the information is) are separate axes.
This is a translation; the Japanese version is authoritative. The assessments here are generated automatically by AI based on published criteria. The operator does not alter individual results. Because they are AI-generated they may contain errors, and they are opinion and commentary, not statements of fact. Where evidence is insufficient, the entry is marked “On hold.” Requests for correction are accepted via the form.
Terms: Narrative Value = an assessment (A–G) of the distance between the story an organization tells and its reality / Ceiling meter = a visualization of the reachable upper bound / Watching = unconfirmed matters not counted / Protected stakeholders = people, animals, nature, and future generations. | Generated by: AI | As of: 2026-Q3 | Back to top
