Carbon impact

The ZeroEx Enhanced Rock Weathering (ERW) project accelerates the natural process of rock weathering by spreading finely crushed basalt on agricultural lands in Germany’s Eifel region. Over its first decade, the project is expected to sequester 75,000 tons of CO2-equivalent emissions annually by applying 22,854 metric tons of basalt in 2024 alone. Each ton of basalt enhances carbon removal by converting atmospheric CO2 into stable bicarbonate, which is stored for over 10,000 years in soils and oceans.

By leveraging basaltic rock powder - a byproduct of local quarries - the project avoids the need for additional mining and reduces emissions associated with traditional agricultural liming. The process also improves soil health, increasing fertility, water retention, and crop yields for local farmers, while supporting sustainable farming practices. Beyond its climate impact, the project fosters local economic growth by collaborating with 18 partner farms and creating opportunities in sustainable agriculture. ZeroEx’s approach exemplifies a scalable, circular solution that delivers measurable environmental, social, and economic co-benefits while advancing global net-zero goals.

Impact on local communities & environmental

The project brings tangible benefits to nearby communities by transforming basaltic quarry byproducts - often considered waste - into a valuable resource for carbon removal and soil enhancement. By spreading finely crushed basalt on agricultural lands, the project accelerates the natural weathering process, sequestering CO₂ as stable bicarbonate and preventing its release into the atmosphere. This creates a cleaner, safer environment for residents near quarries and farms, reducing air pollution and improving local air quality.

In addition to its climate impact, the project lowers the risk of soil degradation and supports sustainable farming practices by improving soil fertility, water retention, and crop yields. Beyond these environmental benefits, ZeroEx collaborates with 18 local farmers, creating economic opportunities and fostering regional growth. The initiative actively engages farmers and communities through consultations, transparent data sharing, and ongoing feedback channels, ensuring their concerns are addressed and building trust in the project’s long-term social and environmental benefits. This approach not only advances climate goals but also strengthens local resilience and sustainability.

What is Enhanced Rock Weathering?

Enhanced Rock Weathering (ERW) is a natural process accelerated by human intervention to remove carbon dioxide (CO2) from the atmosphere and store it long-term. When certain types of rocks, such as basalt, are exposed to air and water, they undergo a chemical reaction called weathering. During this process, CO2 from the atmosphere reacts with the minerals in the rock, forming bicarbonate ions that eventually make their way to the ocean, where they are stored for tens of thousands of years.

ERW projects speeds up this natural process by spreading finely crushed basalt or similar - a byproduct of local quarries - onto agricultural lands. Instead of leaving CO2 to accumulate in the atmosphere, the crushed rock reacts with rainwater and soil, converting atmospheric CO2 into stable bicarbonate. This process not only sequesters carbon but also improves soil health by increasing fertility, water retention, and crop yields.

Without intervention, rock weathering occurs slowly over geological timescales. By grinding the rock into fine powder and spreading it on fields, ERW projects enhance the surface area available for reactions, significantly accelerating carbon removal.

Certification Standard


This project is verified through isometric carbon removal, a cutting-edge approach to permanently sequestering CO₂ from the atmosphere. Isometric methods - such as enhanced rock weathering and mineralization - transform captured carbon into stable mineral forms, ensuring durable storage for 100+ years.

Regreener's Rating

The ZeroEx enhanced rock weathering project is a standout example of how carbon removal can be both grounded in science and grounded in reality. By leveraging the natural reactivity of basalt, it doesn’t just promise permanence - it delivers it, converting CO₂ into stable bicarbonate on geologic timescales. What makes this approach compelling isn’t its novelty, but its pragmatism: it works with existing agricultural systems, turns waste into a resource, and enhances soil health as a core part of its design. The project’s true strength lies in its integration of rigor and collaboration. Advanced MRV techniques like Self-Integrating Accumulators ensure transparency, while its engagement with farmers transforms carbon removal from a technical process into a shared opportunity. Too many climate solutions operate in silos; ZeroEx proves that durability, scalability, and community benefit can, and should, go hand in hand. For buyers seeking more than just offsets, this is carbon removal done right: verifiable, scalable, and embedded in real-world impact.
