}Pre-Markup
Example of a certification for carbon footprint of a product with a W3C verifiable credential (https://w3c.github.io/vc-data-model). The certification information is copied and embedded within the Product. Note the use of id and type instead of @id and @type, using the mappings defined in https://www.w3.org/ns/credentials/v2, for lighter-weight credential-type specific processing.
