[C]Worthy is building open-source, science-backed tools to support the growth of trustworthy, scalable ocean-based carbon removal. Our mission is to deliver trustworthy, science-backed tools for Monitoring, Reporting, and Verification (MRV). We’re adapting advanced oceanographic models to provide scientifically credible methods for quantifying carbon removal and assessing ecosystem impacts from CDR deployments. These capabilities are delivered through our open-source software platform, C-Star, which is designed to ensure standardization, auditability, and transparency—foundational elements of a high-integrity CDR market. We work closely with commercial CDR companies, registries, and buyers to provide tools that meet requirements for site characterization, deployment design, and robust MRV. In parallel, we partner with the academic community to advance the science of CDR quantification and integrate cutting-edge capabilities into C-Star. We aim to establish a new community of practice that fosters continuous research and development, supports tools that track the best available science and technology, and drives capacity-building initiatives that promote inclusive access and broad participation in the future of ocean-based CDR.
