Abstract: A tracking system and method for incorporating sensor measurements into a blockchain are provided. The system comprises at least one meter for measuring GHG emissions and generating measurements related to the emissions, at least one server communicating with the at least on meter over a peer-to-peer network. The peer-to-peer network is implemented as a distributed ledger of the blockchain. The at least one meter transforms the measurements into at least one carbon block and writes the at least one carbon block to the distributed ledger. The at least one carbon block is distributed to the at least one server via a blockchain protocol.
