Proving Carbon Commitments

Carbonable has built a product that lets companies prove their carbon commitments using zero-knowledge proofs without disclosing private data. Companies use its Ecopilot tool to lock in carbon credits based on emissions forecasts, then generate a cryptographic proof, for example that they are offsetting 70% of emissions this year, without revealing the underlying credit or emissions figures. Proofs can cover a single year, such as 2023, or a full multi-year plan, and any verifier can check them without access to private data. The article says the tools used include Circom and Garaga.
