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