Understanding Microbial Carbon Mineralization

https://www.senken.io/academy/microbial-mineralisation

* Microbial mineralisation uses microbes to accelerate natural rock weathering and lock atmospheric CO2 into stable carbonate minerals on geological timescales—offering one of the most durable carbon removal pathways available today. Compared to reforestation and soil carbon (both less than 100 years permanence) or even biochar (less than 1000 years under most conditions), microbial mineralisation offers the kind of geological-scale storage that satisfies both SBTi's "novel removal" requirements and the CFO's question about reversal risk. Senken's 600+ datapoint Sustainability Integrity Index provides a systematic way to evaluate microbial mineralisation projects across five dimensions: basic project details (methodology, registry, third-party review), carbon impact (permanence, additionality, baseline, leakage), beyond-carbon co-benefits (soil health, community impact, governance), reporting process (MRV transparency and frequency), and compliance and reputation (external ratings, public track record, alignment with ICVCM Core Carbon Principles). If you want support navigating microbial mineralisation procurement, evaluating projects, or building an Oxford- and CSRD-aligned carbon removal portfolio, Senken's team can help.

### Consultation. # Microbial Carbon Mineralisation. * Consultation Period 11 Jun 2025 - 10 Jul 2025. * Submission Deadline Jul 10, 2025 — 16:00 (Europe/Zurich). ## Introduction. This methodology is applicable to project activities that remove and durably store carbon dioxide (CO₂) via application of a microbial inoculant to existing cropland. This approach leverages the mutualistic relationship of beneficial soil bacteria and plant roots to capture CO₂ and convert it into soil inorganic carbon (SIC). The methodology outlines the requirements and procedures for quantifying and monitoring the associated carbon removals. ## Consultation document. ## Submission process. Please, use the form here below, to submit your feedback, before the 10 July at 18:00 CEST. ### Gold Standard Newsletter Subscription. Stay updated on our latest news and more.

The Importance of Soil Microbes in Carbon Sequestration and Long-term Soil Accrual – Center for Regenerative Agriculture and Resilient Systems – Chico State

For example, scientists used to think that the carbon in the soil came mostly from the decomposition of plant residue; but now these microorganisms are increasingly seen as playing a crucial role(opens in new window) in photosynthesis, in the creation of soil organic carbon, in carbon sequestration, and how that interacts with climate change. Microbial necromass is thought to be the main component of soil organic carbon sequestration(opens in new window), with fungal dominant soils showing the highest concentration of soil carbon in most studies. So far, several studies(opens in new window) indicate that agricultural practices that focus on creating optimal conditions for higher fungal to bacterial ratios have potential for improving soil carbon sequestration. In terms of carbon sequestration, they are essential through their roles in decomposing organic matter, forming stable soil organic matter and aggregates, and supporting plant growth and nutrient cycling.
