A solution for tracking the carbon footprint value of an object as the object is manufactured and/or transported. This value may be stored in a tag associated with the object. Thus, the object can track its own carbon footprint, e.g., using the tag. Alternatively, the values are stored in a database with an entry associated with a particular object. The final composite value, e.g., the sum of the intermediate values associated with manufacturing steps, components, transportation steps, and disposal, may be used, e.g., seen, by the consumer or retail store. The store may use such values to arrange objects by footprint value on a shelf or in a store, or for other purposes. Therefore, the disclosure enables manufactures of products to track the carbon footprint for their products as the products are being produced and transported.
