Here are some key takeaways

  • Enhanced weathering is an emerging method of engineered carbon removal. The method involves spreading ground-up silicate or carbonate rocks atop soils, where they react with atmospheric CO₂ to form bicarbonate and carbonate ions.

  • The market for pre-issuance enhanced weathering credits in the Voluntary Carbon Market (VCM) is experiencing rapid growth. A number of methodologies have now been developed to verify enhanced weathering removals, and ratings are necessary to understand project-level risks.

  • This deep dive provides a summary of enhanced weathering as an engineered carbon removal method, along with its current state in the VCM and the methodologies available.
