CarbX offers Carbon Storage Options (CSOs), a novel financial instrument representing a claim on verified, future CO₂ storage. These call options are tied to the progress and development of specific CCS projects, providing investors with a risk-priced mechanism to secure storage capacity and benefit from the growth of the CCS market. Tranches of CSOs are issued over time, reflecting project milestones, and are traded on the CarbX platform, creating liquidity and attracting investment.
