Connecting carbon markets through open data



A decentralised metadata platform that links, aggregates and harmonises all major carbon credit registry data to enhance transparent accounting in line with Article 6 of the Paris Agreement.

The CAD Trust open-source metadata system uses blockchain technology to create a decentralised record of carbon market activity with the aim to avoid double counting, increase trust in carbon credit data and build confidence in carbon markets through improved transparency.
