New
Carbon data is everywhere but none of it speaks the same language. COMET is a free, open, community-governed meta-ontology that maps product-level carbon footprint data, supply chain verification endpoints, Environmental Attribute Certificates, and market-pricing signals into a single interoperable knowledge graph. Seven semantic layers from core identity primitives to market pricing signals, aligned with ISO 14067, PACT v3, GHG Protocol, EU CBAM, and more.
The ontology is accompanied by a 200-step Master Build Plan across 10 expert panels, a 30-slide stakeholder deck, and a 36-month roadmap to v1.0 stable. COMET builds on the Carbon at Risk (CaR) framework, extending risk measurement into a full ontological infrastructure for treating carbon as a financially tradeable, risk-adjusted asset class.
