Assessing weathering rocks viability as a pathway to premium carbo credits

The increasing demand for high-quality carbon dioxide removal (CDR) solutions has created new opportunities for integrating enhanced weathering technologies with blue carbon ecosystems. This study assesses the viability of employing olivine-rich rocks in mangrove sediments as a pathway for generating carbon credits through enhanced weathering and long-term carbon sequestration. Olivine, a magnesium silicate mineral, naturally consumes atmospheric carbon dioxide during weathering, producing dissolved bicarbonate ions that can be transported and stored in marine environments over geological timescales. When applied to mangrove sediments, olivine weathering may complement the substantial carbon storage capacity of mangrove ecosystems by increasing alkalinity, enhancing carbon capture, and potentially mitigating local ocean acidification.

The research evaluates the technical, environmental, and economic feasibility of olivine application within mangrove systems, focusing on weathering rates, carbon removal efficiency, sediment geochemistry, ecological impacts. Field measurements, laboratory analyses, and carbon accounting models are used to quantify net carbon dioxide removal and assess compliance with emerging carbon credit standards.
