Cascade Climate has doubled the available data in its ERW Data Quarry by adding datasets from diverse agricultural systems in India, Brazil and Germany. The effort aims to address gaps in measurement, reporting and verification by improving transparency and access to real-world deployment data. Full article >>
Terradot is acquiring the assets of U.S. enhanced rock weathering developer Eion, adding more than 100,000 contracted carbon removal credits and an established olivine deployment platform. The combined company aims to strengthen financeability and delivery certainty as the sector shifts toward larger, industrial-scale programs. Full article >>
In western Germany, ZeroEx is spreading waste basalt fines from nearby quarries on farmland to remove CO2 through enhanced rock weathering while keeping emissions low and farmers cost-free. The project stands out for its monitoring approach, which tracks calcium and magnesium ions to support a ten-year crediting period and aims to improve measurement credibility in carbon markets.

A new review argues that today’s methods for measuring carbon removal from enhanced rock weathering are unreliable on working farmland. The authors say counting metal ions, not carbon, offers a simpler and more accurate way to verify climate credits. Full article >>
Eion’s first large-scale enhanced rock weathering project applied 15,000 tonnes of olivine to farmland in Mississippi and Louisiana, resulting in the issuance of 748 verified carbon removal credits under the Puro.earth ERW methodology. Backed by agribusiness partners and major carbon credit buyers, the company is betting that faster-dissolving olivine and rigorous measurement can scale ERW into a durable carbon removal pathway.

Terradot secured a multiyear agreement for Microsoft to purchase 12,000 tonnes of carbon-removal credits, giving the startup fresh backing to expand one of the most ambitious enhanced-rock-weathering research programs underway in Brazil. The funding will support denser soil and water sampling, watershed-level monitoring, and new low-cost verification methods as Terradot scales ERW operations across tropical farmland. Full article >>
Enhanced rock weathering is gaining traction in central India, where Mati Carbon has worked with more than 16,000 smallholder farmers to spread over 80,000 metric tons of basalt on croplands, supported by philanthropic funding, government grants, and growing carbon-credit sales. The company’s rapid expansion—capped by a $50 million XPRIZE win and new J.P. Morgan financing—signals mounting confidence that ERW can deliver both climate benefits and meaningful income gains for low-income farmers. Full article >>
New analytical tools—from immobile tracers and improved mass-spectrometry techniques to in-field bicarbonate sensors—are helping researchers more accurately measure how much CO2 is removed by enhanced rock weathering as large cropland projects scale up. These advances aim to cut costs, reduce sampling errors, and boost confidence in carbon-credit markets that depend on rigorous verification. Full article >>
