Enhanced Weathering

Project Facts

Project Details

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 carbonate compounds that permanently store carbon. 

This process, which naturally occurs over geological timescales, is significantly accelerated through human intervention. By enhancing this reaction, the project contributes to long-term carbon sequestration and improved soil and water quality. 

About the Project

Enhanced weathering is a scientifically backed method of carbon removal that leverages natural geochemical processes to sequester CO₂. The project sources and processes silicate minerals, which are then applied to land or ocean environments to react with atmospheric carbon and form stable carbonates. 

This approach not only removes CO₂ but also provides additional environmental benefits, such as improving soil health, enhancing marine biodiversity, and supporting local economies by creating sustainable job opportunities. 

Carbon Removal & Permanence 

Enhanced weathering is a long-term carbon sequestration solution, ensuring carbon is permanently stored for hundreds to thousands of years. Unlike emission reduction projects that prevent further 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 

Climate & Environment 

• Removes CO₂ effectively, reducing greenhouse gas concentrations. 
• Enhances soil fertility, reducing reliance on chemical fertilisers. 
• Slows ocean acidification, supporting marine biodiversity and coral reefs. 

Social & Economic

• Encourages sustainable agricultural practices. 
• Supports scientific research into scalable carbon removal solutions. 
• Creates local employment opportunities in mining, processing, and land application. 

Collaborations

The Enhanced Weathering project is certified under the Puro.earth Standard, ensuring transparency and credibility in carbon removals. Anthesis is a founding member of ICROA, which independently verifies working methodologies and project quality. 

By leveraging cutting-edge scientific research, carbon finance, and sustainable land-use practices, Anthesis continues to drive impactful climate solutions through enhanced weathering.
