Fuente: WIPO "sustainability" Systems and methods for tracking and verifying sustainability data are provided. A system may receive a first transfer request message associated with a conveyance of a first item from a first entity to a second entity. The message may include first sustainability data associated with the first item, which may be a production input of a second item. The system may then obtain second item composite sustainability data to be included in a second transfer request message associated with a conveyance of the second item from the second entity to a third entity. The system may then verify the second item composite sustainability data by determining that this data includes at least a portion of the first sustainability data and second item production sustainability data. The system may then send the second transfer request message. The second transfer request message may include the second item composite sustainability data.
