You always mention carbon footprint of "materials" being by far the biggest chunk of our overall carbon footprint.

However, I have no clue what carbon footprint of "materials" actually is. What does it entail? What exactly causes carbon emissions that fall into this "materials" category? Is it power for some machines? Is it chemical processes that somehow emit carbon dioxide? Is it any kind of transport that happens before a piece of material is in the factory?

(As you maybe can tell I have no clue what actually happens until a shoe is produced)
