Values change when there are changes in the way the product is made. 

Carbon footprints are based on many variable factors - where a product is made, what fuels that energy system uses, how far it has to travel to reach its end destination. For this reason, the carbon footprint of any individual product will change. The numbers provided are overall representations of a format’s carbon footprint to give context about what is generally higher or lower, not individual calculations for your own individual situation.

These comparisons have been made against the full life cycle of each listed format.
