Isometric, today recognized as the world’s leading carbon removal registry, has hit a major milestone—signing its 100th supplier, Flux. Over the past year, the number of organizations working with Isometric has more than quadrupled. That growth highlights one clear trend: the market is demanding transparency, scientific rigor, and fast verification.
Flux Joins as the 100th Supplier
Flux, a fast-rising Enhanced Weathering company, is on a mission to remove five million tonnes of CO₂ by 2030. Their model is built around farming partnerships. By supplying alkaline rock powders, Flux provides dual benefits: capturing carbon from the atmosphere while enhancing soil health.
These rock powders neutralize acidity and add nutrients, leading to improved soil fertility and stronger yields. For agricultural communities, this means better productivity alongside climate action, making Enhanced Weathering especially compelling.
Sam Davies, CEO and Co-Founder of Flux, said,
“Partnering with Isometric helps us take a big step toward our mission of deploying Enhanced Weathering at scale across Africa. Their scientific rigor, transparent approach, and robust verification process align perfectly with how we operate, giving buyers confidence in the climate and community impact our credits deliver.”
Why Isometric’s Standard Matters?
Suppliers joining Isometric must follow the Isometric Standard, widely regarded as one of the toughest in the carbon market. To qualify, credits must be:
-
Durable – Stored securely for centuries or millennia.
-
Additional – Delivering removals that would not have happened otherwise.
-
Scientifically Verified – Using advanced methods with quantified uncertainty.
Each Verified Credit logged on the Isometric Registry represents real net CO₂ removals. Importantly, all data, calculations, and supporting evidence are publicly available, giving buyers complete transparency.
In December 2024, Isometric issued the first-ever verified EW credits under its Enhanced Weathering in Agriculture Protocol. This breakthrough set a new benchmark for MRV (monitoring, reporting, and verification), proving EW credits can meet the highest integrity standards.
Raising the Bar for Enhanced Weathering
Enhanced Weathering accelerates a natural process. In nature, CO₂ dissolves in rainwater, reacts with rock minerals, and is stored in the oceans as bicarbonates for over 10,000 years. Grinding rocks into powder and spreading them on farmland significantly speeds up this process.
Compared to reforestation, which risks reversal from wildfires or land-use change, EW offers a more permanent and scalable solution. It also brings direct co-benefits: healthier soils, better yields, and rural job creation.
For years, EW’s biggest challenge was credibility. Without rigorous MRV, buyers hesitated to engage. Isometric’s protocol has changed that, requiring direct measurement and statistical confirmation that removals have taken place. Each credit now represents one tonne of CO₂ permanently removed.
Concisely, among carbon removal pathways, EW is fast emerging as a leader. It offers:
-
Permanence – CO₂ is locked away for millennia.
-
Scale – Gigaton potential at relatively low cost.
-
Co-Benefits – From soil health to food security to rural jobs.
Unlike costly DAC or fragile natural solutions, EW sits at the intersection of affordability, scalability, and durability. Verified EW credits bring credibility to this promise.
Isometric’s Role in Market Integrity
The carbon credit market is undergoing a major reset. BloombergNEF forecasts supply could rise 20–35x by 2050, creating one of the largest financing tools for global decarbonization. But that future depends on integrity and governance.
Significantly, CDR.fyi, in its Q2 2025 Durable CDR Market Update, reported the sector’s strongest quarter yet. Contracts reached 15.48 million tonnes of carbon removals—exceeding the combined total of all prior quarters at 13.6 million tonnes.
Additionally, deliveries also rose sharply, with 113.7 thousand tonnes supplied in Q2, a 39% jump over Q1 2025 and the second-highest quarterly delivery on record.
Isometric’s role is pivotal in the carbon removal market. By enforcing rigorous protocols and making data public, the registry ensures that credits are trustworthy. Since 2022, its mission has been building confidence in a market that too often suffers from quality questions. And the 100-supplier milestone marks real progress in this sector.
