Home Carbon Projects Enhanced Weathering
Enhanced weathering involves the large-scale application of finely ground minerals, such as olivine or basalt, to land surfaces or marine environments. These minerals react with atmospheric CO₂ through mineral carbonation, forming stable carbonates that permanently store carbon.
This process, which naturally unfolds over geological timescales, is significantly accelerated through human intervention. By enhancing this reaction, the project contributes to long-term carbon sequestration while improving soil fertility and water quality.
Project Impacts

Climate & Environment
- Carbon Sequestration: Accelerated mineral weathering removes atmospheric CO₂ permanently
- Soil & Water Quality: Releases essential nutrients that boost soil fertility and supports plant growth
- Biodiversity Protection: Reduces ocean acidification and strengthens marine habitats to support healthier ecosystems
Social & Economic
- Local Economic Benefits: Creates new job opportunities while promoting sustainable land management practices
Project Type: Carbon Removal – Enhanced Weathering





Project Facts
Project Details
Enhanced weathering applies finely ground minerals, such as olivine or basalt, to land or marine environments at scale. These minerals react with atmospheric CO₂ through mineral carbonation, forming stable carbonates that permanently store carbon.
Naturally occurring over geological timescales, this process is significantly accelerated through human intervention. By enhancing the reaction, the project enables long-term carbon sequestration while improving soil health and water quality.
About the Project
Enhanced weathering is a scientifically proven carbon removal method that accelerates natural geochemical processes to permanently sequester CO₂. The project sources and processes silicate minerals, applying them to land or ocean environments where they react with atmospheric carbon to form stable carbonates.
Beyond CO₂ removal, this approach delivers co-benefits: improving soil health, enhancing marine biodiversity, and supporting local economies through sustainable job creation.
Carbon Removal & Permanence
Enhanced weathering provides a durable carbon sequestration pathway, locking carbon away for hundreds to thousands of years. Unlike emission reduction efforts that only avoid new emissions, this project actively removes CO₂ from the atmosphere.
- Carbon sequestration permanence ranges from 100+ to 1,000+ years
- Sequestration is monitored and verified through independent third-party audits
- Carbon credits generated are backed by the Puro.earth Standard, ensuring high-quality removals
Environmental & Social Benefits
