Environmental attributes for materials

A method for generating a digital asset associated with an output material, wherein the output material is produced from one or more input material(s) through one or more chemical process(s) of a chemical production network, wherein the one or more input material(s) and/or the one or more chemical process(s) are associated with environmental attribute(s), the method comprising:

• generating the digital asset by providing a decentral identifier associated with the produced output material and one or more environmental attribute(s) associated with the one or more input material(s) and/or the one or more chemical process(s) used to produce the output material and linking the decentral identifier and the environmental attribute(s), wherein the decentral identifier is linked to a digital representation of the one or more environmental attribute(s), wherein the digital representation includes a representation for accessing the one or more environmental attribute(s) or parts thereof, and wherein the one or more environmental attribute(s) are stored in a data base associated with the output material producer for access by an output material user;
• and
• providing the digital asset in association with the produced output material, wherein environmental attribute(s) associated with the output material are made accessible to a user of the output material through the digital asset.
